16GB DDR4 2133MHz ECC SODIMM

This 16GB DDR4 2133MHz ECC SODIMM module adds error-correcting memory capacity to compatible laptops and workstations. It runs at PC4-17000 speed with CL15 latency and standard 1.2V operation. The 260-pin form factor fits DDR4 SO-DIMM slots in systems that require unbuffered ECC memory.

Sustained workload stability

ECC circuitry detects and corrects single-bit errors during continuous operation, reducing the chance of data corruption in server and workstation tasks. The unbuffered design keeps latency low while the major-brand chips maintain consistent timing under load. Voltage remains at 1.20V for efficient thermal behaviour during extended sessions.

Straightforward slot installation

Align the notch on the 260-pin edge connector with the key in the SO-DIMM slot and press until the retention clips engage. The module height follows the standard DDR4 SO-DIMM profile for most chassis. Systems that do not support ECC or require registered DIMMs will not recognise the module.

Questions about this item

How much power does the 1.2V DDR4 module draw when the laptop runs all day?

The module operates at the standard DDR4 voltage of 1.2V, keeping power draw low during continuous use.

What must my system already support for this 260-pin ECC SODIMM to function?

Your laptop or workstation must accept DDR4 2133MHz ECC unbuffered SO-DIMMs and provide a 260-pin slot.

Will this CL15 16GB stick work alongside the original 03X7052 module I am keeping?

Yes, it is a compatible equivalent for the IBM-Lenovo 03X7052 part, so it can run beside that module.
