Server-grade capacity for Thinkmate GPU servers

This 512GB kit combines four 128GB DDR4 3200 ECC RDIMM modules built for Thinkmate GPX-XS12-24S3-8GPU systems. Registered 4Rx4 organisation and 1.2V operation suit memory-dense GPU-optimised servers running virtualisation or HPC workloads. Buyers who need non-ECC UDIMMs or desktop DIMM form factors cannot use this kit.

Thermals and power in typical server chassis

Modules run at the standard DDR4 1.20V without heat spreaders, relying on chassis airflow for cooling. Registered buffering adds negligible latency while keeping signal integrity across all 288 pins at 3200 MT/s. No active cooling or extra power headers are required beyond the motherboard DIMM slots.

Compatibility assurance and validation

Each module is stress-tested under load before shipping to confirm stability in the qualified Thinkmate platform. The kit arrives as a matched set of four 128GB sticks labelled MR25600-744K4 for straightforward installation. No software utilities, drivers or firmware updates are bundled with the memory.

Questions about this item

How do I install these 288-pin DDR4 RDIMM modules in the ThinkMate GPX-XS12-24S3-8GPU server, and which step is most often missed?

Power down the server, open the chassis, align each module's notch with the slot key, press firmly until both latches click, then verify all four 128GB modules are recognised in BIOS before closing the case.

What maintenance or replacement will this 512GB ECC registered kit need over its service life?

The modules have no moving parts and no heat spreaders; they require no scheduled maintenance, and ECC error correction handles correctable errors automatically.

What limit appears first when this 4Rx4 CL22 memory runs sustained workloads at 3200 MT/s?

The CAS latency of 22 cycles at 1.20V sets the timing ceiling; sustained throughput is bound by the DDR4 3200 PC4-25600 transfer rate.
