perfect
After testing many different types of similar-priced CL10 ram, I've found anything less than CL11 operation does not yield much if any performance benefit for my particular motherboard and seems to actually degrade performance a little bit, so I'm running these sticks at motherboard's 1866 defaults...
Two sticks of his stuff runs flawlessly on my M5A99FX Pro R2.0; motherboard; I'm able to both undervolt and overclock it should I choose to; The heatspreader isn't too tall and fits nicely underneath my Hyper212EVO; Price right now represents incredible value; PERFECT for the FX platform
None so far; Very solid feel and classy looks
