Hi all, just got 2x Aorus 580 8gb thinking they will perform better than thier 4gb (Hynix Ajr) counterparts. Ended up discovering that this Hynix h5gc8h24mjr is SO different than the the Hynix AJR!
The 4gb RX 580s aorus hynix Ajr are speed devils, i was wondering why people curse hynix if i can run them ~ 1200mhz/2125-2200 getting 925-1008 H/s! (and can still go higher stable!!! with GG 1.3 pre6b or GGS but rather keep them at 1200-1225mhz core)
So far i tried the following with my 8gb (h5gc8h24mjr) 1536(RI)x2(Threads)x8(Work) and many many variations with 1250 mhz/2250. nothing so far gave me anything above 900 h/s!
With Eth though, they perform really well equivalent to the 4gb (which can steady 32.5 mh/s!)

My questions now, i tried both those straps they are quite similar, the cards max reaches 2100mhz and then gives artifacts (if main gpu) or just blue screens.
So shall i just pass the 2250 limit and overclock memory as far as i can? with a higher core clock as others do? (i didn't like the idea to have a 1350/2350mhz undervolted mining, feels so stressy for mining)?
What Raw intensities worked for you guys with the same memory? the 896/8/2 GG is insanely a sweet spot for the 580/570?

Try R0land's fixed timing:

zeroed: tFAW, t32AW
fixed some others.

reduced write recovery
reduced actrd, actwr and RP/WR+RP
