Overclocking: How can this happen?

[jima]

i have a p4 3.0 withe a asus p4c800 deluxe and 1024 mb of cosair pc 3500 ddr. I can only get my overclock up to 215 or around 3.27 since i cant unlock the multiplier. Just the other day i dropped it down to default and went into a game and checked frames. Then i went back and bumped it back to where i had it overclocked at and went back into the game. and low and behold i noticed that while i was overclocked i actually lost a few frames. can anyone explain this.

Are you certain that no other parameters (i.e. memory speed or timings) are changing when you change the FSB?

Are you playing the same area in the game? with the same settings?

yes i leave my memory times set the only thing that is on auto is vcore and memory voltage. and yes same place in game. its actually nascar 2003 i jsut sit in the pits same scenario. maybe i will try this again. i take it that this should not be happening. also how much of a gain should i be seeing from 3.0 to 3.27

It certainly could be happening if your cpu is getting into the thermal throttling.
How hot is it under load?
My benchmarks drop like a rock if I run mine @ 3600 and a .1 volt boost.

sounds like you lost PAT going past 200fsb.

well to answer your questions at full load while gaming i only hit between 36 and 40 degrees celcius so not bad. and for the other what do you mean by lost pat. Thanks guys for the info
