RX Vega 56 & 64

[starcat]

NONE of the Vega 56 BIOS from Tech Power Up with the same ID strings will operate on the Sapphire Vega 64 reference cards I have . They will install but the miner application will stall and fail to run. This is the case with LOL or NB, same result. Revert to the original 64 BIOS and they come up and run. I have about 6 different BIOS files, and one that was given by a real supposed PRO. None of them will run at all, so this is yet another case of people claiming results which do not apply across the board as is the case with Polaris cards as well.
If anyone has a 56 BIOS that will actually install and run these cards at the 51-54 MH, I would be very grateful to try it, but something is off with these cards for whatever reason. They were also factory refurbished, and the stock BIOS downloaded off them was odd in that it seems to be a Powercolor BIOS on sapphire cards. Very strange.

Never trust the bullshit watt that can be displayed
RX 580 reported @70W ?
Vega @100W ?

Nope !!! From experience and Wattmeter to the wall
RX 580 ~100-110W
Vega ~140-145W

True, the results I got from my rx580 and a old Vega 56 card of mine was even higher than yours, I used wattmeter to measure the power consumption for each cards

RX580 ~ 120w from wall
Vega 56 ~ 150W from wall.

I believe that silicon lottery also have it's part to play.
