In this case yes, the mobo is compatible with LV (low voltage) memory, I know they tested with the 1.25 Snipers, though many mobos are not set for it (in particular older mobos and AMD ones)....the LV sticks are primarily out their as the DRAM manufactures work with new memory chips in prep for the release of DDR4 (was particularly noticeable recently, as NewEgg has had a number of promos where they have been packaging say a free 8GB sticks with mobos, CPUs etc, this allows the manufacturers to get some feed back on how the sticks perform, and no they aren't the same as 1.5, most LV use a different PCB and different chips, if they were the same as a 1.5 set of the same freq, they would be upwardly binned to higher freqs and could be sold at a much higher price, with many DRAM makers most are still in the experimental stage, GSkill has had low voltage out for quite awhile, just as they have had the higher freq DRAM out much longer than others, they basically are the innovation leader in DRAM
