For those of you who have tweaked your settings since the 1024 diff increase.. What have you changed in your settings? I haven't changed any thing on my system yet.. Its still chugging along OK, just curious if there's something I should take another look at.

My final setting as of a few hours ago are similar to my original setting. I dropped intensity from 19 to 18, and increased TC from 24000 to 24192. I seem to have dropped about 15KH, but gained about 60WU. I've also gone from approximately 5-7% reject rate to 0.38%. Granted this has only been running a few hours on one 7950, but I'm going to see where it sits after 24.

(5s):638.4K (avg):635.4Kh/s | A:270336 R:1024 HW:0 WU:643.8/m

Finally a constructive post, thank you. My 7950's rejects rate decreased 3% after I changed I from 20 to 19, and the hash is down by just 10kh. I will try increase TC from 24000 to 24192 and down I by 1 as you did. see if that improves re furthermore.

Glad I could help. I remember reading that the TC was normally best when divisible by the number of stream processors, but everybody seemed to get the best performance at 14000 so that's where I started. I then tried 12,13,14, and 15, but 13.5 * 1792 seemed to work out best so far. Here's my full arg string. Let me know if you see anything I should tweak further after your testing!

-I 18 -g 1 -w 256 --lookup-gap 2 --thread-concurrency 24192 --gpu-powertune 20 --gpu-engine 1100 --gpu-memclock 1450 --temp-target 80 --auto-fan

Thanks for your explanation on how to get proper TC
Really helps alot on my 7950
