You can pick up two DIMMs with the 16GB kit or four with the 32GB, either way you end up with DDR3-1866MHz @ 10-10-10-27 running on 1.5v, with a lifetime warranty to boot!  When Overclockers Club went to work the two kits did end up showing some difference as the 16GB kit hit 2288MHz @ 11-11-12-28 2T while the 32GB only managed 2202MHz @ 11-12-12-28 2T.  If you check out the Mushkin Redline series on NewEgg you will see a wide variety of models, so pick the ones with the lowest latency for the best performance out of the box as well as more overclocking headroom.

"Looking at these two kits of memory from Mushkin shows that it has another pair of kits that deliver performance indicative of their specifications and more. First up are the distinctive good looks and functionality of the cooling solutions employed on each kit. The 32GB kit part number 994071 uses the "Ridgeback" design. This robust heatsink package uses a series of angle shaped (think Mushkin logo) fins on top of a thick body to effectively wick away the thermal load generated by these high density modules. Packing them into a four DIMM configuration like used in the testing will allow a higher heat load to be retained but is nothing to be concerned about. Using an air cooled CPU cooling solution would fix that issue as once air starts moving over the modules they cool down fast."
