512GB DDR5 4800 ECC RDIMM kit

This 512GB kit contains eight 64GB DDR5 4800 ECC RDIMM modules built for ASUS RS700-E11-RS12U 1U dual-socket servers. Registered buffering and on-die ECC protect data integrity under sustained workloads. The modules run at 1.10V with CL40 latency and a 2Rx4 rank structure. No heat spreaders are fitted, matching the density requirements of 1U chassis.

Who this suits and who it does not

IT teams upgrading memory in the named ASUS 1U server to the full 512GB capacity will find a validated, matched set. Builders using consumer motherboards, workstations without RDIMM support, or servers that require UDIMM or LRDIMM modules cannot use this kit. Buyers needing lower capacities, different speeds, or non-ECC memory should select another product.

The deciding specification

The kit is qualified specifically for the ASUS RS700-E11-RS12U server model; the part number MR38400-924K8 appears on the vendor compatibility list for that system. If your server is a different model, even from the same vendor, the memory may not be supported. Always verify the exact system part number before ordering.

Questions about this item

How can I verify the 512GB kit is running at 4800 MT/s after installation?

Check the memory speed reported in the server BIOS or UEFI; it should show DDR5 4800 (PC5-38400) with CL40 timings and 1.10 V.

What comes in the box and is anything else required to use the kit?

The package contains eight 64 GB 288-pin DDR5 RDIMM modules; no extra parts are needed for installation in the compatible ASUS 1U dual-socket server.

Which capacity version should I choose for the RS700-E11-RS12U?

This kit provides the full 512 GB (8 × 64 GB) supported by the RS700-E11-RS12U; select it when you need the maximum registered ECC capacity for that server.
