Stress tests on R9 280X lead to clock drops.
Stress tests on R9 280X lead to clock drops.
Hey guys,
I am currently playing around with GPU overclocking using MSI Afterburner.
While stresstesting with Geeks3D FurMark v1.20.4.0 I noticed periodic coreclock drops.
My System:
GPU: Powercolor R9 280X with a basecoreclock of 1030MHz and a basememoryclock of 1500MHz
CPU: AMD FX-8350 not overclocked
Mainboard: ASUS M5A97 R2.0
RAM: 8GB
OS: Windows 10
What could be causing the drops and is it serious? I've not tested the stability in games yet.

The coreclockspeed in the screenshot was 1150MHz
Increase the fan speed further and apply more stress. I had two 7970 cards (identical to yours) running at 1050/1550 for many years without any problems.
I adjusted the fan speed settings in MSI Afterburner.
70°C corresponds to 70%, 80°C to 80%, and above 90°C to 100%.
Should I modify the curve?
Update:
I increased the curve at 80°C to 90%.
Currently at 1130MHz with no drops after 10 minutes. It looks like the fix is straightforward.
Thank you
