Is the total rig cost for deploying 4xVega56 optimally higher due to memory requirements for activating HBM2? i.e. 32GB REQUIRED?
Will you also need to run win10? which means deploying an SSD? Or can you run on linux usb stick?
hows about power draw? at what power are those sols produced?
Isn't 16GB of RAM sufficient?
As for power draw, this is taken from Hellae's reddit guide;
VEGA 56 with Stock bios: Target objective: 1800H/s @ 160W per GPU.
VEGA 64 / VEGA 56 with VEGA 64 bios: Target objective: 1920H/s @ ~130W per V56.
4gb is sufficient. the HBCC issue, you can just disable and reenable cards in device manager. No need to toggle HBCC.
I only have 2 rigs of vega and they work with 8gb. (bought a ton of 4gb sticks so most my rigs run 2 sticks)
