1.5TB DDR4 ECC RDIMM kit

This 1.5TB memory kit contains twelve 128GB DDR4 3200 registered DIMMs built for Thinkmate GPU-optimised servers. IT teams managing virtualisation hosts or GPU compute clusters use it to reach the high capacities those workloads demand. Each module is stress-tested before shipping to support stable operation in mission-critical environments.

Capacity and headroom

Twelve ranks of 4Rx4 organisation deliver 1.5TB total capacity with ECC protection across all channels. The kit fills every slot on supported Thinkmate GPX-QS4-12E2-4GPU and GPX-QT8-22E2-8GPU platforms, so expansion beyond this point requires a chassis or motherboard change. Workloads that exceed 1.5TB will need a different platform.

Registered 4Rx4 DDR4 3200 CL22 specification

The modules run at DDR4 3200 (PC4-25600) with CL22 latency at 1.20V and present a 288-pin registered interface. Systems that require unbuffered UDIMMs, lower rank counts or different voltages cannot use this kit. Compatibility is limited to the Thinkmate models listed in the specifications.

Questions about this item

Will the 4Rx4 rank layout work with the existing DDR4 3200 modules already in my Thinkmate server?

The 4Rx4 registered ECC design matches the PC4-25600 1.20 V specification of the Thinkmate GPX-QS4-12E2-4GPU and GPX-QT8-22E2-8GPU platforms, so it installs alongside identical DDR4 3200 DIMMs without rank conflicts.

How can I confirm the 12 modules are running at 3200 MT/s with CL22 after installation?

Boot into the server BIOS or use a tool such as dmidecode on Linux to verify each 128 GB DIMM reports DDR4 3200, PC4-25600, CAS 22, 1.20 V and registered ECC status.

Does the kit include anything besides the twelve 128 GB RDIMMs?

The package contains only the 1.5 TB (12 × 128 GB) DDR4 3200 CL22 4Rx4 1.20 V 288-pin ECC registered DIMMs; no heat spreaders, cables or software are supplied.
