Twelve green DDR5 RDIMM modules in a row

NEMIX RAM

NEMIX RAM RS700-E11-RS4U 768GB 12x64GB DDR5 4800 CL40 ECC RDIMM memory upgrade

SKU CH-DD4Q-RT83R MPN RS700-E11-RS4U

A 768GB registered DDR5 kit of twelve 64GB modules at 4800 speed with ECC and CL40 latency for the ASUS RS700-E11-RS4U server

  • Capacity768GB (12 x 64GB)
  • SpeedDDR5 4800 (PC5 38400)
  • ECCYes
  • Buffered/RegisteredRegistered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.10V
  • 768GB total capacity across 12 modules of 64GB each
  • DDR5 4800 speed rated at PC5-38400 for server workloads
  • ECC registered RDIMM design protects data integrity in critical systems
  • Low 1.10V operation reduces power draw in dense configurations
  • Validated for ASUS RS700-E11-RS4U 1U dual-socket server platform

Capacity and Form Factor

This 768 GB kit contains twelve 64 GB DDR5 RDIMM modules built for the ASUS RS700-E11-RS4U dual-socket 1U server. Each module uses a 288-pin layout and runs at 4800 MT/s with CL40 latency at 1.10 V. The registered design with ECC support targets enterprise workloads that demand data integrity.

Suitable Builds and Limitations

The kit is intended for IT teams upgrading the named ASUS 1U platform to its maximum supported memory. Buyers who need a different capacity, a non-registered DIMM type, or compatibility with another server model should look elsewhere. The fixed twelve-module count also means partial upgrades are not possible with this package.

Deciding Specification

The registered ECC RDIMM format combined with the exact 12 x 64 GB configuration is the single factor that determines fit. Only systems qualified for this precise module arrangement will accept the kit without configuration errors.

Questions about this item

Does this 12-module kit require an ASUS RS700-E11-RS4U server with both CPU sockets populated to use all 768GB?

The kit is built for the ASUS RS700-E11-RS4U dual-socket platform; each processor controls its own memory channels, so all 12 DIMM slots — and the full 768GB — are only available when both sockets have a compatible CPU installed.

If I keep existing DDR5 4800 CL40 RDIMMs in the server, will they run together with these 2Rx4 modules at the rated speed?

Mixing ranks or CAS latencies forces the memory controller to default to the slowest common timing; for guaranteed DDR5 4800 operation the new 2Rx4 CL40 modules should populate every slot in matched sets per CPU.

After installation, how can I confirm the system sees all 768GB at DDR5 4800 with ECC active?

Enter the BIOS or UEFI and check the memory information screen — it should report 768GB total, 4800 MT/s speed, CL40 latency, 1.10 V voltage and ECC enabled for each of the 12 installed DIMMs.
