Pros: I built 2 comps. with this memory both with 2600k on asus P8Z68 Deluxe. Computer did not post with XMP set to 2133. Did boot when on auto @ 1600, installed windows then manually set @ 2133 with other tweaks in bios. All memory above 1600, according to Asus will run on OC'd comps.

Cons: none, this memory keeps on trucking.

Overall Review: refrain from setting voltage above 1.5v, the memory controller is on cpu instead of northbridge and could fry the cpu.

Pros: None. 1 egg minimums, else 0 egg!

Cons: Died after a week or so.

Overall Review: Not recommended!
