Driver dies and then comes back to life

GaziPaji · Mar 28, 2013

Hi,
I have a sapphire HD 7950, 810mhz version. From what I read in the forums, people are getting good fps and clockspeeds when overclocking a 7950. but whenever I try overclocking mine even at 1000mhz, it crashes soon after starting benchmarking. I have the latest beta drivers installed and my CPU is i7-3770K at 3.5ghz.

some cards will over clock better then others...have you got any stable overclocks above 810mhz? if so how high....also have you tried bumping up the GPU's voltage to help stablize at higher clocks?

I would suggest going back to the last set of stable drivers, Beta drivers are not guaranteed to be bug free. I would also suggest installing a graphic tool like evga precision so you can monitor the card's temps.

Yeah, check everything that guys did. Core clock, mem clock, voltage. You must bump voltage when going 25% up, it's you must to make it stable.

I've last had it stable at 950mhz, don't accurately remember the voltages but it was a bit higher than the stock voltages. Will try the driver roll back to previous one. I use trixx and catalyst that came with the cards.

GaziPaji :

yeah roll back the drivers and then try a bump to 1000mhz...just be aware you may never hit it. if it is still unstable try a little more voltage as long as your temp are ok.

So you can clock a 810mhz card to 950mhz stable, but 1000mhz doesn't work?

Dr, my arm hurts when I put it up like this. Then, don't put it up like this.

Moral is, don't overclock to a 1000. Just because others get that, doesn't mean you will, and there is no expectation that you should.

sad but true....i will cross my fingers for you though!

GaziPaji · Mar 30, 2013

Tried the driver roll back and everything, but this card would just not go over 950mhz. Too bad I can't get a refund for poor overclocking

Thanks for your help guyz

Thanks for the help guyz.

any time. be sure to pass on the solution love!

If you want a more powerful card, buy one. Overclocking is not a right. lol.
