Over Voltage Problem
Over Voltage Problem
Initially
My MOBO is G-45 Gaming
My CPU is 4670K
I set the voltage to 1.15 for 4,0 Ghz (trying to find the lowest voltage for this speed)
Then I ran prime95. I checked my voltage on cpu-z and aida64 and I was surprised—they showed my voltage as 1.23.
I also ran intel burn test and my voltage came back at 1.22
I ran aida64 and my voltage stayed at 1.15 (as I set) and it didn’t crash.
Why did prime95 and intel burn test increase my voltage?
Are these tests harmful for my CPU?
Should I use them for stability testing on Haswell?
My English is bad. Sorry for the grammar mistakes.
Do you have load line calibration enabled? That would raise the voltage when under load. I’d steer clear of prime 95. It’s secure to operate on a CPU running at normal speed and voltage, and likely safe on a dual-core unit. However, I wouldn’t run it on an overclocked AVX-capable CPU with four or more cores. I think that cost me one 5820K.

It’s secure to operate on a CPU running at normal speed and voltage, and likely safe on a dual-core unit. However, I wouldn’t recommend it for an overclocked AVX-capable CPU with four or more cores. I think it already saved me the cost of a 5820K.
