Problems/flickering with 5850?

post #1 of 6
Thread Starter 
Hi guys!

I have this graphics card since like 8 months now (Powercolor 5850 PCS+ 1gb) but just got a second asus vh242h monitor (so now I'm dual screen).

Unfortunately I encountered a lot of problems with that setup (flickering while watching youtube/flash videos) and immediate crash(windows recovers or BSOD) as soon as I watch or run 2-3 videos at the same time! Also, I absolutely CANNOT play sc2 AND watch a video (or just listen to it) at the same time, it crashes...

I ran furmark at extreme burning mode in 1080p (high details) and it was fine for 12 hours, same thing with prime95 for the cpu. But for an unknown reason, I keep getting crashes related to graphics card drivers/hardware (not sure if it's true though) according to windows. Ram is also fine, just coming from a memtest exam. Here's my specs

i7 930 stock
sabertooth x58
g.skill 3x2 gb ddr3-1600
corsair tx-750 watts
2x500gb raid0 7200.12 HDD.

I tried reinstalling old/new drivers, I still get that weird issue . After a quick google search, it seemed to be related to the graphics card downclocking and undervolting, I tried disabling powerplay (it bsod in sc2 or any full screen game), I also tried amd gpu clock tool to keep the clocks at their stock positions, but I keep getting flickering issues. I'm pretty sure the graphics card is ok as it works wonder on one screen (can run 10 videos at the same time + sc2 no problems) but as soon as I add that second monitor, it gets impossible to do anything video intensive. I heard about that flashing method, but I'm not even sure it'll work, and I do not want to destroy my card nor void my warranty for trying. Anybody else have this problem? Anybody else fixed it? If really needed, I'll film a video about the flickering and when it happens etc...

I've been lurking for quite some time (as you can see), now I hope I can receive any help from you, while learning at the same time, thanks a lot!

p.s Sorry for my bad english grammar, it's not my native language :S

Ah, yes. I had this problem. There is a bug with AMD's Overdrive Utility when running two or more screens. Go into your catalyst drivers and turn off AMD Overdrive and see how that works. That also messes up 5.1 surround sound when you output sound from your HDMI port, weird huh? Anyways give that a shot and let me know how it goes. Otherwise dont try to manually undervolt/clock anything, it wont help and neither will overclocking. It's more a software glitch than it is being able to trick it with hardware.

You need to disable hardware acceleration. Start a You Tube video and pause it immediately so that you don't crash, then right click on the video. Go to Settings and uncheck Enable hardware acceleration. That fixed it for me....

Wow CamberWell, it seems to work for now (although there is still a slight stutter when I open the video and when I close it) it doesn't crash anymore, thank you very much guys!

On your system tray there's the catalyst suite icon, that red sphere with some silver stuff around it (lol sorry for butchering the logo description haha) it's in there, so right click that icon and click on "catalyst control center..." and then it's under the performance tab on the left. There'll be a checkbox for "AMD Overdrive"
