Target system and purpose

This 288-pin DDR5 registered DIMM kit is built for the ASUS RS700-E11-RS12U dual-socket 1U server. It delivers 2TB of ECC memory across sixteen 128GB modules for workloads that require maximum capacity and error correction.

Decisive specification

The kit runs at DDR5 4800 (PC5-38400) with CL40 latency, 1.10V operation and 4Rx4 organisation. These exact parameters must match the server's qualified-vendor list; any deviation in speed, rank or voltage will prevent the system from posting.

Capacity envelope

Sixteen slots are fully populated, so the chassis reaches its 2TB ceiling with no free DIMM sockets for future expansion. The configuration handles large in-memory databases and virtualisation clusters, but further growth demands a platform change.

Questions about this item

What does the 4800MHz speed mean once the modules are installed in the ASUS RS700-E11-RS12U server?

The kit runs at the JEDEC-standard DDR5-4800 data rate with CL40 latency, delivering the rated throughput for each of the 16 modules when the server memory controller is configured for that speed.

What does the PC5-38400 designation tell me about the memory interface?

PC5-38400 is the JEDEC module name for DDR5-4800, confirming the kit uses the standard 288-pin DDR5 RDIMM interface and registered signalling at 1.10 V.

What physical space and slot layout does the 16-module kit need in the RS700-E11-RS12U chassis?

Each module is a standard 288-pin DDR5 RDIMM without a heat spreader, so the 16 sticks occupy 16 DIMM slots in the dual-socket server board; the 1U form factor requires low-profile clearance.
