2TB DDR5 4800 ECC RDIMM kit

This 2 TB kit contains sixteen 128 GB DDR5 4800 registered DIMMs built for the ASUS RS720A-E12-RS24U dual-processor server. ECC and register buffering protect data integrity in mission-critical workloads. The modules run at 1.1 V with CL40 latency. They are intended for IT teams upgrading that specific 2U platform.

DDR5 4800 registered interface limits

DDR5 4800 (PC5-38400) sets the maximum transfer rate for this kit. The registered design adds a clock cycle, so latency is higher than unbuffered memory. Four-rank 4Rx4 organisation increases density but can restrict the number of modules per channel. Buyers needing higher frequencies or lower latency must choose a different platform.

No heat spreader, 288-pin RDIMM form factor

Modules ship without heat spreaders, relying on server chassis airflow for cooling. The 288-pin DDR5 RDIMM keying prevents insertion into consumer UDIMM slots. Sixteen modules fill every slot in the target 2U system, leaving no room for further expansion. Builders who need spare slots for future growth should verify the motherboard layout first.

Questions about this item

Should I choose the 16x128GB kit or a smaller capacity?

This kit provides 2TB total using sixteen 128GB modules; no smaller capacity options are offered for this part number.

What does the 4800MHz speed mean for my ASUS RS720A-E12-RS24U server?

The modules run at DDR5 4800 (PC5-38400) with CL40 latency, delivering the rated throughput when installed in compatible slots.

How does the 288-pin DDR5 RDIMM interface limit performance?

The 288-pin DDR5 RDIMM form factor supports registered ECC operation at 1.10V, capping speed to the JEDEC 4800MT/s standard for this platform.
