16GB ECC SODIMM for Server Laptops

This 16GB DDR4 3200MHz ECC SODIMM targets technicians upgrading IBM-Lenovo workstations that require error-correcting memory. The unbuffered 2Rx8 module runs at standard 1.2V and fits 260-pin slots in compatible mobile server platforms.

ECC Unbuffered 2Rx8 Organisation

The single specification that determines fit is the ECC unbuffered 2Rx8 organisation combined with CL22 timing at DDR4 3200 (PC4-25600). Systems expecting registered DIMMs, non-ECC modules or a different rank configuration will not accept this part.

Straightforward Slot Installation

Installation follows the standard SODIMM procedure: power off, open the memory door, align the 260-pin key and press until the side clips lock. The most common issue is purchasing this ECC module for a consumer laptop that only supports non-ECC memory, resulting in a no-post condition.
