System-Specific DDR4 ECC Kit for ThinkMate Tower

This 128 GB kit contains four 32 GB DDR4 3200 UDIMM modules built for the ThinkMate TWX-XS4-14W3 tower server. ECC unbuffered operation protects data integrity in workloads that cannot tolerate silent corruption. The kit targets administrators who need validated, capacity-matched memory for that specific platform.

Tool-Less DIMM Installation

Modules slot into the server's 288-pin DDR4 sockets without tools; power down, open the chassis, and press each stick until the retention clips engage. The most common issue is mixing this kit with existing modules of different rank or speed, which can prevent the system from posting or force a lower common speed across all channels.

DDR4 3200 Interface Limits Maximum Bandwidth

The PC4-25600 interface caps theoretical throughput at the DDR4 3200 rate, so applications that scale with memory bandwidth will hit that ceiling. Latency is fixed at CL22 and voltage at 1.20 V, leaving no headroom for manual timing tightening or voltage scaling on this platform.

Questions about this item

How can I verify the 3200 MHz CL22 kit is running at full speed after installation?

Enter the BIOS on the THINKMATE TWX-XS4-14W3 and confirm the memory frequency reads 3200 MT/s with CAS latency 22; the ECC status should also show enabled.

What comes in the box and do I need extra parts?

The package contains four 32 GB 288-pin DDR4 ECC UDIMM modules totalling 128 GB; no heat spreaders, cables or tools are included and none are required.

Should I choose this 128 GB 4 x 32 GB kit or a different capacity for the TWX-XS4-14W3?

Select this 4 x 32 GB kit when the server has four available DIMM slots and you want the maximum 128 GB capacity at 1.20 V; smaller kits leave slots free for later expansion.
