R9 290X - 2D memory clock causing flickering? Can't change low clocks!

post #1 of 5
Thread Starter 
So I just got a new PowerColor PCS+ R9 290X yesterday -immediately I noticed was when the clocks are down in 2D mode, like on the desktop or in a browser, etc. There is a nearly-constant flickering of horizontal lines. They vary in height by a few pixels, from like 1 to 4px or more I'd guess, and they are about 1/8 the width of my 1080p screen, and occur systematically in 2 or 3 "columns" sporadically across my screen.

I tried hooking the computer up to my TV with an HDMI, as I was using DVIs with my two desktop monitors - same thing. So it doesn't appear to be the displays or the display method.

And of course, it goes away during any 3D applications that cause the clocks to jump up to the 3D/max settings. I can game just fine with the card, there doesn't seem to be anything wrong when it's doing what it's supposed to do, and the temperatures are impressively cool - 60's while gaming!

I remember having a different flicker issue a few years ago with my 5850, and I solved it by editing the profile.xml file for CCC, and raising the 2D clocks to like triple what they were set at, and voila! I tried to do that again, but with CCC 14.4 (current as of this post), the profile.xml seems to "self-heal" and rewrite the memory clock back down to 150mhz, which I believe to be the culprit, from what I can gather from other forums/threads. This occurs even with OverDrive enabled in CCC. I also tried the latest beta driver, and rolling back to 13.12, and the issue continues to occur - I cleaned out the driver with DDU in the process each time.

So I'm wondering... does anyone know of a solution for this, or have any additional ideas? Should I just RMA the card, and hope the new one doesn't do it? I have a feeling it may not be a defect, but then I can't find anyone else experiencing this same exact issue with this card either, but if I get a new one back and it's still doing it... well, then I'll probably be right back here, I figure. This isn't something I am willing to live with, as I work with 2D desktop apps for a living...

Thoughts?

Hey!

I have the same problem.

Did you RMA your card?

If I overclock it using ASUS Gpu Tool it's fine.

Best regards,
Klaus

Honestly, I ended up selling the card shortly after and getting a GTX 970 - all issues resolved that way, ha. It's been long enough now that I can't remember exactly what I did, but I was plagued with several issues with that card that made me get out of it as quickly as possible - plus the 970 made like 40% of the heat that the 290X did.

Just edit your bios to add 25MV voltage in DPM1.
Everything explained there.

For some reason the default 290 memory setting are full speed except for the lowest power level. So the second lowest power level is only slightly more voltage at full memory clock. I think that is the main reason why many 290 cards hat/have problems with black screens and stuff you see on your card when at idle mode.

To fix this you can just bump up the voltage offset or use a simple bios edit.

Basically you have 3 possible memory clock values and can assign each of the 8 power levels to one of the memory clocks.
All you have to do is to set the lower power levels to lower memory clock speeds.

This is how the setting locks for my undervolted 290:

And here are all the infos and tools you need to do it yourself:
