OWC 32GB (4x8GB) DDR3 1600 CL11 1Rx4 240-pin 1.5V ECC RDIMM Kit for Supermicro 1027GR

Targeted Server Upgrade

This 32GB kit contains four 8GB DDR3 1600 registered ECC modules built for the Supermicro SuperServer 1027GR series. It replaces Supermicro part MEMDR380LSL04ER16 and is validated for workstation, server, NAS and router platforms that require registered memory. Standard desktop systems cannot use these modules and they must not be mixed with unbuffered DIMMs.

Thermals and Power

Operating at 1.5V with a CL11 latency, the modules run within standard DDR3 power limits for registered server memory. No heat spreaders are fitted, so airflow through the chassis handles cooling without added noise. The registered buffer reduces electrical load on the memory controller, helping maintain stable operation under sustained workloads.

Upgrade Context

The kit suits administrators extending the service life of a 1027GR chassis or building a replacement server on a budget. Buyers who need unbuffered memory, a different voltage, or a higher speed grade cannot use this product. Capacity is fixed at 32GB across four slots, so systems requiring larger per-module densities or a different slot count will need an alternative solution.
