OWC DDR3L 1600 ECC RDIMM kit

This OWC kit provides 32GB of DDR3L 1600 registered ECC memory in four 8GB modules. It is built for Supermicro SuperServer 1027 and 2027 series systems that require registered DIMMs. Workstations and servers needing error-correcting registered memory are the intended audience. Standard desktop computers cannot use these modules.

240-pin 1.35V registered design

Each module uses a 240-pin DDR3L form factor and operates at 1.35V without a heat spreader. The registered buffer reduces electrical load on the server memory controller. Mixing these registered DIMMs with unbuffered memory is not supported and will prevent the system from booting.

DDR3L platform limits

The DDR3L 1600 interface caps bandwidth at the PC3L-12800 data rate with CL11 latency. Older SuperServer platforms cannot exceed this speed or use later DDR generations. Buyers who need higher memory throughput or newer memory technology must choose a different server platform.

Questions about this item

Does the PC3L-12800 rating cap real-world speed at 1600 MT/s?

Yes, the PC3L-12800 specification defines a maximum data rate of 1600 MT/s for these DDR3L modules.

Will the 240-pin registered DIMMs fit the Supermicro 1027 and 2027 series slots?

The 240-pin DDR3L RDIMM form factor matches the memory slots on Supermicro SuperServer 1027B, 1027GR, 1027R, 1027TR and 2027GR systems.

What is the correct order to install the four 1Rx4 modules?

Populate the slots following the Supermicro server's channel layout, typically starting with the first slot of each channel, and ensure the registered DIMMs are fully seated before powering on.
