Best way to kill a 7950?

post #1 of 10
Thread Starter 
Overvolt? biggrin.gif

The card has ASIC 55.9%. It does 1230-40 MHz core and 1600MHz memory in game for 1.3v errr...

It has a weird issue. At stock speed it performs very bad I get 10-20FPS range in sleeping dogs High settings (forget extreme) and once I apply overclock (like 1000/1250), I get 60FPS!?
Stock speed benchmark result in unigine is 200 and 1200 overclocked to 1260/1600...

Tried 12.10, 12.11 B4 & 12.11 B7, all have the same problem mad.gif

Oh and I get gray horizontal lines as soon as I overclock on desktop mode, so I can play game fine but I have to reset clock when I am in desktop mode madsmiley.png

Do not try to kill it.

Just RMA it. And they'll send you a new card.


Unless of coarse, this is a troll thread...

Firstly, have you checked the temperatures it's running at? It may be downclocking if it is getting too hot.
The only reason I ask is that you talked about horizontal gray lines, which sound suspiciously like artifacting.
Have you tried re-seating the heatsink and making sure all the RAM chips are properly contacting the heatsink?

Max temp seen with highest overclock was 60C. Gigabyte did a good job with the cooler I have to admit!

How can they accept my RMA? Maybe they will say my computer is the problem :S

Wow at this thread. When something is wrong with a product, your RMA it. Pretty simple, really.

uninstall all overclocking tools, uninstall AMD software/drivers

Re-install drivers only, and try benchmark and games with everything just left at stock.

If you still experience issues then try in a different PC if you can, and if you still experience the same issues with it then you have a legit claim for RMA

I know when the Nvidia drivers crash on my 560Ti crash it gets stuck at 405MHz, do you monitor your clocks when in game? Your card overclock may be unstable, or too hot as said above.

I have problem when playing at stock settings (low FPS) and gray horizontal line WHATEVER the voltage is. Those lines appears only on desktop mode and the overclock is stable because I don`t crash in game and whatever by how much I drop the frequency from 1240MHz @ 1.3v to whatever frequency, I still see those gray lines appearing when game is loading between levels or while browsing when I do an action such (like scrolling).

Please follow my steps and then report back to me. Sometimes overclock software and or driver conflicts can cause the issues you are experiencing even if the clocks are at stock or appear to be stable.

In particular the latest drivers are finicky when afterburner is installed, even if it isn't even running.

Following the steps I outlined will allow you to definitely find out if it is a software or hardware issue. Right now you are just guessing
