Hey, have anyone got CPU, that limits FSB overclock by itself??? I cant find the other solution, this chips looks good, but it will not go past 450 FSB in Intel Birn Test.

As far I could get with 1.7v PLL and 1.4 FSB was 455 FSB, at 460 it freezes somtimes during the test, I was using 150 loops of IBT (sometime freezes at 80 - 90 loop). Now Im at 450 x 8.5 that is 3825 Mhz, PLL at lowes 1.5v, but FSB still need to be 1.3v, NB to 1.55 with 4 x 2Gb memory @ 900 Mhz. This is with P35, Asus P5K-E, there was no problems with this board up to ~ 480 FSB before with Q6600. I have tried 1 dimm single memory and that gives nothing. No luck, even cant boot @ 470 with volts maxed ou, GTL tweak gives nothing.

Is that the CPU limit? Its pretty good, as with IBT it needs only 1.216v under load to complete 50 loops of IBT at 3825 Mhz, I think this is realy good, but no more fsb, so no more mhz after all. Max load temp IBT is 52 on all cores, good watercooling.

Its 1.275v VID chip L845B, +1 Ghz overclock with lover volts than VID
