Computer Memory Solutions CM10246417000SO 8GB DDR4 2133MHz CL15 1.2V 260-Pin SODIMM Lenovo Flex 4

System-Specific DDR4 SO-DIMM for Lenovo Flex 4

This 8 GB DDR4 module is built to match the Lenovo Flex 4 series, including part numbers 80SAxxxx and 80SBxxxx. It arrives as a single 260-pin SO-DIMM running at 2133 MHz with a CAS latency of CL15 and 1.2 V operation. The unbuffered, non-ECC design fits the platform’s single memory slot.

Steady-state behaviour at rated speed

The module operates at its JEDEC-standard 2133 MHz without overclocking, so thermal output and power draw remain consistent during extended workloads. With 15-15-15 timings and a 2Rx8 organisation, latency stays predictable whether the system is compiling code, streaming video or keeping dozens of browser tabs open. No heat spreader is fitted, relying on the notebook’s existing airflow.

The 16 GB ceiling that defines the upgrade

The Flex 4 platform supports a maximum of 16 GB across its sole SO-DIMM socket, so this 8 GB stick leaves room for one more identical module to reach the limit. Builders who need more than 16 GB total capacity must choose a different laptop platform. The part carries a limited lifetime warranty from Computer Memory Solutions when purchased directly.
