So I got the Sapphire Radeon HD 7950 Boost with 925MHz GPU, 1250 Memory.... I really want to overclock it, but it's my first time overclocking a PC.... I've got the stock fans and stuff, so I don't now how far I can, and if I need to add more power... I've got a 500Watt PSU, Intel Core i5 4670K and my motherboard is the MSi G43-Z87....


Does someone have some experience with overclocking on this GPU?? I heard the performance could increase ALOT....

It all depends on the quality of the chip you get. After you have tested your card at stock speeds you can keep increasing clocks in 50 mhz steps till you get artifacts, freezes and crashes. max out power control to +20%. some HD 7950 cards can do 1.1 Ghz at stock voltage. once your overclock is not stable increase voltage in 0.05v increments and repeat till you achieve the desired clocks or hit the max stable clocks for your chip. monitor core and VRM temps using gpu-z or hwinfo32. core temps below 70c and VRM temps below 90c are safe. Heaven 3.0, 3DMark 11, BF3, Crysis 3 can be used for stability testing.

Use the Tri-XX software included in the Sapphire drivers for overclocking.

When I overclock both the GPU speed and Memory by 50Mhz, the temperature of my GPU is pretty fast over the 70'c.... Do I need to turn up the fans???

Oh and I'm talking about CCC temps...

I would only starting about temps when it's in 88c to 95c some people say 70c to super safe that's why I said 70c but I let mine gpu gets 75c to 80c depending on the game and it's' safe because i have been doing this for over 2 years now with no problem

Yup, I tried 73C today and I saw ALOT of artifacts... Guess overclocking is just not for me... :(
