Safe Overclocking P5B/E6600

esieens · 20 Sep 2006 at 05:44

Hello,

I just got a E6600 and a P5B DX.

Memory:- Geil 2GB CAS 4 PC6400 at 800MHZ
Case: Antec P180
Video: x1950xtx

I am using the intel stock fan and the 3 Antec fan in the case are at low level.

I want to safely overclock just a little bit my CPU.

Could you please let me know what would be your recommendation?

I'm really not looking into breaking a new OC record but just getting a bit more from my kit.

Thanks,
David

A safe overclock would be 3 gig. Most E6600's will do this on stock voltages. Simply raise the FSB to 336.

Thanks for the quick response.

So I don't need to change anything else? Memory? PCI?

Thanks

Set your pci to 33.33mhz
Set your Dram as close to 800 as possible
disable speedstep
Disable C1e
set memory (chipset) to 4-4-4-12
set CPU vcore to 1.35
Set Vdimm to 2.1

Thanks w3bbo - I really appreciate your help and will try what you suggest.

Do you think I could increase the PCI Frequency as well?

I have the bios version 614. I think the speedstep option was removed. Am I right?

Thanks again.

Good start. Setup your BIOS and you will hit 3-3.2ghz easy.

You can up the pci frequency, I have mine set to 110 which allows me a slightly higher overclock on the graphics card. Be carefull though and take it one step at a time.

It sounds like you have caught the overclocking bug!..GL

Hello All - made the changes recommended.

You can find the CPU-Z results there: http://www.perrault.eclipse.co.uk/untitled.jpg

Is everything ok? Any recommendation?

Finally i have not changed the pci express frequency as I read it ihas very little impact on performance.

Also my ideal CPU temperature is 49C and under load i'mgoing in the 56C territory is it safe?

Thanks

Yeah it's safe into the 60s although you don't want to be going too far into them if poss. With the stock cooler that's excellent.

BTW - after playing FEAR for an hour I got a warning in PCProbe - MB temperature at 45C. Is that really a problem?

BTW - dows anybody know what the Asus aacenter.exe is useful for? It is loaded on boot.

THanks

I get similar temps (and a warning). I was a bit concerned as well so I checked the Asus forums. It seems that's a normal temp but there's also a lot of threads on bad sensor readings so it could be wrong. I'm going to leave it a while and if there's any instability i'll remove the NB heatsink and stick some AS5 on.

My motherboard was at 53-56 degrees prior to cleaning it up and inserting some fans for airflow.
