8GB DDR4 2133MHz upgrade for ThinkCentre M700 M800

This 8GB DDR4 2133MHz CL15 module is built for Lenovo ThinkCentre M700 SFF, M800, M900 and S510 desktops. It uses a 288-pin unbuffered non-ECC UDIMM design that matches the factory specifications for those systems. The 1.2V operating voltage keeps power draw low while adding capacity.

JEDEC and RoHS compliance plus lifetime warranty

The module meets JEDEC standard PC4-17000 timing and is RoHS compliant, so the upgrade does not void the original system warranty. OWC includes a limited lifetime warranty with free technical support and an advanced replacement programme. No extra software or cables are bundled with the memory stick.

Verify slot count and maximum supported memory

Confirm how many DIMM slots your specific ThinkCentre model provides and what total memory the motherboard and BIOS allow. The M700 SFF chassis may have fewer slots than the tower versions. Systems already populated to the maximum cannot accept this 8GB module without removing existing sticks.

Questions about this item

Will the 2Rx8 rank layout on this 8GB DDR4 module ever require a firmware update or replacement?

The 2Rx8 rank configuration is a fixed hardware characteristic of the module and does not require firmware updates or scheduled replacement under normal operation.

What limit appears first when this CL15 2133MHz memory runs sustained workloads?

The CL15 latency at 2133MHz sets the throughput ceiling; sustained use will hit this timing boundary before thermal or voltage limits become a factor.

How much heat or noise does the 1.2V unbuffered DIMM produce during all-day operation?

Running at 1.2V without a heat spreader, the module generates minimal heat and zero audible noise, relying on case airflow for passive cooling.
