Lenovo ThinkCentre M800 compatible memory kit

This 16 GB kit contains two 8 GB DDR4 DIMMs built for the Lenovo ThinkCentre M800 in small-form-factor or tower configurations. It uses 288-pin unbuffered modules running at 2133 MHz with a CAS latency of 15. The memory operates at 1.2 V and is non-ECC.

Steady throughput at rated speed

Under sustained workloads the modules maintain their 2133 MHz data rate and 15-15-15 timing without requiring a voltage increase beyond 1.2 V. The dual-rank 2Rx8 organisation supports the platform's maximum capacity of 32 GB across four sockets.

Verify slot count and current population

Before ordering, confirm how many of the four DIMM sockets are already occupied in your M800. The system accepts up to 32 GB total, so adding this 16 GB kit is only possible when at least two slots remain free.

Questions about this item

How much heat does the 1.2V DDR4 kit add when the ThinkCentre M800 runs continuously?

The modules run at 1.2 volts without a heat spreader, so they add minimal heat inside the SFF or tower chassis during all-day operation.

Does the Lenovo ThinkCentre M800 need a specific BIOS version or four free slots before I install these two 8 GB sticks?

The system has four DIMM sockets and supports up to 32 GB total; two sticks fit in any open pair of slots with no extra hardware required.

Will the CL15 2133 MHz timing work alongside the original memory already in my M800?

Yes — the kit matches the DDR4 2133 CL15 specification used by the M800, so it runs at the same speed and latency as factory modules.
