Wrong voltages and huge drops

[Shawn]

My FX 8350 has been showing huge voltage drops from around 1.5 to 1.0 which causes the clock speeds to drop to around 1 GHz. I have a Corsair GS700 PSU (700 watts) and I have a GTX Matrix 580 not overclocked and also about 5 hard drives and an ssd. I'm wondering if it's my motherboard doing this or not since my graphics card doesn't seem to be affected. I just noticed all this when I was doing some overclocking and testing. Mty dad has almost the same computewr but a 600watt corsair psu and a 990fxa-ud5 motherboard with a 650 ti. When I monitor his it also does the same thing so could it just be something toi do with my houses power? We're both using surge protectors and no other electronics show any signs similar and we've never had a power surge, failure or anything go wrong since its not a very old house. Any help would be greatly appreciated! Thanks!

Dropping voltages and clock speeds are usually power saving features (AMD Cool'n'quiet). Try disabling that and see if that's it. If it's that, then it 100% OK. What is the voltage set in the BIOS?

[Hirad123]

Does the voltage drop at idle or under load? It's normal as stated above if this is happening at idle because it's a power/temperature saving feature. It should turbo back up under sufficient load.

It's only happening during load

And also.. All power saving settings are off

Your voltages shouldn't be that high to begin with. My 8150 tops at around 1.42V. It has never went higher.

I've had the same problem when I overclocked my fx 8350 a few days ago.

Are you sure all your power saving settings are switched to off 'in the correct way'?

Because, there was this setting called 'CPU unlock' on my mobo, which I thought had to be enabled in order for my CPU to be OC'ed, but it seemed that this had to be disabled to OC my CPU. Very strange.. (Gigabyte 990fxa-ud3 mobo btw).

I would check some guides and reviews about OCing with your specific mobo, because settings really matter.

Also, I had my CPU underclocking itself, even with the right settings, lowering his voltages which caused to lower freqencies when clocked at 5 ghz with 1.55 vcore. So I think that was because of an instable OC which produced to much heat. Guess that's the limit for my watercooler ;).

I dont know about amd but go check everything in the bios for power saving features

I did mess the CPU unlock feature, it turns out it's for unlocking extra cores so I just disabled that but other than that I even tried the setting in voltages to stablize my voltage but it didn't help.. Maybe I'll double check them in the bios but they shouldn't be that far off, like how the 12V one isn't even close and same with like all the voltages.
