Hi,
I'm having a strange problem with 2 of my GIGABYTE AMD Radeon R9 290X OC 4GB GDDR5 cards. I used to run them on two separate rigs, each with 2 other identical cards, after two days of mining CGminer 3.7.2 would close for no reason, windows 7 still functioning. After a restart the boot screen had a vertical pixelated line going down the screen, after Windows 7 starting logo the screen goes black, restarting again doesn't solve the issue.
My CGminer 3.7.2 setup:
1 Started with a .bat file with
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
Thread concurrency 32765, GPU Engine 908, GPU Memory 1500, etc.
2 Created cgminer.conf
3 Started CGminer through CGWatcher
I have 2 rigs with 6 identical cards total mining full time for the past 3 weeks without any issues, same CGminer config, Windows 7 Home Premium, ASRock 990fx extreme 9.
I've tried running one problem card on a test rig, fresh windows install, 13.12 Catalyst drivers. After the first restart same problem happens, pixelated boot screen and black screen after start logo, card is not overclocked, haven't touched the voltage.
Has anyone else encountered this? Only happened with these 2 cards out of 8, hopefully I don't have to RMA them.
Any advice is greatly appreciated!
Thanks!
