16GB DDR4 ECC Registered RDIMM

This 16GB DDR4 2400MHz CL17 ECC Registered RDIMM operates at 1.2V with a 288-pin interface. It is designed for server and workstation platforms that require registered memory with error correction. The module uses a 2Rx8 rank configuration and has no heat spreader.

Suits Supermicro X10DR motherboards only

Compatible with Supermicro X10DRFF-ITG, X10DRFR, X10DRG-H, X10DRH-C and X10DRFR-T motherboards. It will not work in standard desktop computers or systems that require unbuffered non-ECC memory. Builders needing unregistered DIMMs or consumer DDR4 speeds should look elsewhere.

Registered ECC requirement decides fit

The module is registered ECC DDR4 2400MHz CL17; the system must support registered ECC RDIMMs at this speed and latency. If the platform only accepts unbuffered or non-ECC memory, this part will not function.

Questions about this item

What slot type and pin count does this 288-pin DDR4 RDIMM require on the Supermicro X10DRFR motherboard?

It installs into a standard 288-pin DDR4 DIMM slot on the listed Supermicro X10 series boards.

Which orientation notch and keying should I align when seating this registered ECC module?

Align the single off-centre notch on the module edge connector with the key in the 288-pin DDR4 slot, then press straight down until both retention clips click.

When should this 16 GB 2Rx8 RDIMM be replaced in a server workload?

Replace the module if system logs show increasing correctable ECC error counts or if a full memory diagnostic reports uncorrectable failures.
