Graphics Card

XFXHD6670 - just new RMA'd - thought hardware issue - no same issue.

AMD Catalyst Driver Version, and Driver History

running 13.9 now - have gone back to 9 - all have same issue.

Operating System

windows 7 64bit - ( I think this is a specific driver/OS issue)

Issue Details
- This is an issue I think specific to Windows 7 64bit and the HD6670.

This started when I installed the HD6670 into this this system and was running my win7 64bit OS. I have a dual boot system and also have windows XP on - I like to play old games. 

Primary issue is video playback - about 30sec to 2mins into playback it will either freeze, stutter, go out of sync. Usually it will not fix itself I need to pause the video and it will fix and go again in 2mins? 5mins? 10mins maybe. Size of screen no difference, format no difference. Player no difference. 

If I play the video on windows XP - same machine  - No issue.

Total war games and several others I will have driver failed and failed to recover crashes - ONLY in later stages of the game. 

I have an NVIDIA 8800GT that will work in win 7 64bit and playback video fine, this was the previous card - SAME hardware.

I have done a safe boot, and selective boot, issue is still there. If I boot into winXP I can pick VLC player and any video plays.. no issue.

I think this is specific to the HD6670 and win7 64bit.

- If I just swap this card out and use the 8800GT - problem resolved.

I solved this by buying an NVIDIA card.

I was never able to get the 6670 to work on my system right.

A gt630 plugged right in.. and all problems were solved.
