I managed to get my Phenom II 940 to 3.6 Ghz stable just by changing the multiplier to 18x and raising the VCore to 1.5v. I then tried to raise my FSB to 206Mhz (for 3.7) and it failed prime95 blend test. Anything more and it would BSOD or just crash. I've tried raising memory/NB voltage to 1.2v/1.4v which didn't help. I tried lowering the multiplier to 17x and raising the FSB to 220, same thing. I also tried raising/lowering my NB multiplier, no difference. I limit the memory frequency and let the board choose my timings: FSBRAM 1:2 (seems low?), 5-5-5-15-23 currently. My temps are good CPU idle 28C, load 34C. Any ideas on what is causing these problems when I raise the FSB? Are BSOD/crash/prime95 failure caused by different things? I'm a semi-noob at overclocking so maybe I'm missing something... what do I need to consider when raising the FSB? Thanks in advance!
