Capacity and purpose

This kit provides 768GB of DDR5 memory across six 128GB modules, built for the ASUS Z13PE-D16 server board. Registered ECC operation and a CL40 latency at 4800MHz target stability in multi-socket workloads. It suits administrators expanding memory capacity in compatible ASUS server platforms.

Registered ECC design

Each module uses a 288-pin DDR5 RDIMM form factor with a 4Rx4 organisation and runs at 1.1V. The registered buffer reduces electrical load on the memory controller, while on-die ECC corrects single-bit errors without host intervention. No heat spreader is fitted, so airflow in the chassis must handle module cooling directly.

Module composition and validation

Samsung, Micron or Hynix DRAM components are selected per build and stress-tested under load before shipping. The kit arrives as a matched set of six modules under part number MR38400-744K6, intended for simultaneous population of all channels. Lifetime replacement coverage backs the validated configuration.

Questions about this item

What speed does the DDR5 4800 interface deliver in practice?

The kit runs at DDR5 4800 (PC5-38400) with CL40 latency and 1.1 V operation.

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

Each 128 GB module is a 288-pin DDR5 RDIMM without a heat spreader, so it fits standard server DIMM slots with normal height clearance.

How is the 6-module kit installed, and which step is often missed?

Populate all six slots per the ASUS Z13PE-D16 manual, ensuring each registered DIMM clicks fully into the 288-pin socket; the common mistake is leaving a module slightly unseated.
