7970 - DX9 flickers, low score in Valley benchmark

post #1 of 12
Thread Starter 
After getting a replacement for my old 7970 which went haywire and had problems like artifacts, flickers and crashing. I still have flicker problems in Windows and DX9 games. Any solutions?

Also, my score in the Valley benchmark is really low compared to similar systems.



Does anyone know what may be the cause of this?

Edit: I should note that I'm running a 120hz monitor. I believe that may be the cause of the problem.

First step reinstal the drivers. Then run the benchmark again and do it at least 3 times. Unigine benchmarks can be quite inconsistent as its prone to hiccups when changing scenes (can really drag down the min fps and as well as reduce the final score some what).

What CPU are you running by the way?

13.2 driver fixes dx9 flickering.
120hz, shouldnt matter.
zerocore is making the memory speed to change in desktop mode that can be one source of it.

I'm running an i7 3770k CPU @ 4.2Ghz. (Some benchmarks say 3.5Ghz, while others say 4.2Ghz. Don't really know why.) Just did a Valley benchmark with the fan @70%, here's the result:



Will upgrade to 13.2 now.

Edit: I meant cause of the flickers, not the low score, when I mentioned that I'm running a 120hz screen.

120hz isnt the reason for flickering.
3.5 vs 4.2 is how the program measure the data, some use default cpu speed as referens others take note of actual speed..

flickering can happen in desktop due to zerocore changes state inside the gpu mhz changes while you surf, etc...
However most can fix that by either flashing a new bios from the cards manufacturer if such applies to your card I dont know.
or change the input of the display from DVI to Displayport or such also, change the cable that goes into your cards input.

there can be several reasons why it happens in desktop, none related to 120hz to my knowledge.
mhz ram changes, cable port to your card, etc...

New drivers seem to have helped a bit, 70% fan speed 60c max. (Can't check the VRAM temp, won't show up anywhere.)



Would you say these are "normal" scores for my 1000 core and 1400 mem clock?

Edit: Checked the benchmark thread, I've basically got the score of 7950's / 670's..

Upgrade to the beta 6 drivers and you should gain a few hundred points. And no flickers in DX9 with beta 3 onwards.

PS. The beta 6 drivers removed my flicker problems in DX9 games, but not in Windows. But now the freezes and artifacts are back. (The same thing that happened to my "old" XFX 7970 DD card.)

I'd recommend reinstalling your os, even with driver cleaners after getting my 7950 card back from RMA i was getting weird artifacts (with 13.2b 5). After reinstalling everything fresh the artifacts went away. Might have something to do with power mode settings being left in the registry after uninstalling ati drivers, just a guess though.

Also what power supply do you have?

OS was reinstalled about 3 months ago. I've got a a 650w Corsair PSU, not sure the exact model.
