I have avaible a new overclocking guide hand written by txnetcop.......From the origional Author Graysky..... ( updated and corrected by txnetcop)


Everything you ever wanted to know about OVERCLOCKING GUIDE FOR CORE2DUO and CORE2QUADs

Its large and you need to PM me with your E-Mail address and I will send it to you

Much Thanks To Ted For This....

Hi I've just requested guide.

Using Prime95

I can get my @9550 to run in Windows @ 4.0 GHz, but Crash Core 2 at 10 minutes so I've decided to run @ 3.8 GHz.
Core 2 stops after 2 1/2 hours and Core 1 stops at 8 hours. I haven't run longer than that.
Below are my settings.

3.8 ghz -

You might want to play with the voltages a bit more since you are experiencing crashes. Granted, 3.8 GHz from a 2.83 GHz CPU is a hell of a good overclock, but others have done the same and with 24 hour stability.

Update

Okay here is an update.

Messed around with a lot of settings with no real improvement until I set everything as stated above, but changed only one setting

DRAM Frequency: 969 I now have at DRAM Frequency: 1096.

Core 2 now ran though(10 Hours), but core 1 still stopped at 8 hours.

Man this takes a long time to test!

What's considded a stable OC?

Depends upon your standards. For me, at least 12 hours. I think 24 hours is pretty much the gold standard.
