Thread: Overclocked a PII to 1.6ghz

i think it could be with watercooling and bumping up the voltage.

ihmmm, yes i do

I don't believe he actually did it.

Doesnt seem likely.... he says he used air cooling (doubt it) and he hasnt posted any pics of this overclock.

There's alot of crap on the internet (i would say 80% of the facts on the internet are not facts)

No. Even with extreme cooling methods, there's a limitation on how fast that CPU could go. The man is claiming a 300% overclock. There is no reliable evidence that any Pentium II could go that high. 50% overclocks are considered to be on the high-end of the OC percentages. I'd give him some credit if he said something like 700MHz. While that's still out of the range of most OC's, that could be a reasonable OC.

That guy is talking pure bullshit. Find a reputable person that has OC'd a Pentium II, not III, to that level of an OC. You can't. He hasn't.

its only 800mhz over stock.

someone got a pentium 4 to 6ghz with extreme cooling once i think.

The pure fact is willhub, that ancient ruin of a CPU could NEVER go that high, it just can't be done!

Impossible. The L2 Cache on the P2 was already slower than the CPU's clock speed. He'd have to disable both the L1 cache and the L2 cache to get anywhere near the claimed overclock, and even then I'm sure it's not true. Do know how much volatage he'd need for that junk? Even if it was possible, we're talking liquid nitrogen and a custom voltage regulator. But the fact remains that it's simply not possible with a freaking .25 micron process!

It's BS.

I heard someone took a p4 to 8.3ghz but knowing p4's it probably died the next hour.

Got a link? I'm interested to see how long the CPU life lasted, and what kind of cooling they used. This kind of stuff interests me a lot

He's claiming nearly 1.2GHz. That's nearly a 300% increase over stock...and he's claiming he's done it on air. To be honest, the motherboard he's stated to have, the Asus P2B-F, would have to have a selectable FSB of up to around 400MHz. Motherboards back then did not have that high of an FSB. Could he play with the multiplier? Only downward...and given that wouldn't helped him, that would've been a stupid move.

As AT already mentioned, the manufacuturing process of .25 micron is incapable of that speed. If Intel could've gotten the PII to 1.6GHz, why did they need to change the design that much and go to the 0.18, 0.13, and the current 0.09 micron process to hit today's speeds?

While I know some people can hit some nice OC's with extreme cooling, the fact is, it'd be very difficult to get anywhere close to what that guy is claiming. The Pentium II only went up to 450MHz due to their design. Yes, someone with a 3.x P4 has likely hit 6GHz, but the design of the Pentium 4 allowed it to scale extremely well. The Pentium II is nothing like the Pentium 4, save some basic architecture (x86).

If anyone here actually read the whole 8 pages of that thread (like i did when i was bored), he got cought out at the end using a Celeron 1.4Ghz with a Powerleap adapter!
