scryptr you are getting about 40-45% of expected performance from your 280x's. with even mild over clocking (1100/1500) they do 6.5mh/s per card using Wolf's recently released bin files.

Yeah, it's been a while since then, surprised more people don't know.
X11 HASH: CUDA vs AMD--
To be fair, I re-downloaded and substituted the Wolf Tahiti-x11 binary. This time I took the additional step of write-protecting the *.bin (binary) file before booting sgminer. I got the following results upon firing up the same sgminer as in my earlier post:
I am running my GPUs at 1030/1500, stock clocks for my 280x cards. I will try faster clocks later, but I am having a real problem with stability. GPU0 crashes within 10 minutes if I don't disable it. I disabled it at about 9min 30sec, after I clipped the image above. It had started to misbehave again.
Any card management tips would be appreciated. --scryptr
