Vcore voltage - read in bios or CPU-Z?

Just a quick dumb question....

When people are quoting Vcore voltages on here do they mean the value in the bios or the real value as read in CPU-Z???

Mine is set at 1.45v in bios but reading 1.39ish in CPU-Z, this is with a Q6600 which is only clocked to 3.2, drop the voltage a notch and it keeps freezing up!

Read all the posts saying don't go over 1.5 but not sure which value to use? I presume its the CPU-Z figure.
 
i normally take it with a pinch of salt and go between both

the reason windows reads it lower is because of vdrop

go off the one in windows

but dont push it to the limit unless you know exactly what you are doing
 
So is it still not safe to go above 1.5v even when I have a water cooled processor? At 3.2 it never goes above 45deg at moment even under full load.

I can see the voltage going over 1.5v before the temperature becomes a problem.

Whats more important - voltage or the temperature? Can the voltage still damage the processor even when it is relatively cool?
 
watercooling or no watercooling
there is no point in overvolting it if it doesnt need it

when clocking up and getting to a stable frequency

you should then drop your voltage in incremenets and check for stability

this way you find the minimum stable voltage for your chip

there is no point in giving it more than it needs - and it shouldnt need 1.5 until about 450fsb

Mine requires 1.54 after vdroop at 3.4Ghz, which is 1.61 in bios. I've been running at this for yonks, without any signs of problems.

My board has crazy vdroop, and unfortunately I have one core on my quad that just hates to be clocked higher than 3.3 :(

Wish my board had gtlref adjustments!
 
When i had my e6600, it was a greedy bugger for volts 1.525 set in bios, 1.488 in windows for 3.6ghz. that was on my old evga 680i which suffered from a bit of vdrop/droop. Pushed it to 3.7ghz once for a few benches but i needed 1.575 ono. My quad on this new board will do 3.6ghz on 1.4125 bios, 1.400 idle in windows and 1.416 @ load in p95 smal fft.
