Purpose-Built Server Memory

This 768GB kit delivers twelve 64GB DDR4 3200 registered ECC modules tuned for Thinkmate GPX-XT6-24S3-8NVLINK GPU-optimised servers. The 4Rx4 organisation and CL22 timing at 1.2V match the platform's qualified memory profile for high-density workloads.

Ideal for Maximum-Capacity Thinkmate Builds

Administrators populating every DIMM slot on the target Thinkmate chassis will reach the platform's 768GB ceiling with a single validated kit. Sites needing less total memory, mixed-rank populations, or non-Thinkmate platforms should select a different capacity or compatibility tier.

Twelve-Module Registered ECC Kit

The 288-pin RDIMMs install directly into the server's twelve DDR4 slots without adapters or risers. Registered buffering and on-die ECC reduce electrical load on the memory controller, freeing signal integrity margin for sustained GPU-compute throughput.

Questions about this item

Will this 768GB kit of 12 DDR4 3200 4Rx4 modules install directly into a THINKMATE GPX-XT6-24S3-8NVLINK server?

Yes, the kit is built for that exact model and each 64GB RDIMM fits the 288-pin DDR4 slots.

Can the registered ECC RDIMMs operate alongside older unbuffered DDR4 DIMMs in the same system?

No, registered and unbuffered memory cannot be mixed; all slots must use registered ECC RDIMMs.

How do I confirm the 3200MT/s CL22 speed and ECC function are active after installation?

Check the BIOS memory information screen for DDR4 3200 PC4-25600 CL22 and ECC enabled status.
