So I flashed "290_HYNIX_MOD_V1.7.rom" It flashed correctly, and reported (grenada Xt, etc.) But no changes were seen in Gpuz.
As well as this, after playing csgo fullscreen for about 10 minutes, small artifacts appear, and after a couple minutes, the screen goes black and crashes. I am able to reboot back into windows on the same bios.
I believe the _MOD_.rom has voltage tables from the 390 series card that are lower
than the 290 series.
Try the _Stock_.rom and see if that works for you since it has the same voltages as a stock 290.
Another thing could be that your card has a higher DPM7 VID than stock, you can figure that out using the Stilts evvd decoder from the Hawaii Bios Editing thread.
You'd have to find it in your stock rom and enter the value manually into the DPM7 slot for the correct 6 locations in PowerPlay and Limit Tables.
