16 GB DDR4 SO-DIMM runs at 3200 MHz with CL22 latency and ECC for server stability
This 16GB DDR4 SO-DIMM operates at 3200 MHz with CL22 timings and 1.20V voltage. It uses a 260-pin form factor and includes ECC for data integrity in server workloads. The module is built with Micron R-die chips in a 2Rx8 configuration without a heat spreader.
Ideal for systems that need registered error correction in a compact SO-DIMM slot. Not for desktop boards that only accept non-ECC UDIMMs or laptops lacking ECC support in the BIOS. Builders needing higher capacity per slot or lower latency timings should evaluate other modules.
The single specification that decides fit is the DDR4 3200 CL22 ECC 2Rx8 260-pin SO-DIMM standard. Verify your platform accepts ECC SO-DIMMs at this speed and rank configuration before purchase. The 1.20V JEDEC voltage matches mainstream DDR4 server requirements.

The module operates at 1.20 V, the standard voltage for DDR4 SO-DIMMs; actual power draw varies with workload and platform but remains within normal DDR4 limits.
It needs a 260-pin DDR4 SO-DIMM slot supporting DDR4 3200 (PC4-25600) with ECC capability; the system must also accept 2Rx8 registered or unbuffered modules depending on platform.
The module runs at 3200 MHz with CL22 latency; when mixed with slower DDR4, the system typically downclocks all memory to the lowest common speed and loosest timings.
