Capacity & Configuration

This kit delivers 768GB of DDR4 memory across twelve 64GB registered DIMMs. It is built for Thinkmate XF4-24S3 workstations and servers that require large-capacity ECC memory for virtualization, database, or compute workloads.

Who It Suits

IT teams expanding memory in compatible Thinkmate platforms will appreciate the validated 4Rx4 organization and CL22 timing at 3200 MT/s. Systems that cannot accept registered ECC modules or that are limited to lower maximum capacities should consider other options.

Kit Contents

The package includes the full set of twelve 288-pin RDIMMs with no heat spreaders, ready for installation in all populated slots. No additional cables, software licences or cooling accessories are supplied with this memory kit.

Questions about this item

Does the THINKMATE XF4-24S3 workstation need all 12 DIMM slots filled for this 768 GB kit to operate?

The kit contains 12 modules of 64 GB each. If the workstation has exactly 12 slots, the kit fills them all; if it has more slots, the remaining slots can stay empty or be populated with identical modules.

Can I mix these 4Rx4 CL22 1.20 V registered ECC modules with older 2Rx4 or 1Rx4 DDR4 RDIMMs in the same system?

Mixing ranks is not recommended. The motherboard will typically force all channels to the lowest common speed and timing, and registered ECC modules of different rank structures may cause training failures.

After installation, how do I confirm the full 768 GB is recognised and running at DDR4 3200 with ECC active?

Enter the BIOS or UEFI and check the memory information screen — it should show 768 GB total, 3200 MT/s (PC4-25600), CL22, 1.20 V, and ECC enabled.
