Capacity and Compatibility

This kit delivers 64GB of DDR4 memory across four 16GB modules. It is validated for the THINKMATE TWX-XS4-14W3 tower server. The ECC unbuffered design targets administrators who need data integrity in a standard UDIMM form factor. Buyers who require registered DIMMs or higher-density single modules cannot use this kit.

Build Integration

The modules install into four 288-pin DDR4 slots and operate at 1.2V. Each stick is a 2Rx8 organization without a heat spreader, leaving clearance for tight CPU coolers. The CL22 latency and PC4-25600 rating match the platform's native memory controller. Systems needing more than four slots or a different pin count are not supported.

Sustained Operation

Samsung, Micron or Hynix ICs are stress-tested under load before shipment to verify stability during extended workloads. The 1.2V operating voltage keeps thermal output modest inside a populated server chassis. ECC correction runs continuously without buffering latency. Workloads that exceed the 64GB total capacity will still hit the operating-system swap limit.

Questions about this item

Does the 3200 MHz DDR4 speed limit sustained throughput under heavy load?

The kit runs at DDR4 3200 (PC4-25600) with CL22 timing; bandwidth is capped by that rated frequency and latency under sustained use.

How much heat and power do the four 16 GB modules generate during all-day operation?

Each module operates at 1.20 V without a heat spreader; total power draw stays low for DDR4 ECC UDIMM, so heat output remains modest in a server chassis.

What must the ThinkMate TWX-XS4-14W3 already have to accept this 288-pin ECC UDIMM kit?

The motherboard needs four free 288-pin DDR4 slots that support unbuffered ECC memory at 1.20 V and 2Rx8 organisation.
