What about the newer RX580 with dual memory? I have 2 of these with Samsung and Hynix(secondary). Currently mining at around 860-870 (after a great number of tests with different mem timings, OC/DC and miners) with 1200/2200.

There's no such thing as "newer RX580 with dual memory".

Each card only comes with memory chips of a single particular brand. For the most 580/8 these days it's either Hynix or Samsung (heard of cards with Micron, but never saw them myself). The manufacturers are just too lazy to bother with writing separate BIOSes for each memory type, so they make one BIOS with straps for 2 or more memory types in it. If the card has Hynix chips installed, it'll use the straps from the Hynix table, if it has Samsung chips then it'll use the straps from the Samsung table etc. So when you edit your BIOS, you just edit the straps corresponding to the memory type installed on your particular card. Judging by your clocks and hashrates, you've got Hynix chips on your card.

Cheers, didn't know about the memory and the dual BIOS straps laziness. Anyway, the memory is Samsung and I was modifying only the first set of straps. The cards are Sapphire Pulse if this matters. I was thinking if the memory is just one brand, shall I make both straps exactly the same for all frequencies...
