Sabertooth 990FX R2.0 Northbridge Help

post #1 of 2
Thread Starter 
I hear that OC'ing the NB will improve the performance of your memory and also the whole system. I have some questions though.

How much voltage can you give the NB safely?

Is there a way to monitor NB temps, and what is a safe temp?

How to test for stability, and benchmarking?

My rig is in my sig.

OCing the NB does make a big performance difference. For Deneb and Thuban, keeping it below 1.4v is best. I've heard the same for Vishera, but I'm not positive if that's true. If you use HWmonitor, I believe the northbridge is named "mainboard" or similar in the temp list for your motherboard. I personally use Prime95 for my main stress test.

Some other threads that might have useful information for you:

What are YOUR 990FX northbridge Temps?

Note: the voltage you want to change is the one labeled "CPU NB" or similar, which is part of the CPU, not the other NB one.
