Corsair Dominator GTX1 PC3-19200 4GB Kit Review

"Like the 2250MHz DDR kit, this memory is bought by the piece. Unlike the GTX2 2250MHz DDR modules, though, this is a kit designed for the P55 platform instead of the P55 and X58. If high performance memory is what you're after and you're on an X58 machine, then the GTX2 kit is what you're going to want.

On the other hand, if you're running a P55 you have to decide if you want slightly lower clock speeds with more aggressive timings or higher clock speeds with more relaxed timings. If it was me personally, I would opt for the GTX2 kit, but that's only because I was able to achieve 2350MHz DDR on that kit. Since we can't guarantee you would have the same luck, if raw MHz is what you're after then the GTX1 kit we're looking at today is going to be a better option."
