7950GX2 Only working on 1 GPU problem. Help Appreciated

[The Asgard]

BTW - I got the EVGA superclocked version so I'll try to report back on temperatures tomorrow if I've got everything setup. Got it all sitting in an Antec P180 so hopefully will be running fairly cool because I'm loving the silence .

Whats the default clock?
Would be interested to know the Max clock on that artifact free? My Inno3d was about 580/575

Hi, i have been following this thread with interest having just bought the eVGA 7950GX2 card from Ocuk. I had a look around for others who may be experiencing the same problems as you have Asgard and found some interesting posts on the eVGA forums.

It appears that one of the users on the messageboards was having a very similar problem and has found it was being caused by AOL. However another guy also found that he could reproduce the single gpu symptoms when various other programs were left running whilst benching or running 3d apps, namely, firefox, outlook etc

Heres a link to the thread where i saw this info, i believe you will need to be registered to view it.

Great find m8.

Its exactly what I was experiencing however I did a fresh install and have never run AOL, firefox, outlook. So why mine was experiencing the same problem is a mystery. Does sound a driver issue.

The card went back a couple of days ago and I'm now indecided what to do. The Vsynch problem does concern me and something I never checked but on occasions I do switch it on. For instance Prey. I asked fornowagain to check Vsynch and he told me that it did work. So who knows.

Sli can be a real bag of worms thats for sure!

Im guessing though that as it appears that a few programs could cause this issue it would not be limited to just those that he mentioned.

I must say though im pretty sure Vsync works fine on mine with prey. However i can test it for you later if you would like me to?

If you could m8. I know on my x1900 without Vsynch I would get some major tearing.

With regard to the problem. I just find it strange that nobody else has experienced the same problem. This would suggest an hardware fault.

now slightly worried,


First mistake I made was buy ther DQ6 gigabyte mobo which cant do dual pcie cards, now im wondering if ive made a mistake by buying the 7950, should i of gone to the ati 1950 instead... any opinions appreciated and sorry for hijacking a thread, it jt seems this is becoming the new 7950 thread..



thnx

Well most don't have problems. If you have bought it just have a play. Run 3D mark 06, play a few games, go into the Nvidia control panel change a few settings and then run 3D mark 06. If you get consistent FPS in 06 they your OK. I got about 55FPS in proxy dropping to 25 when in bork mode. It should be pretty apparant if you have any problems.

If it works its the best card you can buy for the money.

Asgard when you say bork mode and dropping down to 25fps im slightly unsure what you mean. When i run 06 the return to proxycon starts at around 60odd fps, however during certain parts of it it drops to around 17fps minimum for a split second. Are you suggesting that this is also the same symptoms as you are having, or are you saying in bork mode it never gets above 25fps????

And yes ill try prey when i get home.

Sorry I didn't explain myself.

When Proxy first starts in the drop ship I get 55 FPS running normally. When its in Borked mode the same scene drops to 25.

You can do the same with Fear using the performance test. Again it roughly drops by 50%.

well ive had it for 2 weeks now n no problems so far, only thing is in one of the 3dmark 06 tests it does slow down dramatically, which im unsure about although cant remember which one it is.. If it is borked as u said asgard what is the route i should take.. Ive bin playing fear fine with etc.. But im unsure...

PLus being the superclocked version its like £410 so kinda annoyed if its already gimped..

Thanks for the help..



Btw if i remember 3dmark06 scores on a conroe e6600 and superclocked evga 7950 is like 8900 and nothing is overclocked, is this normal or not very good..

thanks again..

Thing to remember is my card was probably faulty. It would suddenly start running slow and remain in this state until a reboot. If your unsure about what your cards doing download Everest and setup to log the GPU temps to an html file. Set it to log say every minute. Leave this running and after a nights worth of playing have a look at the temps. It should be easy to see load and idle temps. When mine was borked GPU1 never increased in temps from idle even under load, may be shited a couple of degree's. Remember because of the arrangement of the card one GPU will be 5-10'c hotter than the other.

Bottom line. You have had your card for 2 weeks and you was pretty happy with it until you read this thread. I suspect its working fine. I sussed mine had a problem within a couple of hours it was that obvious.

Just to wrap up my problems, I received a replacement MSI 7950gx2 today (same model as before) and it's running a lot cooler than the previous one. As a result game and 3dmark performance is much better and I no longer have the random frame rate drops like i did when one of the cores was being throttled due to overheating. It definitely looks like it was just a faulty cooler on the original one.

Great news. Now you can just enjoy the card which is what its all about.
