Title: One 280X of a 5 Gpu rig shows a lot HWs. Post by: MajidBC on June 06, 2014, 08:39:42 AM I have a rig with 5x Sapphire Dual-X R9 280X. They are all the same. When I used to mine scrypt coins one of them used to get hotter than the others, and it was not related to any other factor, it was the card. Now I'm mining X11 coins, that one shows a lot HWs. I've attached an image of sgminer. Can I RMA that?

OS: Ubuntu 14.04 MB: MSI Z77A-GD65 PSU: 2x Corsair 850W Ram: Kingston 4Gb CPU: Intel Celeron 1620 Miner: 40% optimized sph-sgminer Title: Re: One 280X of a 5 Gpu rig shows a lot HWs.

Post by: romulus_ut3 on June 06, 2014, 05:50:34 PM Try the card on a different machine, or connecting it to a different slot, take out one of the cards and swap it with the card you suspect to be faulty, and see how it behaves. It could be faulty, yes.

But generally speaking, with 280x, they should work fine with stock settings (they won't be optimized though) without h/w errors. So if you do get h/w errors at stock, it's most likely a faulty card so just RMA it.
