I scored a cheap Q9550 (Microcenter) and decided to replace my 2 year old Q6600. Just to be sure that the board can handle higher bus speeds I run my Q6600 @ 400Mhz FSB for the last few days. Today I dropped in Q9550, booted straight to BIOS and loaded defaults (333x8.5). Saved and booted to Win 7. Run prime for about an hour with no errors. Temps were pretty good (high 20s/low 30s idle, low 40s loaded). Board vdrooped the Vcore to 1.09V during stress test and 1.11 when idle. Encouraged by the temps I bumped the FSB to 400 and set multiplier to 8 (3.2Ghz), again with everything set to Auto ... I got greeted with a massive BSOD. I dropped the FSB to 375 (3.0Ghz), again with no luck (this time windows locked up). I tried bumping all voltages, again with no success. Finally I tried 400*6 (2.4Ghz, which is a 400Mhz underclock) and again it locked up. It seems that I cannot go over 333Mhz FSB with this chip, although it did run @ 400Mhz with my Q6600. Oh, and the memory was locked at or below 800Mhz during all tries with very relaxed timings (6-6-6-18s).
Can anyone help?
