ASUS Pro WS WRX90E SAGE SE compatible DDR5 kit

This 256GB kit contains two 128GB DDR5 RDIMMs validated for the ASUS Pro WS WRX90E SAGE SE workstation motherboard. It targets professionals who need maximum registered ECC capacity for memory-intensive server workloads. Each module operates at 1.10V with CL40 latency.

DDR5 4800 bandwidth ceiling for registered ECC

The PC5-38400 interface caps peak throughput at 38400 MB/s per module, which is the practical limit for DDR5 4800 registered memory. Registered buffering adds one cycle of command delay, so latency-sensitive tasks see higher effective latency than unbuffered alternatives. The 288-pin form factor fits only DDR5 RDIMM slots.

4Rx4 rank density decides platform support

Each 128GB module uses a 4Rx4 organisation, placing four logical ranks behind a single x4 device width. This density requires a motherboard memory controller and BIOS that explicitly support quad-rank registered DIMMs. Systems limited to dual-rank or single-rank modules cannot use this kit.

Questions sur cet article

Should I choose the 256 GB kit with two 128 GB modules or a different capacity for my ASUS Pro WS WRX90E SAGE SE?

This kit provides 256 GB total using two 128 GB RDIMMs, which matches the board's DDR5 RDIMM requirements and fills two slots for optimal channel population.

What does the DDR5 4800 CL40 rating mean once the modules are installed in the workstation?

The memory will run at 4800 MT/s with a CAS latency of 40 cycles, delivering PC5-38400 bandwidth for server workloads.

How does the 288-pin DDR5 RDIMM interface and registered design affect what the system can use?

The 288-pin DDR5 RDIMM form factor with registered buffering and ECC is required by the WRX90E SAGE SE; the registered design reduces electrical load so the platform can support high-capacity 4Rx4 modules at 1.1 V.
