16-module DDR5-4800 CL40 ECC registered RDIMM kit delivering 1 TB for ASUS Z13PE-D16 servers
This 1TB kit contains sixteen 64GB DDR5 registered DIMMs rated at 4800 MT/s with CL40 latency. ECC and registered buffering provide the data integrity and signal stability required by multi-socket server platforms. The modules are validated for the ASUS Z13PE-D16 board and operate at the standard 1.1V DDR5 voltage.
The modules have no heat spreader, relying on chassis airflow for cooling during sustained workloads. Registered buffering and the low 1.1V operating voltage help keep per-module power draw modest even when all sixteen slots are populated. Silent operation is inherent because there are no moving parts on the DIMMs themselves.
Each 288-pin RDIMM occupies one DDR5 slot, so the host board must provide sixteen compatible slots and a BIOS that supports 1TB total capacity. The 2Rx4 organisation allows high density without increasing electrical load per channel. Builders needing fewer than sixteen modules or non-ECC memory should select a different kit.

Power down the server, open the chassis, align each 288-pin module with the slot key, press firmly until both latches click, then verify all 16 modules appear in the BIOS memory map — the step most often missed is confirming every module registers in BIOS before closing the case.
The modules have no heat spreaders and no moving parts, so no routine maintenance is required; replacement is only needed if a module fails, which is covered by the lifetime replacement warranty.
The CL40 latency at 4800 MT/s sets the throughput ceiling; under continuous load the memory controller reaches its bandwidth limit before thermal throttling occurs on these bare modules.
