OWC DDR3L ECC Registered Kit

This OWC kit supplies 16GB of DDR3L memory as two 8GB registered DIMMs built for the Dell PowerVault NX400. Each module runs at 1600MHz with CL11 latency at 1.35V and includes ECC error correction for data integrity in server workloads. The 240-pin form factor matches the system's memory slots exactly.

Suited for NX400 capacity upgrades

Administrators expanding a PowerVault NX400 to its supported memory ceiling will use this matched pair. It is not suitable for standard desktop PCs or consumer motherboards that require unbuffered non-ECC modules. Buyers needing higher densities per slot or a different DDR generation must select alternate parts.

Steady throughput under load

Registered buffering reduces electrical load on the memory controller during sustained read and write cycles. ECC correction operates continuously without halting the bus when single-bit errors occur. The low 1.35V operating voltage limits thermal output during extended operation in the NX400 chassis.

Questions about this item

What server must I already have to install this 240-pin DDR3L 1600 RDIMM kit?

The kit is validated for the Dell PowerVault NX400 and replaces Dell part numbers A7134886, A7545680, RKR5J and SNPRKR5JC/8G.

Can I keep my existing unbuffered DDR3L modules and add these registered DIMMs?

No. The manufacturer states registered memory cannot be mixed with unbuffered memory; all slots must use registered ECC modules.

How do I confirm the kit is running at PC3L-12800 CL11 after installation?

Check the system BIOS or iDRAC memory inventory; it should show 16 GB total at 1600 MHz, 1.35 V, CL11, registered ECC.
