ThinkMate Server ECC Kit

This 64GB kit contains four 16GB DDR4 3200 ECC UDIMM modules built for ThinkMate TWX-XS4-14E2 and TWX-XS8-14E2 tower servers. It runs at 1.2V with CL22 latency and uses a 2Rx8 rank layout across 288-pin slots. The unbuffered design suits workstations that need error correction without registered buffers.

Sustained Load Reliability

Modules are stress tested under load before shipping to verify stability during continuous operation. ECC circuitry corrects single-bit errors on the fly, protecting data integrity through long compute runs. The 1.2V operating voltage keeps power draw predictable when all four sticks run at 3200 MT/s.

Straightforward Installation

Each UDIMM seats in a standard 288-pin DDR4 slot; no heat spreader means clearance is rarely an issue in dense server chassis. Populate the four channels in the order your ThinkMate manual specifies to enable quad-channel bandwidth. The only common mistake is mixing these unbuffered sticks with registered DIMMs, which the platform does not support.

Questions about this item

Does the 1.20V DDR4 3200 kit generate much heat when running continuously in a Thinkmate tower server?

The modules run at the standard 1.20 V DDR4 voltage and have no heat spreader, so thermals depend on chassis airflow rather than the DIMMs themselves.

Must the motherboard already support ECC unbuffered UDIMMs and 288-pin DDR4 slots for this 64 GB kit to function?

Yes, the system needs a DDR4 platform that accepts 288-pin ECC unbuffered UDIMMs; the kit is validated for Thinkmate TWX-XS4-14E2 and TWX-XS8-14E2 towers.

Will the CL22 2Rx8 modules operate correctly alongside existing DDR4 3200 ECC UDIMMs already installed?

They will run at the lowest common speed and latency; mixing ranks or CAS timings is functional but may reduce overall memory performance.
