I do have custom timings (one-click in PBE which is a 1:1500-2000), which I think is the only reason I'm getting the hash I am. I'm just surprised to see that huge of difference in ram quality between manufacturers. I had another incorrect share pop up so I've since lowered again to 1910.
My Hynix cards shine for sure, two of them at 1200/2190mhz (~930H/s) and are picking up the slack of my rig. 690w @ the wall btw. I like it.
Well you've not experienced the insane performance drop on 1060s. gtx 1060 with Hynix can't even do 21 Mh/s while those with Microns and Samsungs can do 24-25 Mh/s (with same kind of overclock)
Here's one Elpida of mine 31.2 + 300 while mining ETH+PASL. That's a RX580 Nitro+ and a Gigabyte Gtx 1060 with Hynix memory.
