384GB DDR5 ECC RDIMM kit

This 384GB memory kit contains twelve 32GB DDR5 4800 CL40 registered DIMMs. It is built for the ASUS RS700A-E12-RS4U 1U dual-processor server. ECC and registered buffering protect data integrity in mission-critical workloads.

Capacity and headroom

Twelve 32GB modules populate every slot for a total of 384GB. The 1Rx4 organisation and 1.10V operation keep power draw low while maximising density. CL40 latency at 4800 MT/s delivers stable throughput for virtualisation and database tasks.

288-pin DDR5 RDIMM form factor

Each module uses the 288-pin DDR5 RDIMM interface with ECC and registered signalling. This pin-out and protocol match the ASUS RS700A-E12-RS4U memory controller. Systems requiring unbuffered UDIMMs or a different DDR generation cannot use this kit.

Questions about this item

Will the 12 x 32GB DDR5 4800 CL40 modules run alongside existing DDR5 RDIMMs in my ASUS RS700A-E12-RS4U?

This kit provides 12 modules of 32GB each at DDR5 4800 CL40 1.10V 1Rx4 registered ECC. The ASUS RS700A-E12-RS4U requires identical speed, voltage, rank and ECC type in every populated slot; mixing different DDR5 specifications can prevent the system from posting.

How can I verify the 384GB kit is detected at the correct 4800 MT/s and CL40 timing after installation?

Enter the BIOS on the RS700A-E12-RS4U and confirm total memory shows 384GB, each DIMM reports 32GB 1Rx4, speed reads 4800 MT/s (PC5-38400) and CAS latency shows CL40 at 1.10V.

What is included in the package and are any extra parts needed for installation?

The box contains the 12-module 384GB DDR5 4800 CL40 ECC RDIMM kit (part MR38400-314K12); no heat spreaders, cables, tools or additional components are supplied or required for fitting into the 288-pin RDIMM slots.
