64GB DDR5 ECC RDIMM for ASUS WRX90E SAGE SE

This 64GB DDR5 4800 module is built for the ASUS Pro WS WRX90E SAGE SE workstation motherboard. It delivers registered ECC memory for professional workloads that require data integrity. The single 288-pin RDIMM installs directly into compatible slots.

Registered DDR5 4800 tops out at 4800 MT/s

The DDR5 4800 standard sets the practical ceiling at 4800 MT/s and CL40 timing for this registered ECC class. Bandwidth reaches PC5-38400 while the registered buffer adds a cycle for signal stability. Higher speeds need different modules and platform support.

2Rx4 organisation decides dense capacity per slot

The 2Rx4 rank layout packs 64GB into one 288-pin RDIMM at 1.10V. This organisation maximises capacity per channel on the WRX90E platform. Systems needing more ranks per channel or different density must choose another part number.

Questions about this item

Should I pick the single 64GB module or combine multiple sticks?

The module is sold as a single 64GB stick. Add more identical units to reach the capacity your ASUS Pro WS WRX90E SAGE SE board supports.

What does the 4800 speed rating deliver in daily workloads?

DDR5 4800 runs at 4800 MT/s with CL40 latency, giving high bandwidth for multi-threaded server tasks while ECC corrects single-bit errors.

Does the 288-pin RDIMM interface limit how fast the memory can run?

The 288-pin DDR5 RDIMM form factor carries the 4800 MT/s signal; the registered buffer and ECC add stability but do not reduce the rated speed.
