DDR3-1866 memory modules are tested to be fully compatible with Intel Romley-EP platforms based on Intel's latest generation server processor, the Xeon E5-2600 v2 family. Each module is rated at 1866MHz with latency of 13-13-13 and an operating voltage of a mere 1.5V. Additionally, Transcend's DDR3-1866 server DIMMs feature built-in ECC function, which monitors data being transferred in and out of memory and corrects any errors found.
