384GB DDR5 4800 ECC RDIMM Kit

This is a 384GB DDR5 4800 ECC RDIMM kit built from twelve 32GB modules. It runs at PC5-38400 speed with CL40 latency and 1.10V voltage. The registered design adds a buffer for signal integrity in multi-DIMM configurations. It is intended for server boards that require registered ECC memory.

Suited for ASUS Z13PE-D16 upgrades.

The kit is validated for the ASUS Server Board Z13PE-D16 and similar systems that accept 288-pin DDR5 RDIMMs. Builders using consumer desktop boards or workstations that only support unbuffered UDIMMs cannot use these modules. Buyers who need non-ECC memory or lower capacities should look at other product lines.

1Rx4 registered organisation

Each 32GB module uses a single-rank 1Rx4 layout, allowing the full 12-module population on the Z13PE-D16 without exceeding rank limits per channel. The registered buffer and ECC function work together to maintain data integrity under sustained load. Confirm that your server board supports 1Rx4 registered DDR5 before ordering.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit the memory slots on my ASUS Z13PE-D16 server board?

Yes, the 12 modules are 288-pin DDR5 RDIMMs designed for the Z13PE-D16 board's DDR5 slots.

What is the correct order for populating the 12 slots with these 1Rx4 modules?

Follow the Z13PE-D16 manual's population sequence; install matching 1Rx4 modules in the prescribed channel order for full 384 GB capacity.

Do these ECC RDIMMs require any periodic maintenance or firmware updates?

No routine maintenance is needed; the modules run at 1.10 V with CL40 latency and rely on the server's ECC scrubbing for error correction.
