System-Specific DDR5 ECC RDIMM

This 32GB registered DDR5 module is built for Micron-compatible server and workstation platforms. It delivers error-correcting code protection and registered signalling for stable operation in multi-module configurations. The single-rank 1Rx4 organisation suits density-optimised memory channels.

DDR5 4800 registered interface limits

The DDR5 4800 standard caps transfer rate at 4800 MT/s and requires a 1.1V supply. Registered buffering adds one clock cycle of latency, so the module runs at CL40 rather than lower-latency unbuffered timings. Motherboards must implement the DDR5 RDIMM protocol; unbuffered consumer boards cannot use this module.

32GB single-module capacity decides fit

One 32GB stick fills a single 288-pin slot, so total system memory grows in 32GB increments. Buyers who need finer granularity or lower per-slot cost should choose smaller modules instead.

Questions about this item

How do I know this 32GB DDR5 4800 CL40 1Rx4 ECC RDIMM is the right capacity and rank for my server?

The module provides 32GB in a single 1Rx4 registered DIMM. Check your motherboard manual for maximum capacity per slot and whether it requires 1Rx4 or 2Rx8 registered memory before ordering.

What does the 4800 MT/s rating deliver in a real workload?

At 4800 MT/s with CL40 latency the module runs at the standard DDR5-4800 data rate. Actual throughput depends on your CPU memory controller, channel population and BIOS settings.

What does the 288-pin RDIMM interface mean for compatibility?

The 288-pin registered DDR5 form factor fits only server and workstation boards that support DDR5 RDIMM memory. It will not fit UDIMM or SODIMM slots.
