This is a good 1750 MHz strap for Sapphire Nitro+ RX580 8GB cards with Hynix memory from BuriedOne on Youtube.

I copied it over the 2:1750, 2:2000 and 2:2250 timings on a Sapphire Nitro+ RX 580 8GB Special Edition (blue faceplate) and get ~29.25 MH/s ETH + 935 MH/s DCR with a core clock 1120 MHz, memory clock 2200 MHz, -96 mV undervolt and power limit -15% in Afterburner. Runs stable with no memory errors.
