System-Specific ECC RDIMM Kit

This 64 GB kit contains four 16 GB DDR5 4800 registered DIMMs built for the ASUS Pro WS WRX90E SAGE SE workstation. It targets IT professionals and workstation builders who need validated ECC memory for mission-critical workloads.

Registered DDR5 4800 with CL40 Latency

The modules run at DDR5 4800 (PC5-38400) with a CAS latency of CL40 at 1.1 V. Each stick is a single-rank 1Rx8 288-pin RDIMM using major OEM chips. ECC and registered buffering are mandatory for the target platform; non-ECC or unbuffered DIMMs will not function.

Straightforward DIMM Installation

Installation follows the motherboard manual: populate the indicated slots in the correct order, seat each module until the latches click, then verify capacity in BIOS. The most common issues are mixing registered with unbuffered DIMMs or skipping the required slot sequence, both of which prevent the system from posting.

Questions about this item

What does the 4800 MT/s speed deliver in the ASUS Pro WS WRX90E SAGE SE?

The kit runs at DDR5 4800 (PC5-38400) with CL40 latency at 1.10 V, providing registered ECC bandwidth tuned for that workstation platform.

How does the registered ECC RDIMM interface affect usable capacity and stability?

Each 1Rx8 module is registered and ECC enabled, so the memory controller sees 64 GB of error-correcting capacity with buffered signalling for multi-DIMM stability.

Will the 288-pin modules fit the motherboard slots without a heat spreader?

Yes, the bare 288-pin DDR5 RDIMMs install directly into the board's RDIMM slots; no spreader clearance issues exist.
