Kingston KVR1333D3/4GR 4 GB (1x4GB DDR3-1333)

The Kingston KVR1333D3/4GR 4 GB comes as a single module with 4GB of DDR3 on board. Operating voltage sits at 1.35V. It is rated at 1333 MT/s with a CAS latency of 9, working out to a true latency of about 13.5ns. 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.
