XFX Radeon RX 570 8GB, good for mining?

[Lunga Chung]

Can you please help me? I have a couple of RX 570 8gb RS XXX (exact model RX-570P8DFD6) Hynix memory, tried 10 bioses, whenever I undervolt the card, it is crashing on SMOS, this is the only stable setting but it is too much power.
Heck I event asked XFX official support to sent me their bioses, tried them stock, modded with polaris bios editor (the straps with one click) still same results

Max and stable OC settings:

Core clock 1140
Mem clock 1900
voltage 1087 (default if I lower it the rig crashes)
PowerStage 3
Aggressive undervolt off
29 mhs for 150watts

As I said above mining on SMOS without risers, directly on a new motherboard so the hardware is not faulty.

I had exact same cards, most of them could do 30,5~31 but with following settings in OverdriveNTool under Win

Core clock 1165-1175
Mem clock 1900-1920
voltage 900 -925

Orginal BIOS with PBE, give us PSU model and W also the motherboard model

I am using SMOS for that card haven't tried OverdriveNTool in Win. Also tried the Original BIOS with PBE one click, still the same issue.

Can you please tell me the memory type in your cards?
I have tried the same model of card with Micron memory and it is rock solid 31mhs on 850mv with 1160 Core and 2000 Memory, the problem is with Hynix

Most of them where Hynix some Epida....the strange thug is your voltage

Yes I can settle with less hashrate but 150w for 28mhs is way too much for rx 570

Hello

I'm thinking of riding a rig with these gpus, they have a very good price.

Seeing that the memories do not have refrigeration, the models I have tested of sapphire, gigabyte and msi (570) all have refrigeration.

My question is if these memories get very hot, has anyone used them to mining these XFX rx 570 8GB?

Cheers!!
