Designed for ThinkMate TWX-QS4-14R7

This 16 GB kit provides two 8 GB DDR5 UDIMM modules built for the ThinkMate TWX-QS4-14R7 tower server. The memory runs at 4800 MT/s with a CL40 latency and operates at 1.10 V. It uses major OEM Samsung, Micron or Hynix chips in a 1Rx8 configuration and carries no heat spreader.

DDR5 UDIMM limits for this platform

The server accepts non-ECC unbuffered DDR5 UDIMMs only, so registered or ECC modules will not work. The 288-pin form factor and 1.10 V voltage are fixed by the platform, and the maximum JEDEC speed supported is 4800 MT/s. Installing faster DDR5 will downclock to this ceiling, and mixing ranks or voltages can prevent the system from posting.

Upgrade path from lower-capacity DDR5

This kit replaces a single 8 GB module or a slower DDR5 kit to double usable capacity and enable dual-channel bandwidth. The jump is worthwhile when workloads exceed the memory ceiling of a smaller configuration, such as virtualisation hosts or database caches. It does not suit systems that require ECC protection or registered DIMMs.
