512GB DDR5-4800 ECC RDIMM kit

This 512GB kit contains eight 64GB DDR5-4800 registered ECC modules built for the ASUS RS700A-E12-RS12U 1U dual-processor server. Each module runs at 1.1V with CL40 latency and a 2Rx4 organisation on a 288-pin RDIMM form factor. The kit delivers 512GB of registered, error-correcting memory for mission-critical workloads.

Who this suits and who should look elsewhere

IT teams upgrading the named ASUS 1U server to its full 512GB capacity will find a matched, stress-tested kit that installs in minutes. Builders using consumer motherboards, workstations without RDIMM support, or servers that require unbuffered UDIMMs or a different speed grade cannot use this memory.

Deciding specification — registered ECC RDIMM

The modules are registered ECC DDR5 RDIMMs, so the system memory controller must support registered operation and error correction. If the target platform only accepts unbuffered non-ECC DDR5, the modules will not function.

Questions about this item

Should I choose the 512GB kit with eight 64GB modules or a different capacity?

This kit supplies 512GB total using eight 64GB DDR5 RDIMMs, matching the ASUS RS700A-E12-RS12U server's qualified configuration.

What does the 4800 speed rating mean once the modules are installed in the server?

The modules run at DDR5 4800 (PC5-38400) with CL40 latency at 1.10V, delivering the rated throughput the server's memory controller expects.

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

The 288-pin registered DDR5 form factor carries the full PC5-38400 data rate; the server's memory controller and CPU determine the practical ceiling.
