System-Specific DDR4 Upgrade

This 4GB DDR4 module is built for the Lenovo Ideacentre 300S desktop. It uses a 288-pin DIMM form factor and runs at 2133MHz with CL15 timing. The stick is unbuffered, non-ECC and operates at 1.2V. It targets owners of compatible 2184-xxx and 2688-xxx systems needing a single-slot memory increase.

Sustained Operation Profile

The memory operates at a standard 1.2V without a heat spreader, relying on case airflow for thermal management. CL15 latency and 15-15-15 timings remain stable during continuous workloads. The 2Rx8 rank organisation supports consistent data throughput for everyday multitasking and office applications over long sessions.

Platform Capacity Limits

The supported Ideacentre 300S chassis provides two DIMM slots and a maximum memory ceiling of 8GB. This single 4GB stick occupies one slot, leaving one free for a matching module. Buyers needing more than 8GB total capacity or a four-slot configuration must choose a different platform.

Questions about this item

Does the 1.2V DDR4 module run hot or noisy when the Ideacentre 300S stays on all day?

The stick operates at the standard DDR4 voltage of 1.2V and has no heat spreader, so it adds minimal heat and makes no noise of its own.

What must the Lenovo Ideacentre 300S already have for this 288-pin DIMM to work?

The desktop needs a free DDR4 DIMM slot — the 300S provides two — and a BIOS that supports 2133MHz non-ECC unbuffered memory.

Will this CL15 2133MHz stick work alongside the original memory in a 2184-xxx or 2688-xxx model?

Yes, it matches the factory speed and timing, so it will run in dual-channel with the existing module up to the 8GB system maximum.
