G.Skill F2-4200PHU1-1GBSA 1 GB (1x1GB DDR2-533)

The G.Skill F2-4200PHU1-1GBSA 1 GB comes as a single module with 1GB of DDR2 on board. It is rated at 533 MT/s with a CAS latency of 4, working out to a true latency of about 15ns. Operating voltage sits at 1.35V. Once memory clears 3600 MT/s, frequency gains taper off, so the 1GB on offer here is the spec that counts for esports and everyday use.
