How much of a OC to achieve 580

post #1 of 6
Thread Starter 
How much of a OC do I need to have to achieve 580 performance? I am currently at 880/1375 on a flashed 6950.

Depends on the game and settings - in most cases the GTX 580 is 20+% faster, in some games its as much as 49% (Dirt 2) - just overclock yours as much as it will go, and enjoy having one of the top graphics cards out today When it all comes down to it, its about user experience that matters the most

Hmmm after you get the AMD 6950 to unlock to AMD 6970 by bios flash that isn't enough over clock for you? That's actually already a great over clock.

The 6970 has a 6+8 power and the memory chips are rated for 6Ghz. The AMD 6950 has two 6 pin connectors rated 5Ghz memory chips. So going further with over clock much beyond that is pretty difficult without burning or bricking your AMD 6950. Each card mileage will vary though if you get lucky with better binned vram but someone who's tried might have some suggestions or experiences they'd like to share.

Though you won't reach an over clocked GTX 580 performance you can reach stock performance by buying the AMD 6970 and over clocking it.

Obviously, if you got the cash and performance is more important to you than getting better value for you dollar you could just buy the GTX 580 and reach those speeds and beyond with an OC. *wink*

If I were you I'd be happy your getting a huge over clock with an inexpensive card to the performance level of a card higher to AMD 6970 and call it a great great day. I'm assuming if money is the issue you might not want to play with fire at risk of pushing it to far and losing it.

Hey, found this thread just below yours if you haven't run across it somone over clocking their AMD 6950. Non-ref 6950 2GB 800/1250 vs 990/1500 in furmark benches

You'll benifit from reading his trials and answers your questions from this thread.

You'd have to get to 1Ghz before it equals a GTX 580.

But you can get GTX 480 performance after you flash. It's only 15% less.
