Capacity and fit

This 48GB kit ships as six 8GB DDR4 ECC UDIMMs rated at 3200 MT/s with CL22 timing. It is built for ThinkMate TWX-XS4-14W3 tower servers that accept unbuffered 288-pin modules. Buyers needing registered DIMMs or higher-density sticks cannot use this kit.

Headroom at 3200 MT/s

The PC4-25600 bandwidth handles typical virtualization, file-serving and database workloads on the target platform. Six single-rank 1Rx8 modules populate every slot on many ThinkMate boards, so further expansion requires replacing the kit. CAS latency of 22 is standard for this speed grade.

Build and daily use

Modules use major OEM Samsung, Micron or Hynix chips and run at 1.20V without heat spreaders. The bare green PCB fits tight server DIMM spacing and relies on chassis airflow for cooling. ECC protection corrects single-bit errors to keep the tower running through long uptime cycles.

Questions about this item

Will these DDR4 3200 ECC UDIMM modules run alongside older DDR4 sticks already in my ThinkMate server?

All six modules are DDR4 3200 PC4-25600 CL22 1.20 V unbuffered ECC; mixing speeds will force the system to run at the lowest common speed and may disable ECC if the other sticks are non-ECC.

How can I confirm the kit is operating at 3200 MHz with ECC active after installation?

Check the BIOS memory information screen or run a tool such as dmidecode — it should show 3200 MT/s, CL22, 1Rx8 organisation and ECC enabled for each of the 288-pin slots.

What exactly ships in the box and is anything else required to install the 48 GB kit?

The package contains six 8 GB DDR4 3200 ECC UDIMM modules (part ME25600-818K6); no heat spreaders, cables or tools are included, and no additional parts are needed for a standard 288-pin DIMM slot.
