Q9650 and P5q Dluxe

[ntemples1]

Hi there I am getting a Q9650 to replace my E8400 on a P5q Deluxe, but I am wondering what to do about the default voltage, what should I put it on? I don't want to leave it on Auto in case it over volts, so if someone could give me a good voltage to start on I would appreciate it.

I plan on getting as near to 4Ghz as I can, fingers crossed!!!

thanks in advance

Change it back to "default" for all bios settings, right before you change chips. It won't overvolt...

Before you switch out the cpu's update to the latest bios: next when the pc is shut down for the swap, pull the cmos so everything gets reset. I feel that is the best way.

You should hit 4Ghz without tooo much bios play but you will have to do some to get it stable.

thanks guys will do, what voltage should i be aiming at to begin with?

Various refinements to this opinion. I'm only familiar with the Wolfdale, whose retail box is labeled "Max Voltage: 1.25V." So I'm only guessing the same spec applies to your quad.

The Intel web-site's specs are probably showing a range between 0.85 and 1.36+V, and as I understand it, the relevant value to compare to either the label or the range is CPU_Z readings under stress-test load.

And each individual processor has a VID.

Personally, if over-clocking, I'd see what the sensor shows under "Auto" and start with that as a base value, although one could also just cut to the chase and fix the initial value to 1.25V.

And again, my personal opinion: Your target over-clock should pay some attention to how much above 1.25V your load voltage reading shows. I'd say that a variance of +0.05V is harmless. Obviously, for whatever OC, you'll want to trim the voltage to the lowest stable value -- or just a notch above that.
