16GB DDR4 2133 ECC UDIMM for server upgrades

This 16GB DDR4 2133 ECC UDIMM module provides 16GB of error-correcting memory for compatible server or workstation systems. It operates at 2133MHz with a CL15 latency and standard 1.2V voltage. The unbuffered design suits platforms that require ECC UDIMM rather than registered DIMMs.

Verify DDR4 UDIMM support

Confirm that your motherboard accepts DDR4 ECC UDIMM modules and provides 288-pin DIMM slots. Check the system documentation for maximum capacity per slot and supported speeds to ensure the 2133MHz PC4-17000 specification matches the platform requirements. Ensure the board does not require registered or load-reduced memory instead.

Major-brand chips on a standard 288-pin PCB

The module uses major-brand chips assembled on a 288-pin DDR4 DIMM PCB with 2Rx8 organisation. The gold-edge connector fits any standard DDR4 UDIMM slot keyed for 1.2V operation. No extra heatsinks or tall components protrude, so the stick clears typical CPU coolers and dense multi-slot layouts in rackmount chassis.

Questions about this item

What comes in the box and is anything else needed to install this 16GB DDR4 2133 ECC UDIMM?

The box contains one 16GB DDR4 2133 ECC UDIMM module with 288 pins. No extra parts are required; the module plugs directly into a compatible DDR4 UDIMM slot.

Should I choose a different capacity or speed for my IBM-Lenovo system that uses part numbers like 46W0819 or 00NU565?

This module matches the 16GB DDR4 2133 specification for those IBM-Lenovo part numbers. Select a different capacity only if your system documentation calls for a different size.

How does the CL15 latency and 1.2V voltage affect real-world server performance with this ECC UDIMM?

CL15 at 2133 MHz provides standard DDR4 timing for reliable data integrity, while 1.2V is the normal DDR4 voltage, keeping power draw and heat at expected levels for continuous server operation.
