Dell PowerVault NX400 memory upgrade

This 16 GB DDR3L ECC registered DIMM is built for the Dell PowerVault NX400 storage server. It delivers 1600 MHz speed with CL11 latency at 1.35 V, adding capacity for virtualisation, file services or backup workloads. The module replaces Dell part numbers A6761613, A6994465, A7515505, A8255125 and SNP20D6FC/16G. Buyers who need unbuffered desktop memory cannot use this product.

240-pin registered ECC build quality

The stick uses a 240-pin DDR3L form factor with 2Rx4 organisation and no heat spreader, fitting directly into the server's registered DIMM slots. ECC and registered signalling protect data integrity in always-on environments, while the low-voltage 1.35 V operation matches the platform's power envelope. Mixing this module with unbuffered memory is not supported and will prevent boot.

Verify slot count and population rules

Confirm the PowerVault NX400 has free registered DIMM slots and check the system's maximum supported capacity per slot before ordering. The motherboard must accept 16 GB registered modules at DDR3L 1600; some configurations limit rank population or total memory. Buyers who need higher-density modules or a different voltage should not purchase this kit.

Questions about this item

What speed does the DDR3L 1600 PC3L-12800 interface actually run at in the Dell PowerVault NX400?

The module is rated for DDR3L 1600 (PC3L-12800) and will operate at that speed when the server's memory controller supports it.

Does the 240-pin ECC Registered RDIMM fit the Dell PowerVault NX400 memory slots without a riser?

Yes, the 240-pin DDR3L form factor matches the NX400 DIMM sockets directly; no riser or adapter is needed.

What is the correct installation sequence for this 2Rx4 registered module in the PowerVault NX400?

Power down the server, open the chassis, align the notch on the 240-pin RDIMM with the slot key, press firmly until both latches click, then power on. People often forget to fully seat both latches.
