I'm curious myself how you're getting 13.6 MH/s with your 280X, I'm pretty much capping out at 12.86MH/s on my 280X on NIST5
https://dl.dropboxusercontent.com/u/93497958/Capture.JPGAm actually getting 13.8MH/s each now. Latest SGMiner v5 with 14.6 Beta (rev.1) drivers. 1X 280X Sapphire Dual-X and 2X Gigabyte 280X OC. I also have a Sapphire Vapor-X running in another machine at similar speeds.
