Necrobumping for info, I still haven't seen anything G.Skill besides early 2013 that has G-Die in it. Also, 2800 tRP 12 seems to be a surprisingly difficult bin category.
Semi related, G-Die has been documented in 1600C8 Trident by @Apfelkuchen. He also saw a listing for 1333C7 Ripjaws that was very likely to be G-Die but seller fell silent. Both B63, by the way.
Speaking of, G-Die seems to have weird PCB sensitivity. Sticks on B63 have documented 1t weakness when on 4-dimmers, but appears to behave as good or better than non-ECC Samsung PCB when with 2-dimmers.
