Capacity and configuration

This kit provides 128GB of DDR5 memory using two 64GB registered DIMMs. It runs at 4800 MT/s with a CAS latency of 40 at 1.10V. The modules are ECC registered with a 2Rx4 organisation and fit 288-pin slots.

Who this suits and who it does not

It is built for the ASUS RS700A-E12-RS4U dual-processor 1U server where the motherboard requires registered ECC DDR5. Builders using desktop boards, workstations that need unbuffered memory, or systems limited to lower capacities should look elsewhere.

Deciding specification

The registered ECC DDR5 interface with 2Rx4 organisation is the single factor that determines compatibility; only platforms that explicitly support registered DDR5 ECC RDIMMs can use this kit.

Questions about this item

Does the 288-pin DDR5 RDIMM form factor fit the ASUS RS700A-E12-RS4U server motherboard?

Yes, the 288-pin DDR5 RDIMM modules are built to match the DIMM slots on the ASUS RS700A-E12-RS4U 1U dual-processor server.

What is the correct way to install the two 64 GB modules for dual-channel operation?

Populate one module per CPU socket following the motherboard manual slot order; the common mistake is placing both modules on the same socket.

When should the registered ECC modules be replaced if correctable errors start appearing?

Replace the modules when the system logs show a rising correctable-error count or when the memory diagnostic reports persistent single-bit failures.
