Mushkin 996659es 2x2GB ES3-12800 Memory Kit
 

In this review I will test a new model of memory modules from Mushkin, with the code name 996659es, which have blue heatspreaders and are from their Essential product line. The modules will be tested in both stock and overclocking modes, using the recommended timings and voltage.
