512GB DDR5 4800 ECC RDIMM kit

This 512GB kit contains four 128GB DDR5 4800 ECC RDIMM modules built for the ASUS RS700-E11-RS12U 1U dual-socket server. Registered DIMMs with on-die ECC protect data integrity in mission-critical workloads. The modules run at 1.10V with CL40 latency and a 4Rx4 organisation.

Quad-channel 4Rx4 layout

Four 288-pin RDIMMs populate each memory channel to deliver maximum registered capacity per socket. The 4Rx4 rank structure allows the memory controller to interleave across ranks for sustained throughput. No heat spreaders are fitted, so airflow in the 1U chassis must be sufficient for bare DRAM packages.

Verify DIMM slots and BIOS revision

Confirm the RS700-E11-RS12U has at least four free DDR5 RDIMM slots per processor and that the current BIOS supports 128GB 4Rx4 modules at 4800 MT/s. Registered ECC RDIMMs will not work in desktop or unbuffered platforms. Mixed-rank or mixed-voltage configurations are not supported by this kit.

Questions about this item

Will the RDIMMs need any firmware updates or periodic re-seating in the ASUS RS700-E11-RS12U server?

The modules are stress-tested for compatibility with the ASUS RS700-E11-RS12U; no firmware updates or re-seating schedule is required beyond standard server maintenance.

What limits sustained throughput first — the CL40 latency or the 4800 MT/s bus?

The DDR5 4800 bus sets the peak bandwidth ceiling; CL40 timing determines access latency but does not cap throughput.

How much heat and power do the four 128 GB DDR5 4800 RDIMMs draw at 1.1 V under continuous load?

Each module operates at 1.1 V; total kit power scales with all four 128 GB sticks active, and registered buffering adds minimal overhead.
