Server memory upgrade

This 64 GB kit consists of two 32 GB DDR5 RDIMMs built for Thinkmate HDX-XH24-52S4 high-density servers. Each module runs at 4800 MT/s with CL40 latency at 1.1 V and includes on-die ECC with registered buffering. The dual-rank 2Rx8 organisation uses major OEM Samsung, Micron or Hynix chips for enterprise stability.

Replaces slower or smaller DIMMs

Swapping existing DDR5 4800 modules for this kit doubles capacity per slot while keeping the same voltage and timing profile. The jump is worthwhile when workloads exceed current memory headroom or when ECC protection is required for data integrity. Systems already running at the platform maximum speed will not see a frequency gain.

Fits 288-pin DDR5 RDIMM slots

Installation uses the standard registered DIMM form factor without heat spreaders, leaving clearance for dense server chassis airflow. The kit frees additional DIMM slots for future expansion up to the platform limit. Buyers needing unbuffered UDIMMs or non-ECC modules for workstation boards should look elsewhere.

Questions about this item

Does the 288-pin DDR5 RDIMM fit the THINKMATE HDX-XH24-52S4 DIMM slots?

Yes, the 288-pin DDR5 RDIMM form factor matches the server's memory slots exactly.

What is the correct order for seating the two 32 GB modules?

Populate the channels indicated in the server manual, pressing each module until the ejector clips click.

When should the ECC RDIMM kit be replaced?

Replace modules only if memory diagnostics report uncorrectable errors or the system logs persistent corrected errors.
