FX8350 Throttling m5a99x evo 32.0

Hi all.

I've been working on trying to get my fx8350 to 5ghz. I installed a thermaltake water 2.0 extreme on friday and was working away at finding stable settings.

Yesterday morning I noticed that my CPUs were throttling and I have no idea why.
The power settings in BIOS are all disabled, HPC is set to Enabled.
I've tried windows power settings cooling policy both passive and active.
I also tried the amd overdrive trick of turning turbo on and off.
I've tried the tweaker.exe utility with HPC=0 and HPC=1 (toggled it on purpose)
I've moved my TPU switch on and then off again.


I really don't have any idea why this is happening and its driving me nuts. It wasn't happening before...

As for VRM thermals I'm not sure of their temperatures, but considering it wasn't doing this before I would doubt its that. I've had a dual window fan blowing 40F air directly onto the board and the heatsinks are barely even warm when I touch them.

The max socket temp has been 64C and I've seen the throttling start even before then.

The only thing I can remember changing was installing AMD Overdrive to check out its ability to change ram timings without rebooting. I've uninstalled it and reinstalled it multiple times trying to toggle settings in it thinking something maybe got stuck to a setting.


Could a power supply do this? I'm at a loss for what's going on.

Thanks in advance

May I ask what PSU that you are using? Also what volts are you pushing into the CPU? Most PSU's will trip if to much is pushed threw it, or have a nice fire show. I would check in bios and see if there is anything to do with throttling. 64C it shouldn't throttle yet, but the mobo might be tring to protect it. The max temp on that CPU is 62C. I'd try updating the bios if you havn't.

My PSU is a coolermaster 600i. It may be inadequate. I posted the voltage charts wondering if anything on them looks suspicious to others. From my research everything looks to be in line with whats required but I don't know if that necessarily means its delivering the power correctly.

I've pushed the core to 70C where throttling takes place, the socket starts to throttle around 75. Now that i'm on air cooling I'm not getting close to those values but I'm throttling way before them. I can put my hand on the vrm heatsinks and they aren't even warm, sometimes they are still cold from that super cool area i'm delivering.

I'm trying to find a more robust power supply that will work for this without spending a crap ton of money.
