I still can't reach the power draw of 130w for vega 56 like hellae

The reg mod for the flashed vega 56 is causing gpu core to run at 1410mhz and even if I reduce it to 1210mhz it still draws 977w at load for 4 cards. Idle is about 130+w.
I'm using the common setup of g4400, 4 Gb ram.

Another thing is, i can't change the hbcc ram level at all. The slider is Greyed out and stays at 97xx mb.

You will need 8gb of ram to activate hbcc using Wattman. I've heard it can be done by disabling each card in device manager then activating again but I haven't tried thisywelf as I had bought an extra 4gb before that fix was found. Still not attempted the reg mod for the power consumption yet. Currently running 4x Vega 64s at 900W 1950h/s per card

I'm also 4x vega 64's, 1990 or so (though i am on lc if that matters). You can definitely get that wattage down if you care. I had zero problems with the reg mod (from hella). Definitely worth a shot if you have an hour or two to spare.
I've yet to test the new stak, but want to get that cpu up and running as well soon. Hopefully push out another hundred h/s and check if it's worth it.
