64 GB DDR5 ECC RDIMM for ASUS Z13PE-D16

This registered DDR5 module provides 64 GB of error-correcting memory at 4800 MT/s with CL40 latency. It operates at 1.1 V using a 2Rx4 organisation on a 288-pin form factor. The part is validated for the ASUS Z13PE-D16 server board and built with major OEM DRAM chips.

Upgrade from lower-capacity or non-ECC DDR5 DIMMs

Replacing smaller unbuffered modules with this 64 GB registered stick adds density and data integrity for virtualisation or database workloads. The jump is worthwhile when the platform requires registered ECC memory and the application benefits from larger per-slot capacity. Systems limited to unbuffered memory cannot use this module.

Sustained load behaviour with registered ECC design

The registered buffer reduces electrical load on the memory controller during continuous operation. ECC circuitry corrects single-bit errors on the fly, maintaining data accuracy under prolonged stress. Modules are stress-tested under load before shipping to verify stability in mission-critical environments.

Questions about this item

Will this 288-pin DDR5 RDIMM fit a standard server DIMM slot?

Yes, the module uses the 288-pin DDR5 RDIMM form factor that matches standard registered server DIMM sockets.

What is the correct way to seat this registered ECC module so the register engages?

Align the notch with the slot key, press straight down until both retention clips click, ensuring the register contacts fully seat.

When should the 64GB 2Rx4 DDR5 module be replaced in a 24/7 server?

Replace it if ECC correctable error counts rise steadily or if memory diagnostics report uncorrectable failures on this rank.
