MSI Armor RX470 8GB Doesn't Act Right.

[philejmath]

I got what I thought was a good deal on 10 MSI RX 470 8GB cards, expecting ~22Mh/s ETH

Well it's more like ~18Mh/s. No biggy? probably the AMD DAG Epoch issue I guess...

So I tried some Monero mining and I'm getingt ~500H/s per card

Seems very low compared to what I've been seeing for these cards.

I want to put them all into the 13 GPU ASRock board but now I'm wondering if I should just return them...

It's normal for AMD cards right out of the box. You have to Bios mod them and find the best settings for the cards. Using the PolarisBiosEditor v1.6 'one-click timing patch' will automatically detect the memory type and apply the bundled performance straps. Then just save the Bios and flash it to the cards. With a Bios mod and 1200 MHz core clock and 1975 MHz overclock for the memory should get you to 28+ MH/s on ETH and 740 MH/s on XMR.

Thank you. I've been searching for the Linux version of this advice. That looks like it will work.

Yes, it should work with Linux. PBE will work under Linux using mono and there is also a Linux version of Atflash. Backup your original Bios before flashing the modded one.

I have one, its currently running at 23 with the bios mod and the dag issue driver, and i've not overclocked it alot, just at 1750, it was running for 26 at some times but i don't know what i changed and it got back to 23-24, i used anorak's bios, you can do it yourself too.
