Wow I just got these modified kernels for sph_sgminer with 14.6 RC2 I am getting
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 ...
http://puu.sh/9Bkmt/c7f933e297.7zI'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.
Upgrade done, pushing about 590 mh/s on waffle now with the same gear. Not fun upgrading Catalyst on 49 rigs, but well worth the results!
From what I've seen on all of my rigs, the most recent x11mod and 14.6 beta (RC2), I max out on my 7950's right around 3.6, and the 280x's around 4.2, so you're in the zone. I don't have any powercolors, so I'm not sure if it differs much. I use different settings then you have, mostly xintensity and my thread-concurrency was bumped down from the typical 24000 to 8192, but the results are the same.
Hey, do either of you know how to get the 14.6 RC drivers to run six 7950 gpus on win 8.1? I've been waiting for something to pop up in a thread dealing with 6+ gpus & windows on another board but haven't seen anything yet.
Right now I'm running the 14.4 drivers with modded .inf files and lasybears x11mod here on wafflepool. Seeing about 2.98 mh per 7950 card with 8 amp total draw, which is pretty nice. I Just "upgraded" from win8 to 8.1 in hopes of moving to the 14.6 drivers once I can figure out how to run six cards with them, but just loaded the modded 14.4 drivers in the meantime. I know that I'll have to change the x11 kernel to work with the 14.6 drivers, and I saw some people talking about loading some portions of the 14.6 drivers into the older driver folders to get them to work easily, but not too sure about that.
Please post configs that are working for you ... card type, MHs, power draw if known
also what version of sgminer you are using.
Warning do not update to 14.9 WHQL, u will murder your hashrates all algosLink to latest 14.7 catalyst RC3:

6+cards seem to be working ok with 14.7RC3 now out of the box Here is previous 14.6RC2 since new release candidate is out:

sgminer 4.1.0 kernels folder.
Optimized x13mod bin file for 7950 Tahiti (and possibly 280x,290x and other 6xxx,7xxx) compiled with sgminer 4.1.0 catalyst 14.6RC2 for use with catalyst 14.4

x13modTahitiglg2tc8192w256l4.binIf you want to try another TC or WS on X13 let me know and I'll compile and try it and post bin.
To try with non Tahiti card try editing file name to Hawaii or whatever ...
I'm also interested in collecting X13 vs scrypt hashrate info.
Remember this is a testing thread, your mileage may vary
If you are having trouble, please post detailed info what u are using, what problem is
There are no mind readers here LOL.
Read the thread, your question/problem may have already been addressed.
