So I commenced overclocking. 3.2Ghz - no issues 3.4Ghz - no issues 3.6Ghz - no issues either. As you can see, temps are great. However, when I was at 3.6Ghz and went to the bios to put the FSB at 401 - I found that somehow the cpu voltage had been set to 'auto'. And it said 'auto' in yellow (all other bios fonts are white on blue background). It was supposed to be at 1.2V because that's how I had put it. What's more, I didn't have the option to change it from auto! I rebooted a couple of times to check if I was missing something... in vain. The only way I could get back the voltage choices to show was to revert to 3.4Ghz, reboot into Windows, restart pc and enter bios again. Notwithstanding this stubborn 'auto' voltage glitch, I decided to try for 3.8Ghz. I put the vcore on 1.2V again... and.... booted to Vista with no problem at all at 3.8Ghz. But OMFG the temperatures!!! I was idling at 51 degrees... and just 12 seconds Orthos got me 64 degrees on RealTemp and 68 degrees on CoreTemp! I quitted Orthos after 12 seconds because I really didn't want to see what maximum temperatures I got... So I got basically 2 questions -- 1) Is there a way I can prevent the bios from automatically changing the vcore I choose to 'auto'? 2) What is the reason that at 3.6Ghz I get awesome temperatures but at slightly more 3.8Ghz I get awful temperatures? (My vcore got changed to "auto" both at 3.6Ghz and 3.8Ghz. Thanks!
