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.
