Overclocking Q6600 GO with Asus P5KC

post #1 of 3
Thread Starter 
Hi,

I'm new to this forum (and overclocking) and am looking for some advice and a sense check on my progress.

I've currently got my Q6600 overclocked to 3 GHz (9 x 333) from 2.4 GHz stock. It's running stable (Prime95 Small FFT's 12 hours) with the following settings on my Asus P5KC motherboard:

Vcore (set in BIOS): 1.3625
Vcore (reported in BIOS): 1.304
Vcore (CPU-Z): 1.304 (idle) 1.224 (load)
DRAM Timings: 4-4-4-12 @ 667 MHz (rated 4-4-4-12 @ 800 MHz 2.1v)
DIMM voltage: 2.1v
All other voltages set to [Auto]

I really want to try and minimise the Vcore further to try and keep my temps down (and also just to learn more about overclocking). On slightly lower settings it will boot to windows, but Prime95 reports an error after a short time. Can I improve stability with a lower Vcore in any way? My CPU VID is 1.325 (I've read this is high, so I've been unlucky there , is this likely to be preventing me from achieving a lower stable Vcore?). I've read about people increasing the NB voltage - could this help? I don't know what my NB is currently set to on Auto, is there a piece of software I can use to report the NB voltage?

Any advice would be a great help!!

the higher the voltage the easier it is to overclock. Not all cpu's are made the same. So what someone else gets you might not be able to. That being said, you have a pretty average setup.

In most cases you dont need to increase the NB only in rare cases. alot of the time ram can prevent you from going over a certain limit. You can always try increasing ram speeds to help stabalise your system.

If you undervolt your cpu then you will have to decrease speeds on the cpu.

Thanks for your advice!

Does anyone know of any software that can report the MCH voltage? I've got MCH monitor, but it doesn't seem to have the MCH reading...
