Corsair Dominator GT 1866 4gb kit on Asus Crosshair IV?

[scazbala86]

From what I have read, these modules are not "recommended for use on phenom systems" as they cannot be validated to run at the full 1866 speed due to the phenom's memory controller, but even if I can't get them to run at 1866, they still run fine at 1333 or 1600 on a phenom? The reason I ask is because the dominator 1600 sticks are actually $30 more on newegg. There is a review on newegg for the 8gb kit that says they run at 1866 on a crosshair IV but I want to hear what all of you think before I drop $140 on em. Thanks for your help.

btw it would be paired with a phenom ii x4 970, and the crosshair iv can use up to 1866 on x4, but can use 2000 and 2133 on x6 procs

also, I know I can get cheaper kits and all that, but I want corsair dominator gt's for the quality, and underclocking to 1333 or 1600 them is ok with me.

Corsair's are great and the GT line is terrific, but only use MOBO {Certified} or RAM Mfg {Tested} RAM.

Wow, that answer was exactly what I was looking for, thank you, jaquith, you are the man.
