Server ECC RDIMM for Supermicro SuperBlade

This OWC 8 GB DDR3L 1600 CL11 registered DIMM is built for Supermicro SuperBlade 7127R, 7127RG, 7127RG3, 7142G and 7427R servers. It delivers 1.35 V ECC registered operation with a 1Rx4 layout on a 240-pin form factor. The module replaces Supermicro part numbers MEMDR380LHL07ER16, MEMDR380LSL10ER16, MEMDR380LSL14ER16 and MEMDR380LSV04ER16.

Suits blade-server upgrades only

Administrators expanding memory in the listed SuperBlade chassis can install this stick directly. Builders working on standard desktops, workstations without registered-DIMM support, or any system requiring unbuffered memory must choose a different module. Mixing registered and unbuffered DIMMs is not supported by this part.

Registered ECC is the deciding factor

This module is an ECC registered RDIMM, so it only functions in platforms that explicitly support registered memory with error correction. If your motherboard or blade requires unbuffered non-ECC or load-reduced DIMMs, this part will not work.
