Just a word of caution, I woke up to 1 dead R9-290 this morning after mining scrypt-jane, the card was only 1 week old.
It may just be coincidence but If you look back through this thread a few people using the same card have noticed problems afterwards.
I've managed to take mine back and have traded them both for 2 r9 290x's now.
If they show up "DEAD" it doesnt actually mean that your card is broken, you know that right?
Means it has been unable to function, so CGMiner stops trying and calls it DEAD.
Mostly it's because of insufficient power, but there are some other reasons for it...
Try lowering the intensity a little bit, or if u have underclocked your GPU add like 0.010 VDDC to it.
Anyways if ur card shows up DEAD, just restart your PC and start mining again
I had an XFX r9 290 that I had in for about 3 days in December and I tried mining TIX (another scrypt-jane). It failed and reset my system everytime the driver loaded from then out. How to RMA it. Just curious what brand you had this happen with?
It may just be a coincidence, as it wasn't running more than 2 days before it failed. It's replacement has been running for about 2 weeks on normal scrypt without a hickup and 24 hours on scrypt-jane just fine.
