AMD FX-8320 Overclocking Itself

Hello Tom's Hardware people, it's been a while since I've posted anything because I haven't (thankfully) had any problems for a long time.

I'm running an AMD FX-8320 (the original, not the E version) on an ASUS M5A97 R2.0 mobo, Hyper 212 EVO for cooling. Everything is really stable and great, great performance in video games, etc. However, something as of late has been happening that's kind of... weird.

The native BIOS setting is to use AMD's Turbo Core technology to push my CPU from 3.5ghz up to 4.0ghz when the demand gets high. However, this pushes my temps up to about 62°C, and I'm not really comfortable with it getting that hot (although I am well aware that it can take more).

Thus, I disabled Turbo Core and manually disabled all automatic overclocking to lock my clock rates at 3.5ghz. It fits my needs just fine with no noticeable performance changes in my games and keeps my temps at a max of 53°C (amazing how 500~ mhz can cause a 9° change).

However, when I put my computer to sleep and wake it up, my clocks shoot back up!

Restarting my computer, everything goes back to how it's supposed to.

But the second I put it to sleep and wake it back up, my clocks reset to 4.0ghz. I've checked (and disabled) AI Suite as well as the Catalyst Control Center (CPU OverDrive, AMD OverDrive, etc. et. al.). I just find it strange how something, somehow, is overriding the saved BIOS overclock settings.

Any ideas? Any help would be greatly appreciated.

Thank you.

The 4 GHZ after wake up stays until I restart my computer. I don't know how to check and see if Turbo Mode was re-enabled after wake up because the settings are in the BIOS; however, the settings in ASUS AI Suite and the Catalyst Control Center remain unchanged.

Well, looking at the screenshot of HWM you posted, it shows the current speed at 1405 MHz, about as expected if you have C&Q enabled. The 4GHz was only a max. Could that have only lasted momentarily until the wake-up routing was completed and prior settings were recognized once again? Then went back to your correct settings? Run something like Prime95 or Intel Burn Test and see what the clocks go to when there is a 100% load.

My Asus motherboard has a certain problem, not exactly like yours, but it's probably related. I have an overclock to 4.5 GHz as you can see in my sig. If I put my PC to sleep, the overclock is negated after it wakes up. There is something about the BIOS where it doesn't know how to cope with the sleep mode. When it exits sleep mode, it always loads the default BIOS settings rather than what I want.

I have not found a solution for this.

Even after the wakeup is finished, it will continue to shoot up to 4 when under load. After some more testing, if I don't put the computer to sleep, the max will slowly creep up anyways. The longer I ran War Thunder, the max would go from 3512 to 3536 mhz. Looking around online, some people have the same problem on Windows 7, just in reverse, where they will over clock in BIOS then when they sleep the computer and wake it up it will go back to stock clocks (like this).

It's very perplexing to say the least and I'm considering doing a clean install of Windows.
