Hello, I got a good offer on ES HD7970 and the card performs well, the only con that at idle mode, the card will produce little whine or squeal according to what happen on the screen, noticeable while scrolling the pages and moving the cursor. As I knew it is bios issue with the ES 7970 with the idle clocks regarding the ram clock or timings. I tried the change the bios to the GHZ Reference bios "C3860100.102", flashing goes fine but as soon as the windows loads, it will bsod with 7E code. I have to remove the drive or reflash the card to load the windows fine. The ES card comes with bios "C3862000.004"
I noticed all the retail 7970 cards come with name "Tahiti B0 XT2 C38601" while the ES comes with name "Tahiti B0 XT2 C38620" If someone have a reference bios has the same "C38620" with date newer than 6/7/2012, I would be glad to try it.
I tried the Club3D 7970 RoyalAce bios, it flashed fine and the whine or squeal at idle disappeared but the card wasn't stable at 3D. I know it is ES card and there is no support for that but maybe someone has a newer bios for it?
Thanks
