Capacity and configuration

This kit supplies 64GB of DDR4 memory through eight 8GB registered DIMMs. It is built for the THINKMATE GPX-XS8-14S3-4GPU workstation and suits administrators who need ECC protection for large datasets or virtualised workloads.

Upgrade path

The modules replace lower-capacity DDR4 RDIMMs or fill empty slots to reach the platform's supported density. The jump is worthwhile when error-correcting registered memory is required for stability under sustained compute loads.

Headroom and limits

Eight ranks of 1Rx8 chips at 3200 MT/s and CL22 deliver 25600 MB/s bandwidth per module at 1.2V. The kit handles multi-threaded server tasks and memory-intensive databases, but capacity stops at 64GB and speed is fixed at DDR4 3200.

Questions about this item

Does the 288-pin RDIMM form factor fit the DIMM slots on the Thinkmate GPX-XS8-14S3-4GPU workstation?

Yes, the kit uses 288-pin DDR4 RDIMMs which match the registered DIMM slots on that workstation.

What is the correct way to populate all eight modules on this workstation?

Install one 8 GB module in each of the eight channels following the motherboard's population guide; the common mistake is leaving a channel empty or mixing ranks.

Will the ECC registered modules require any firmware updates or battery replacements over time?

No, the DDR4 ECC RDIMMs have no onboard battery or firmware; they operate at 1.2 V and only need replacement if a module fails.
