Can be, too, add?

v1. 90 GMiner
+ added CryptoNightBBC algorithm for Nvidia GPUs (BBC coin)

2 kerney66

Now got my hands on radeon 7 (power color with samsung mem).
1540/940@850mv + some timings (similar with my vega64) + 13*13 mode and I have 2.77khs.
Is it ok or should I expect higher results with some tuning? I am not considering to increase voltage and gpu clock. Don't want extra heat.
So, is there a way to get boost without increasing gpu clock?

Flash it to bios 64 / 64 liquid, then regkey, overdrive tool 1100/1090/880, for more 20khs you need memory timming
And check it hw info/gpuz your gpu must be under 0.9v for better efficiency

First - quick results for cn-trtl, w/ efficiency-focused settings, using timings mostly borrowing from others here, w/ some minor tweaks:

Vega 64 air, ubuntu 18.04 + amdgpu-pro 18.50, TRM 0.4.3 (L18+18), 852 cclock (p0)/1107 mclock/818mv, power readings at the wall

stock timings:
--CL 20 --RAS 33 --RCDRD 16 --RCDWR 10 --RC 47 --RP 14 --RRDS 4 --RRDL 6 --RFC 260 (--REF 3900)
18.5 kh/s @ 135w (137 h/w)

modded timings 1
--CL 19 --RAS 28 --RCDRD 12 --RCDWR 5 --RC 44 --RP 12 --RRDS 3 --RRDL 3 --RFC 248
19.75 kh/s @ 137w (144 h/w)

modded timings 2
same as above, plus --REF 15600
20.71 kh/s @ 137w (151 h/w)
