Elpida on the other hand, most of the times max out at 1450.
Maybe also the impressive cooler on the Tri X and cooling pads on the memory helps? guess so.
BTW did anyone played with Aux voltage? worth it to use? what exactly does it do?

And I do think I found higher Aux to help maintain stability with memory OC slightly, but that might be placebo.. I dont use it anymore.
p.s. is it confirmed Tri-X are hynix only? That would be the first card to ever be hynix only, 79XX or R9 290(x)... I think even the Lightning 79XX came with Elpida and Hynix?
Just checked my tri-x, their Hynix, they easily reach 1500, 1600+ has been an bit of an struggle. I've only been using sapphire trixx which only has offset controls for core, no aux controls like afterburner.
I got around to making a nifty little chart for those interested in my findings for the TRI-X OC, I would love to get comparisons from other owners. Mostly concerned if these are normal VRM1 temps, thats the only thing worrying me. Runs great in AC4, gonna do some more testing for actual game performance.
About BF4, apparently Newegg is no longer offering it to all 290X as it was suppose to be. I'm gonna contact AMD and see if I can snag another code
