OCZ’s 500Mhz, 2GB dual channel kit, the EL DDR PC-4000 1024MB Gold Edition Dual Channel, performs well straight out of the box, and better once you overclock it.  Even better is the lifetime warranty that comes with it.  Red & Blackness Mods puts it through the paces, check out the review.
“Todays games have started to require more power and one of the main things is ram. 1Gb or ram is required these days and 2Gb is almost recommended. We got a 2Gb kit from OCZ called PC-4000 1024MB Gold Edition Dual Channel that seems to be a very nice kit with decently low timings and 500mhz memory. We are of course going to test these out vs some high performing 1Gb kits to see if there is any difference in performance. Overclocking is also an important point to many so we will be testing this with lower timings and really heat these sticks up to see how high they can go”
