Server ECC RDIMM upgrade

This OWC module is an 8 GB DDR3L 1600 ECC Registered DIMM built for Supermicro SuperServer platforms. It targets administrators extending the life of 4047R, 4048B, 5017GR, 5017R or 5027R systems. It is not suitable for standard desktop motherboards or any board that requires unbuffered memory.

240-pin DDR3L form factor

The stick uses the industry-standard 240-pin DDR3L layout and operates at 1.35 V, so it fits the registered DIMM slots in the listed SuperServer chassis. No heat spreader is present, allowing tight slot spacing in 1U and 2U enclosures. Mixing this registered module with unbuffered DIMMs will prevent the system from posting.

CL11 latency at PC3L-12800

The single specification that decides fit is the CL11 timing at the PC3L-12800 data rate; the server BIOS must support this exact speed and latency combination. Buyers whose platforms demand a different CAS value or a higher-ranked configuration cannot use this module.

Questions about this item

Does the PC3L-12800 DDR3L 1600 standard cap the module at CL11 latency?

Yes, the module runs at DDR3L 1600 (PC3L-12800) with a CAS latency of CL11.

Will the 240-pin registered DIMM fit a Supermicro 5027R server board?

The module is a 240-pin DDR3L ECC registered DIMM validated for Supermicro SuperServer 5027R series.

What is the correct installation sequence for registered ECC modules in these servers?

Populate slots per the server manual; registered DIMMs must not be mixed with unbuffered memory.
