So I just got a new MSI R9 290x Gaming edition. I have a brand new PSU, and no OC on CPU. no OC on card. Stock clocks are core clock 1040 mem clock 1250. When I attempt to mine at anything above -I 13 I get a driver crash. I have tried drivers 13.11 until the newest beta drivers available all with the same outcome. I have also flashed the latest bios from MSI same card just newer bios. My miner settings TC 32765 -w 512 -v 1 -g 1 -I 13 anything higher and it crashes like I said before. But when I lower mem clocks to 1150 and core to 1000 it will mine at -I 18 is it just a bad card?
I couldn't get my first r9 290x, an MSI card (Twin Frozr), to run stable for the life of me above I=13. I exchanged it for a Sapphire brand card and it solved all my problems. Needless to say, I went back and bought three more Sapphires the next day. All work beautifully.
