Overclocking leads to underclocking

I have a R7 265, running latest drivers. Whenever I try to overclock the card, even slightly, with 5 MHz increase, it severely underclocks (both Memory and Core clock) to 150 Mhz; stock is 925 MHz Core and 1400 MHz Memory.

Re: Overclocking leads to underclocking

Roll back a driver or 2 might be an idea. I am on the 18.2.1 driver & stepsons R7360OC same driver. Are you using any 3rd party software like Msi Afterburner, Rivatuner anything like that idea would be uninstall all that junk. With wattman you should be able to control how you bump it. I only run voltage bumped & increased fan profile I could suggest run it like that before giving it an OC is it. Is your card the proper OC card hard to say a bit more info may be handy of your build could be PSU related to.

Re: Overclocking leads to underclocking

I tried using MSI Afterburner, and I discovered this issue, but with AMD Center built-in OverDrive it's the same. It was the same on 18.2.1 driver. Before, I was using 17.. something driver version and it was overclocked without a problem.

Re: Overclocking leads to underclocking

Dont use afterburner its probly part of the cause. Do not ever run 3rd party software with AMD products will cause issues.

Re: Overclocking leads to underclocking

It's a garbage 400w power supply, but that's not your problem. Try an older driver set using the Clean Install AMD Graphics Drivers​ method.
