LGR 486 Update! 83MHz Pentium Overdrive CPU

LGR 486 Update! 83MHz Pentium Overdrive CPU


[“All the Good Things” by Nocturnal Spirits plays] Greetings and welcome to a
LGR Woodgrain 486 upgrade thing! And today, we’ve got the Intel
Pentium Overdrive Processor. “Makes your Intel 486
Processor-based PCs run faster.” Which is great, ’cause
that’s what I wanna do! Yeah, we’re gonna take the
Woodgrain 486’s AMD Am486 CPU that’s in there, running at 66 megahertz and turn it into a Pentium, of sorts. It’s kind of a weird thing,
you know, it takes a 486 and makes
it an 83 megahertz Pentium. Yeah, bit of an odd
frequency rating there, but that’s what Intel was doing, man. In the mid-90s they had all sorts of interesting Overdrive chips. And this one in particular
just attracted me to it. Yeah the PODP5V83, [chuckles] you know ’cause of
the weird rating 83 megahertz. And I’ve just never
messed with one of these Pentium Overdrives before, just 486 Overdrives
that take like a 486, 33 and turn it into a DX4-100 or whatever. And perhaps that would be more suitable for the Woodgrain 486, but
I’ve got this one here, complete in-box, it’s been sitting in its
sealed packaging for 25 years thereabouts. It was originally
launched in October 1995, maybe early 1996, depending
on where you look. But, back then it was $299 US dollars for just this upgrade chip, and that’s the equivalent of around $500 adjusted for inflation, so a bit pricey for just a CPU upgrade to the point where they
didn’t last on the market for too very long. And there were a log
critiques in the media about it being just being like, who the heck is this thing for? Average consumers found it too costly and businesses would rather
just get a new system. One IT guy was quoted as saying, “both a memory and hard
disc upgrade made sense “alongside a Pentium, “so if you do one, you have to all three. “And if you end up doing all three, “it’s just cheaper to buy a new system.” So, yeah I mean, all good points, I totally give all the points
to their logic. [laughing] But man, Intel was pushing
all the things it could do, I mean look at all these
software benchmarks, you know. 135%, 144%, 267% better in some programs, oh wow. Need help in selecting which one you need? I mean, look at all these things that you can do on the website. And yeah they had a website, you could go out on the web, the cyber spaces and you could
go and download this PDF, seriously, I did, it’s
still on archive.org. Yeah, the Intel Pentium
Overdrive Processor performance report. It’s 30 pages of like, just benchmarks and how cool it is to use
this thing in your 486 and there’s so much going on man. I don’t know, I don’t
really, I don’t know man. I just wanna play Duke Nukem 3D and Descent II and stuff. But, there were a lot of
serious people look at this and making paperwork. [laughing] Anyway, let’s go ahead
and get this unboxed because I’m curious what’s inside. [smooth jazz] Oh, the box itself is glued to itself. Actually looks like this
one was made in 1998. February 13th, wow that’s
almost exactly 22 years ago on the day I’m recording this. Okay, maybe they were on the market a little bit longer than I’ve read. I read they lasted through 1997, ’98 would have been pretty late to get an 83 megahertz Pentium. [laughing] They did not make that easy. Ooh, fresh Pentium Overdrive. No Bachman Turner included. Look at that. Yeah this was one of those, I believe, the heatsink
is permanently attached and there is a replaceable
fan clipped to the top, but, yeah they were serious
about the cooling on this thing. Just as an example, my AMD486 that’s in there right now does not require any cooling at all, it’s a 3.3 volt CPU, so it’s never had a
heatsink or fan or anything. But this, yeah they’re like “it’s 5 volt,” “it runs hot or whatever” “you just gotta make
sure it’s nice and cool.” Gotta wonder about the thermals in between the CPU and the
heatsink, but we’ll see. Let’s see here, wonder what we got, oh man. So we got a Stay In The
Loop registration card, the beginning of a valuable
relationship with Intel. Just what I’ve been looking
for around Valentines day. And we have the, wow this is
not something I was expecting. “Overdrive Processor
Demonstration and Diagnostics.” Okay. We’ve got a little
remover tool of some kind. Intriguing. And some paperwork. “Attention, Packard Bell systems,” oh dear, what now. “Serial numbers 450 and 470
require additional hardware.” Okay, we’re not putting
it in any of those. Yeah quick installation. I mean, yeah, pretty simple. Pretty pretty simple. It’s just a drop-in thing, man. Got some jumpers if we need, I guess a diagnostics
disk to check things out, that’s cool, I’m glad it comes with that. Lets see if the manual says
what to do with this doohickey. Oh, there’s an animated
demo, that’s gonna be good. Ha ha, I like animated demos. Okay, so that’s what that’s for, removing the processors from
the socket with no handle, haven’t seen one of those in a while. Not in a 486 anyway. So yeah, ah yeah, that makes sense. You got the little groves there, fits between the pins. Dang that’s cool, glad I have one of these, I’ve had some trouble pulling things out of like a 386 before. [laughing] so, yeah anyway, the
rest of this just seems to be generic. Ah, we’ve got a datasheet, how nice. Although I already looked
up all this stuff online, but yeah, check it out, man. This is something I’m
pretty excited about, 16K of code cache, and 16K of write back capable data cache. The AMD that I have in there right now is only 8k of L1 cache. Still no L2 on board, that is on the system board itself. I have 256k of L2 on that motherboard that we upgraded to in the past because didn’t have any L2
when we first did the build. But, yeah, this should be
quite the lovely thing. Ha, that is fresh. Look at this thing. That’s just so clean, so nice. And check out that integrated fan, heatsink cooler design, man,
it is all clipped on there. Looks like the fan could come off, but I mean that heatsink is
pretty thoroughly attached. And I like the fact that it looks like it gets the power
straight through the pins. There’s no connector for
a fan to the motherboard or Molex or anything like that. This is exciting man, ah dude, it’s not gonna be a 486 anymore, it’s gonna be the LGR Woodgrain Pentium, that’s weird, oh I don’t
know if I like that, I didn’t think about that. [laughing] Well, anyway, this seems like a pretty
clear upgrade on paper. Will it be 100+ percent
better like Intel claimed? There’s only one way to find out, that is get this thing set up and try out some benchmarks
and games and stuff. Alrighty. Let’s just get the old
AMD one out of there. Well, the new the CPU is old as well, but you know what I mean. There we go. Oh, poor AMD. Still a good CPU, maybe I’ll go back to it at some point, but not today! All right. And now our drop-in replacement. Okay, so I guess with socket three we don’t have exposed pins, unpopulated pins around the edges. I think that might just
be with socket two, you have like an extra
row all the way around each of the four sides. Okay. Well that’s that part out of the way, now it’s time to get to
everyone’s favorite part about old computers, all the jumper settings. So there’s quite a variety
of different things that this particular motherboard supports, but what we’re looking
for here is this P24T. I believe that is the Pentium Overdrive code name or whatever. All right, so JP9 should
be on one and two, it is. JP10 should be two and three. Okay, that is that one, now I gotta worry about all these. Okay, JP13 should be one and two, there’s nothing on JP13. So we will just add a jumper down there. [groans] There we go. JP23 needs to be on three, four, five, six, and seven, eight. [upbeat music] Okay, I think this is the last one. [laughing] All right, gonna triple quadruple
check everything here. According to my list and hey if everything checks
out we’ll plug everything in, power it on, see what happens. All right, everything’s
set up, ready to go, installed, whatever, we
just gotta get this on here and see what that’s about. But just power it on and see what happens. [computer whirring] Hm, sounds a little different. There is a CPU fan going. [laughing] Didn’t have one before this. Thankfully it’s not too loud or grinding or anything. Hey, check it out, so P24T, 80 megahertz,
close enough! [laughs] we’ll run a CPU check here in a second and see how that goes. All right, so yeah. Intel Pentium 83 Overdrive, 83 and a half megahertz, indeed. 2.5 clock multiplier,
bus speed 33 megahertz, everything looks as it should. Yeah, the internal cache is
probably not gonna do everything because I don’t believe I
have write through mode. So I may just have the
16 out of 32 possible K on the chip itself. It’s only gonna be write
through for the internal cache, which means we’re not
gonna get the full 32K. We have 16K of the cache on L1, L2 is write back, that’s cool. Not game-breaking, but worth noting, this motherboard isn’t
the most powerful thing to pair with a Pentium. All right, so let’s try
Top Bench, really quick. Because I want to. And also because when I ran it before, back when we installed the
external cache down there, 256K, we were getting around 190, actually it looked just like this here, ’cause that’s just what
this is. [chuckles] So, around 190 points you
can see in the top left there is just running in real time. So if you run the benchmark
in real time here, we should be, yes, it’s a bit faster, 218. So equivalent-ish of, well
it’s going back and forth, Pentium 75 clone or thereabouts. Let’s see what it is with turbo. Nice okay, so turbo still
cranks it down a good bit. Like a 386 DX40, not nearly as slow as it is with that 486, but we can disable the
external cache and other things if we really wanna get super slow, if we’re playing certain older games, but yeah, around 218, 219, not bad, not the biggest jump though. I was hoping to get around 240 or 50, but again this motherboard
just isn’t the best thing for the time. Still, an improvement nonetheless. I mean, it is working right? So here’s something else I’ve
got another benchmark on here this 3D benchmark. Let me show you what it was with the 486 that we had in here previously, this is more of a test of
VGA capabilities and whatnot, but you know should still
be faster with a Pentium, so with the 486 ended up
getting a score of 47.1 or run it with the Pentium here and see what we get. Should certainly be faster, I’m not expecting a ton faster, ’cause again, we need to
upgrade the video card and whatnot to make more
of an improvement to this, I believe. 55.7, okay. Just out of curiosity, I’m
gonna run cache check here and I’ll just have it check the cache. I’m curious about that L1, if there really is, just
getting a 16 of the 32. Oh, that’s the results. So, yeah only 16k of L1, but man that’s like two or
something times the speed, maybe three times, it is a lot faster than the 486 one was. Plus it’s got all sorts
of floating point stuff and Pentium things. It is a clear improvement so let’s just go ahead and
try this Overdrive processor demonstration and diagnostics disk. So there’s a Windows version. I don’t wanna do that. Ah, it’s got a fan
monitor, how cool is that, and DOS, I like it anyway. All right, install all the things please. Listen to the sound of my disk. [floppy drive noises] All right so we’ve got some demos, we got a fan monitor, let’s just see what that looks like. [laughing] It’s on. [laughing] No RPMs, no anything, it’s just “on.” Okay, let’s try this. The actual program itself! Mm, got a mouse. I don’t know what kind of
weird resolution this is it is bowing on my monitor and I don’t feel like fixing it. Let’s see if there’s any different. It’s the same thing! Just says whether or not the fan is on. Review installation demonstration. Whoa, [laughing] Oh, that’s so cool, man. The dithering! I am gonna capture this
on the capture device for posterity really quick, hold on. All right let’s start that over ’cause it’s worth it. Look how awesome that looks. I mean, I hope it looks good to you. Or else I’m just going crazy. Being a weird old man. [laughing] this, ah, I love these
kind of little things. Look at those hands. Dude. Animations. [laughing] Oh, those are phenomenal looking
pixels on the motherboard and there all the little details, dude, somebody put some
real, serious time into this. Intel, man, they didn’t hold out. Oh, look at that, look at the
little removal tool graphic. [laughing] Oh that is so cool, aw look at that. That’s enough of that, if you wanna see the rest of it, you can see the download
in the video description for the disk and take a look. Anyway, let’s run the
processor instruction test. Oh man, wow. I’m assuming that that is legit and it’s not just running numbers in an animation. [laughing] All right, that’s pretty cool. Floating point conformance test. Oh that’s my kind of test right there; I love conforming to floating points. Doing some math, just
calculating tons of things, man, the power of the Pentium. Look at it go. All right well that’s all for that. Didn’t really do a whole lot other than show me some
really cool animations and some numbers that I am going to trust that were real. Right, let’s run some games. I mean, we gotta try to do it 3D because it ran like
total crap before this. I mean, it’s probably still
gonna run like crap to a degree, but let’s make sure everything’s good. 320 by 200 normal mode, we’re not even gonna mess
with VASA compatibility. But if you’ll see the footage here of how it was running on the 486, that we had before this, this is just the first
level of the first episode. And you can see it hangs
around 10 frames per second just at the beginning. And it goes much lower down into the single digits and whatnot, throughout the rest of the level. And it’s not great. This is again, 320 by 200 and it’s just rolling along,
chugging through the game, it’s not a pleasant experience, mostly single digits. But now we’re gonna try it on the Pentium and man it’s already loading much quicker, so that’s good. [explosions]
Nice. [8-bit music] – Let’s rock. [game character speaking] [laughing] – Well, it is nominally better, we’re getting low teens up there. So that’s the frame rate
more or less right now. Ah, you know.
[gunshots] It’s faster but again, there’s only so much we’re
gonna be able to squeeze out of this system
considering the other things that are installed in there like the video card. It’s certainly more playable though, that’s for absolute sure. Not as good as I could
be, but I’ll take it. Time to die. If I were spending the
equivalent of 500 bucks on this back in the day for
games or whatever like this, this would not be the
most satisfying thing. There’s other bottlenecks that I think are making
much bigger of a difference in terms of games like Duke 3D. Let’s try Descent II. Because that’s another one that
just ran like total garbage on the 486, let me show you what that looked like, here’s some direct capture of Descent II on the 66 megahertz AMD CPU that I had in here before. And again, single digits. Low teens. A little better than Duke 3D, but yeah, not great. Even when cranking down the settings. This is the highest settings here, but if we crank the detail
all the way down to the lowest it’s you know a little better, you get a few extra frames here and there. I mean, I would have played
this when I was a kid. [laughing] It’s just such a cool game that I wouldn’t have cared. But, this is not great nowadays, that’s for sure. And low detail, mid-high detail, whatever, it’s all pretty sucky. So. [rhythmic music] moving over to the Pentium. Let us see how this goes. [upbeat music] Looks better. Let’s turn on the frame counter. So, okay yeah, I mean that’s, again, pretty clear improvement. Oh, much more playable. [lasers firing] Not great, still dipping into the
single digits here and there but not nearly as much. And again this on the
highest detail setting. [lasers firing]
So, that’s a red door, what am I shooting for? [lasers firing] Yeah, you know. [lasers firing]
[laughing] Can’t handle all the action. [lasers firing] Let’s see what it’s like
with the lowest again. [upbeat music]
[lasers firing] Nominally better, you know like it was in the 486, but, I mean honestly this is
about how I played Descent II for the first time back in the day. It was on a Pentium 90 I believe. So it was maybe a little
quicker than this, but… [laughing] Oddly nostalgic in a way. But just really the
whole point of this build is not to make the fastest
486 or early Pentium, just I’m experimenting with parts and seeing what things do. Because now I can. [laughing] It’s fun. All right one more thing
that I wanna try here and that is Quake because it didn’t work whatsoever, but we’re gonna try a benchmark. The venerable Phil’s
computer lab benchmark shout out to Phil for these handy programs and things you can
download on his website. So we’re gonna run the Quake time demo, just the normal one. And again, this did not
even run at all on the 486. I mean it tried. Well, this doesn’t either. Let’s try one of the other ones. Lower the resolution, I believe. Nope. Okay, a clean boot here, let’s see if it does anything different. Nope. That totally doesn’t wanna work. Let’s just try Doom, see if that does anything. Max details. [laughing] I didn’t run this on the 486, so I don’t really have
anything to compare it to, but certainly looks like
it’s running a bit smoother than it did on that CPU, just looking at it. All right. 2134 gametics. 2664 realtics. Those… are numbers. Again, I don’t have
anything to compare it to, unfortunately. Man, that sucks I couldn’t even get the Quake time demo to work at all, man. [Windows 3.1 Startup Sound]
[LGR humming along] So final thoughts on the
Pentium Overdrive Processor 83 megahertz, for now anyway. It’s unfortunate that it’s connected to such a computer! You know if it was a more capable machine, we would be getting more
of the capabilities of it. You know, it’s a weird conundrum. I was reading about that in the reviews, its contemporary reviews back in the day. People were like, just again, questioning who exactly
is this for because the faster your system
is the better it is, the newer it is, the better
capable your 486 board it, the more you’re gonna get out of this. The older it is, the less
you’re gonna get out of it, it’s like backwards. You know, the people with
the slower, older systems, don’t get as much out of the upgrade as the people with the
newer, faster systems that are already newer and faster, so… Yeah, I much rather have a
486-DX4/100, stick that in here, or maybe even one of
the AMD P75 or something you can overclock and do cool things. Maybe I’ll try that in the future. And I also do wanna
try with messing around with different VLB compatible cards, like some different video cards. And memory as well, I wanna try to maybe some faster memory, because I think that would make
a good difference, honestly. Got I think that’s a bit of a bottle neck. Anyway, all sorts of things
to mess with on this 486 and [laughing] that’s why I have it. It’s just, yeah, screwing
around with configurations and things that I never
could back in the day. Wondered about them. I’ve always been curious
if they’d been any good ever since diving back into the hobby as an adult and yeah it’s like, I don’t know it’s just fun. I love messing around with these things. [arcadey sound effects] And I love Missile Command. And my camera battery just died, so I guess that’s the end of the video. I mean, it pretty much was anyway, I was just wrapping up, so right, if you enjoyed seeing this then do checkout some of my others in the 486 updates, upgrades series or whatever else I post here each and every week on LGR. And as always, thank you
very much for watching!

  1. The results of this upgrade have cemented my resolve to upgrade, like, everything else now haha. Next will probably be the VLB video card, but I'm also planning to try some different RAM, as well as a DX4-100 from Intel since I have one of those already. And if nothing else, I also have a much nicer 486 mobo ready to go 😛

  2. Just sul what was the first bootable CD is used in computers I would like to know and I am from India do you know about knoppix a beautiful CD-ROM flavour of Linux which was the first one to be used as we were afraid of formatting our Windows hard drive episode on bootable CD history

  3. LGR sounded like you were doing the dukes voices once the Pentium was installed. That was funny had to go back to check… “time to die” lol 😂

  4. Oh MY! I remember those, fondly. In 1994/5 I was writing the code for a touch screen information kiosk system called Metrodata in Basic with a bunch of little machine code parts. I started out with an Intel 486/33, upgraded to a 486DX2/66 the finally to a "Pentium" 83 like yours. I don't know how much they would have helped the average user but for my graphics manipulation and programming they were the ducks guts. I really found out how much they helped when I had to write the graphics color 'normalizer' that took the high color BMP pictures for a page and normalized all of them to one 256 color pallet since that is all we had to work with. The pages were put together on a computer with one of these chips then exported to a file type I wrote that would load quickly on a 386 with 1 meg of ram. The difference in the time it took to bring in the various pictures for the screen and normalize them was something like 1/4 of the time it took the 486DX2/66. Ahh, memories of the good old days.

  5. Prices back then sound about right. When I purchased my first 320MB hard drive I paid $340 for it. I thought I wouldn't need a drive larger than that. =) Clint, love the sounds your system is making and I about had a nerdgasm when you put the mic up to the floppy drive! 😀 Great video!

  6. Duke Nukem 3d's Atomic Edition is much slower on my 486/100 than the three-episode one. And I mean the entire engine is, not just ep 4. Surprised the heck out of me back in the day.

  7. I used to play Duke3D on both a genuine Intel DX4/100Mhz and a Pentium 60, but it ran WAY faster than what I'm seeing here.. is this due to the motherboard/platform not being made for pentium?

  8. This is the thing I use to demonstrate to my friend of many years, who tends to get fixated on things that dont matter and arent what he needs, that he is again fixating on something that doesnt matter and wont do what he needs. Or only do it passably, as opposed to <something else> that will be much better, proabbly cost way less, etc. This is a behaviour of his since long before the Pentium OD, but this is the one that finally broke him back in the day. He built a system FOR one of these. I was like um what? You are going to source parts to build a DX2 system…. and then put a P-OD in it, when you could, for a tiny bit more money and FAR less hassle, just build a P75 or P90 by that time? wha?!?!?1

    So you know how that worked out, and to this day when he wants to invest way too much time/money into some PC snake oil, I just say "yo, hey no, thats a Pentium Overdrive right there." And it always works. 😀 (edit: DX2 not 4 lol)

  9. Dude, your Duke impression is awesome 🙂

    Btw. I was just wondering how ~12y old non-english speaking me in the early 90s understood all that computer tech with jumpers, dip switches, HDD h/s/c settings, config and autoexec, DOS (and CP/M before) in general etc. etc. without Google …all by myself. And almost 30y later I'm watching Youtube at 4 o'clock in the morning…

  10. Retro Heaven!
    I have just completed my Windows 98SE grey monster. A PII/333MHz fitted with my original Sound Blaster 64AWE, Voodoo 1, ET6000, MS Sidewinder 3D Pro joystick, Logitech Trackman Marble (from my old 200MHz P1 PC back in the day). But now it has a massive128MB RAM ! (The MB is an ASUS P2B, it will only take 128MB) But I ran W98 with only 16MB RAM and it was fast in 1997! Also, I have rescued a ton of Toshiba Satellites and a couple of IBM Thinkpad laptops from the scrap heap, because they won't even run Ubuntu 12.04.

  11. Intel was trying to price gouge the nickel dimer upgraders, fooling them into thinking that they were being wise and frugal. When AMD & Cyrix continually relased a fairer priced option, Intel abandoned the socket in favor of a patented Slot architecture, physically excluding competition from the market, since Intel couldn't rip away the x86 architecture rights from competeition. Although they did try that in court, relentlessly.

  12. Why did you skip the fan monitor feature? I think in 1995 wasn't exist any fan monitoring in pc's, so that an unique feature in the 90's. If i remember well.

  13. It really amazes me how much sealed boxed stuff you get. The best we can get around here is a 2013 Dell someone wants to sell for 2000.

  14. We used to play Descent/Descent II/Descent Freespace on the machines in my high school's computer lab around 98/99. Those machines were somewhere in the 200-233MHz range. Had no idea Descent of any flavor would even run on a 66MHz CPU at all.

  15. Clint, thanks for covering this because I have the same 486 DX2 66Mhz and I was wondering how to upgrade it. This is very helpful (I am nervis about changing Jumper setting) and really enjoy your show!

  16. What would be hilarious is if those charts in the documentation were made with Lotus 123 using a Pentium OD system.

  17. This guy would probably cry if he saw what I threw out last week. De junked the closet, threw out everything that was IDE, several creative 24-48-52x cd roms, several hdd's, few mobo's, few AGP video cards. Wads of ribbon cables. Few 96 or 98 era atx cases.Sound cards.PII 400. Got tired of it taking up all that space, wasnt worth my time trying to sell it.

  18. my 1st cpu upgrade was a 386 to AMD DX2-80, but I also maxed out the RAM from 1MB? to 16MB??? I bought the best upgradeable board and case, for the money I could spend. plan was to slowly upgrade from a cheap expandable system to highest end+ available over time.

  19. I seem to recall that Intel got into some trouble where these speed claims were concerned, leading to a class action lawsuit or two. I put a Pentium OverDrive in my formerly-486 box- which provided a noticeable but not significant speed boost as you've noted here- and ended up qualifying for a miniscule refund of one sort or another.

  20. It's INSANE how little memory these chips had. (Am i saying that right)
    The THUMB NAIL on this video has more data in it!

  21. I don't mind when old games like Duke 3D slow down to single-digit frame rates, because like you said, that's what it was like man. Most of us didn't have the newest and fastest machines so that was just a thing. It's nice to be able to play old games all fast and smooth now, but I'm amused now to think back and remember playing Doom as a kid back in like 1994. When the screen would fill with monsters and the frame rate would start to drop, in a way it kinda made it scarier, haha.

  22. I remember Descent running much faster than this on my friend's DX2 66mhz. Probably due to the video card and VESA local bus?

    Meanwhile at home I had a Magnavox 386 DX 33mhz with 6 megs of ram. Doom ran okish at low detail and screen size reduced a tad (but not the smallest setting), it ran similar to how Duke 3D ran on the system in the above video except not full screen. Descent ran terrible. Single frame per second bad. Eventually I got a Packard Bell Pentium 166mhz which was far better. And then many more systems thereafter which I built because my friends kept calling my Packard a "tinker bell"hnnnnnnn

  23. I have considered building a 486 just to add one of these Overdrive CPUs, so I could see what kind of performance busy I would have gotten back in the day, over my DX4-100. Maybe even try compare to the 486 120/133Mhz CPUs from Cyrix(?).

  24. I always wanted to try Diablo with one of these vs my Cyrix 486 DX4 66Mhz vs one of these to see if it would run with Windows 95… just to see how Diablo would run.

  25. Not sure what the bottleneck is on the system. I got Quake running OK on my 486 DX4-100 with 16MB fast page mode RAM, and just 512k VRAM in the inbuilt Cirrus Logic video card. Full screen at 320×240. It was slow, admittedly

  26. Imagine intel offering an "overdrive" Coffee Lake processor to run on Sandy, Ivy and Haswell boards. Unthinkable today!

  27. Finally. After going through every single LGR video I caught up and can now wait for weekly episodes! Thanks for the content Clint, you're my new favorite content creator!

  28. I got one of these overdrive processors in the mid-90s for my 486 sx 33. It was a way to upgrade my computer without buying a new one. I seem to recall that the desktop cost around $1,500 brand new. It was a gift from my parents. I used it all through high school. But gaming was getting a little tough and I wanted some extra processing power, so I went to the store after saving up for a while I bought a dx 100. It worked effectively and the cost of the upgrade was a drop in the bucket compared to buying a new machine. And after I graduated and got a Pentium machine for college, I gave my old rig to my dad who used it for another three or four years.

  29. Any point in running UniVBE? https://dosdriver.de/graph.php

    I remember, long, long, LONG time ago, we had to run this one to gain a bit of speed on DOS games. Probably 'cos of some crappy VGA cards we had, but… Might even help you out with Quake test.

  30. Kids today will never know the excitement and thrill of the dance of death, otherwise known as the Jumper Jive.
    "See kids, back in the day, if you moved these plastic-wrapped pieces of metal onto the wrong pins, your system could respond in a whole host of ways. Could simply not work, or could go up in a puff of smoke, like a hamster in a microwave. And we had them on everything…Motherboard, hard drive, optical drive, modems…You name it, we had to have jumpers on 'em."

  31. All this time I thought the Overdrive somehow fitted over your existing CPU. This is way less cool than what my 10 year old self envisioned.

  32. Thanks for the nostalgic memory, Clint! I actually had one of these back in 1995. I don't think I paid full retail, but it wasn't cheap. That said, this Overdrive upgrade was appropriate for me – a college student that couldn't afford an entirely new system but had a 486/DX2-66 system that was lagging a bit (especially after Win 95 was installed). In years prior, I had already upgraded the RAM(48MB!), CDROM (10X?!!) and HDD (850MB!), so a significant bump in CPU performance that could be done in minutes looked really attractive. I already had a decent VLB video card with upgraded RAM (by adding individual ICs to bring it up to a whopping 2MB) so after this upgrade my PC was mostly on-par with my roommate's newer P75 PCI-bus system and could actually take it in some benchmarks/games even with a bus speed deficit. I ended up getting another 3 years of life out of the machine – so all in all it was worthwhile for me even though it definitely did not have mass appeal for the reasons you mentioned.

  33. I hope it wasnt just me who went and downloaded dos benchmark to see how my pc stacks up against the beast that is the 486?

  34. When I look at this, I miss the old times in many ways. The weird quirky parts, datasheets. reports and lots of fun tech for enthusiasts.

  35. Weird I came across this video because , just last night I was looking at a DX4 over drive Still in the Box and in the corner it says "Upgrade to 100 MHZ" 08-21-96 O_O WOW, now I can play my all time favorite game "Castle of the Winds"
