16GB DDR3L ECC Registered DIMM

This 16GB DDR3L module runs at 1600 MT/s with CL11 latency and 1.35V operation. It uses a 240-pin registered ECC design built for Supermicro SuperServer 4047R, 4048B, 5017GR, 5017R and 5027R series. The 2Rx4 organisation suits multi-socket server boards that require registered memory.

Replaces standard unbuffered DDR3

Swapping unbuffered DIMMs for this registered ECC module adds error correction and signal buffering for stable 24/7 server workloads. The jump is worth it when your Supermicro platform specifies registered memory and you need 16GB per slot at DDR3L 1600 speed.

Verify your Supermicro model

Confirm the exact SuperServer series matches the supported list before ordering. Registered ECC DIMMs cannot be mixed with unbuffered memory in the same system. Check the board manual for maximum modules per channel and approved rank configurations.

Questions about this item

Will this 240-pin DDR3L DIMM fit the memory slots on my Supermicro SuperServer 5027R?

Yes. The module uses the standard 240-pin DDR3L form factor required by the 5027R and the listed 4047R, 4048B, 5017GR and 5017R series.

What is the correct way to install this registered ECC module, and what mistake should I avoid?

Power down the server, open the chassis, align the notch on the 240-pin edge connector with the slot key, and press firmly until both retention clips click. Do not mix this registered DIMM with unbuffered memory.

When will this 16 GB DDR3L 1600 CL11 module need replacement or maintenance?

The memory itself has no moving parts and requires no scheduled maintenance. Replace it only if diagnostics report correctable ECC errors that become uncorrectable or if a slot fails.
