Hello Everyone,

I just want your recommends on what cooling device is best if I wanna overclock my K6-2 350MHz to 500MHz ?

Thank You!

Most of us with 450s can barely reach 500MHz, let alone do it on a 350. You would be quite lucky to reach 450MHz, but most probable for you is 400MHz or somewhere around there. The AMD K6X series, in it's current form, is not designed to run at speeds of 500MHz. Unless you got a really good chip, you are going to have to wait until AMD releases the .18u and copper-based K6-IIIs before you can hit 500MHz and beyond.

Try it at 450 and if you can reach that, be happy.

I tried 450 but my computer will always crashed... and in CPUmark99... it got illegal operation... so I can only reach 400... what cooling device good for going 450... ?

Thanks.

Alphas are really good, but now I'd have to reccomend the Big-Mofo REX fan from 3dfxcool--that's the only fan out there that can best the Alphas. But make sure it can fit into your case, I've heard lots of people complaining about that.

Nuts N Bolts '98 shows that my K6/2-350 is running at 427mhz. That's with all the correct jumper settings. Is N&B accurate? My friend has a PII-350 and it has his @ 350. Why is this.

It all depends on your m/b and cpu you may be able to go up to 450 BUT you will have to increase cpu core voltage to meet the needs of the increased bandwith.

I had my k62 333 at 402.5 at 115(bus)x3.5(multiplier)at 2.6 volts.

you should try 100x4.5 at 2.6 volts,then 2.5 and see if its stable,by running some app's.

cooling -you might make 500 with 4 peltiers sandwiched and a liquid cooler at the cost of a new athlon..............

Thank You JGene for informing me that cool cooling device - BigMofo REX !

But Somehow... I live in Malaysia... I hope I can buy it here... cuz my dad dont likes me buying stuff from the internet using credit cards... as he does not trust that security cuz Malaysia havent got a VERY GOOD security...

anyway Silicon Scream, 427 speed is by the bus speed 95.25x4.5 and it will be 428 if u divide by urself... I got that speed and it runs stable... somehow when I benchmark using CPUMark99 and compare to 100x4 = 400 ... the 400 is even faster then 427

Well cuz the bus speed is more important in perfomance... somehow my motherboard fried up when I tried to get 112 bus speed cuz someone tells me to add more voltage - I put 3.45 and it fries up... unstartable anymore... I am waiting for my dad to send it to the shop where I bought it (well it's far away from my house... takes 2 hours to get there)

I've ordered from 3dfxcool before, and I heard one guy who ordered his fan and he lived in England, so overseas shipping is of no problem to them.

As for your motherboard voltages, I am surely hoping that you are talking about a 3.45V i/o core and not the CPU core--which is only rated between 2.2V and 2.5V on K6-2s. Running it at a voltage that high is a surefire way to BBQing your chip.

I bought the K6-2 with a motherboard...
recently the technician helped me to install these things... and what I discovered is that he put the CPU core at 3.2V

so Is he wrong ? he should be sued ?

anyway... is my 230watts power supply is enough for that 3dfxcool FAN ?

Thanks.

Your technician should go back to school,CPU at 3.2volts? My MB wont even go that high.you will burn that chip out real quick,set it at 2.2-2.4 vdc.My K6-2 300 runs at 400 with 2.3volts.

Yeah that was what I was thinking... 3.2V is too much and it will fry my cpu... I should have complained to them of what have they done to my CPU... they do this to make more money !!

They think that I was young and dont know anything about this... now IF they dont give me a claim from the warranty... lets see what I will do to them - complaints sent to the consumer association!

That is what I gonna do!

On my very first attempt on putting my computer together, I had set my brand new mobo and AMD K6-2/350 at 3.3v... I tried starting it up once and it didn't boot.
Heh oops.

It's a good thing, now 4 months since, it hasn't had any ill effect on my CPU. Needless to say it's been at default 2.2v... and running at 400MHz with no problems.

Failing to overclock to 450Mhz or 500Mhz using 350Mhz K6-II has nothing to do with heat. K6-II are not overclock friendly like 366 or 400Mhz celerons.

I can only overclock my 350Mhz to 400Mhz and not beyond even with all the fancy coolers in the world.

I have now a BP6 with two 400Mhz celerons easily overclocked to 558Mhz each with a standard fan/heatsink...


A BP6 and two 400Mhz celerons for $284.00...not bad...

link to info on the best k6-2 cooler out there, its huge but will cool ur cpu with great results, my 400 is at 450 and NEVER has crashed, got to 472 without any problems and 500 would crash only under heavy quake 3 benchmarking. u can buy the cooler for $19 at memman.com

I have been running my K6-2 350 @ 448 (4*112/2.7v) for the last month and a bit with a slighly modified heatsink/fan and no probs at all..

Hey, I have had Problems underclocking AMD K6-2 300's at 250Mhz (83Mhz FSB). WinNT and LINUX are ok, but will Win9x start?...Hell no...

And, if I wanted to OC my K6-2 300 to 450 or so MHz, the only cooling I would recommend is liquid nitrogen. I will believe anyone if they tell me they overclock by 50Mhz on a 300Mhz+ CPU...but 150Mhz?
You are nuts. The cooling equipment, and the early replacement of the CPU you will undoubtedly be forced to do will be more expensive than a Dual PIII 450 system...
