Capacity and configuration

This kit provides 768GB of DDR5 ECC registered memory across six 128GB modules. It is built for ThinkMate GPX-XH8-22S4-8GPU servers that require high-density registered DIMMs for multi-socket workloads.

Speed, latency and headroom

Modules run at 4800 MT/s with CL40 latency at 1.1V, delivering PC5-38400 bandwidth. The 4Rx4 organisation maximises rank density per channel, so capacity scales before bandwidth becomes the bottleneck in heavily threaded server tasks.

Platform fit and requirements

The 288-pin RDIMM form factor fits DDR5 registered server motherboards that support 4Rx4 modules and the ThinkMate qualified vendor list. No heat spreader is included, so chassis airflow must meet the platform thermal specification for sustained operation.

Perguntas sobre este artigo

Will the 4Rx4 DDR5 4800 RDIMM modules run alongside existing 2Rx4 DDR5 RDIMMs in my ThinkMate server?

The kit uses 4Rx4 organization; mixing ranks may require specific DIMM-slot population rules defined in the ThinkMate service manual, so verify the supported rank-per-channel limits before combining.

How can I confirm the 1.10 V CL40 ECC RDIMM kit is operating at DDR5 4800 after installation?

Check the BIOS memory-info screen or run a tool such as dmidecode on Linux; both will report the configured speed, voltage, CAS latency and ECC status for each of the six 128 GB modules.

Does the 768 GB kit include a heat spreader or any mounting hardware, or must I purchase them separately?

The specification states no heat spreader is fitted; the package contains only the six 288-pin DDR5 RDIMM modules, so no extra mounting parts are needed or included.
