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).

Can you explain this, i'm interested in getting this hasrates and also any optimizations for my wonderfull 56s Pulse nano watercooled???

What PPT/timing to use for "all-cryptos-round config" with  Vega56-113-376XL-UO2-180315.rom
More specifcly what timings for ETH?

I'm ready to share all i have (PPT, Monitoring...) and i have a lot, so if you guys are interested... 975mem on our tinies nano pcb+hynix mem is that a joke?
Just need to set to maximum "sclk 5" right?!


My rocm-smi PPT, Ubuntu 18.04, AMDGPU-Pro 19.30:

I hit 42.6 with Hynix and 44.9 with samsung stock timing!
