Idle cpu voltage high

[nathan_r_nelson123]

I have started over clocking my cpu running aida 64 stress test. I ran previous test before over clocking to ensure default stability and everything passed. I have set the voltage to adaptive @ 1.25v with a multiplier of 45. Now when I opened up cpu z the cpu voltage at idle was at 1.25 fluxuating up but never below 1.25v. I thought adaptive allowed it to fall when the cpu wasn't under load. Am I wrong?

After noticing this i went back to the bios and set everything to default and no my cpu voltage won't drop below 1.2v even set to auto in the bios.

When I ran my first stress test with everything at base clock the cpu voltage would drop to .9.

I don't understand why my cpu voltage won't drop at idle.

My system specs are

I7 5820k cpu

Corsair H100i cpu cooler

Asus-pro mobo

Corsair Hx850i PSU

Kingston Hyperx predator 4x4gb

Asus gtx 970

Could xmp enabled cause my voltage to stay peaked?

Dont do stress tests with adaptive voltage on, it can make it spike and get high voltage which isn't good for the CPU. Always put it to manual. Try resetting the whole BIOS back to default and see if that works.

Thank you for a reply was afraid no one was going to help

I will try that asap and get back to yah

That is fairly normal. Nothing really to worry about. Also, cpu-z, is not that great for monitoring system voltages. I find hwmonitor much better for that.

benchmarks like aida64 dont do that. Its only prime 95 that you really have to worry about. Haswell cpu's will overvolt in a program like prime95 regardless of settings

Really? I was informed that it was all stress tests.

So 1.2 v at idle is normal?

yes, its really only prime 95 that causes serious issues. Specifically the small FFTs test.

That's not good because as soon as I got this CPU I stress tested it with P95 with auto on...

im at 1.29 at idle. VID usually does not vary at all even when intels power saving features are turned on.

It would likely take many hours of running the stress test to do any real damage to the cpu realistically so you should not have to worry. Intel cpu's have allot of safeguards that prevent major damage. Just stick with other stress testing tools in the future. I like to use asus real bench and aida 64 for my stability testing.

Yeah I have aida 64 and realbench. Is there a way to have realbench stress for more than 8 hours?

I have looked at Ai suite as well but don't trust it had my CPU doing 4.6GHz and it was not stable pulling 1.35v

realbench has a checkmark to run indefinitely right next to the number of times you want to run it. At least mine has that. Not sure if it is different in a newer version if there is one.
