64GB DDR5 4800 ECC RDIMM

This is a 64GB DDR5 4800MHz ECC registered DIMM built for ASUS 1U dual-socket servers using the RS700-E11-RS12U platform. It operates at 1.1V with CL40 latency and uses a 2Rx4 organisation on 288-pin DDR5 modules. The memory is validated for server motherboards that require registered ECC modules.

Who this suits and who should look elsewhere

This module suits administrators upgrading or populating the specified ASUS 1U server where registered ECC DDR5 is required. It is not for desktop PCs or workstations that accept only unbuffered non-ECC memory. Buyers needing lower capacities, different speeds or unregistered modules should look at other configurations.

The specification that decides fit

The registered ECC RDIMM form factor with 2Rx4 organisation at DDR5 4800MHz is the single specification that determines compatibility. Only systems qualified for this exact registered ECC DDR5 configuration will accept the module.

Questions about this item

What speed does the DDR5 4800 PC5-38400 interface actually run at in this server?

The module is rated at DDR5 4800 MT/s (PC5-38400) and will operate at that speed when the ASUS RS700-E11-RS12U platform supports it.

Does the 288-pin RDIMM fit the ASUS RS700-E11-RS12U 1U chassis without clearance issues?

Yes, the 288-pin DDR5 RDIMM form factor matches the motherboard slots in the RS700-E11-RS12U and the low-profile design clears the 1U enclosure.

What is the correct order for populating the slots when installing a single 64 GB 2Rx4 module?

Follow the ASUS RS700-E11-RS12U manual — typically install in the first slot of each memory controller (e.g., CPU1 DIMM_A1, CPU2 DIMM_G1) to maintain balanced channels.
