Q6600 VID/Voltage/Overlocking question.

First of all, sorry for my bad English.

I'm using Q6600 2.4 Ghz G0 rev VID 1.2500 V. Let say if i want to overclock to 3 GHz, the cpu voltage must be greater than 1.2500 or it can be lower ? because when i use Prime95 or Intel Burn Test(100% load 4core), the core voltage on CPU-Z is not even hit 1.23 at 3 GHz(my cpu voltage on bios setup was at 1.2675, i changed and it was not on auto).

Core Voltage on CPU-z indicate how much voltage your cpu is using or something else?

Btw, i tried to reduce my cpu voltage to 1.20 v below VID(1.25v) while i OC to 3 GHz. I did Prime95 for 10 min, it works fine then i just stop it.

I'm a bit new to OC. Thank

Hi and welcome the voltage is showing lower in CPU-Z because of something called V-Droop there might be some options in your bios to help with it but if you are not having stability issues I would leave it be and call it a day. Run Prime95 for at least 6 to 12 hours to check stability? Also I find that OCCT will find instabilities quicker.

Read this page to understand V-droop and also some great info in this whole article.

You should be able to run at 3.00 GHz with little or no voltage increase, even with the stock HSF.
