G.Skill Ripjaws X 4 GB (2x2GB DDR3-1333)

The G.Skill Ripjaws X 4 GB arrives as 2 modules of 2GB each with 4GB of DDR3 on board. Operating voltage sits at 1.35V. It is rated at 1333 MT/s with a CAS latency of 7, working out to a true latency of about 10.5ns.

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.
