@ mw86 Thanks man, I learned a lot from this. I was using flex at 25, so I should set this on 0. I was OC yesterday and I got 90 C temps on the CPU package, maybe it was because of that flex value. I immediately turned emulation off. Since there's no IC Diamond or cooling pads here in Mexico. I got a small table with a perfect rectangular hole in the middle and placed my PC there, and it gave me better temps, then I placed a small but powerful fan below and I was getting a stable 4.2-4.4Ghz with a Max temp of 82 C after 2 hours of emulation, and the little fan was a the lowest setting @_@. Maybe its the winter, but in the summer time I'll just yank the fan up a bit. My values were 45 45 45 45 my mistake on the flex 25, and everything in the power to max, but I did not OC the memory, I'll try that, FSB was at 99.80 thanks for that suggestion too. My hardware is 2960XM 6990m CF 1600's ram i think, and 2 7200 HDD's. So if i monitor the temps and they're not climbing, should I continue to use maximum settings? What do you advice? should I keep flex at 0 when im using more than 4.0Ghz or yank it up? Since i was afraid of using hwinfo64 to override the fan problem, im using that load optimal settings in the BIOS fix, and its really working wonders for me, the right fan doesn't turn off anymore. Thanks for taking the time for this mw86, and for the details!
