Server-grade DDR3L ECC RDIMM

This 32GB DDR3L 1600 module uses 4Rx4 registered ECC technology at 1.35V. It fits 240-pin slots in Supermicro X9DBU, X9DR3, X9DR7, X9DRD and X9DRE motherboards. The part is built for workstations, servers, NAS systems and routers that require registered memory.

Replaces unbuffered or lower-capacity DDR3L DIMMs

The jump is worth it when the platform demands registered ECC and cannot accept unbuffered modules. It also applies when a single 32GB stick reduces slot count compared to multiple smaller DIMMs. This memory will not work in standard desktop boards that lack registered-ECC support.

32GB single-module capacity

One DIMM delivers 32GB at PC3L-12800 CL11, giving headroom for virtualisation, large datasets or multi-user workloads. The limit appears when the board's maximum memory per slot or total channel population is reached, or when an application needs bandwidth beyond DDR3L 1600.

Questions about this item

Does the 240-pin DDR3L RDIMM fit the X9DR7 motherboard DIMM slots?

Yes, the module uses the standard 240-pin DDR3L RDIMM form factor that matches the DIMM slots on Supermicro X9DR7 series boards.

What BIOS setting or seating step is often missed when installing this ECC registered module?

Ensure the module clicks fully into the 240-pin slot and verify the BIOS reports 1.35 V operation; registered DIMMs will not post if seated loosely or if voltage defaults to 1.5 V.

When should the 32 GB 4Rx4 module be replaced in a server running continuous workloads?

Replace it if ECC correctable error counts climb steadily or if the system logs uncorrectable memory errors during sustained operation.
