R7850 Twin Frozr 2GD5/OC - Flickering problem

Question

Hi all!
I have a problem that many seems to have with the 7850 card (Same for different brands) -
When I surf on the net, I get a lot of flickering when scrolling a page. This is the same with all browsers - Firefox, Chrome, IE.
Turning off hardware acceleration in Firefox lessens the problem, but it's still there.
I read on an external page (Not allowed to link) that this is due to low 2D clock speeds.
One user also reported that Gigabyte fixed this with a BIOS update, so I wonder if MSI also have released such a thing?
Btw, tried the workaround with editing the profiles.xml and manually set the clocks higher, which fixed the problem, but this isn't optimal as the clock then works on high load when not needed.
Thanks in advance!

Answer 1

Sorry, maybe a little too fast there
My specs:
OS: Windows 7 Professional (x64) Build 7601, Service Pack 1
Motherboard: Asus P8Z77-V Pro Intel Z7 (BIOS version 0906)
RAM: Corsair Vengeance Low Profile DDR3 PC12800/1600MHz CL9 2x4GB (Profile set to: XMP 800.0 MHz)
CPU: Intel Core i5-3570K, 3400 MHz (Using "Standard" mode)
PSU: Corsair Power Supply 750W HX ATX
GPU:MSI Radeon R7850 Twin Frozr 2GD5/OC 2GB
HDD #1: WDC WD2500KS-00MJB0 250 GB (OS is installed here)
HDD #2: WDC WD5000AAKS-75TMA0 500 GB
DVD-ROM: ATAPI DVD D DH16D2S
To clarify the error report:
Everything works perfect except for web surfing where I get strange millisecond long flickers/flashes, when scrolling a page.
If I check the AMD OverDrive, then I can see that the core speed is 150MHz, and the RAM speed is 300MHz as minimum and then goes higher when I scroll a page. And as I wrote, if i manually change those values in "C:\Users\<username>\AppData\Local\ATI\ACE\profiles .xml" to work for example in 700Mhz as minimum, then the problem is gone, but with the cost that the clocks works on too high values for what's actually needed when the system is idle.
