OWC 64GB DDR3L 1600 ECC RDIMM kit

This OWC memory kit supplies 64GB across four 16GB DDR3L 1600 registered DIMMs. Each module runs at 1.35V with CL11 latency and 2Rx4 organisation. The kit is built for Supermicro SuperServer 6047R, 7047R, 8017R, 8027R and 8028B systems that require ECC registered memory.

Suits servers needing registered ECC DDR3L.

These modules are designed for workstation and server platforms that accept registered ECC DDR3L RDIMMs. They will not work in standard desktop computers that use unbuffered non-ECC memory. Builders who need unbuffered DIMMs or a different voltage should look at other memory types.

Registered ECC with 2Rx4 rank configuration

The registered ECC design with 2Rx4 ranking is the single specification that determines compatibility. Only systems that explicitly support registered ECC DDR3L RDIMMs at 1.35V can use this kit. Verify your Supermicro server documentation before purchase.

Questions about this item

Will the 240-pin DDR3L RDIMMs need any periodic cleaning or component replacement?

No moving parts or consumable components exist on these modules; the only maintenance is keeping the server air filters clean so airflow reaches the memory slots.

What limit appears first when the 1600 MHz CL11 ECC registered kit runs at full load continuously?

The DDR3L JEDEC voltage ceiling of 1.35 V caps sustained throughput before thermal throttling becomes a factor.

How much extra heat and power do the four 16 GB 2Rx4 modules add when the Supermicro server runs all day?

Each module draws only the standard 1.35 V DDR3L current, so total added heat is minimal and covered by the server's existing cooling design.
