Tomb Raider (1996) on the fastest 486 CPU (Part 4)

Great job straightening those pins! They were really in bad shape. So much effort to bring this CPU back to life.

Thank you! I am happy that I could save this CPU, even if it took a lot of time.

I used to fix those using empty 0.5 and 0.7 mechanical pencils. You insert the pin in the metallic tube at the tip, which gives you excellent control on where you apply the bend force along the pin.

[@Choralone422]

Excellent work! Back in those days I ended up having to run my AM5x86 CPU at 120MHz (40MHz x3) as I could not force a 2x or 4x multiplier in the 486 mainboard I had at the time. I remember trying to play Tomb Raider on that machine and it was not very enjoyable and downright unplayable in places. However, any game that used the Doom engine or similar 2.5D FPS game engine all were a great time! To get decent performance in SVGA software mode in Tomb Raider you needed a Pentium 166MHz or even a 200MHz. Examples like that are one big reason why 3D accelerators like the original 3dfx Voodoo cards were such a huge deal. It made games like Tomb Raider that were mostly playable in VGA mode on a Pentium PC and allow you to run them in SVGA 640x480 resolution at a smooth (for the time) 30 FPS or higher and allowed for 16bit (65K) color modes instead of 8bit (256) in DOS as well!

[@SaraMorgan-ym6ue]

this is the kind of work to make you go crazy making bent pins straight if you are not carful to take precautions.

[@lucasrem]

Choralone422 The MMX 120 was released just after the Voodoo driver for Tomb Raider, needed that faster MMX 120 Pentium for it. Was on pentium 60, needing better build.

I admire your precision and patience to rescue a CPU in this condition. How much time did it take you to fix all pins? Thanks for your videos. Always a wonderful throwback to the past.

[@bitsundbolts]

I fixed this CPU back in December :) but I remember spending a whole afternoon on the pins, soldering, and refinement. I must have spent three to four hour on this CPU.

[@retroanderson]

At this point I think you should build a tiny hollow pin straightening tube/pen. Great effort, I had a box of CPU's in similar condition and it was not fun, the old socket thing is a good trick though!

[@bitsundbolts]

That would be a good idea to build something like this. Although I am done for now, there is a box with socket 7 CPUs waiting :) Such a tool could reduce the time immensely because many pins would probably take a fraction of the time when using such a tube with perfect properties for a specific socket. The more difficult pins can still be fixed manually. I'll think of something.

[@mladenp84]

​@@bitsundbolts Maybe something like soldering needles? I'm using them to straighten legs of TH components when desoldering. Pack of 8 different sizes is ~2€ on AliExpress.

[@Stefan_Kawalec]

@@bitsundbolts I saw pictures of someone using Pentel Graphgear 1000 automatic pencil for AMD pins. That straightening tool should be made as pliers with inner diameter slightly smaller than the pin diameter, so you could also straighten the twisted pins. By simply closing the pliers, you'd squeeze and straighten the twist. Probably buying some bend or straight smooth jaw long nose pliers and then machining them to specs would be the best idea. You could easily punch the channel for pins on the surface of those smooth jaws.

Erst liken, dann ansehen. Absolut erstaunlich wie viel Zeit und Sorgfalt in deine Arbeit reingeht und man danach mit einer funktionierenden CPU belohnt wird. Ich kann auch bestätigen, dass der ADZ bei FSB33 vom Speichersubsystem gebremst wird. Ein ADZ mit 3*40 ist ähnlich schnell wie ein ADZ mit 4*33. Du könntest mal prüfen wie ein Ur Pentium reagiert wenn man mit 2*50MHz oder 1,5*66MHz arbeitet.

[@bitsundbolts]

Ich werde 3*50 und 4*50 (mit höherer Spannung) versuchen. Mal sehen ob's klappt. Leider kann das Soyo Board nur mit FPM Speicher. Mal sehen ob ich ein anderes Board mit EDO Support habe. Ich habe einen Ur Pentium 75 für Sockel 5. Vielleicht mal was für ein zukünftiges Video! Vielen Dank für's Video schauen!

[@GigAHerZ64]

It is just so beautiful to see your work on straightening the pins... And woah!? ADZ with write back L1? I thought only ADW (of those 3-letter variants) can do that... NB! 3x50 might give better results than 4x40, as with higher FSB the memory access and L2 cache access becomes faster, too. When using VLB videocard, it helps that too. Maybe worth to try?

[@bitsundbolts]

You are absolutely right. I tested 150 MHz as well, however, in SpeedSys, 160 gave better results. I will test this once we get the Voodoo in there. I also want to try 200 MHz. At 3.45V, the CPU doesn't boot. Maybe I can try my luck at 4V.

[@GigAHerZ64]

@@bitsundbolts yeah, speedsys and other such small benchmarks usually do some small loop test or something similar. And when that test code can (mostly) fit in L1 cache, then the bus speed doesn't matter. But with "bigger" tests (for ex. Doom run) the bus will be heavily used and difference may start to appear. ;)

[@bitsundbolts]

I want to change the motherboard later in a "tuning" video because the Soyo only works with FPM memory. I did see a big improvement in memory bandwidth when running at 50 and even 40 MHz bus speed. I agree that a proper test using some games will be much better than those synthetic benchmarks. More videos to make :)

[@xrror]

@@bitsundboltsI was about to ask if you were going to try 50x4, so heck yea. Actually had a few 5x86's back in the day and we ran them all at 160 - and assumed they all would. Based on what I've read nowadays we just got stupid lucky with the ones we had apparently! That said we never got 200mhz to work, but we also didn't have any boards that would officially do 4v, and I imagine we'd have been too chicken to try it even if they did!

[@bitsundbolts]

Hehe, what's the worst that can happen at 4V - the CPU dies. Oh well, content is made and the videos are online. I really hope that the CPU can do 200, that would be nice!

Called it! Deliberately broken off ones don't count. 😄 Joke aside, awesome job once again! Performance is right where I expected it to be. You should be able to overclock the Cyrix CPU by 20% as well. Which one is faster probably comes down to which one overclocks higher, as they are so evenly matched at their default frequencies. May still end up being a draw! Going from software rendering to Glide was/is such a milestone, thanks for including the teaser at the end. After almost 30 freaking years, it STILL makes the difference between something I would and would not enjoy playing. For some reason, I particularly like the output early 3dfx cards produce. It took me years to get used to the "crisper" look of later cards.

[@bitsundbolts]

I'm also looking forward to getting rendered in glide mode. I'll include overclocking for the Cyrix and AMD CPUs in the 3dfx video. I already started to work on the card.

Just awesome! The bending adventure is real. I'd really liked the detailed review of this CPU incl. overclocking.

Looking forward for the next VooDoo Repair; it looks really bad! Wonder what people do with their hardware? Use it as a door stopper!? Thank you for saving all this hardware!

[@bitsundbolts]

To my knowledge, Intel designed socket 3 with future CPUs in mind. The only CPU I know of that uses the outer rows, is the Pentium OverDrive. I'll have a second video about this CPU soon once I get the fan. The outer row is mainly ground and power pins.

I'll add 3x50 in the benchmark video when I add the Voodoo card (after I fix it). My CPU does 150 at stock voltage as well. I'll also attempt 200 MHz, but I have to increase the voltage.

[@jasonknight1085]

If your mobo will provide 50mhz FSB, the 3x multiplier for 150mhz runs faster than the 40x4 setting because it's just able to shove memory around faster. You end up roughly equal in most titles to a P90. It was my understanding the reason they didn't sell them as 150 or 160 is that the majority of 486 motherboards only supported 25 and 33mhz. The 40mhz was common, but true 50mhz boards (and the true 50mhz 486's) were rare. But if your board supports it, 50x3 for 150mhz is the peak performance mark. A LOT of the x4's get choked / throttled by the bus not being able to feed it fast enough.

I'm pretty sure the ADW version of this CPU was the one I got for the very first computer upgrade that I bought myself. It was a good upgrade from the 66MHz 486 that I had before, but it wasn't as much of an upgrade that I hoped. If I'd known it might have been a simple matter of bumping up the FSB to 40MHz, I definitely would've tried it and enjoyed the speed boost for a little longer before I upgraded. I think I got the am5x86 sometime in 1996, and I'm pretty sure it took me over a year to save up for its replacement. Even second hand, a Pentium MMX 166MHz was pretty expensive for a high school kid with no job. But if I'd waited a few months, I would've found I could buy a Pentium Pro 180MHz for about the same price as the Pentium MMX, and overclock it to 200MHz with no issues. I did end up doing that probably about 6 months later, because the guy who was selling that Pentium Pro board and CPU kept bringing it back to the computer market every month and dropping the price until it was stupid not to buy it (I think I paid like $60 Aussie dollary doos for it). Anyway, great to see another scrap CPU fixed and working! It was very stressful watching you bend those pins back, I thought for sure one was going to break! But when you said those pins couldn't be straightened, it was somehow a relief that you decided to break them off and solder replacements on. But congratulations on a job well done, I'm sure it was very satisfying when it booted for the first time!

[@bitsundbolts]

I can fully relate to your 486 experience. I had an AMD 486 DX4-100. I remember how scared I was overclocking it to 120 MHz. I found out because I went through the motherboard manual. But I reverted the overclock a few hours later because I was scared of damaging the CPU. And I couldn't feel much of a difference during the time it was overclocked. I have two Pentium Pros (180/256, 200/512), but no board yet. Those CPUs are massive! Back then, I never paid much attention to them. That beep during the first boot was definitely a relief! Would have been sad if the CPU wouldn't work after all this work.

[@tony359]

usual stellar job in fixing those pins and nice CPU running at 160MHz! About the heat, my understanding is that it would allow you to bend the pins while keeping the structure of the metal intact. Doing it at room temperature won't be more difficult but the metal might weaken more. in other words: you won't see a difference but heat should make the process more reliable. That said: using the broken socket to finish the CPU off is definitely a cheat ;) Thanks for the video!

Only other software mode I would have liked to see is 50x3, as this is what I settled on back in the day. It consistently pumped out more fps than 40x4 in Doom and Quake on my setup. I know it's difficult to find tolerant video cards for this fsb speed though.

[@typedrat]

I've always thought it should be called the DX8, because clearly the multiplier is the log2 of the DX number plus one.

[@Beus38]

No, it isn't :) I have read somewhere that it was basically just a market name thing. It went like this: when Intel originally invented the thing called multiplier, they came up with multiplier of 2. So they marked it DX2. But for future, they wanted more granularity, so they planned to use halves, not only integer numbers, just like they were being used for many years to come in Pentium 1/2/3/n lineup :) So the next multiplier was planned to be 2.5, for which a market name DX3 was planned. But the processors with this multuplier were never released. However, it was already decided, so when multiplier of 3 came out, the processors were marked DX4. Thus, AMD did the next best thing they could when adding a new feature to an already abandoned (by Intel) platform, and marked the multiplier of 4 as X5 :) At least, this is what I heard on how these strange DX numbers arose.

If you want to go wild: Try a 60MHz bus by soldering a line from the S2 pin on the clock chip to ground (or S0 from memory, it's the one who's not connected to any of the two jumpers). I've done that and gotten the board to boot with a 5x86 at 3x60 . The clock chip and the board is capable of doing it, it's just not connected since the VLB bus might start glitching, but if you do not use it ... My "record" on this motherboard booting and running doom is 150mhz (3x50), but yours looks in a way better state than mine. Actually ... mine died and two address lines have leakage current comming from somewhere glitching them.

Maybe you're talking about the Overdrive CPUs. They were created to work in older motherboards that only supported 5 volts and therefore were incompatible to newer CPUs that required 3.3 volts.

I was already on the Intel 200mmx, iirc, and Matrox graphics.... played TR with the Matrox and a 3dfx... it was super smooth.

[@grayich]

To align the legs, it is most convenient to use a syringe needle with the tip cut off

[@Slamraptor]

Impressive OC and funny that it even gets a higher P Rating with it. xD

[@spavatch]

Ooops, sorry about the burnt work board 🤭 EDIT: by the way, going through my computer parts boxes I stumbled across something called IBM Blue Lightning 486/66. No clue where did it come from (I never owned a 486 system) and I have no idea what is it worth in terms of performance.

[@bitsundbolts]

Haha :) all good - I tried to get the pin off like I did on a PIII. That clearly didn't work.

[@ugzz]

Very awesome video! What is the tool used at 6:43 and what is it doing? It looks like maybe an abrasive the way it's making debris around it?

[@bitsundbolts]

Thank you! The tool is an engraving pen. I use it for all kinds of small work such as removing solder mask from traces and drilling into 3Dfx chips when one of the legs has broken off. I'll use it in the next video too because the Diamond Monster 3D misses one of its TMU pins.

[@ugzz]

Oh I actually wouldn't have guessed that! I had guessed an abrasive pen or scratch brush or something. Engraving would give you more precision and has alternate heads.. very interesting! Thanks for the reply, and Love the videos!@@bitsundbolts

[@Dungeonseeker1uk]

There's actually a tool used in Watchmaking called a Pin Vice that would be amazing at getting the pins straight once you have the standing upright, I'm 99% sure its pretty inexpensive too.

[@bitsundbolts]

Interesting. I'll check if I find what you're mentioning. I have so many socket 7 CPUs that need to be fixed.

[@ronwilgenbusch1961]

I’ve used a red plastic tube from a can of wd40 to straighten pins, and also a hollow metal hypodermic needle. Just use finesse. I can also verify I had a ADZ version of this chip from new in 96, and used an interposer for freq/voltage and was clocked for 160mhz, 40mhz bus with no issues. Was on a shuttle 486 motherboard(forget the model)

[@bitsundbolts]

Ah, I always lose those red plastic tubes 😞 But good point! I'll try to get one of those and see if I can work with it

[@5Breaker]

That thumbnail made me laugh hard x‘D

[@bitsundbolts]

Haha, great to hear that!

[@leakyabstraction]

I remember visiting my friend's place, where he showed me Tomb Raider being played on a CPU like this, and it was unbearably slow (in higher resolution), in fact I was wondering how could he play it like that, but I didn't say anything because I didn't want to hurt his feelings. Also, meanwhile I think I still had only a 386SX at home, which was related to a sore disappointment of my childhood... My mother bought that 386 PC for me in used condition, and it turned out to be an SX model, not a DX. 🙈 Btw, to be honest I totally didn't get the point of 3D games for the first few years... they were so ugly compared to the already relatively refined 2D games that used sprites. I think one of the first games where 3D was appreciable for me personally was Little Big Adventure, where the characters are 3D; it was such a great game! I still remember the computer magazine where I saw it first - that was the period when games started to get pretty impressive, not much later e.g. Command & Conquer also came out. Subsequently I was lucky enough to find Little Big Adventure on our school's computer; I still remember how excited I was when I saw that three letters folder name (lba) in Norton Commander. If I remember correctly, it took an ungodly amount of floppy disks to copy, and one of them was bad, so I had to go back to the school and copy it again.

[@pc-sound-legacy]

Awesome cpu rescue 👏

[@lexluthermiester]

@BitsundBolts As usual, well gone on the pins! This is likely the best non-Pentium CPU you can get for Socket3, especially with the easy OC.

[@charonunderground8596]

Amazing job. You are Master !

[@bitsundbolts]

Thank you 😊

[@MrKillswitch88]

The last time I fixed anything that bad was a K5 that of all places was from off Amazon, didn't lose any pins thankfully.

[@bitsundbolts]

I hope to find a K5 some day as well. Never used one of them. Great job not to lose pins!

[@johnhogsed-lg4lu]

it does say Am5 so it must be new

[@buffalodebill1976]

After an XT-class Atari PC3 computer, my first "AT" PC had exactly this CPU (the AM5x86), 1MB of RAM and the S3 Trio64V+ graphics card. Sweet memories.. 🙂

[@gctechs]

1MB of RAM? Shouldn't it be, historically speaking, 4 or 8 MB of RAM?

[@buffalodebill1976]

@@gctechs Historically speaking, you could put in as much RAM as you wanted or could afford, into those PCs. Mine was built by a local company and they put in exactly 1MB. Yes, the price of RAM was a factor there, but from what I recall, I could live with it for more than a year quite fine.

[@lucasrem]

I got Tomb raider for Christmas that year, bought the MMX Pentium PC for it, better fit for my Voodoo card.

[@BigReady]

Very impressive. Mr. pin pro straightener. 👌👌👌

[@Taorakis]

Guess with those bent pins the good old "bend them back by pushing the CPU into the socked"-Method would've done nothing. :D

[@bitsundbolts]

Yeah, that would have been pretty hard :)

[@Beus38]

:-D You'd probably completely destroy both CPU and the socket in the process :-)

[@ninjamaster3453]

I used to do system build during this era. I never imagined these chips would be considered today for a retro build. If I come across any relics should they be saved or recycled?

[@bitsundbolts]

Those chips fetch more money when saved and sold to collectors and retro enthusiasts - provided that it's a working CPU. There are still some to go around, but they will get more scarce over time.

[@levondarbinyan3934]

Hi, you could use metal pen refill to fix the pins back. Much easier than to work with toothpicks.

[@amnesiac-original]

It was a pleasure to watch

[@Aeduo]

Wow what a substantial upgrade one could've made for their aging PC in the mid 90s to get a couple more years out of it before having to replace it. I wonder how it'd do with Quake. It might be just nipping at the heels of being able to run Quake playably (by the standards of the day).

[@bitsundbolts]

The weakness will be the floating point unit to run Quake on a 486, but overall, I really like the socket 3 platform. So many CPUs and different flavours.

[@romaneberle]

9:27 lol. that's super weird. i'm watching this in fullscreen on an old laptop, and an even older display.

[@criticscooby]

I think this is a great result, how much was this CPU? Because if this was a top model than it was a bad investment even tho I think the performance increase is pretty noticeable to me.

[@bravo1111]

Gute Arbeit👌. Once again, the pinarmy stands at attention💂💂💂

[@bitsundbolts]

Haha! YES!

[@SidneyCritic]

The pins look like gold coated steel, ie, you would have to get them glowing before they get in to the plastic stage - lol -. I would try a pointy hobby blade for that Diamond.

[@pazsion]

i found a mechanical pencil often fits snugly and allows you to bend at the base and then get the kinks out too... without tools

[@trex70]

Realy nice repair

[@bitsundbolts]

Thank you!

[@MrRetrostage]

Played Tomb Raider on a 486DX-2 66... Wasn't possible in some areas. 😂 Upgraded to an P200MMX with 3Dfx after some months and this was wonderful.

[@ikannunaplays]

Same, but never upgraded to a Pentium, or 3Dfx card. Still had a smashing good time on it. If my memory serves me I used some DOS TSR's to improve performance as clock speed only yielded so much. I remember it being a smooth framerate and not a slide show. But that was long ago

[@GiovanniVazzola]

I've played alot in my 486 dx2 on OC 😉
