Of the two you have listed I would go for the Corsair. I have that kit in mine and it does well and I like the low profile of the ram which won't interfere with large heat sinks.
Before I got the Corsair kit I tried a 1600 cas6 Mushkin set of low latency ram that wouldn't run stable at 1600 or above no matter the timings. So I looked at the QVL list for the board and the Cosair was listed. It will run 1750 or so cas8 with decent voltages (qpi/vtt under 1.4) and rated voltage for the ram. The thing with the high speed ram they don't tell you is at what qpi/vtt it needs to run that speed which can be as high as the ram itself which is too high for me to feel safe for 24/7 use.
Here is a hot of the Everest memory bench at 1725
and a shot of it installed and under my VX.
