Targeted Server Upgrade

This 2TB kit contains sixteen 128GB DDR5 4800 RDIMM modules built for the ASUS RS700A-E12-RS12U dual-processor 1U server. Registered ECC operation at CL40 and 1.10V provides the error correction and signal integrity required for mission-critical workloads. The 4Rx4 organisation maximises density per slot across all sixteen 288-pin sockets.

Compatibility Scope

IT teams maintaining the specified ASUS 1U platform can populate every channel with matched, stress-tested modules in a single purchase. Builders working with other server models, workstations, or desktop mainboards must verify their own qualified-vendor lists because this kit is validated only for the named system.

Deciding Specification

The registered ECC RDIMM form factor with 4Rx4 architecture is the single attribute that determines fit; only platforms designed for registered DDR5 memory with this rank configuration will initialise the kit correctly.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit the memory slots in the ASUS RS700A-E12-RS12U 1U server?

Yes, the kit is built specifically for that model and uses the 288-pin DDR5 RDIMM form factor the board requires.

What is the correct population order for the 16 modules across the dual-processor board?

Follow the ASUS RS700A-E12-RS12U manual — typically fill each channel sequentially per CPU, ensuring identical 4Rx4 modules occupy matching slots on both processors.

When should the 128 GB RDIMMs be replaced or re-qualified in a production environment?

Run a full memory stress test after any firmware update, hardware change, or at the next scheduled maintenance window; ECC will flag correctable errors before a module needs swapping.
