LGR 486 Update! 83MHz Pentium Overdrive CPU 

"This seems like a pretty clear upgrade on paper" he says as he puts the CPU on the paper manual :P

Fancy fan monitor in the mid-90s: "it's on"

Please fill out the "stay in loop" registration card and send it to intel. I'm curious about their reaction :-D

A friend of mine had one of these. It seemed to mostly work!

The weird time when Intel and AMD could run on the same board.

I was building PCs during this era... These never worked as expected. Massive compatibility issues and pc hardware prices were dropping so fast that most people just bought new computers.

13:10 Clint got that Big Disk energy.

10:14 *HOLD ON* mouse support in a 1993 BIOS? WHAT?

Hey man! Love the work, my computer science teacher literally makes me watch you as our homework 😂

It was a time when we counted in HALF megahertz. Now we're grossly rounding CPU speed at half GIGAHERTZ.

9:00 oh man, I do NOT miss jumper settings.

Activate Duke Nukem voice “Listen to the sound of my DISK....” Damn LGR, just damn...

Clint: _"[...] and I love Missile Command."_ Camera: _"Not this again...!"_ *[kills itself]*

I remember when Pentium 4 was launched back in early 2000s and required a separate 12V cable as Pentium 2s and 3s were 5V only. Anandtech called its cute little CPU cooler (by modern standards) a quote/unquote "Mount Everest". It's fun digging through the archives!

Imagine a world where you receive paper manuals and an Intel-branded installation tool for an 83 MHz CPU. Damn I miss the 90s.

I appreciate your love for this old tech and I can hear in your voice the same excitement that I hold when setting up old stuff from my childhood. My favorite channel!

I remember when my dad brought home a Kingston Technologies 120MHz overdrive chip and put it in our computer... :) This brings back memories, lol

They must have included the "floating point conformance test" after the whole Pentium FDIV debacle :D

This takes me back. I feel so old right now. It's amazing how far tech has come.

The biggest advantage I think with some of these was that if I remember correctly, the Pentium chips came with float-point math, whereas the x86 chips did not (and required a math co-processing unit). That and back then if you had a 33 MHz system, going to 83 MHz was more than double the speed. Even less if you had the 66 Mhz version, but still 17 MHz back then was about a 20% speed bump over the faster 66 Mhz 486 at stock speeds.

"No bachman turner" - you're old for saying it, I'm old for laughing at it ;)

I can remember being in my first IT support job in London, England fitting those to Compaq desktops in Investment banks. They did make a difference to their spreadsheet work.

This is why I still tune in after all these years. You still find amazing little gems that bring me way back. That damn packaging dude!

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.

Ahhh, simpler times, when you did not need a fist sized lump of aluminium and copper to cool your CPU.

When your mum thinks you're watching a video from the 90s cause she hears a guy talking about a computer she knows about...

This has been one of my favorite videos! I always wanted to do this back in the day, it was always to expensive. Thank you for letting me live it through you!

Man! The banners that I could have made in print shop with that thing!

As a nerd from the 90s , I'm always watching these videos so much. Keep up the good work Clint

Oh the good old days of messing about with jumpers, and by the time you had set them all correctly a faster CPU had come out and you had to start over....

So many memories of the 486 era and working on my own PC. Thanks for putting these out!

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! :D Great video!

This brings back so many GOOD memories :D I remember having a 83MHz Pentium Overdrive and it was the best CPU for 486 systems that fully support the processor (allowing the internal L1 cache to run with write-back mode enabled and without any interposers that disable the L2 cache). A bare handful of POD-83's also could take an "overclock" to 100 MHz (40 MHz bus), but it wasn't too common. At 100 MHz with write-back L1 cache, it obscenely massacres all the other Socket 2/3 contenders, unless they're clocked to ridiculous (and usually unattainable on most motherboards) levels. I've got a Genoa TurboExpress 486VLG-2X motherboard with SiS 471 chipset and S3 805 VLB video card, running an 80 MHz (40 MHz bus) clocked IBM 5x86 in an Evergreen 3V adapter at the moment. With this processor/clockspeed setup, DOOM runs at close to the same realtics as it does with 100 MHz core / 33 MHz bus, showing the rather profound effect that the higher bus speed has on final performance. (Setting the ISA bus to run at 10/12 MHz saves a lot of realtics when sound is enabled, just remember that most ISA cards don't like running past 10 MHz). Awesome review Sir!

I used to have one of these. :-) If I remember correctly back in the day, there was a lot of talk about how a DX4/100 was faster than the slower Pentiums

Another awesome upgrade video Clint! Really refreshing and nostalgic seeing computers of yesteryear being upgraded - anyway, looking forward to the next one bro'! More power and God bless from the Philippines!

"No Bachmann Turner included" just made my day. Thank you

This was my first desktop that was all my own! In a Packard Bell! Ran it until 2003 even running Windows 2000 painfully on 32mb of ram.

Last time I was this early, I pressed the turbo button. 💥

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!

I just wanted to say that this is the rare channel where I like the subject matter and I also totally connect with the presentation. I started viewing videos on pieces of hardware that interested me, and I ended watching most or all of them.

Fascinating! I had a i486 dx4-100 back in the day, can't remember which revision... such nostalgia! much processor! :D

Lol "No Bachman Turner included" :D

"The beginning of a valuable relationship with Intel. Just what I've been looking for around Valentines Day" Heehhehhee, priceless 😂😂😂

Thank you for continuing to find things I didn't realize I had nostalgia for. Really enjoyed this video. It's crazy to look back at how much of my life was working with PC's, helping friends and family decide on upgrades and the "joy" of troubleshooting. I actually did a processor upgrade to an Intel DX4-100, man I thought I was hot shit then. 100Mhz! I'm unstoppable!!

2.38W -> 14.7W oh Intel :P

I want someone to sample you saying "listen to the sound of my disk" I feel like it would fit really well in the beginning of some sort of remix/ techno music

You got a cool shout out from Linus! Good stuff to see all of my guys acknowledging each other!

Oh the memories of my 8th grade PC are flooding back to me! When I got into high school, there was a computer store very close by so I had my dad swing by on the way home so I could see how much I needed to save. I was looking at all the shiny new Socket 7 and Socket A stuff but they were way out of the budget for at least a few months. Instead, the guy behind the counter said, how much money you got kid? I was like...$20? The sales guy said, hold on, I think I've got something you'll like! A minute later, he brings me a dusty chip and says "it's no Athlon, but for $20 I can almost double your speed with this chip." A short discussion about my mobo later we determined that I was running Socket 3 and was good to go. The jumper settings were printed right on the board. No joke, it is to this day the best $20 computer part I've ever bought. No other part under $100 has brought me such joy. It not only made Duke3D run WAY better, it *enabled* me to play other things, albeit just barely. I was lucky enough to have a pretty quick VLB VGA card so later DOS games got almost smooth with this chip. (Quake was a slide show and had to wait until I got my Socket 7 box later that year) Technical info.... The extra row of pins is present on on all PODP sockets, Socket 2, 3 and 6. These are the reserved pins for the PODP that are visible when a 486 is installed. These sockets differ primarily in the voltage support, with socket 3 being the most common and most versatile. Socket 2 does 5V, Socket 3 does 5V and 3.3V and Socket 6, the rarest of the three, supports 3.3V CPUs only. All PODPs are 3.3V internally; the 5V ones just have a built in voltage regulator. (the circuitry visible under the heatsink) Some systems require an interposer that lifts one pin on the PODP chip to work around some chipset bugs involving cache. Remove this if present and see if the machine remains stable as this workaround disables the L2 cache. This interposer is the "extra hardware" that Packard Bell 450 needed to use the PODP. Performance of the CPU is much better than a 486 and slightly better than a Pentium 60 but slower than a Pentium 75 as the FSB is a serious bottleneck on PODP systems due to the use of the 486 bus. The bus not only runs at less than half speed, but it's half as wide as well. The L1 caches are larger on the PODP (32K total) than in the plain Pentium (16K) to compensate for the lack of FSB bandwidth. Did we skip sockets 4 and 5? Nope! Socket 4 is for the original Pentium (60/66MHz) and Socket 5 is for the 75+MHz 3.3/3.52V Pentium. Socket 7 is essentially Socket 5 with split core and I/O voltage though the earliest S7 boards sometimes didn't implement the split voltage, making them unsuitable for non-OverDrive Pentium MMX CPUs. Super 7 is Socket 7 with a 100MHz FSB and low core voltage support for the K6-2 and K6-III CPUs. Socket 8 is for the Pentium Pro, the predecessor to the Pentium II and basically all "modern" x86 CPUs.

I LOVE that you reviewed this chip. I totally remember it back in the day and complained about how expensive it was. Now that I see it would've done very little for the price. I feel better now that I never got it.

I got one of these back in the day when they started getting cleared out on discount. Definitely breathed some life into my 486 and got me by for another couple years.

Hi just to say I've been watching you're videos for a good long while almost watched all of them but this one is the best one I've seen keep it up I look forward to watching more

Always love to see you geeking out over this stuff! Thanks for the awesome content!

That processor-removal tool seems like an excellent way to end up with bent pins.

Always nice to see an LGR video when I have a nice hot cup of joe in the morning. Great video Clint, love these 486 Upgrade videos

I really enjoy your videos. It's like you verbalize the things I would be curious about, in addition to trying a few things I had no idea existed but still find fun to watch. Thanks LGR.

I purchased this for my IBM DX2-33 when it came out back in 1995! I remember I had to work all summer to save enough money for that thing! It also required me to do a EEPROM upgrade. I enjoyed the hell out of it. There was definitely a noticeable difference in performance. It was euphoric turning it on for the first time after the upgrade. I miss that wonderful machine.

Your Duke impression is so awesome goosebumps!

Ooohh.. you have the disk. Just expanded the description and see you uploaded it to archive.org. Thanks!

I've just discovered your channel. I'm a bit older than you, but I got into computers relatively later in my life (I'd had no interest in games up till about 1994 when I saw someone playing Doom, so then I was hooked and I just _had_ to have a computer! :) ), so I recognize the glee with which you're exploring these options that were unavailable or prohibitively expensive in their day, and the fun you have revisiting these old things. I remember, when computers were new and mysterious to me, I'd take everything as some sort of holy ritual - read the manuals, smell all the things, install every stupid bit of bloatware and gawp at the crappy little games that were included - e.g. I remember playing the heck out of the silly bumper car game that came included with Win95 (or was it 98?). It was all so exciting and new at the time - the glamour fades as one knows more, but it all seemed so magical when I was new to it, when the world was new to it. A lot of your vids remind me of the feeling I had the first time I went noclip in Doom and explored the strange non-world outside the map. All this old tech, with the faint echoes of the buzz and marketing and gimmicks that surrounded it, is a bit like that now - a kind of surreal _demi-monde,_ suspended in the void, that's nevertheless extremely charming and nostalgic if you lived through it at the time. Oh and a request: do a vid on the Rendition Verite graphics chips (made into a few cards like the Diamond Stealth 220, which I had). For a short while, these GPUs really fit a niche if you were building a new computer at the time, as it was a highly affordable full 2-d/3-d card. It was a tad slower than the Voodoo (although it was just as fast when using its own RRedline API - and the Quake people made a special version of Quake using it, vQuake, which could play Quake smoothly in higher resolutions, even with anti-aliasing, etc.). It's one of those "what if" scenarios - GPUs could have gone down the programmable route early on with these GPUs, but unfortunately the design was flawed in a way that meant that 3dfx, ATI and Nvidia pushed ahead in terms of speed at a crucial time. If RV had just managed to hang on, their next v3 iteration would probably have beaten all comers, but it wasn't to be.

I don’t know what any of this means. I just like to listen to your voice when I’m stressed 😂

Love to see a 286 to 486 chip upgrade I remember longing for one of those to do a quick upgrade

I'm the IT manager for my Radio Shack store, and this sure looks great. Boy these computers just blow me away with this kind of stuff. Those guys at Intel are just insane! They'll always be on top with tech like this. I can't wait to install it and run Quicken so much faster. Though lately I've been playing a lot more solitaire than anything else around the store, not many customers. The customers we do get tend to just hang around staring at walls or urinating against them. Weird.

Thanks for this unboxing video! I had an i486dx 33 growing up and my parents took the plunge and got this overdrive chip! This took me back:)

lol the blessing of them jumpersettings xD yups they sure did take some time to get setup right

Had one of those, it was how one sneaked in a upgrade when the wife didnt agree on a all new pc 🤭

I love such LGR series !!! It was very interesting to see such a modification !!! I will look forward to the video about 486-100 and especially about AMD K-5 !!! Thanks! =)

I love the fact that you watched the installation instructional demo AFTER installing it. I have done things like that so many times in the past.

"Listen to the sound of my disk"... love the sound of floppy drives, love the speed of SSDs.

This CPU was available for sale at Mushkin as late as 1999. I remember pricing it there to upgrade some old 486 systems, but I ended up going with the Kingston Turbochip 133 (AMD 5x86-P75 on an adapter), because some of the systems only had the original 486 socket. It was faster than the PODP5V83 anyway, except in floating point, but it wasn't cheap. They were going for $189 at the CompUSA in Raleigh late in 1998. If you had a state-of-the-art 486 board, you were actually better off with the Cyrix 5x86-100 anyway. That was a Cyrix 6x86 cut down to fit on a 486 board, and if you had Linear Burst in the BIOS, it would beat either Intel's PODP or AMD's 5x86. Problem was, it would only work well on the best boards. I usually recommended the AMD part, because it was just a regular 486 with WB cache and could work fine on anything.

I had this back in the day in my Presario 924cds. Still have it all except the disk. Thank you so much for posting it!

Strange thing for me to say, but I love those giddy giggles you let out. Really shows your passion for your work.

No Bachman-Turner with that overdrive? Let it ride, man.

"Listen to the sound of my DISK" (͠≖ ͜ʖ͠≖) 13:10

I was a 80's baby and because I was big into tech I received a lot of hand me downs. Every time I watch one of your videos I get major flashbacks/ptsd. Love your content!

Hi - Loving your videos - and the great 4K Res.! Thanks!! IF I may, a LOT of what you are Posting brings back Memories of what I worked thru many years back. While I was never much of a gamer, I DID stumble across a DOS Game which (seriously) deserves your attention. In DOS, but since the Win-3.1.1-Days, the "Crusader - No Remorse" and the newer "Crusader - No Regrets" games from E.A. (Electronic Arts - if I remember correctly?) was a HUGE step forward, and for me was HUGELY Addictive! Please search this out - but I would be happy to send you an 'Evaluation Copy'... Good on You for keeping Alive, the precious PAST of our Tech.! Cheers! Bernie - Vancouver, Canada.

I remember watching a review on another OverDrive processor, it's overdrive to Pentium2, but for Socket 8 motherboard, user can instantly upgrade from original Pentium Pro CPU to Pentium2, with MMX support.

the leap of speeds between 486 and the first pentiums has been really the most remarkable. It doesn't happens anymore that your next computer is 4X time faster than the old one

I really enjoy your videos! I really wish i would of kept more stuff from qhen i was a kid, my father owned a pc repair and sales company here in australia similar to the one you got to visit We had so much new old stock for years and it was sad to see 90% of it go, your videos are a comforting reminder of when times were so much simpler :) Thanks

Fantastic! I’ve always dreamed of performing this upgrade, but I. Ever got around to it. I’m glad you catalogued what I would have done :P

7:02 I believe the "LGR Woodgrain Overdrive" would sound more tasteful...

It is surprising how well the package has held up or being so old.

Thanks for directly capturing the demo graphics. I love them.

Thanks for sharing. I’ve always wondered about this.

LGR is in the top 1% of RU-vid for content, production and coolness! 😁 IMHO

I remember working in the CompUSA tech shop around this time and I remember a lot of conflicts with branded systems of that time. Crap shoot whether it would work or not.....lots of returns too.

I was eagerly awaiting this video! I've tried explaining the Overdrive to a few of my friends (anyone who will listen) and no one could remember it. I convinced my dad that we needed one for our 486/33 box, that way he could run his 3D CAD software faster. Really, it was because I wanted to play better games.

This was the platonic ideal of an LGR video. Thanks for making it!

LGR: "The Intel overdrive doesn't come with Bachman and Turner." Intel: "You ain't seen nothing yet."

Could you imagine going back in time to 1995 and dropping off today's most powerful system?

i always wondered what that overdrive was all about. thanks for showing us

God I love your videos. I feel like I am on the 90s when all things are simple.

"Listen to the sound of my disc." I spat out my coffee! Good stuff! Thanks for more fun nostalgia!

Oh my god, that installation slideshow is SO FREAKIN' 1997! IT MAKES ME FEEL LIKE I'M BACK ON GEOCITIES!

Man, you are the very definition of a flashback!!! Awesome video...

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!

3:32 Presumably this was an "we have this old server that's been sitting in the backend someplace, and it'd be nice if we could give it a bit of a boost without needing to replace the whole machine" sort of upgrade.

4:27 Fill it out lol and mail it to Intel.

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.
