if your overclocking the module
i would go with muskin, if not, corsair. muskin would take more abuse
than corsair and still be stable back when i was into that sort of thing
. i am running corsair xms 800mhz no overclock now
. had many corsair modules that i traded or left with different machines and never a bad one (other than frying lightly brown on both sides) if i didnt overclock them.
