Corsair Dominator 4 GB (2x2GB DDR2-1066)

The Corsair Dominator 4 GB comes as 2 modules of 2GB each with 4GB of DDR2 on board. Operating voltage sits at 1.35V. It is specced for 1066 MT/s with a CAS latency of 5, working out to a true latency of about 9.4ns.

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.
