In Search of True DDR2 Bleeding Edge Memory

Wintec's (AMP) DDR2-667: 475 MHz When Overclocked

This Wintec module first achieved CL3.0 mode operation at an input voltage of 2.2 v; at lesser voltage levels it could only hit the slower CL4.0 mode. But the module put on a good show in our overclocking tests: 950 (475 MHz) is a good value - but at 8.1 GB/sec the data transfer rate while reading was merely average.
