Targeted DDR5 server memory kit

This NEMIX RAM kit delivers 64GB of DDR5 4800 ECC registered memory in two 32GB RDIMM modules. It is built for the ASUS RS720-E11-RS24U 2U dual-socket server and operates at 1.1V with CL40 latency. The 288-pin 1Rx4 modules use major OEM DRAM chips and provide hardware-level error correction for data integrity.

Ideal for compatible ASUS server upgrades

Administrators expanding memory in the specified ASUS 2U platform will find this kit validated for that chassis. It is not suitable for workstations or motherboards that require unbuffered UDIMM modules, for systems that cannot accept registered DIMMs, or for any platform outside the listed compatibility. Builders needing different module densities or voltages should verify their hardware requirements first.

Registered ECC RDIMM form factor

The modules are 288-pin DDR5 RDIMMs with on-board register and ECC functionality, a physical and electrical interface distinct from unbuffered UDIMMs. This registered design is mandatory for the target ASUS server and prevents installation in desktop or consumer boards that lack RDIMM support.

Questions about this item

How much heat does the 1.10 V DDR5 4800 kit produce when running continuously in the RS720-E11-RS24U server?

The modules operate at 1.10 V without a heat spreader, so they rely on the server chassis airflow to stay cool during sustained workloads.

What must the ASUS RS720-E11-RS24U already have installed for this 288-pin RDIMM kit to function?

The motherboard needs an available DDR5 RDIMM slot and a CPU that supports registered ECC memory at 4800 MT/s.

Will the CL40 1Rx4 modules work alongside any existing DDR5 RDIMMs already populating the RS720-E11-RS24U?

Yes, provided the installed DIMMs are also DDR5 registered ECC 1Rx4 parts, the server will train all channels to the common 4800 MT/s speed.
