512 GB DDR5 RDIMM Kit

This 512 GB kit contains four 128 GB DDR5 4800 registered DIMMs built for the ASUS Z13PE-D16 server board. It targets IT teams running memory-heavy workloads on that specific platform.

Replaces lower-capacity DDR5 RDIMMs

The jump makes sense when current modules limit virtual-machine density or in-memory database size and the board has four free slots. Buyers who need more than 512 GB total capacity cannot use this kit.

Simple DIMM installation

Modules seat in the standard 288-pin DDR5 slots; the registered design requires the board's memory controller to support registered DIMMs. A mismatched rank population or missing BIOS update can prevent the system from posting.

Questions about this item

Will these 288-pin DDR5 RDIMM modules fit the ASUS Z13PE-D16 server board?

Yes, the kit is validated for the ASUS Z13PE-D16 and uses the standard 288-pin DDR5 RDIMM form factor that matches the board's memory slots.

What is the correct order for populating the four 128 GB modules on the Z13PE-D16?

Follow the motherboard manual's population sequence — typically fill the farthest slot from each CPU first, then the next closest, to maintain quad-channel operation with 4Rx4 modules.

How can I tell when one of the 128 GB ECC RDIMMs needs replacement?

The board's IPMI or OS logs will report correctable or uncorrectable ECC errors tied to a specific DIMM slot; replace the module identified in those logs.
