I just got a cpu voltage warning on my new build. I was running valley benchmark by unigine I have run it before. I have my motherboards drivers installed on my pc and the driver message popped up saying warning cpu voltages high. My motherboard is asus sabertooth x79. I am assuming that if it were anything damaging the pc would automatically shut off but I just want some confirmation. Would this cause any damage?
When you run some synthetic CPU benchmarks, usually handed coded in assembly, the processor will enter a very tight loop and this may delay the execution of other threads ability to process average calculations if they need to fire an interrupt to poll a hardware monitoring chip-set.
Under Vista and Windows 7, and probably any later Windows OS, Interrupts can be delayed and somewhat bundled together to avoid the performance impact this may have.
As a result the average calculations, or median, or whatever it's using, gets messed up and a false voltage spike may appear.
There may be 'some truth' to the voltage spike but if it has such a short duration it is unlikely to cause any problems anyway...
