64GB DDR5 ECC RDIMM kit

This 64GB kit contains two 32GB DDR5 4800MHz modules built to the PC5-38400 standard. Each stick is a 288-pin ECC registered DIMM running at 1.1V with CL40 latency and 1Rx4 organisation. It is validated for the ASUS RS700-E11-RS4U 1U dual-socket server.

Server memory upgrade

The kit targets administrators expanding memory in the RS700-E11-RS4U platform where ECC registered DIMMs are required. It is not suited for workstations or desktops that accept only unbuffered non-ECC modules. Buyers needing higher capacities per slot or lower latency timings should evaluate other qualified parts.

1Rx4 registered DDR5 at 4800MHz

The decisive specification is the 1Rx4 registered DDR5 4800MHz configuration with on-die ECC. The server’s memory controller and qualified-vendor list expect this exact rank structure and speed; a different rank count or an unbuffered module will not post.

Questions about this item

Will the 288-pin RDIMM modules need any firmware updates or thermal-pad replacements over their service life?

The modules are registered ECC DDR5 RDIMMs with no heat spreader; they require no firmware updates and have no user-serviceable thermal components.

What electrical or thermal ceiling appears first when the kit runs at 4800 MT/s continuously in the ASUS RS700-E11-RS4U?

Sustained operation at 1.10 V and CL40 is limited by the server platform's memory-controller thermal design and the registered buffer's current rating.

How much extra heat and fan noise should I expect from the 64 GB kit operating all day at 1.1 V?

Each 32 GB 1Rx4 module draws 1.10 V with no heat spreader, so the chassis fans handle the load; no additional acoustic signature is introduced by the memory itself.
