My 290X is making a nasty "seek" type of sound. It certainly doesn't sound normal. It is also performing poorly and doing a half-assed crash to a black screen where audio is still going but kb/m are unresponsive. It forces a power cycle. It can't even muster a BSOD. GPU-Z sensor logs look just fine. I've tried all of the drivers and am on the most recent beta's.
If your getting the black screen crash without overclocking at all, more then likely you might have one of the faulty cards
I have already sent a R9-290 back that was doing randon black screen crash + hard lock, and could not use it for anything
