OCZ PC4000 2GB EB Platinum Ed
 

Gone are the days when the best performance is provided by 1GB kits
of memory. OCZ has given us an alternative that provides amazing
performance, solid overclockability, and 2GBs of memory in the form of two
1GB modules running in dual channel at timings that are un-heard of anywhere
else on the market. As you saw from the overclocking, this kit not only runs
DDR500 @ 3-3-2-8 but it actually runs DDR500 @ 2.5-3-2-7 and 2-3-2-7 up to
DDR450+!
