Stock Timing : 4530 h/s
Todxx Timing : 4800 h/s

Is that working stable for anybody?
that rcdwr is very low. GPU crashes in a few minutes for me.

Yeah it crashs after 1.5 hours. Also curiously it crashed on the best silicon i had Huh

Not the weaker cards.

I'm also stable with the same timings and --rfc 250 which gave me an additional boost. Modified timings would be

Code:

--rp 10 --rc 44 --rfc 250 --rrd 3 --rcdrd 12 --rcdwr 5

EDIT2: here we go, increased --rp from 10 to 12 and that weaksauce-GPU is doing 21+ kh/s like his little buddies. Ka-pow!

BTW for current version '--rrd 3' should be replaced with '--rrds 3 --rrdl 3' otherwise it won't be set

Results:
Cards : Vega 64 (aircooled, reference, samsung)
Miner : SRBMiner 1.8.3
Algo : Cryptonight litev7
Clocks : 1408/1107/875 (ODT)
Actual : 1354/1107/850 (HWinfo)

Stock : 4530
Todxx --rp 10 --rc 44 --rfc 300 --rrd 3 --rcdrd 12 --rcdwr 5 : 4800 crashes in 10-15
Based on above --rp 12 --rc 44 --rfc 250 --rrds 3 --rrdl 3 --rcdrd 12 --rcdwr 5 : 4870 stable
