Q6600 VID/Voltage/Overlocking question.

[kimyeang88]

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.

Thank SAAIELLO.

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