Pros: Goes far beyond rated specs, works flawless.
Cons: None so far
Purchased this kit along with a ASUS Maximus IV Extreme. Has a wide range of possible configs, but are totally capable of 2133mhz 9-11-9-27 1T @ 1.65v. Also other configs could be 1866 8-9-8-24 1T @ 1.6, or 1600 7-8-7-20 1T @ 1.6v. Setting timings to default (9-11-10-27), they go far beyond 2200. For all this, I think this kit is one of the best on the market with hynix IC's. And they look extremely beautiful. Regards
