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.
To save you the searching here's a link to his post on reddit

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

Change your intensity setting to xintensity 128. You'll see a very significant hash rate jump. Also, are you using sgminer 5?

HoY --

I am running sgminer 4.2.2-, the build identifier is in the posted image. It is a set of pre-compiled Linux binaries, released by the dev team just before Christmas, that reportedly had Wolf code. I keep downloading and compiling sgminer 5.0.1-, but began having stability issues a few weeks ago.

Thanks for the tip, I'll try it. --scryptr

OK! I tried it. See the image below:

You can see in the image that I changed the Intensity of "13" to an xIntensity of "128". That is all that I did.

However, I still have stability problems. I am running AMD drivers 14.6 beta for Linux x64. The stability problems began happening as the sgminer code incremented from version 5.0 to 5.0.1 (or 5.1, in some versions?). --scryptr

EDIT: Apologies for straying slightly off-topic. This began as a comparison of Cuda vs AMD. I am suprized by the results that it led to. Apparently, I've doubled my x11 hashing capacity in a couple of hours without spending the money for 6x GTX 970. I will, eventually! Wink

--scryptr

those are nice hashes - but i am getting slightly more than that with the 5.1.0-dev sgminer ... you can download the dev version from nicehash/westhash also - or compile it yourself under x64 linux ... though i think the latest is faster again - with wolfs kernels ...

what is your commandline settings for sgminer?
