What exactly is the point of the MCH voltage in the BIOS? I think someone said it deals with the voltage that flows through the northbridge which regulates the connection between the cpu, RAM, and gpu if I remember correctly, but what does this have to do with overclocking your cpu? Does it make your system more stable? Does it allow for higher FSB? If I am ocing a q6600 which doesn't exactly need a FSB higher than 400 if only doing 3.6, does it even matter to change the voltage?
I mean I oced my q6600 to 3.6 at 1.5v in BIOS (1.41 according to motherboard, ABIT IP35-E, software however) and was able to get it prime95 stable for 10 hours (have TRUE and low ambient temps so temps were about high 50s, low 60s) but, being an ABIT IP35 board (I here the IP35 Pro has high PWM temps as well) had extremely high PWM temps and so I was only safely able to run stability test onside of case and with fan on MOSFETs. Anyway I ask if MCH voltage is important because I was wondering if increasing the MCH voltage means that I could lower my cpu voltage to possibly lower PWM temps?
