Please help, FX 8120 dropping clock, don't know enough to understand problem

post #1 of 56
Thread Starter 
Hello, this is my first post here, i desperately need help

My AMD FX 8120 for as long as I've had it will change it's clock back and forth between it's set clock and 1.4 ghz. It only does this when it's under a load. I've disabled cool n quiet in the BIOS, I even just recently upgraded from a 430W corsair PSU to a 600W and I don't have the heart to tell my family the PSU they just got me for $75 isn't helping the problem at all. Is there any way to fix this? I've googled the problem many times before and I can't fix it. Please help!

...List your full computer specs. It's most likely throttling, what kind of cooling do you have?

On the cooling, I've never used amd OD to actually overclock my CPU, but just to watch the temps and clock, and it stays at like 30 or below when it's running normally, but when the clock drops, the temperature appears to go up to 40-42 celcius.

I can't really be sure as I don't exactly remember whats usually inside AMD BIOS but I think there is a lot more options that could be at fault, someone will probably have more infos on this but if I was you I'd look around for unwanted power saving configuration in there.

I once went through and turned off everything remotely related to power saving I could find, and I'm not familiar but does AMD turbo core have something to do with this?

The options you want to disable will be Cool&Quiet/ C!E/C6 / EPU/ Turbo / APM and enable HPC,. I would then put it back to stock clocks and test it. Use Hwmonitor free to check temps and volts whilr under load with P95 blend or whatever your stability test of choice is. What we want to see are socket and package temps under load to verify that your 120 AIO cooler is enough to cool one of these.

Yep, and in windows set your power options to High Performance instead of Balanced or Power Saving.

The M5A97 LE R2.0 has no heatsinks on the vrms. Thats going to be a problem with the FX-8120 when upping the clock. Put a fan blowing on the VRMs and a fan on the backside of the mobo in the socket and vrm area.

You were pushing the 430W close to its limits. The upgrade to the 600W was a good decision, except that the CX600 regularly goes on sale for $59 or less after rebate.

I've already done that, and thank you all for your help so far. I will make the changes in the BIOS as soon as i get home.

I've had this problem with my Asrock 970 extreme 4 and 8120. Even at stock clocks it would clock back at load. My problem was that the vrm's would get to hot, because i have watercooling. So there was no airflow through the vrm heatsink. I ended up buying a 990fx r2.0 sabertooth. and now its @4.6ghz without problems. So try to put a fan on it.
