What is average hashrate on Vega 64?

Make sure you have modded timings in place, CN timings should be good. I haven’t done much testing myself for c31, todxx has been driving it. That said, getting 1.15-1.25 on V64s should be doable, but I don’t know what the efficiency curve looks like.

will you release a version for navi? 

THX FOR ADDING MTP and other algos keep up the  good work  !!!  is 3.5Mh achievable on vega 56 (64bios) CN timings drivers : 18.5.1 ,  ( I dont care about power )   ??
As nicehash user im trying to beat the profitability of vega 56  2300h on cnr ...
(2 weeks back when Btc was spiking mtp was extremly profitable even  3.0mh on mtp was more than 2300h on cnr )
 
with my Cn settings i get around 2.8-3.1

On WC 64  i get 3.6-3.9 which even rivals  1080ti

Blockchain drivers are a little bit outdated my friend! Get at least 18.6.1.

You may also need to adjust your clocks/voltages compared to CN.
Some parts of c31 are very core/compute intensive and may require either slightly lower core clock or slightly more core voltage to keep the GPU stable as it warms up.

Good luck finding Fury with 8GB. AFAIK 4GB is what You can find.

There is no 4gb solver so Fury will never mine Grin31. I've started selling my Furies a while ago, only 1 left now, hope to get rid of it soon))
