Noone knows for sure which type of Hyper the GTX2 are (Corsair HS are very difficult to remove + GTX2 are very expensive and rare). Hyper compatibility sucks with Ivy, even if you have GTX2 (hence you see people selling them a lot).
BTW, I think that other memory is used (most likely PSC), 7-10-7 is not the sort of Hyper timings
