There are timings, in full view, on this very forum for MJR that give 1200h/s on cn heavy at 1244/2125 570 nitro+ 8g.
Just keep looking.

This forum is very big. And I can looking for years in search of right info. Maybe you share it to save our time?
Its no secret, 999000000000000022339D00CEDD6B4470551414B80D960B0040C400750314204A8900A00200000
018123745B92B3A16 Doktor put it in SRBMiner thread, and its really good compared to the one click strap.
Zawawa, some issues in latest version:
*Rx 560 2gb doesn't want to get the timing optimizations, neither do the R9 390
*GPU current clocks aren't shown in overclocking, instead are the last copied ones (copied from similar device etc.)
*Work size (4) in cryptonight should be enabled, if possible (for some odd GPUs i believe).. for some reason R9 390 on V7 gives similar results to claymore with two threads and a 740-820 intensity and most importantly 4 work size rather than 8.
In Old GG some GPUs of 2gb size were able to fit 448 intensityX2 threads, those gave noticeable higher gains in speed, not sure what rules, but, read somewhere that elpiads are different than samsung and hynix etc. in amount of memory available.
And you with doctor's timings and 1244/2125 clocks recieve 1200 h/s in GGS? What intensity? Can you give screen?
