This isn´t the first time HynixCFR have been used on cold, iirc, I saw result of most likely exactly this kit (same series) on Z77 before - it didn´t end the era of Samsungs and PSC then, and it doesn´t end it now - like before, excellent kit on cold might give you another alternative, which might end the madness at prices for PSC hopefully
Good job, shimizu
