LED is absolutely right about the list (I'd bet you won't find anyone in the forums that disagrees). In fact, they're almost exactly at the tops of their respective tiers. For example, the best RAM for overclockers are Samsung, Corsair, Mushkin, Geil, and OCZ. The next tier is the quality RAM that doesn't usually overclock as well, such as Kingston, Crucial, and TwinMOS (though they don't OC too poorly). The last tier is the generic RAM. PNY is about as good a brand as you'll find in the generic RAM corner. House brands and such are included in that tier.Originally posted by: LED
IMO:
1) Samsung
2)Kingston
3)PNY
and this all matters on which grade of Mem you purchase from them
