Gigabyte HD7950 3Gb Windforce - Desktop/web browser flickering
« on: February 14, 2012, 09:20:23 pm »
Hey,

So just picked this card today and now i have really annoying problem with it. Randomly when im browsing net and just sitting n dekstop my lower end of screen (taskbar area) starts to flicker heavily and cant get rid of that without reboot. I really dont think the card is faulty as all games works fine but this is really annoying. Also noticed that if i drop my refresh rate to 120hz-> 60hz flickering stops immideatly.

Drivers i have are "official" 7900 series driver 8.921.2.RC11

Monitor i have is Asus VG236H 120hz monitor


Taked small vid to show the issue: http://youtu.be/s7mvJekh6Ho

Hi and welcome.

I expect the problem is to do with the 120hz refresh rate. I am no expert on monitors but my understanding is that 120 is the refresh rate for 3D mode and 60 for the normal mode. That could be why your system works fine when it is dropped down for the normal Windows usage.

Nah its not like that. I had 6970 before wih this same monitor and it worked just fine with 120hz all the time even at desktop use. Done bit research and it seems to be just same bug that has been occasionally in AMD gpu drivers since the release of 5 series cards. It has something to do about  powerplay not working proberly and dont apply clocks/voltages that are meant to be used with 120hz. Dunno what kind of noobs there is working at AMD driver department when they just keep repeating same mistakes with every new series of cards.

Pff well tested the "pre certified" driver released yesterday and still same problem, so likely next whql isnt going to solve this issue either as this supposedly is next official driver. If i dont find some solution soon i think its best to send this back to shop. I know the card is not faulty but drivers for these cards are just patchetic, AMD shoudnt released these cards before they have working drivers for these.

Does anyone have workaround for the 120hz issue

Hi I have just joined to say I have the same problem and it's a card problem changeing from its 2d clock to 3d clock I noticed it on desktop and occasionally in cutscenes on games so I used afterburner to display my clocks and in the cutscenes the clocks dropped.
If you google it a lot of people have this on the 7950/7970 cards the only way round it is to make a profile in CCC and edit it so your 2d memory c lock is the same as your 3d memory clock so instead of 150mhz at idle you have to have it at 1375mhz or whatever you mem setting is in 3d this works but then you problem is your temps rise by about 8c.
I hope gigabyte are going to sort this with a bios or some update because this shouldn't be happening.
Regards
