768GB DDR5 ECC RDIMM kit for Thinkmate servers

This 768GB kit contains six 128GB DDR5 4800 registered DIMMs built for Thinkmate HDX-XH24-52S4 high-density servers. It targets IT teams who need maximum memory capacity in a validated configuration. The modules carry ECC and registered buffering for data integrity under sustained workloads.

288-pin registered modules without heat spreaders

Each DIMM uses a 288-pin DDR5 RDIMM form factor and operates at 1.10V with a 4Rx4 organisation. The lack of heat spreaders keeps the profile low for dense server chassis, while registered buffering reduces electrical load on the memory controller. Samsung, Micron or Hynix chips are used depending on supply.

CL40 latency at DDR5 4800 speed

The kit runs at PC5-38400 with a CAS latency of 40 cycles. This timing is the primary figure that determines whether the memory matches the server's qualified vendor list and sustains stability at full population.

Questions about this item

What does the DDR5 4800 PC5-38400 rating mean for real-world throughput?

The kit runs at DDR5 4800 MT/s with a PC5-38400 peak transfer rate.

What physical clearance does the 288-pin RDIMM need inside the Thinkmate HDX-XH24-52S4?

Each 128 GB module is a standard 288-pin DDR5 RDIMM with no heat spreader, so it fits the server's regular DIMM slots.

How do I install the six 128 GB modules in the Thinkmate HDX-XH24-52S4, and what step is often missed?

Power down, open the chassis, populate all six slots following the motherboard's channel order, press each RDIMM until the ejector clips click, then verify 768 GB appears in BIOS.
