  1. What are you using to test?
    Are you running a game at that time?

    May wish to try this to log the changes in clock speeds.

  2. Unless XFX mess up the speed should have been programed into the cards bios. I would have to recommend getting a hold of XFX to see if they have a solution(I dont generally tell people to just flash a card.).

  4. Hey, I was wondering if you ever solved this issue. I was looking at my stuff yesterday and noticed that my 6670 is only running at 667 Mhz Memory Clock, and according to http://xfxforce.com/en-us/Products/Graphics-Cards/AMD/AMD-Radeon-HD-6000-Series/AMD-Radeon-HD-6670/HD-667X-ZHF3.aspx it should be 1.6 Ghz. I have contacted Xfx but haven't gotten a response yet.

    My Specs:
    Amd FX 4100 Quad Core 3.6 GHz
    XFX HD 6670
    8 Gigs DDR3
    Generic 450 Watt PSU
    Gigabyte 880GM-D2H

    I have a very similar build, same problem I tried overclocking to 800 MHz but the screen got ugly red dots and steaks of white, so reduced it.
