My PSU recently said goodnight and I had to replace it today. Came home from Best Buy, wired everything up, and now my clock speed won't go above 1.37 GHz. I have an AMD FX6300 hexacore processor running at 3.5 GHz stock, 4.1 GHz OC. It currently is not overclocked but even when I do, the clock speed still won't run at max speed.
Here are my specs:
CPU: AMD FX-6300 @ 3.5GHZ
GPU: ASUS R7 265 2gb
RAM: 4x4gb Kingston HyperX FURY @ 1866 MHz
PSU: Corsair CX750M (newly added as of today)
Mobo: MSI 870 Gaming
Running on a ADATA SP550 240gb SSD
Windows 10 version 1511 64bit
I searched the interwebs and most were saying to check your power saving mode ,and so I changed it to high performance with no avail. Also, as far as I know, core parking is not a part of Windows 10 so that can't be the issue either.
CPU-Z says my core speed is 1400MHz which is where the problem occurs. The multiplier is at 7 and even when I change it to 20 (~4.0GHz) the speed does not increase. Went in to BIOS and disabled AMD's Cool'n'Quiet option with no results. I've attached a screenshot that shows the problem. Right at startup, the clock speed is only at 1.33 GHz, while off on the right hand side, you can see the maximum speed is 3.5GHz.
The clock speed stays like this even under load. I launch GTA5 which will only utilize about 50% of my processor running at 3.5GHz, but it underperforms at only about 40% utilized and refuses to go any higher even with other programs open. Here is a screenshot of the system under load:
I used HWMonitor to see what was going on, and apparently it was using all six of my cores at 100%, but the task manager still says it is only using about 40% of is potential.
So the big question is: wtf is going on? I'm suspecting a hardware issue that correlated to the failed PSU but everything seems to work fine. All six cores will run at 100%, and I doubt it could be anything else since I can clearly see that the clock speed will not reach maximum speed no matter what.
Thanks for making me go in my case and check all the connections. The connections were fine, but I noticed a button on my mobo that reads "slow mode" which I had turned on to try and diagnose why my computer was constantly crashing. I made an educated guess that the PSU had failed since it wouldn't start and got a new one today. Lo and behold: I forgot to turn off slow mode after I replaced my PSU. I'm gonna go crawl into a hole and act like this never happened lol.
