Resetting a GPU to stock clocks without software

TheOGJey · April 26, 2015

CPU: AMD fx 6300 black edition

Motherboard: Gigabyte GA-970A-UD3P
RAM: 8 gbs 1600 mhz corsair ballistix sport ddr3 (2x4 gbs), 16 gbs 1866 mhz kingston hyperX fury ddr3 (2x8 gbs)
HDD: Seagate Barracuda 1 TB
PSU: EVGA 500 watt 80 plus certified
CPU cooler: cooler master hyper 212 evo

GPU: Sapphire Radeon r9 270 Dual-X with boost and OC

So I bought a new PSU off of amazon; A Corsair CS550M. I installed it right after overlocking my GPU in Catalyst Control Center. I noticed that whenever I plugged the GPU into the power supply, the power supply would short out and not work. When the GPU was not plugged in, it turned on fine. So I then reinstalled my old EVGA PSU and the same thing occurred. I have a feeling the card was either fried by the Corsair PSU (meaning the PSU was faulty) or that the two PSU's failsafe triggers and does not turn on the system when the graphics card pulls too much wattage. Because I have absolutely no way to boot the system with the GPU, I have no visual. I cannot go into CCC and undo the overclock. Is there any way I can return the GPU to it's stock clock speeds? And if you think it's not the overclock that's the problem, do you think the card is fried? Thanks.

Welcome to the Forum.

That means you probably have a bad card or power supply. GPU is at stock clocks on boot anyway.

RMA the card?

CCC overclock only apply after you boot into window, you can disable it in Safe Mode but since you can't even POST mean something wrong with the card.
