Patriot Memory PC3-15000 2GB Dual Channel Kit
 

Our latest sticks come to us via Patriot and sport a PC2-6400 sticker on them, they also have this nifty little stamp "RoHS Compliant", while not a big deal (yet) in the US, in European countries, without it, it means you can't even sell it. The most important aspect that I can see of RoHS Compliance, is that the gear must be built without any lead whatsoever.
