128GB DDR5 ECC RDIMM Server Module

This NEMIX RAM module provides 128GB of DDR5 4800 memory in a single 288-pin registered DIMM. It operates at 1.1V with CL40 latency and uses a 4Rx4 organisation with on-die ECC for data integrity.

Suited for ASUS Z13PE-D16 server boards only

The part is validated for that specific motherboard and will not function in consumer desktops, laptops or workstations that require unbuffered memory. Buyers needing non-ECC modules or lower capacities should look elsewhere.

Registered ECC with 4Rx4 architecture

The combination of registered signalling, error correction and quad-rank x4 chips determines whether the module is accepted by the target server platform. Verify the motherboard qualification list before purchase.

Questions about this item

Should I choose a single 128GB 4Rx4 module or multiple smaller sticks for the Z13PE-D16?

The module is a single 128GB 4Rx4 stick; the Z13PE-D16 has 16 DIMM slots so you can populate additional slots with identical modules to scale capacity.

What does the DDR5 4800 rating deliver once installed in the ASUS Z13PE-D16 server board?

The module runs at 4800 MT/s with CL40 latency at 1.1V, providing ECC error correction and registered buffering for stable operation under sustained server workloads.

How does the 288-pin DDR5 RDIMM interface limit performance on this platform?

The 288-pin RDIMM form factor locks the module to DDR5 4800 speeds and CL40 timings on the Z13PE-D16; the registered design adds one cycle of address latency but enables the 4Rx4 density.
