Server-grade DDR4 ECC RDIMM

This OWC module provides 16 GB of DDR4 2400 memory with ECC and registered buffering. It is built for Supermicro X10SDV motherboards used in servers, workstations and NAS systems. The CL17 timing and 1.2 V operation meet JEDEC PC4-19200 specifications.

Verify registered ECC support before ordering

Your motherboard must accept 288-pin DDR4 registered ECC RDIMMs; standard desktop boards that use unbuffered memory will not work. The module is a 2Rx8 configuration and cannot be mixed with unbuffered DIMMs. Confirm the exact X10SDV model matches the listed compatible part numbers.

Low-voltage operation keeps thermals modest

At 1.2 V the DIMM draws minimal power and generates little heat during typical server workloads. No heat spreader is fitted, so airflow across the memory slots handles cooling silently. Registered buffering adds negligible latency while maintaining signal integrity for stable 24/7 operation.

Questions about this item

Does the 288-pin DDR4 RDIMM arrive as a single 16 GB module or do I need to order multiple sticks to reach that capacity?

The part number 2R4D42R816GB represents one 16 GB registered DIMM; no additional modules are required to obtain the stated capacity.

Should I choose this CL17 2400 MHz ECC registered kit or a lower-latency unbuffered alternative for my Supermicro X10SDV board?

The X10SDV series requires registered ECC memory; unbuffered DIMMs will not work, so this CL17 2400 MHz module is the correct type.

Will the PC4-19200 2400 MHz rating deliver that full bandwidth once installed in a Supermicro X10SDV-TLN4F?

The motherboard's memory controller supports DDR4-2400, so the module will operate at its rated 2400 MHz / PC4-19200 speed.
