8GB DDR3L 1600 ECC RDIMM for Supermicro

This is an OWC 8GB DDR3L 1600 PC3L-12800 CL11 1Rx4 240-pin 1.35V ECC Registered RDIMM. It is designed as a system-specific upgrade for Supermicro SuperServer 8047R, 8048B, F617R2, F617R3 and F627G2 series. The module uses registered ECC technology intended for workstation and server environments. It replaces several Supermicro part numbers including MEMDR380LHL07ER16 and MEMDR380LSL10ER16.

Suits registered ECC server platforms only

This memory suits administrators upgrading or repairing the listed Supermicro SuperServer models that require DDR3L registered ECC DIMMs. It will not work in standard desktop computers that use unbuffered non-ECC modules. It also cannot be mixed with unbuffered memory in the same system. Buyers needing unbuffered DIMMs or a different DDR generation should look elsewhere.

Registered ECC with 1Rx4 organisation

The single specification that decides fit is the registered ECC design with 1Rx4 organisation at 1.35V. The motherboard must support DDR3L registered ECC RDIMMs in a 240-pin slot. If the platform requires unbuffered memory or a different voltage, this module will not be compatible.

Questions about this item

How much power does the 1.35V DDR3L module draw when the server runs continuously?

The module operates at 1.35V, which is the standard DDR3L voltage, so it draws less power than 1.5V DDR3 DIMMs under sustained load.

What must the system already have for this 240-pin ECC Registered RDIMM to work?

The motherboard must support DDR3L 1600 ECC Registered memory and provide 240-pin DIMM slots; it cannot accept unbuffered or non-ECC modules.

Can I mix this 1Rx4 CL11 stick with the existing Supermicro MEMDR380LHL07ER16 modules in my 8047R?

Yes, this module replaces Supermicro part numbers including MEMDR380LHL07ER16, so it matches the same 1600MHz CL11 1.35V registered specification.
