BEST WAY TO OC PII-400Mhz ON ASUS P2B-F?

[BuTcHeR]

I tried to OC it by changing the jumpers on my mobo but it didn't work, neither changing the FSB nor the multiplier! i think it's locked! please need some help!

The p2 starting from 333 & 350 is locked internally. The only way to o/c is to raise FSB. My 2 cents: Have you tried raising the FSB in the BIOS. Recheck your switches. Advice from Asus mobo owners would be good

I raised the FSB to 112mhz by changing jumpers! but nothing happened an its still at 100! theres no way to overclock it in the BIOS! need help! plz!

Whoa cool, I've got a similar system with the identical question.
I got the system in '98.. so does that mean it's unlocked? The mobo has jumpers to multiply the thingy (I'm new) up to 6.5, but the fsb is untweakable. I looked up a Globalwin VOS32 hsf which looks pretty good. Have I got everything I need? Is 600 even likely?

Arf, All modern Intel CPUS are multiplier locked. Without the ability to change FSBs, you can't do anything.

Try using SoftFSB you can download it at tweakfiles.com. This is a program thet allows you to change your FSB in windows.

My Pentium2 wasn't fully locked. It was a 350MHz version and I oc'd it a mighty 49MHz, right up to 399Mhz. I was able to drop the multiplier from 3.5 to 3, and even lower. I ran it a 133MHz FSB on Asus P2B rev1.0. I couldn't use the 112MHz FSB, because the PCI bus becomes 37.5MHz and it didn't like it. 133MHz on the other hand has /4 PCI divisor, so it worked like a charm. 466 was possible, but L2 cache had to be disabled.
Try lowering the multiplier by 0.5 or 1 and settings the FSB to 133MHz, I think that should work.

Oh yes, you need better cooling than the stock, as mine froze after posting w/stock HSF. An ORB solved the problem.
