Ill test ur CL, RAS and REF timing. Thx pbfarmer.

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
My current        --rp 12 --rc 44 --rfc 250 --rrds 3 --rrdl 3 --rcdrd 12 --rcdwr 5                                                   : 4865 (7.4% inc over stock)
pbfarmer          --rp 12 --rc 44 --rfc 250 --rrds 3 --rrdl 3 --rcdrd 12 --rcdwr 5 --CL 19 --RAS 28 --REF 15600       : 4980 (9.9% inc over stock)

In all seriousness, was w8ing for ur numbers the most and u didnt disappoint  Grin Grin


Most of my settings are just using values which seem to be gathering consensus here - from people such as yourself Smiley  I honestly didn't put much time into tinkering, other than adjusting a couple 'derived' values based on what seemed more appropriate mathematically.  I'd like to look into more, esp CL/FAW/WR...

I mainly wanted to point out the outsized effect of increasing REF, and put some thoughts to what it does, and why it's ok to go from 3.9K to say 15-17K.
