System-Specific DDR4 Memory Kit

This NEMIX RAM kit delivers 768GB of DDR4 3200 ECC registered memory in six 128GB modules. It is built for the Thinkmate XF4-24S3 workstation using major OEM chips from Samsung, Micron or Hynix. The modules run at 1.20V with CL22 latency and a 4Rx4 organisation. They are validated for mission-critical server workloads requiring maximum capacity and data integrity.

Suited for Thinkmate XF4-24S3 Upgrades

This kit suits administrators expanding a Thinkmate XF4-24S3 to its full memory potential with registered ECC modules. It is not for consumer desktop boards that cannot address 4Rx4 registered DIMMs or that lack the required chipset support. Buyers needing non-ECC unbuffered memory or lower-density modules for other platforms should look elsewhere.

Capacity Decides Fit

The single specification that decides compatibility is the 768GB total capacity arranged as six 128GB 4Rx4 registered DIMMs. The workstation must accept this exact population rule and rank configuration to boot correctly. Verify the system documentation for the maximum supported density per slot and the qualified vendor list before purchasing.

Questions about this item

What does 3200 MT/s mean once the kit is installed in a Thinkmate XF4-24S3?

The modules run at DDR4 3200 (PC4-25600) with CL22 latency, delivering the rated throughput as long as the workstation firmware enables the speed.

What does the registered ECC RDIMM interface cap in practice?

Registered ECC RDIMM adds a register to buffer address and command signals and provides error-correcting code, allowing six 128 GB modules to operate stably at 1.2 V.

What physical slot and clearance does the 288-pin RDIMM need?

Each 128 GB module uses a standard 288-pin DDR4 RDIMM form factor and fits any compatible RDIMM slot without a heat spreader.
