16 GB DDR3L ECC RDIMM for Dell PowerEdge

This 16 GB DDR3L 1600 CL11 registered DIMM is built for Dell PowerEdge M420, M520, M620, M820 and M915 servers. It delivers ECC error correction and registered buffering for stable operation in multi-module configurations. The module runs at 1.35 V and uses a 240-pin form factor. It replaces several Dell part numbers including A6761613 and SNP20D6FC/16G.

Check your server before ordering

Verify that your PowerEdge model is listed above and that the system accepts DDR3L registered ECC memory. The module cannot be mixed with unbuffered DIMMs and will not work in standard desktop platforms. Confirm the memory slot population rules in the server documentation to match rank and voltage requirements.

Suited for IT teams maintaining listed PowerEdge

Ideal for administrators extending the life of compatible Dell blade servers or building cost-effective replacements. Not suitable for desktop PCs, laptops or consumer motherboards that require unbuffered non-ECC memory. Buyers needing higher capacities per module or different DDR generations should look elsewhere.

Questions about this item

Does the 240-pin DDR3L ECC RDIMM arrive as a single 16 GB module or do I need to buy anything else?

The box contains one 16 GB DDR3L 1600 CL11 2Rx4 240-pin 1.35 V ECC Registered RDIMM. No extra cables, brackets or software are required; just an available DIMM slot in a compatible server.

My Dell PowerEdge M620 has several empty slots — should I add one 16 GB stick or two 8 GB sticks?

This part is a single 16 GB 2Rx4 module. If your M620 supports 2Rx4 population rules, one module fills a slot and leaves room for future expansion; matching 8 GB pairs are a separate SKU not covered here.

What does the PC3L-12800 1600 MHz rating actually deliver inside a PowerEdge M820?

The module runs at 1600 MT/s with CL11 latency at 1.35 V, providing ECC error correction and registered buffering for stable operation in the M820’s memory controller.
