ASUS RS720A-E12 Server Memory Kit

This 128GB DDR5 kit contains four 32GB registered DIMMs built for the ASUS RS720A-E12-RS24U dual-processor server. Modules run at 4800MT/s with CL40 latency at 1.10V and include on-die ECC for data integrity. The 1Rx4 organisation and 288-pin RDIMM form factor match the platform's memory controller requirements.

Ideal for IT teams scaling ASUS RS720A-E12 capacity

Administrators expanding memory in the named ASUS 2U server will find the exact speed, voltage and registered buffer the firmware expects. Buyers needing unbuffered UDIMMs, non-ECC modules, lower CAS latency or a different pin count should select another product.

4800MT/s DDR5 288-pin RDIMM with ECC

The registered DDR5 interface at 4800MT/s is the single specification that determines compatibility with the ASUS RS720A-E12-RS24U memory slots. Modules that differ in speed, buffering or error-correction type will not function in this system.

Questions about this item

How do I install the 288-pin DDR5 RDIMM modules in the ASUS RS720A-E12-RS24U server, and what step is often missed?

Power down, open the chassis, align each module's notch with the slot key, press firmly until the ejector tabs click shut, then verify all four 32 GB sticks are recognised in the BIOS before closing the case.

What maintenance or replacement will this 128 GB DDR5 4800 ECC registered kit need over its service life?

No routine maintenance is required; the modules have no heat spreaders or moving parts, so replacement only occurs if a stick fails ECC scrubbing or the server is upgraded beyond 128 GB total capacity.

What limit appears first when the 1Rx4 DDR5 4800 CL40 memory runs sustained workloads on this platform?

The CL40 latency at 4800 MT/s sets the bandwidth ceiling; sustained throughput cannot exceed the PC5-38400 rating regardless of how long the load runs.
