System-Specific DDR5 Server Memory Kit

This NEMIX RAM kit delivers 192 GB of DDR5 ECC registered memory in six 32 GB modules. It is built for the ASUS RS700A-E12-RS4U 1U dual-processor server and runs at 4800 MT/s with CL40 latency. The modules operate at 1.10 V and use a 288-pin RDIMM form factor with 1Rx4 organisation.

Compatibility and Use-Case Fit

This kit suits administrators upgrading or populating the named ASUS 1U server where registered ECC DDR5 is required. It will not suit builds that need unbuffered UDIMM modules, non-ECC memory, or a different DDR generation. Buyers with other server platforms should verify their qualified-vendor list before purchasing.

Decisive Specification

The registered ECC RDIMM design with 1Rx4 rank organisation is the single attribute that determines whether this kit works in the target ASUS 1U server. Only systems qualified for registered DDR5 ECC memory at 4800 MT/s can accept these modules.

Questions about this item

Does the ASUS RS700A-E12-RS4U server need all 12 DDR5 slots filled for this 192GB kit to operate?

The kit provides six 32GB modules. The RS700A-E12-RS4U supports 12 slots across two processors; populate the six slots for the first CPU first, then add the second CPU kit if required.

Can I keep my existing DDR5 4800 ECC RDIMM modules and add this 1Rx4 kit without changing BIOS settings?

Yes, if the installed modules are also DDR5 4800 ECC RDIMM. Match speed, voltage (1.10V) and registered type; the system will train at the common 4800 MT/s CL40 settings.

After installing the six 32GB modules, how do I confirm the server sees the full 192GB at 4800 MT/s with ECC active?

Enter BIOS or UEFI on boot; the memory information screen should show 192GB total, 4800 MT/s operating speed, and ECC status as enabled or active.
