ECC Registered DDR3L kit for Supermicro X9

This OWC kit supplies 64 GB of DDR3L 1600 memory across four 16 GB registered DIMMs. It is built for workstations, servers and NAS systems that require ECC error correction and registered buffering. Standard desktop platforms cannot use this memory, and it must not be mixed with unbuffered modules.

Fits Supermicro X9QRi and X9SRD motherboards

Each module uses the 240-pin DDR3L form factor and runs at 1.35 V, matching the voltage and pin layout of the listed Supermicro boards. The four-DIMM arrangement fills a quad-channel configuration on supported platforms, freeing the remaining slots for future expansion if the board provides more than four sockets.

Low-voltage DDR3L reduces heat output

Operating at 1.35 V lowers power draw compared with standard DDR3, helping keep system thermals manageable in dense server chassis. The modules carry no heat spreader, so airflow across the DIMM rows handles cooling. Registered buffering adds a small latency penalty but improves signal integrity on heavily loaded memory buses.

Questions about this item

What is the maximum total capacity supported by the X9QRi or X9SRD motherboards with this kit?

The kit provides 64 GB across four 16 GB modules, matching the 240-pin DDR3L 1600 specification for these Supermicro boards.

How much power do the four registered DIMMs draw at 1.35 V during continuous operation?

Each module runs at 1.35 V DDR3L voltage; registered ECC RDIMMs typically draw a few watts per stick, so the full kit stays within standard server memory power envelopes.

Which motherboard series must already be installed for these 240-pin DDR3L RDIMMs to function?

The memory is validated for Supermicro X9QRi and X9SRD series motherboards that accept 240-pin DDR3L ECC registered DIMMs.
