My trip to 600MHz on a 300MHz PII

[got_yogurt]

Currently I am running @ 450MHz, but then i figured, hey, what about 133MHz FSB??? that would equal 600MHz, Twice the speed, twice the fun... So, I taped up A14, and then fired the puppy up. Unfortunately, it didn't boot up... oh well. I dont know wther its the chip, or the MB. The chip is a 2voltz. Anyway, if you have any suggestons, please tell me.

P.S. My PII overclocked @ 450MHz is running at 21C under full load, 18C when Idle...

Maybe if you pop the case of that baby. Then you could cool that chip alot better. If you havent already done that. Although I just cant see you getting a 100% overclock out of a PII. If you did That is quit an accomplishment.

I'm trying to remember when I had my PII 400. They run at a 2.0v. Right?
What board are you doing this on?

[bdf24]

What are you using for cooling to keep that chip that cool. When I had mine it ran around 45c with stock cooling? A PII Alpha?

hey, sorry i didn't reply sooner...

I'm using the standard 2.0volts on the PII, The motherboard I'm using is a Gigabyte GA-686BX. I dont even know wether its my processor, or motherboard. It dosn't say anywhere that its rated for 133MHz FSB, but it dosn't say anywhere that its not :-). I have the original HS&F thats glued onto the processor by intel... But its my case fans that are the secret to keeping 18C even when overclocked. i've got two fans blowing sideways onto the porcessor, the a fan below the processor blowing up, and a fan above the processor blowing up again, and I have the top cover off of my case, so the heat just rises all the way to my celing. Its pretty cool.

what size fans are you using in there? 60mm's or bigger. And Man that has to be loud!

that probably won't happen unless you go into insane voltages and insane cooling methods.

the fastest Pentium II was a Pentium II 450...that's essentially a Pentium II 300 running on a 100mhz fsb.

i don't think you'll get 600mhz out of that because for one thing, that thing uses off-die l2 cache and runs half the speed of your processor. if i'm not mistaken, those things use 5ns cache chips so at 450, you're already overclocking your cache by 50mhz. you'll be lucky if you get that thing above 500mhz.

Even a PIII katmai 450 has a hard time doing 600mhz, mine won't...not without slowing down the cache

what about a 333? mines stripped (screwdriver cracking technique) and waiting for a nice double sided cooler to come in

Best I could get out of my old PII 300 was 504MHz. There's an easy way to find out if ya stand any chance at all of 600. You've already cracked the case, so look at the cache chips. If they say 4.5 or maybe even 5, with some EXTREME cooling ya might make it. If they read 5.5 ya can forget it. :)

which number refers to the cache speed on the l2 chips?

I noticed you have a Gigabyte GA-686BX. Have you heard of those bios saver devices? Someone screwed up a GA-686BX that I have by flashign the bios wrong. Would you bbe interisted in having one of those bios savers? I could send you 2 of them and you copy your bios to one and you could keep the other. I just want to get his board to work. Tell me what you think.

It's been so long, I don't remember exactly. Just scope out the #s and you'll notice one ends in either 4.5, 5.5, 5 etc.
