..you mean the kind that doesn't make your caps lock button stick?
Doesn't matter that much - Regardless of branding, manufacturers buy the source chips from the same few manufacturers (Micron being a well known example)
, and even switch vendors depending on factors like availability and which happens to be cheapest at the time. Honestly, on the desktop RAM speed doesn't matter either, except insofar as needed to support whatever combination of buss speeds for whatever overclock you have planned.
So buy whatever's on sale from a reputable maker and be done with it.
