Manufacturer description

DDR2 is the next generation of DDR memory. DDR2 memory features faster speeds, greater bandwidth, lower power consumption and enhanced thermal performance. Although DDR2 modules are the same physical dimension as DDR modules, the plug-in connector configuration is different and as such DDR2 modules are not compatible with PCs requiring DDR modules, and vice-versa.

SpecPicks Verdict

SpecPicks scored Memory Master 2 GB DDR2 800MHz PC2-6400 Desktop DIMM Memory Modules using a rating × review-volume × price-fit model applied to published specs and reviews across the memory & ram category. PNY's memory & ram lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for memory & ram of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent.
