Targeted Server Upgrade

This 64GB kit contains four 16GB DDR3 1600 ECC Registered RDIMMs built for Supermicro X9SRG, X9SRH, X9SRi, X9SRL and X9SRW motherboards. It is intended for workstations, servers, NAS systems and routers that require registered error-correcting memory.

Straightforward Module Installation

Each 240-pin DIMM seats in a standard DDR3 slot at 1.5V with CL11 timing. The registered buffer adds electrical load, so the motherboard must support registered memory; mixing these modules with unbuffered DIMMs will prevent the system from posting.

For Registered Memory Platforms

This kit suits administrators expanding compatible Supermicro servers or replacing Supermicro part numbers MEMDR316LSL03ER16 and MEMDR316LSV01ER16. It is not for standard desktop computers, laptops or any platform that accepts only unbuffered non-ECC memory.

Questions about this item

How do I verify the 64GB DDR3 1600 ECC Registered kit is detected correctly after installation?

Enter the system BIOS or UEFI on the Supermicro X9SRG, X9SRH, X9SRi, X9SRL or X9SRW motherboard and confirm the total memory shows 64GB at 1600MHz with ECC active.

What is included in the OWC 1R6D32R4064S package and what must be purchased separately?

The kit contains four 16GB 240-pin DDR3 1600 CL11 1.5V ECC Registered RDIMM modules; no additional parts are required for a compatible Supermicro server board.

Which capacity version of this OWC DDR3 ECC Registered memory should I choose for my Supermicro X9 series motherboard?

This part number provides 64GB as a matched 4 x 16GB kit; select it when your board supports that total capacity and you need registered ECC modules.
