Patriot Viper 16 GB (2x8GB DDR3-1866)

The Patriot Viper 16 GB arrives as 2 modules of 8GB each with 16GB of DDR3 on board. It is rated at 1866 MT/s with a CAS latency of 10, working out to a true latency of about 10.7ns. Operating voltage sits at 1.35V. Once memory clears 3600 MT/s, frequency gains taper off, so the 16GB on offer here is the spec that counts for modern AAA titles.
