utahjohn - so continuing the conversation from the Wafflepool thread...
I backed up all my configs and updated to the PiMP 1.5.5-amd-14.4 distro image which has Catalyst 14.4.
Copied over your optimized cl files and the bin files (your X13 bin and someone else's optimized bin for X11).
Results are almost exactly the same as I had under the 13.12 drivers on 14.4:
Any higher on "some" of the GPU's core/mem speeds get me HW errors or SICK GPUs.
Playing with other values such as variations on intensity, shaders, GPU threads, etc, get me lower values than these.
Any ideas?

I've been seeing my highest hashrates using I=18. If I go to 19 or higher, or 17 or lower, it will fall off.
Try I=18 and then see if you can goose the memclocks up 10 at a time and see what happens.
(If I go above 1500 memclock, or 1100 engine clock, my gpus will start checking out.)
What are you using for gpu threads? 4 seems to work ok for me, I will lose hash if I go to 1. I forget what happens if I go to 2 or 3.
I have sapphire hd7950 though, don't know much about the MSI cards other than they might drink a little more power.
Edit: Also wanted to add that I'm using the lasybear x11/x13 miner, although I don't know if the modded x13 kernel loaded into a different sgminer basically would give the same performance. Maybe trying that miner would help. It is based off of the "2% fee" miner but does not send hash out to anyone.
