Recently we received two DDR3 kits, one from OCZ Technology and one from Patriot Memory. The kit from OCZ was their 4GB DDR3 12800 (DDR3 1600) Platinum Enhance Bandwidth product and Patriot sent us their 2GB Viper DDR3 15000 (DDR3 1866) kit. Both of these products were used in our recent review of the ASUS P5E3 Premium motherboard. We saw some rather interesting phenomena with both of these memory kits in that review so we have decided to review both of these kits comparatively in much more detail using the same test rig. Our goal is not only to give you a complete review of these two memory products, but to also answer the questions we alluded to in the beginning of this introduction.
