What voltages for Asus P5Q-EM?

[TechnoCorruption]

Since adding a second set of 2x1GB ram I have been getting a few bsod's. I have previously left all voltages on auto. (except cpu 1.1v and ram 2.2v)

The system passed a 8hr prime test prior to the second set of ram going in. I have a feeling that I need to set some voltages manually, probably the northbridge. (P45/P43)

What sort of volts should I be giving it? I can select 1.2v - 1.7v.

Try 1.4v. A little excessive for some boards but wont cause any damage. If its stable then you can start to lower it. I wouldn't go above 1.45v though.

Thanks for the advice mate. Do you know if there are any other voltages that I should be taking off auto?

My last board was a P5K-E Wifi about 18 months ago and I could run everything bar cpu/nb/ram on the auto settings.

Haven't got time to write as much as I'd like... However with this board there seems to be an FSB wall (around 420-425) when the PCI-E frequency sets itself to 103 (which this board does above a certain speed). You need to put the frequency higher still than 103 (saw one guy recommend 110mhz).

You also need to turn off Static Read Control and Read Training for the RAM.

Just check all your voltages, as the P5Q range are known to set them quite high at times on auto.

I built a system based on a P5Q Pro Turbo for a friend and when left on auto the PLL voltage was showing 1.8v, which is dangerously high to be honest!!!

These were the settings on his with an E8400 at 4ghz. He had 2x2gb ram, but still these might help guide you a little...

CPU - 1.275
NB - 1.28
SB - 1.1
SB PCIE - 1.5
CPU PLL - 1.56
FSB TERM - 1.3

That's perfect, thanks very much guys.
