16GB DDR4-2400 ECC Registered DIMM

This 16GB DDR4-2400 module is a low-profile ECC Registered DIMM built for server platforms that require error-correcting memory. The 1Rx4 organisation and 1.20V operating voltage suit dense multi-DIMM configurations in qualified systems. It carries Supermicro certification under part MEM-DR416L-SL02-ER24.

Upgrade from non-ECC or unbuffered memory

The jump is worth it when the workload demands data integrity across large memory arrays and the motherboard chipset requires registered modules. Standard unbuffered or non-ECC DIMMs will not function in these slots and mixing registered with unbuffered memory prevents boot.

Install into 288-pin DDR4 slots

Align the key notch with the slot and press evenly until the retention clips engage; the low-profile height eases clearance in tight chassis. Common issues include populating slots in the wrong order for the specific platform, leaving a clip unlatched, or mixing ranks in a way the memory controller rejects.

Questions about this item

Will this 288-pin DDR4 module fit my server's low-profile DIMM slots?

Yes, the LP (low-profile) design uses the standard 288-pin DDR4 form factor and is built to clear tight spaces in 1U or blade chassis.

What is the correct way to seat this registered ECC stick so the server recognises all 16 GB?

Align the off-centre notch with the slot key, press straight down until both retention clips click, and populate slots per the motherboard manual — registered modules often require specific bank order.

When should I plan to replace this 1Rx4 registered ECC memory?

ECC corrects single-bit errors on the fly; replace the module only if the system logs uncorrectable errors or fails memory diagnostics during scheduled maintenance.
