Rely on bios volts or windows programs ??

[scotslad]

Just trying to get a few things confirmed here.

Ive been having a twiddle around adjusting the cpu voltages in my bios.

First of all i notice in my bios it gives the volts in "mV" as apposed to Volts, i guess mV stands for millivolts, does it ? if so, how many mV = 1Volt ?

I have noticed in the cpu Vcore in bios it says the voltage is set at -0.020mV, yet in the bios hardware monitor section it says 1.224V, and then to make matters worse, lol, in everest it says the cpu core voltage is 1.03V ?? (i think i got that correct, lol, ive been writing notes down).

so you can understand why iam confused, does anyone know what iam talking about and can explain please ?

Thanks.

mV does indeed refer to millivolt. I have absolute faith that google or general knowledge should be able to supply that there are 1000 of these in a Volt, just as there are 1000 ml in one litre.

The -0.02 means the voltage is set to 0.02 below the default for your processor.

The hardware monitor section tells you the voltage being applied to the processor.

Voltage reported in windows is often lower than that in the bios. This is Vdrop. It should not be that large a difference, I recommend asking cpu-z to confirm as Everest may be wrong here.

Most people quote voltages in terms of cpu-z, not the bios, as verious people applying multimeters to boards decided cpu-z was normally closer.

I hope this clarifies things

ahhh i see mate, your info certainly does help, thanks.

i have those volts i refered to on previous post with my i7 920 cpu is clocked to 3320ghz (thats what it says in boot screen anyway, lol), should i apply slightly more volts to that then ? and what would you recommend as a good average volts for that clock ??

also, i notice in bios my dram volts is at 1.47V, its corsair 1600mhz ram i have, but i can only manage to get it to post up as 1328mhz in boot screen, do you think increasing the volts would fix this, and if so, what should i set it at as a good starting point ? (or would i need to take my base clock up to 200 to get the ram speed correct, its currently at 166 ?).
