Decent memory, not had any of that b4.
I`d kinda liken buying a 2x kit to put in a 3x array `as` equiv to putting a single stick in a 2x array.
So.. with the emphasis of working 1.5v+ for an i7 setup, why sell it as a 2x ? Of course u can buy another stick.. but with all the unquantified differences, ur timings will require the massaging. And not being a kit, performance or compatability not guaranteed.
It`s always greater to have less voltage to work ur ddr3 in a 4 series mobo, as I`m almost sure all the "good" ones have a tremendous range of vdimm. So on the one hand u cut the voltage req to allow i7, and sell as a pair for non i7.
Could well be ofc, that moving forward, it`s just the case that all newer ddr3 they, and others, produce will be ~1.5v as standard.
Nice review, nice sticks.
