Targeted Server Upgrade

This NEMIX RAM kit provides 128GB of DDR5 ECC RDIMM memory across four 32GB modules. It is built for IT professionals managing the ASUS RS700A-E12-RS4U 1U dual-processor server who need registered, error-correcting capacity for virtualization or database workloads.

Build Integration

The 288-pin RDIMMs operate at 1.1V with a CL40 latency rating and 1Rx4 organization. They slot directly into the compatible ASUS server motherboard, using registered buffering to maintain signal integrity across all populated channels without requiring additional cooling hardware.

Ready-to-Deploy Kit

The package delivers a matched set of four modules tested under load for stability in the target platform. This eliminates the guesswork of mixing individual sticks and ensures the full 128GB capacity is recognized immediately upon installation.

Questions about this item

How does the 1.10V voltage affect heat output when the kit runs continuously at 4800 MT/s?

At 1.10 V the four 32 GB modules draw less power than higher-voltage DDR5, so sustained server workloads produce less heat inside a 1U chassis.

Does the CL40 latency become a bottleneck during long compute jobs on the RS700A-E12-RS4U?

CL40 is the rated CAS latency for this 4800 MT/s kit; the registered buffer and ECC add stability for continuous operation rather than raw speed.

Will the 288-pin RDIMM kit work without a compatible ASUS 1U dual-processor motherboard?

The kit is validated for the ASUS RS700A-E12-RS4U server; other platforms may not support the registered ECC 1Rx4 configuration.
