Just posted a optimized x13mod bin file for 7950 (and possibly 280x,290x and other 6xxx,7xxx)
compiled with sgminer 4.1.0 cat 14.6RC2 for those not wanting to upgrade to 14.6 RC2 at

Please post in my thread if this works for you

Baah... trying your bin for X13 and only getting around 2280KH or so at a total of 9.12MH for my 4x 7950's. Same rig gets over 14MH on X11 with another modified bin.

Not to butt in, but isn't that more or less normal? I was expecting to see about 30% less hashrate on x13 vs. x11.

Maybe the numbers people were quoting on the linked thread skewed the perspective a bit... some people were getting 2600-2800 with 7950s and that bin file.

I'm seeing just under 2.7 Mh/s per 7950, my config & setup is posted over there. You probably have a little headroom somewhere.
