7.7Mhs combined on X11 with a 280x+7950 which did only 6.1Mhs combined using
14.4 and default kernels in sph_sgminer.
7950 now 3.6 MHs, 280x now 4.1 Mhs.
Rename your x11mod.cl just in case you want to revert to old version. Ditto for x13mod.cl.
Delete .bin files and restart sgminer ...

I've had amazing results with this kernel with every single card except any of my 7950s. I'm getting 2.7mhs per 7950, but seeing many get over 3 with this kernel. I've brought my farm from 450mh/s to about 525mh/s with the kernel, but that would be about 600mh/s if I could get the 80+ 7950's mining at 3.5+!
The 7970's by far were the most noticeable in terms of an increase on this bin for me. The Sapphire 7970's do 4.1 easily.
As a heads up to anyone that might have the same issue. I went back to look at this again (I didn't heavily troubleshoot while upgrading nearly 50 rigs) and found that the 7950 rigs and a couple 7970 rigs that didn't see a bump in performance actually didn't complete the full ATI update to 14.6. I had to completely remove the prior version, and install from scratch (14.6 RC was released yesterday too) and it fixed the lack of a bump on those machines. I should be at 600mh/s by this evening, when I finish them all.
