Kingston 16GB DDR4 2133 ECC DIMM

This 16GB DDR4 2133 ECC unbuffered DIMM is built for specific Lenovo ThinkServer and ThinkStation models. It uses a 288-pin form factor and runs at PC4 17000 speed without a heat spreader. The module is designed and tested to meet JEDEC standards and includes free technical support.

Suits Lenovo TS150 TS450 P310 only

This memory fits the Lenovo ThinkServer TS150, ThinkServer TS450 and ThinkStation P310 (SFF/Tower). It will not work in systems that require registered or load-reduced modules. Buyers who need non-ECC memory or a different pin count should look elsewhere.

16GB DDR4 2133 ECC unbuffered

The single deciding specification is the 16GB DDR4 2133 ECC unbuffered configuration in a 288-pin DIMM. This exact combination determines compatibility with the listed Lenovo platforms. Verify your system requires unbuffered ECC before purchase.

Questions about this item

Will the 16GB DDR4 2133 ECC DIMM need replacement if I add more memory later?

The module is unbuffered ECC DDR4 2133, so any future DIMMs must match that speed, voltage and ECC type to avoid mixed-mode errors.

What limit appears first when the 288-Pin DDR4 2133 kit runs at full load in a ThinkServer TS450?

The JEDEC-rated DDR4 2133 (PC4 17000) speed ceiling is reached before thermal or power limits because the stick has no heat spreader.

How much heat and noise does the 16GB KTL-TS421E/16G produce during all-day operation in a ThinkStation P310?

With no heat spreader and standard DDR4 2133 voltage, the module runs cool and silent; system fans dominate any audible noise.
