NB(Northbridge) and SB(Southbridge) voltages going crazy Tags: Asus Motherboards Last response: September 29, 2009 12:56 PM in Motherboards Share Retro Alfa September 28, 2009 3:34:02 PM Ok,this is the problem. I have pc probe II,and almost every time I start CPU-Z, SB and NB voltages going crazy for a sec or two,and sometimes just randomly goes up and I have to restart my PC. I have O.C my PC from 2.5 GHz to 3.0 GHz stable, prime95 3 hours,and all my voltages are set to manual,so how can they spike from time to time. Loadline calibration is disabled. With the stock values I have the same problem. Is there any other software that measures voltages on a motherboard ?
