Corsair XMS2 4 GB (2x2GB DDR2-800)

The Corsair XMS2 4 GB ships as 2 modules of 2GB each with 4GB of DDR2 on board. Operating voltage sits at 1.35V. It is specced for 800 MT/s with a CAS latency of 5, working out to a true latency of about 12.5ns. 4GB gives you enough headroom for esports and everyday use; past 3600 MT/s, extra frequency brings diminishing returns.
