Intensity 20 on these cards gives me way too many rejects, I found 18 is the best setting (< 1% reject).

Stop using intensity... switch to shader multiple threads - xintensity. Intensity is completely antiquated now.

Intensity - raw(?) - xintensity
13   8192     2.90909090909091
14   16384   5.81818181818182
15   32768   11.6363636363636
16   65536   23.2727272727273
17   131072   46.5454545454545
18   262144   93.0909090909091
19   524288   186.181818181818
20   1048576   372.363636363636
21   2097152   744.727272727273
22   4194304   1489.45454545455

So you are suggesting an xintensity which corresponds to between 21 and 22 whereas he's saying a value closer to 18 (93) reduces rejects.

In my own setup I tested xintensity keeping other values constant. Values higher than ~372 (such as 1100 and 702) were causing some throttling issues i'm assuming due to gaps in utilization (temp pretty cool throughout). Values lower than ~372 (such as 176 and 93) reduced the hash rate with no improved thermal performance. I don't have any reject % numbers though and I will test that again later.
