Cpu-Z or BIOS for true Voltage

post #1 of 12
Thread Starter 
Im trying to find a prime95 stable voltage for my q6600 @ 3.6 GHZ.

Do I consider the voltage the cpu is getting as the BIOS voltage or the CPU-Z reading?

Also, Are there any quad fixes offered by Intel? I know before with my am2 rig theyre was the dual core optimizer and so forth.

CPU-Z will show your voltage under load which is what you want to know.

i would think the cpu-z one because that is the cpu under load.

The BIOS voltage will be higher than the actual voltage. This is called vDroop. Intel implemented this to make CPUs and motherboards last longer. There are no optimizers for intel quads.

so when people say theyre running 3.6 ghz at 1.4 volt... that means that theyre getting 1.4 on the cpu-z under load? not in bios? it changes quite a bit i have noticed.

Remember, SpeedStep will drop the voltage and multi so it idles at a lower speed.

I refer to my cpu-z voltage , I dont think i would really refer to it as under load , but moreso than when in the bios obviously the drop. But when you run orthos or prime then there is further drop and fluctuation thats when its really under "load"

ok cool. Yea i have disabled all the things in bios like speedstep and such, anything that hinders OCing.

So, I am currently at 1.5v in bios, but my cpu-z id says im at 1.42v. temps are at their highest 57c so far, running prime on all cores.

Im assuming if i wanna up my volts its ok, although i like 1.5 as a limit on air. But if the vdroop means im at 1.42, and temps are below the spec of 71 then im ok to go BIOS 1.55v?

in theory, you'd be ok, but I (and most) would not often go above 1.5 in the BIOS

quads are the shortcoming of the 680's, unfortunately..
