As of mid-2006 I was still using my old K6-2, and had done almost exactly that. I had made the 256kb mod, and soldered the wires for on/off, to a relay with the resistor, and the other end of the relay, went to the turbo button of the case. When the turbo button was pressed (light on) I had L2 cache enabled. It was an amazing pc full of other mods

Imagine knowing this back when these were first available, who would have the guts to attempt it though?

Neat! You can also disable the L2 cache on-the-fly with the software-based SetMul utility, in addition to changing the CPU's clock multiplier for running older speed-sensitive software.

Here's a tip for fixing bent CPU pins without danger of snapping them off. First look at light reflecting off the ends of the pins. When you see a dark one while most of them are reflecting, the dark ones are bent. Second step, find a syringe needle that will just fit between the rows of pins. Slide it in so bent pin(s) are leaning over the needle then lift the needle up and out of from between the rows. That will gently nudge the pins towards straight. It can take several times to get pins straight enough to go into a socket. For badly bent pins, find a syringe needle that will fit over a pin. Clip the point off and use a sharp knife point to deburr the hole. The needle provides leverage and fine control to carefully straighten the pin right at the point where it's bent. Just straighten enough to be able to slide a needle between the rows. I did this with a lot of socketed CPUs, AMD and Intel. A video on it could get you a lot of views.

I had the K6-3 which was one of my favorite processors of all time.

A surprisingly clean setup with the jumpers! The on-die thermocouple is a nice touch, too.

It's amazing how, as the time goes by, we still find new stuff about the processors we saw (and enjoyed) during our childhood! Great work My friend! Cheers from Argentina!

Love your project and how you solved this with copper tape. Great work and super documented. Definitely worth to subscribe. 😊👍🏻

I miss super socket 7. You could run a 2nd or 3rd gen Pentium all the way to a K6-III+ at 600MHz. I counted it up one time, something like 17 different CPU types fit that socket, I think 14 different architectures. It was crazy, you could literally test *all of the CPUs* on the same motherboard, just power down, swap the chip and give it hell. Fun times.

Wow! The idea with the jumpers is super cool, well done!

Just popped up on my recommendations. Great video man!

That is an awesome mod! Well done!

really enjoyed the video, interesting topic. Maybe a longer music loop would be nice when played for longer passages through the video :)

K6 was my first build on windows 95, then on 98. From there I went with the K7, no need to remove the lid, the die was already exposed. However, if it wasn't, I sure wouldn't have used a double sided razor blade... Lol. You sure were risking it with that blade, no way would you catch me doing that. Those things are super freakin sharp, one good slip up and it's down to the bone real easy... geez 😭

Nice video, Information might be irrelevant these days but, Yeah!!! if you can do this back in the day you are a genius!!! A very great hardware hack!!! thanks for bringing it back. Feels nostalgic.

Very nice :-) Cpu identification utilities need to include that new CPU ID now I have been mentioning it on vogons to a few over the authors

Still have my K6-2 550mhz rig up and running, great machine for dos and early win95/98 direct3d games

I love hacky stuff like this. Physical mods that allow you to do things you never thought possible.

Nice job! When I was working at a recycling center I scrapped so much K6 variants that it's weird seeing someone handling one like a precious artifact.

Excellent :)

Great content, thanks, fantastic mod, really interesting stuff, subbed. Mike from vswitchzero sent me here btw, glad he did.

Very good video. 👍👍👍👍

This is amazing! I will try it for sure if I can grab that sweet pack from eBay!

awesome job

Nice!

Sehr schöner Mod ich hatte mit damals den K6-3+ 550 gekauft

Man... i love the internet. I never though id ever see anyone delid a k6 let alone modify it to this level.

lol this reminds me of when I cut and modified the top of the pcb on my athlon 1800+ to turn it into a mobile server cpu with a unlimited clock multiplier.

My first PC was a pre built in 2000 Compaq Presario 5410 it had a AMD K-III 350mhz, 32mb Pc100 RAM onboard graphics 22 years later now I have a Ryzen 3600 16GB RAM, RX580 8GB how far games have come on and hardware has improved through time and tech.

Very nice mod.

Ahhh the good ol days when different brands used the same socket.

Wow I had this mod already in mind, except for the disable option. And now comes this video.

ну ты и маньяк, монстра Франкенштейна собрал :D

Congratulations

amezing !!!!!!

I guess if you want to go an extra step you can design a flex cable to do all the wiring :)

I remember frying my first k6-III trying to overclock it. Those were the days.

Always loved the K6-2 when it came out. Now rocking a Ryzen 5700G , yep AMD fanboy lol.

i had absolutely no clue you could unlock more cache on these, man whatta missed opportunity on my part

I’m from 2000 with thanks for the mod)))

Nice. I am using that very same DFI motherboard. I'm running a K6 III+ 450 at 550Mhz stock voltage. It will run at 600 as well at stock voltages. Heatsink is never warm. BUT I want to stay at least relatively safe.

WOW!!!!

you can also make a breakout with a fpc cable and have the jumpers at the front of the pc

omg i remember that 3d-now

same with phenom x3, easy bios flash and u have phenom x4 :D

Wow, didn’t know that a delidded k6-2 looked like a socket a athlon

I don't remember what version of K6 I had as a kid, but it was the 333mhz I believe.

Nice!! How about delidding and then laying the jumper wires on the ceramic and then 3D printing a shim to hold the wires and do direct die cooling? :)

Im glad that I'm having here some super 7 cpus... (some penitums; i200; some undifined and some mmxs) and for the best; an k6-2 550; dont know where i got that; but in the near future I am going to search for an proper good ss7 board as a benchtable for theese cpus and as a retro gaming machine.

The way you handled that razor blade ... do you still have all your fingers?

I want to put some light on amd sempron 145 single core cpu which was able to be get converted into an athlon 2 core cpu by just a simple cpu unlock setting in motherboard bios.

Are the any mods for nowadays CPU?

Is this applicable to all models - i got the 550FX/ K6-2 and does the motherboard play into this - like bus speed, tiny variations in voltage ?

Wow.

Great Video! Just found it bc i also built a K6-2 550 rig. Now a question: Did you run any benchmarks to see performance differences between the various cache settings?

550 luv bouyyyyyyyyy sgit is still my fav 7 cpu sick yo

Would uv solder mask and enamel (speaker) wire not be better options than kapton and the copper strips?

How did you discover the required information about what the exposed resistors etc do underneath the heatspreader? Was this information already documented by AMD and publically available? Did you have to check voltages and randomly short out pins and test? How was this worked out?

hello. i have a k6-2 380mhz. are there any more for these?

Please try overclocking it with cache disabled. I would love to see, what a K6-2 would have been capable of, it AMD had used the same 180nm node for it, just like for the K6-2/3+ CPUs. K6-2 @670-720 maybe?

Can a regular K6 be modded into the + version by doing this mod?

dumb question what is the vaule of the Cap that needs to be moved i broke mine while removing it

Plug the cases Turbo into one of the new jumpers. I would go for the cache jumper myself.

I wonder how it would cope with the jumps being changed in-flight.

Loved the chip mod, but why are you running that lousy stick of ram? Swap it out for one that is CAS 2 rated.

is there any way to mod the vanilla K6-2 (CXT)?

i remember this. i got 1ghz out of a k6 literally for years. i actually never had any problems.

Is the temperature tool Win9x compatible?

Maybe someone can explain this weirdness to me: I had a friend who built a K6 2 400 system based on my own. He liked how well my computer performed that he built his with the same processor and motherboard. He made a mistake with the jumpers on the board and when he first powered it up, it blew three pins off one corner of the processor. He brought me over to investigate and I found the incorrect MB jumpers. We set them where they belonged, powered it on and... it booted. We installed windows, installed the bridge drivers, the nvidia drivers and the audigy drivers and all was well. Except - it benchmarked 15% BETTER than mine in Final Reality. HOW?!

Is it okay to short circuit pins and not using resistors?

Not that I'm suggesting that you actually do it but I wonder what would happen if you change the jumpers on the fly. Btw: Anybody noticed the TÜV logo on the CPU cooler? - Real or fake? 😁😁

Next time i would put it in the socket with heatsink on to add pressure while curing

miss my k6-3 pc... dfi k6bv3 with 1mb cache ftw

I wish you done this video on 1997.. so I have mod my k6-2 to k6-3

But why would you, have the option to change the cache from 256KB to 128KB or even 0KB ? Its funny that mod was found 20 years later due date lol. Played around with this CPU too. AMD has a tendency of rebadging "full" CPU's as lower versions. The Slot A was a perfect example. Most cores where badged or rated for 750Mhz. But the lower end models such as 600Mhz, 550Mhz, 500Mhz, where just downclocked. The chip inside was the same as a 750Mhz Model.

Only a few synthetic tests were missing to see the changes

Next time bro . Use repair set for rear Window heater for the car . You know that heat lines on the windows what u use in the winter . That repair set is glue with silver or metal parts. Works perfect to make lines . I use that with my amd Duron/Thunderbird cpu. And you can use real silver pen more easy but not that strong.

You gave me anxiety using that razor blade with its sharp edge

А зачем назад поставил крышку?! Если можно было охлаждение поставить напрямую, на сам кристал.

Is this CPU galaxy moved on? Channel owner here I think has an Austrian accent. But excellent English, If he was CPU galaxy, his English has gotten better. And I would like to know why the switch.

The motherboard BIOS is patched? Imagine having both 256kB cache on the CPU + 1MB in motherboard, like a modern Lv3 cache 😎 What about some benchs? 128 vs 256 vs 1024 kB caches AMD K6-2 was my first CPU, i think it was 400MHz but i oced at 550MHz (my motherboard don't supported higher freq. and i didn't knew about BIOS updates) I wanna know what is the lastest Linux version which support this CPUs

I've got a few laying around (3 or so). Maybe I'll get one to work lol I really need a better motherboard though lol

👍👍👍👍👍

Back in my day we spread the thermal paste as thin and even as possible with a razor. 🙂 I'm old so what.

too much paste, far too much. Additional cache not tested. Video Link in 1:52 not working.

Under the hood, the AMD K6 looks like a K7 (Athlon) CPU, back in the early 2000s i modded a CPU arleardy.. An Overclocket ist A 500 to 700Mhz (unstable) i had no ideas of Untervolting or even thermal paste at this time, i was Young and Stupid. 🤣😂 Today thisa CPUs are rar to find, and the only one i have K6-2 500 i will never Mod or Overclock.

Even though I own this CPU, I'm not stupid enough to break it in such a futile attempt.

kindly remove the _entire installation package of internet explorer 5.5_ from the repository. StopMonitor returns a value that is never used. (even StartMonitor doesn't need to return anything, either. Whether it succeeded or not is known from _port.IsOpen) Do port enumeration at startup instead of in Start_click. Consider sending a short or an int from the arduino instead of a string. Consider handling SerialPort's ErrorReceived.

Hur Hur, will it run Crysis now? 🤓

The mission of the K6-III was to beat and harass the Pentium II. I think that the k6-III 600-666 mhz can beat the best pentium II, in all games, all applications. The pentium II had the best support in the motherboards industry, and so for the agp port, and sdram-memory They provide a bigger transfert etc. I think, its true. The worses errors for the socket 7, They had not motherboard who can support a system of dual cpu. its a real scandal into the super socket 7 History.

Де ти був 20 років тому...

Please don't use a razor blade like this guy did, it's incredibly stupid and dangerous.

useless mods are useless

Deutsche Wertarbeit 😅💯

This was amazing when I first found out about it! I was going to attempt the cache mod myself, but then I saw a listing on eBay of someone that does this mod... They've sold many and have great reviews. SOLID performance. I got mine doing 633mhz @ only 2.2v (115fsb) They still have a listing up. Item # 165591645766 It's basically a K6 II+ 570 turned into a K6 III+ 570. 256k cache! If anyone is interested, I'd probably snag one before this person runs out of em.

good example of ripping off people by AMD
