Hye everyone..

I have a Sapphire HD 7950 dua x oc edition Gpu.. stock 925 for core & 1250 memory.. I try to clock it but it seems i got it worse... the fps im getting is lower from the stock . can anyone explain to me what actually happend. huhu

Hi there! What software are you using to OC? I suggest MSI Afterburner. Don't mess with the "Vcore" or voltage. Try increasing your core speed first in small increments, and run a stress test. When the stress test starts showing artifacts like weird colours or anything different, lower you core speed. Repeat with the memory, though you will not find much difference with a higher memory speed. Good luck!

FPS drop after overclock, probably because not enough voltage to the card.
Using AMD overdrive, increase the power limit to +20%

but i prefer Trixx, my 7950 able to reach 1050/1530 with stock voltage but +20% power limit.
