Compatible Server Memory Upgrade

This 128 GB kit contains eight 16 GB DDR5 4800 modules built for the ASUS RS720-E11-RS12U 2U dual-socket server. It targets administrators who need to expand memory capacity in that specific platform.

Registered ECC DDR5 4800 CL40 Specification

The modules run at 1.10 V with a CL40 latency and a 1Rx8 organisation. Registered buffering and on-die ECC provide the error correction and signal integrity required by the qualified server motherboard.

Eight-Module Kit Simplifies Deployment

Supplying all eight DIMMs in one package lets you populate the appropriate channels in a single maintenance window. No extra cables, brackets or software licences are included with the memory kit.

Questions about this item

What does the 4800 MT/s speed mean once the modules are installed in the ASUS RS720-E11-RS12U server?

The kit runs at DDR5 4800 (PC5-38400) with CL40 latency at 1.10 V, delivering 128 GB of registered ECC capacity across eight 16 GB 1Rx8 modules for the qualified platform.

How does the DDR5 RDIMM interface and ECC registration affect usable bandwidth and error handling?

Registered DDR5 with on-die ECC corrects single-bit errors and detects multi-bit errors while the register buffers command signals, letting all eight modules operate at the rated 4800 MT/s without signal degradation.

What physical slot and clearance requirements apply to these 288-pin modules in the target 2U chassis?

Each module is a standard 288-pin DDR5 RDIMM without a heat spreader, so it fits the server's DIMM slots directly; the low-profile height suits the 2U form factor.
