Hi guys,

I'm sure this has been reported/discussed countless times before however I'm wondering if AMD will be addressing the issue in a driver update? I've experienced the flickering issue since purchasing the card in January and I feel a card of this value ($550) shouldn't be doing this but reading online it seems the 79xx series in general is affected by this issue.

The problem is my screen intermittently flickers in 2D. It's mostly when I'm browsing or watching videos. Browser & flash hardware acceleration are both disabled and the card has never been OC'ed. I use the DVI output but have the same flickering with HDMI and displayport. I've tried by old 4850 as well as on board graphics which eliminates the problem. See video below which I took last week:

Sapphire support advised increasing power control setting to +10% in CCC which didn't have any affect. The core core defaults at 300 MHz and memory defaults at 150 MHz even when watching videos in 2D. I've tried pretty much all the 13.x driver tree over the year (cleaned out the old driver each time) and I'm currently rolling with 13.8 beta 1 but the issue is still present. Here are my system specs

OS - Windows 7 x64 SP1
CPU - Intel Core i5-3570K, 4300 MHz (43 x 100)
Motherboard - Asus P8Z77-V Deluxe
RAM - 16 GB
PSU - XFX 850w XXX Edition

GFX Card - SAPPHIRE HD 7970 GHz Edition 3GB GDDR5 VAPOR-X (11197-12-40G)
Chip Type - AMD Radeon Graphics Processor (0x6798)
BIOS String - 113-210XT2H-X0B
GPU Code Name - Tahiti XT
DAC Type - Internal DAC(400MHz)
Driver Version - 13.200.0.0
DirectX    DirectX - 11.0

Thanks
