Recently installed and Phenom X2 955 95 watt processor (3.2, on approved CPU list) and have noticed that when I overclock it above 3.2 it has problems with soft reboots (let us say 40% of the time) and goes into bios safe mode. It does this if the CPU is overclocked to 3.5 or even a slight overclock with standard voltages. No problems when not overclocked. The m61p-s3 also did this with the previous athlon 64 X2 ada600iaa6cz which rarely did it once I slowed down its overclock to 2.95. Soft reboots are rebooting the operating system from the windows 7 64-bit start menu or control alt del at the time the bios asks for the bios password.
The 3.5 overclocked X4 has no problems cold booting nor running any diagnostic test or software. Soft reboot will fail even on a cold machine.
I did notice that the motherboard had 2 bad capacitors next to the CPU and replaced them with high quality replacements rated the same (it does boot faster since then). Could the other capacitors also be bad?
There is space for a sixth capacitor next to the cpu so maybe I should add another? (the theory is the motherboard did not have time to recharge the 5 capacitors).
Unlikely to be a CPU issue since I have seen it on two CPUs.
Perhaps this is a bios issue/limitation with processors faster than 3.2?
Anyone else with a X4 processor and M61P-S3 motherboard with a processor faster than 3.3 with this same issue? (Delayed answers are fine since I know there is a smaller group of people with a similar combination with this motherboard - other suggestions also welcome)
