Server memory kit

This 1 TB kit contains sixteen 64 GB DDR5 4800 ECC registered DIMMs built for the ASUS RS720A-E12-RS12 2U dual-processor server. Each module runs at 1.1 V with CL40 latency and a 2Rx4 organisation. The registered design adds a buffer that helps the memory controller maintain signal integrity across all populated slots.

Compatibility scope

The kit is validated for the named ASUS server platform; it will not fit desktop motherboards or laptops that require unbuffered UDIMMs. Systems needing a different capacity, speed grade, or voltage should select a matching kit.

Registered ECC RDIMM

Registered ECC RDIMM architecture is the single specification that determines whether this kit suits your chassis. Only platforms designed for registered error-correcting modules can use it.

Questions about this item

Does the 1 TB kit include all sixteen 64 GB modules or do I need to buy any separately?

The kit contains sixteen 64 GB modules for a total of 1 TB; nothing else is required.

Should I choose the 1 TB 16×64 GB kit or a smaller capacity for the ASUS RS720A-E12-RS12?

Select the 1 TB kit when the server needs maximum registered ECC capacity; choose a smaller kit only if the workload fits in less memory.

What does the DDR5 4800 CL40 rating deliver once installed in the RS720A-E12-RS12?

The modules run at 4800 MT/s with CAS latency 40 at 1.1 V, providing registered ECC throughput matched to the server's memory controller.
