I am wondering what the safe northbridge voltages are on my board?

He talking about the nb, not the southbridge. I say 1.65 should be your max nb voltage if temps stay under 50C

Doh, my bad. I need to pay more attention. For the north bridge, I try not to go above 1.4v. 1.5v is alright if you have good enough cooling for it. Raising the north bridge voltage isn't really necessary unless you're running a high fsb, but then again I'm not too familiar with AMD setups.

Lemans, I think anything above stock (1.12volts) is probably not safe. If you have decent airflow in your case and if your chipset is actively cooled then I make the changes if they are needed but use caution. Just pay attention to the temperatures.

Good luck

Thats waaay too low. Im running mine at 1.47 now. My cooling is an HR-05. Works very well.

Refresh, according to the manual that is what is stated as the "stock" voltage. What are your temperatures at 1.47volts with the TR-HR-05? Do you have a fan on it? If so what speed is it running at ect?

Stock is 1.29v. I get about 28C with the HR-05. I can go as high as I want as long as the temps are under 50C. I have an 80MM yate loon at low speed on it.

Shawn, since your on a p35 chipset I'm not sure if the same applies for the 790 chipset in regards to heat, cooling ect.
