Kingston KHX6400S2ULK2/4G 4 GB (2x2GB DDR2-800)

The Kingston KHX6400S2ULK2/4G 4 GB ships as 2 modules of 2GB each with 4GB of DDR2 on board. Operating voltage sits at 1.35V. It is rated at 800 MT/s with a CAS latency of 4, working out to a true latency of about 10ns. Once memory clears 3600 MT/s, frequency gains taper off, so the 4GB on offer here is the spec that counts for esports and everyday use.
