Hypers have become obsolete. Everybody still has them but nobody wants them anymore. Pretty sure everybody was expecting this ram to have a very long lifespan as it could run very tight timings at reasonable speeds.

What do we see now? Samsung and Hynix at cas 9, 10 and even 11. From what i've heard, Haswell will be no different so i reckon we will stick to this loose timings mem a while longer.

I don't know what Piledriver prefers but i'm about to find out.
