I've recently upgraded to a Core i7 920 rig and have a question about the default cpu core voltage. I haven't fooled around with overclocking yet, as I'll wait till I get a better cooler, so all settings in BIOS are on auto. The default setting on most sites I have seen gives 1.2 volts. However according to both Asus Probe and CPU-Z my system (using auto setting for CPU vCore in BIOS) gives a reading of 1.05. It moves around a bit though...from 1.05 up to 1.08 or so.
Is this normal, or should I manually set the vCore to the usual 1.2 volts? Whys should my rig opt for 1.05? Could that be a sign of a bad voltage regulator on the Mobo or some such?
Thing is, I've had a couple of crashes in usually stable games and am wondering if the vCore being too low could be to blame.
If you aren't overclocking, leave it alone. Each CPU has its Vcore set at the factory to a level that it will run fine at - the lower ones are actually the better CPUs, as they can run stock speeds with less power (making less heat in the process). Unless it crashes, it's just fine.
