R280 automatically underclocking

[Funny_Story]

I have owned my Sapphire R9 280 for about 3 months, and I've never had an issue with it until the past couple of weeks. I noticed significant FPS drops in both CS:GO and BF4. I even lowered the settings on both games, and I'm still having issues. Today, I opened MSI Afterburner, and noticed the Core Clock was jumping around from 940MHz (default) to 500MHz, and getting stuck at 500MHz for the most part. I have attached a log file from MSI Afterburner that recorded a round of CS:GO deathmatch on Inferno. If you guys need any more information, let me know, I'll happily answer.

 

NOTE: I have tried the following:

-Overclocking

-Turning up fan speeds (caused minor temporary improvements, but went back to the way it was after about 30 seconds)

-Updating drivers

-Restarting (several times)

-Setting afterburner to unofficial overclocking without powertune support

-Retting CMOS

-Uninstalling recently installed programs

-Reinstalling/Updating Afterburner

-Completely uninstalling then reinstalling drivers

 

Also, I'm fairly new to these forums. If I'm posting in the wrong section, please let me know. I'll move if needed.

Your GPU is maxing at 54c. Sounds like a driver issue. Even though you updated them. Maybe even power saving settings.

Yeah, it does that. Powertune is a bastard.

In afterburner you can set it to unofficial overclocking without Powertune support and it will stop the clocks dropping (that's what I did).

Also make sure your temps weren't going crazy or something.

I just tried that after posting this, but it didn't change anything. It's still at 500MHz.

Right. Try completely uninstalling Afterburner and reinstalling it. Failing that, do a complete uninstall of the Catalyst drivers and use Display Driver Uninstaller in safe mode, reinstall drivers and try Afterburner again.

Try disabling Flash hardware acceleration and increase board power limit.

FIXED

 

It turns out all this mess was something stupid on my part. I used to use Afterburner to record videos, and I had "insert" set as my start recording hotkey. I recently changed my push-to-talk key in Teamspeak to "insert", and hadn't realized I was recording. After I disabled the hotkey, everything went to normal while gaming, but it's jumping from 500MHz to 850MHz while idle. I'm guessing it's a power saving feature. As long as it works during gaming, I'm hoping I'm fine. (Don't tell me I need to fix something. I tried for hours today already )
