Afterwards it crashed during gameplay, so I wonder:
Is there a reason that after flashing Tahiti.rom my voltage would remain stock but my clocks go to 1100/1500 as planned? What can I do to get 1.256 voltage as well, as it is surely necessary for the OC caused by the flash. Would re-installing the drivers somehow help this? Am curious.
EDIT: Actually my voltage is even lower than I remembered - it stays at 0.850V, even after flashing the BIOS as described above. Any ideas?
Got a 2.1 rev card a few days ago, was doing some research on it before and found the bios flash from the ghz edition from here, so just posting my results. Got my card on Wednesday, I already prepared a boot stick with the tahiti rom and atiflash, didn't want to bother with it without the flash and flashed it right away. Used the command "atiflash -p 0 tahiti.rom -fa -fm -fp -fs" and everything was fine.
When testing out Crysis 2 and Far Cry 3 the games crashed with the amd display driver stopped working message. Tried 13. 1, 13.3 Beta 3. 12.11 using the ati removal tool to remove the previous drivers without any success. Was having issues with the OpenCL when trying GPU-Z, and it didn't go away with any of the drivers which I didn't have with my 6950. Tried overclocking it but it stayed stable in windows but the games would crash and amd driver stopped working message would pop up. So i decided to downclock the card to stock levels and all was stable and well, then increase by 10mhz at a time, 1080 mhz was all it was stable at, any higher the display driver would stop working, so I ended up with a poor overclocking card.
Returned it on friday and got another one hoping for some luck and no issues, OpenCL working perfectly with 13.3 Beta3 and stable in games at 1100/1500. Used same method to flash. stable at 1120/ 1500, satisfied with the card now that its basically a ghz edition and can overclock decently. Might try going for 1200 when i get the rest of my new rig. So if your card crashes in games, i suspect your chips limit is lower then 1100 so i suggest you return it and get another one. Every chip overclocks differently, you can only hope you get the good one.
