[SOLVED] My CPU is not running at full capacity.

[Agwebberley]

My CPU won't run at full capacity (36%). I have tried everything in other forums but nothing works. When I try to run a CPU heavy game my PC maxes out at 36% as if it were 100%. My Pc doesn't crash or overheat.

My Build

MotherBoard: Crosshair Formula-Z W/ the latest BIOS.

CPU: AMD FX-4130 Quad Core (Although Windows is reading it as two cores and 4 logical processors)

RAM: 32 GB DDR3

GPU: AMD Radeon R9 390

SSD: 128GB Seagate W/ my operating System on it

Hard Disks: Various hard disks pulled from many different computers

Power Supply: 550W CoolMax ZX-600

Yeah something is wrong with either your CPU, motherboard or both. It should have had no problem accepting those settings. Did you buy the board new? It may have some burnt VRMs, which is not something you can fix. Or there is some issue with the CPU which is only repairable by replacing it.

The CPU was used I have no idea if it was well taken care of (It was a little to cheap to be true). The motherboard was also used, i got it from a friend who was upgrading but he kept it in perfect condition.

He may have but that doesn't mean he didn't damage it by accident or over time. What CPU did he have in it?

I agree the more likely culprit may be the questionable used CPU.

He had an FX-8150 I think (I know it started with an 8)

I have his old CPU but it had overheating problems...

 

[Agwebberley]

But maybe that processor underclocked would be better than this.

If his old CPU had overheating problems (125w) 8 core that very much could have been VRM failure. CPU's don't just have "overheating problems" it has a problem because its being improperly cooled, or the VRMs are not being cooled or are failing.

Everything you are seeing tells me your motherboard is failing.

The CPU requires a water cooler which I don't have. If I underclock it it should run fine. It is just insufficient cooling. I hope... What is a VRM?

 

[Karadjgne]

Cpu does not require water cooling. The only FX cpus that really do/did are the 2x 9 series, the 9370 and 9590 as their output of well over 200w is more than any sane aircooler can responsibly handle.

An 8350 OC to @ 4.5GHz can be cooled by a CM hyper212 evo. If your buddy had overheating issues, it was likely due to miserable cooling and/or miserable airflow in the case.

100% that CPU does NOT require a water cooler, in addition had the prior owner been using a water cooler and the system did not have a fan cooling the VRMs or good enough airflow in the case to cool them off, thats yet another reason they could have burned out.

Again if this board had problems with another CPU, and now the CPU you bought, whats the common denominator here? Your Cpu is literally behaving as if the VRMs can't provide enough voltage.

VRMs are the parts of the board that take the 12v your PSU supplies and brings it down to the voltage your cpu needs (less than 1.5v). They are around the outside edge of your CPU socket, in your case under heatsinks.

I hate to agree. But you seem to be right. But that s an expensive fix that I currently don't have the money for... Thank you all again for all your help.

Sorry it worked out like this.

My suggestion would be to save for a new platform (ie AMD Ryzen). FX is very much dead and not worth spending money on.

Ya, Your right, I was just given the motherboard.
