256GB DDR5 4800 ECC RDIMM kit

This 256GB memory kit contains eight 32GB DDR5 4800 registered DIMMs with ECC and a CAS latency of CL40. The modules operate at 1.1V and use a 288-pin form factor with 1Rx4 organisation. They are built for the ASUS RS700A-E12-RS4U dual-processor 1U server.

Who this suits and who it does not

The kit suits administrators upgrading or populating the named ASUS 1U server with validated ECC registered memory. It does not suit builds that need unbuffered DIMMs, non-ECC modules, a different pin count, or a lower total capacity than 256GB.

The specification that decides fit

The decisive specification is the DDR5 4800 registered ECC RDIMM type matched to the ASUS RS700A-E12-RS4U qualified-vendor list. Only modules with this exact registration, speed, voltage and pin-out will post reliably in that platform.

Questions about this item

Will the 1.1V DDR5 modules increase heat or power draw when the server runs continuously?

Each module operates at 1.10V, the standard voltage for DDR5, so power draw per DIMM stays at the JEDEC baseline even under sustained load.

Does the ASUS RS700A-E12-RS4U motherboard need a specific BIOS version or CPU generation to recognise the 8×32GB kit?

The kit is validated for the ASUS RS700A-E12-RS4U platform; install all eight 288-pin RDIMMs in the correct slots and the system will detect the full 256GB at 4800 MT/s.

Can I keep existing 1Rx4 DDR5 RDIMMs in the other channels while adding this 256GB kit?

Yes, provided the remaining modules are also DDR5 1Rx4 ECC registered DIMMs, the memory controller will train all channels to the common 4800 MT/s CL40 speed.
