Do you have apply overclocking at startup activated in afterburner? If so thats prolly why.
Try reinstalling CCC but remove Afterburner before that and install it after CCC install.

I have a hd 7970 runing at stock clock and voltage but there is a option in amd overdrivr thats i dont know fir energy its like from -20% to +20% ... Do i use this to + 20 or i stay to 0 whit no overclock
post #4553 of 38704
So I just received my Sapphire 7970 today and I've had quite some problems so far.

I started off by installing the latest available driver (12.2) and tried overclocking the card by simply using the CCC to set it at 1125 / 1575 and +20%.
Unfortunately that wasn't stable for some reason because whenever I try to join a game in BF3 it immediatly hangs and tells me that the display driver has stopped working.

So I tried to install the earlier RC11 driver and do the same overclock. It seemed to be working untill artifacts started to show up and my computer completely resets itself.

Also tried upping the voltage to 1.2v but that gave me the same results.

I've tried using CCC, Trixx and Afterburner but they all gave me the same results.

Do I have a bad card? Or just a bad driver?
post #4554 of 38704
I have strange problem with that new afterburner and 12.2 pre certified drivers.

If i overclock thru CCC to 1000/1575 and run some stress test like kombustor it runs fine with powercontrol to default 0%

But if i overclcok thru AB to same clocks i get gpu clock throtthling if i dont set power control to 20% at AB settings..

Any idea what could cause that?

I need a little help, I bet in this forum somewhere but so many pages. Im looking to get a 7970 and I was looking at the HIS or the XFX but it seems Sapphire is what alot have on here. I need someone to give me a brand suggestion so I can jump on this card. Its my 1st time with ATI in years, Thanks for your input in advance

Me personally, I went with Sapphire because I had a 5870 from them and it hasn't given me the slightest bit of problems. Also, I read that Sapphire provided HDMI cable/HDMI to DP/DVI to DP adapters which I needed. I'm not say that the others don't include those, I'm just saying that they provide a bunch of adapters for only $10 more.

Normally I would have gone with the XFX brand for the lifetime warranty but I read that they are no longer giving that warranty with this series. I want to say that all of this information was taken from Newegg customer reviews.

So I'm not going to tell you that one brand is better than the other because that is personal preference and opinion. I like Sapphire because I have never had a problem with them. This may change in the future if something goes wrong rolleyes.gif

@Frojoe

Recommending a brand is not easy, but from the research I have done I would say that mosst of the reference cards will be similar.

HIS, Sapphire, MSI, Asus, etc. If you can find them for the 550 retail price, I would say you will be OK.

Some notes:

XFX double dissipation(two fans) models of the 7970 carry a lifetime warranty. It's not a bad thing to have, but I feel a good two or three year warranty is enough, considering you will likely get rid of the card by then. Also XFX does not care if you overclock, some makers say that overclocking voids the warranty.

Sapphire has plenty of accesories, plug adaptors, HDMI cable etc.

Gigabyte(this is what I have ordered) has a three year warranty, but includes no additional cables or adapters. I just liked their three fan OC version and I got it for 569.00, which was a good deal.

Diammond has a five year warranty.

Visiontek has a lifetime warranty, but I would not count on them being around to honor it smile.gif

If I had to recommend some brands, I guess Asus, XFX Double (Dissipation cards only), Sapphire, and Gigabyte.

I hope you are able to find a good card and get a good price! New egg and Amazon are not bad places to start.
post #4558 of 38704
Thanks for all that fast responses. Well for me im guessing the warranty wont matter once I rip the air cooler of it and watercool it frown.gif But good to know about the acessories. So my next question is since brand isnt too big of a problem besides like visiontek. I guess I would look at the HIS,Sapphire and the XFX but is it better to get the already OC from the factory or should I just get stock ref and do it myself? im just curious if there is better hardware on the OC 7970's?
post #4559 of 38704
Sapphire 7950 OC version has dual fan and better cooling while the standard sapphire 7950 only has 1 fan and not so good cooling. This I read from a review site somewhere.
No idea how it is with 7970 cards...

Someone else likely knows more than I about the quality difference of the factort OC versions. Some say these have better binned chips, meaning they are the cream of the pick. But with these first releases, I would guess most of these cards have nearly identical hardware.

One thing to note is XFX will allow you to install a water block without voiding your warranty, you just need to contact them first and let them know what you are planning.

If you just want a stock 7970, the HIS is probably a good choice at the moment. It's 549 at Amazon and has every possible accessory you can imagine, even a bracket to support the card in your case.
