Diamon AMD Radeon HD 7770

[hustla2]

Hey guys,

I recently upgraded my graphics card.My old one was a AMD Radeon HD 6570 and now the new one is a Diamon AMD Radeon HD 7770 Ghz Edition.I've done everything correctly(Installing the card+Installing the latest driver from the website),but whenever I start any game up,it would play for about 3-4 seconds,freeze and crash the game.Sometimes it even restarts the computer.

My PC Specs are:

Windows 7 Ultimate(64 bit)
Diamon AMD Radeon HD 7770
4GB Ram
AMD Athlon X2 250 3.0Ghz Processor
500W Power supply(Yes it does have a 6 pin cable for the graphics card)

Any help would be appreciated.

Thanks.

I am not sure about psu quality. Never heard of it. Both your mobo and gpu is fine. You can try with decent psu. Can you check your system with your friend's psu you checked before?

Nevermind guys,it finally worked.This time I downloaded the driver with a BIOS update,but I still got a problem.Switching from the 6570 to the 7770 wasn't really a difference for me...I mean,I get the same amount of FPS and I still can't really record with fraps without lag.Maybe it's because of my dual core processor that my card isn't giving it's 100%? Do I need a better power supply or a quad or more core processor?

By the way,thanks for helping me.

If it can run then the PSU can give it enough power. As for the processor that's more likely the issue.

Good for you, you solve the problem.

You cpu is bottlenecking your gpu. Its not giving its 100%. To check how many % of gpu you are using, use GPU-Z soft.

But non-cpu intensive games will give you full performance boost of 7770 like Dirt3/Alan Wake/BF3 in SP.

What is your mobo? You can upgrade to a phenom ii x4 cpu which will not bottleneck your gpu and will be very good for you.
