Compatible server memory kit

This kit supplies 256 GB of DDR5 ECC registered memory in two 128 GB modules for the ASUS RS720A-E12-RS24U dual-processor server. It runs at 4800 MT/s with CL40 latency at 1.1 V. The 288-pin RDIMM form factor matches the platform's memory slots.

Suited for capacity-bound workloads.

IT teams expanding memory for virtualization, databases or large datasets in the named 2U server will benefit from the 4Rx4 registered design. Builders using consumer motherboards, workstations without registered DIMM support or systems requiring unbuffered ECC should select different memory.

Registered ECC RDIMM requirement

The modules are DDR5 4800 registered ECC RDIMMs with a 4Rx4 organisation. Only platforms that explicitly support registered ECC DDR5 RDIMMs can use this kit; unbuffered or non-ECC boards will not accept it.

Questions about this item

Should I choose the 256GB kit with two 128GB modules or a different capacity for my ASUS RS720A-E12-RS24U server?

This kit provides 256GB total using two 128GB DDR5 4800MHz ECC RDIMM modules, matching the server model RS720A-E12-RS24U specification.

What does the 4800MHz speed mean for actual performance inside the RS720A-E12-RS24U?

The modules run at DDR5 4800 (PC5-38400) with CL40 latency and 1.1V, delivering the rated throughput the server's memory controller supports.

Does the 288-pin DDR5 RDIMM interface limit how much bandwidth the system can use?

The 288-pin DDR5 RDIMM form factor carries the 4800MHz signal; bandwidth is capped by the CPU's memory controller, not the module connector.
