Well i've got one hell of a celeron.. its been at 204 STABLE, at 1.575 vcore. Once i hit 205, it just bugs completey out and restarts. At 1.55vcore, 204 is stable, and I can hit 4.1ghz but then my memory bugs out.

So. My DS3 is glitchy and my shop won't RMA, and I don't rma stuff because i don't wait that long. Memory is messed up when I set timeing below stock, so i said w/e i'll keep it. Last night i found that on the DS3 when overclocking, my fsb-memory dosn't like 2.00 (1:1), or 2.50 (?:?), but rather 2.66 (3:4). My ram blows, its kingston 512mb value ram DDR533. Its fine if i put the timeings all the way up to 5-5-5-15 @ 266mhz and then overclock, and bump up voltage a bit.

Last night i tried once again, to break this wall. I was at 205mhz fsb, both ram and fsb seemed fine after priming for about 5 minutes so i bumped it up to 206mhz fsb, then my pc crashed and restarted. Is this my memory or my PSU? Or my celeron? Last board i had (P5P800), my celeron would hit 203mhz fsb and wouldn't go over, not even if i bumped it to 1.6vcore.

Temps are fine for my CPU, im useing a sythe ninja, and my load temp at 1.575vcore 204mhz fsb was like 53 or something. PSU is a entermax liberty 400 watt with <80% effiency and good 12V rails.
