Hey guys . This is actually my first post here and I could really use some help. I recently bought a new rig to play games like Max Payne 3 and The Witcher 2. And at first I didn't overclock my GPU at all. But people were saying how great of an overclocker the 7950 is and I got curious. My rig came with a Corsair TX650W PSU, wich the guy told me, was enough for a single 7950. So I went to AMD Overdrive and manually overclocked my GPU. Without tweaking my voltage I put the GPU clock up to 1020 Mhz (850 default) the Memory Clock to 1575 Max ( 1250 def ) and the power slider at the bottom was set to 0 so I set it to 20% max. Bottom line. Both my PSU and my GPU went to the crapper. My PC suddently shut down and I couldn't turn it back up. I don't know if my PSU couldn't handle my overclock , but both these parts literally broke. My luck was that both of them were still under warranty, otherwise I don't know what I could have done. Now I got another 7950 but this time I bought myself a 750 Sentey PSU 80+ and I turned to the overclock down a bit to 925/1375/20%. Could any of you guys please tell me if it's safe, or if I should let the card run at stock speeds anyway? The performance gain was so great that I really don't want to go back to stock speeds
I would really apreciate any kind of help!
Thanks a LOT!!!!
They didn't increase the voltage while using AMD Overdrive at all. He says that voltage tweaking is another thing and it demmands a lot more skill and patience, because it's way more risky. He went with 100/1500/20% without any problems.
