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.

Questions about this item

How much heat or noise does the 1.2V DDR4 2133MHz CL15 SODIMM generate during continuous use?

The module runs at a standard 1.2V without a heat spreader, so it produces minimal heat and no audible noise during all-day operation.

What must my Lenovo Flex 4 already have for this 260-pin DDR4 SODIMM to work?

Your Flex 4 needs a free DDR4 SO-DIMM slot and a BIOS that supports 2133MHz CL15 unbuffered memory; the system ships with one socket and a 16GB maximum.

Will this 8GB DDR4 2133MHz stick run alongside the original 4GB module in my Flex 4?

Yes, it will operate in dual-channel mode at 2133MHz CL15 as long as the original module is also DDR4 2133MHz non-ECC unbuffered.
