Why such on experiments with noname PSU? Why not take branded one?

i think so too. it is  about the same that employ DC-DC inverter.
i use blade server's PSU with convert unit,like this.

I have three vega 56 with 64 bios

seems they can do 1105 mem and 38 eth and 150 lbr or 40 eth solo

the core voltage says .91-.96 in GPUZ , you were getting lower voltages ? I have the same drivers as you.

Also on two cards only half the red lights are lit up but on the other one all the lights are lit up ? wtf ?

If it PSU, why different LED indication on cards?

One riser(molex) per one cable.

Depends on how sensible you are to sounds, that being fan noise, you would certainly be able to hear it.

I have a question of the ppl having stable hashrate over or close to 1900+ H/s - what kind of settings are you using with VEGA 64 ?

I have trouble getting it stable at 2016/1600, so I am using 1900/1600, but on the  cards that are fixed with the first Oldcomer's registry mod I get around 1800 ea. The other one is slightly better, but I need to fix the registry on it too, as its probably consuming more power so - can you suggest any really good settings (and maybe link to reg file) ?

Sapphire RX Vega 56 sold by NewEgg.com on eBay w/free shipping:  $419

Maybe I will grab it.

no wonder they are so cheap.
