Is there any solution for the non ref 56 cards that have a default of 800 mem and can’t go past 900-950?

I got four of these crap cards any thoughts ? Three are red devil 56 power colors and one is a sapphire pulse
If you're lucky, you might find a Vega 64 vbios for that same card (if they made em both 56 & 64), which is unique.. not much out there, Pulse, only 56 afaik.

That however doesn't mean they're crappy, i've got a Sapphire Pulse with Hynix memory and it's running smooth at 47~Mh (memory at 975).
Got a Samsung Vega56 too and hits 48+Mh..

The thing is, they only have 6 SOC states, so it gets auto forced into a lower memory state (800MH), you can see this in the tool..
Vega 64 has 8 SOC states, therefor it goes to the highest memory state (1000Mh).


is there way to apply straps like the claymore miner ?
for polaris

GUI version has an export/import feature, you can use that.. "kind" of the same.


Hello,

I have strange problem with one rig with 3 vega 64 liqued cooling.
I try many memory tweaks with latest memtweak cli and got 51,5 Mh/s on each vega, but pools (ethermine, 2miners, miningpoolhub) show disconected status. But if I lucky and pool accept connections -> low end pool hashrate
HBM2 1100 and CORE 1050 on all three cards (Win10x64 1809). Tried claymore and phoenix. Coins - etc, eth, exp
When i reset timings - all card hashing without problems on pool.

Thank you in advance for any advice.

I'm not able to reproduce this, just to be sure i let my Vega 64 run at 53Mh for half an hour, pool hashrate was spot on.

What are your timings?

Cheers!
