OWC 32GB DDR3L 1600 ECC RDIMM

This 32GB OWC module is a 240-pin DDR3L 1600 PC3L-12800 CL11 registered DIMM with ECC. It operates at 1.35V and uses a 4Rx4 organisation. The part is listed as compatible with Supermicro X9QRi and X9SRD series motherboards. It is intended for server and workstation memory upgrades.

Suited for ECC registered platforms only

This memory fits workstations, servers, NAS systems and routers that require DDR3L ECC registered RDIMMs. It will not work in standard desktop computers that accept only unbuffered non-ECC modules. Builders who need unbuffered memory or a different voltage should look at other options. Mixing this registered stick with unbuffered memory is not supported.

Registered ECC with 4Rx4 organisation

The module is an ECC registered RDIMM with a 4Rx4 rank structure, a combination that the motherboard memory controller must support. If the target system requires unbuffered ECC or a different rank configuration, this module will not function. Verify the platform documentation for registered 4Rx4 DDR3L support before purchasing.

Questions about this item

Does the 4Rx4 rank layout require any specific slot population on the X9QRi or X9SRD boards?

The module is a single 32 GB 4Rx4 registered DIMM; follow the motherboard manual for rank-per-channel limits when populating slots.

What thermal headroom does the 1.35 V DDR3L module have when running continuously at 1600 MHz?

Operating at 1.35 V reduces power draw versus standard DDR3, and the JEDEC-compliant design is rated for sustained server workloads without a heat spreader.

How much power does the registered ECC DIMM draw under full load all day?

At 1.35 V the DDR3L registered module consumes less power than 1.5 V DDR3, helping keep system power lower during 24/7 operation.
