OCing a 7970

[baz2963]

Hi,

I'm new to overclocking a card so pls bear with me.

Long story, but basically I had an Asus matrix 7970 which at stock was 1100/1650. I now have a sapphire vapor 7970 1050/1500.

I preferred the results I was getting with the matrix, so if I just up the core and Mem in catalyst will it likely end up being the same card as the asus ? And what repercussions should I expect I.e voiding warranty etc ?

Thanks

Chances are it should hit the same clocks, you would be very unlucky for it not too, easiest way is to use CCC like you mentioned.

I doubt you will get any repercussions, no one can tell you overclocked your card using software at all as it's done through software, there is no physical evidence unless you hard mod the card.

Or overvolt and burn the thing out lol.

Still staying at stock and upping the core+memory wont harm anything, the temps may rise a bit but it shouldnt damage nothing and add a few fps to games

Thanks for that !

I've copied the Mem and clock for the matrix and my card won't go over 60oC, so I guess happy days !.

It begs the question why do people buy the more expensive cards !?

You'd probably struggle to physically damage it with the volt limits in place tbh.

People buy more expensive cards for heavy overclocking, something like 8 of the top 10 3dmark11 scores are done with lightnings...

1200/1600 and 20% power in ccc and give haven benchmark a test, you should be fine but otherwise give after burn a go and increase the voltage slightly.
