Kit contents and target use

This 64GB kit contains four 16GB DDR5 4800 registered ECC RDIMMs built for the ASUS RS700-E11-RS12U 1U dual-socket server. It suits administrators who need validated, high-density memory for virtualisation or database workloads on that specific platform.

Who should look elsewhere

Builders using non-ASUS servers, desktop motherboards or any system that requires unbuffered DIMMs or lower voltages cannot use these modules. The registered design and 1.10V operation also rule out consumer platforms and older DDR generations.

Deciding specification

Registered ECC with 1Rx8 organisation at DDR5 4800 (PC5-38400) and CL40 latency is the single attribute that determines compatibility; the motherboard must support registered DDR5 at this speed and rank configuration for the kit to function.

Questions about this item

How do I install the 288-pin DDR5 RDIMM modules in the ASUS RS700-E11-RS12U, and what step is often missed?

Power down the server, open the chassis, align each module's notch with the slot key, press firmly until both locking tabs click, then verify all four 16 GB sticks are recognised in the BIOS before closing the case.

What maintenance or replacement will the registered ECC DDR5 kit need over its service life?

No scheduled maintenance is required; if a module fails the lifetime replacement warranty covers it, otherwise the kit runs until a capacity or speed upgrade is desired.

What limit appears first when the 4800 MT/s CL40 1.1 V memory runs sustained workloads?

The DDR5 4800 transfer rate and CL40 latency set the throughput ceiling, so sustained bandwidth tops out at the rated PC5-38400 specification.
