Yes, just paste that bold hynix strap from Eliovp's post in yours 1625, 1750 and 2000.

Mining Music now, but it's the same for ETH.

Yes, bold one for hynix. I'm using it with my RX470 Nitros non plus.

Or you can still mine Ethash at 24-26Mh/s with hd7950, just not ETH or ETC.
Try Musicoin(MUSIC), Expanse(EXP) or Ubiq(UBQ). And you can dual mine DCR if you really want to do that.

I'm using 17.4.3 (with atikmdag-patcher-1.4.5 patch for BIOS signature check).
