System-specific DDR5 kit for Dell PowerEdge R760xa

This 128 GB kit contains eight 16 GB DDR5 4800 CL40 registered ECC RDIMMs built for the Dell PowerEdge R760xa rack server. Each module runs at 1.10 V with a 1Rx8 organisation and 288-pin form factor. The kit is validated for Dell enterprise platforms and ships ready for installation.

Eight matched modules simplify large-capacity

Supplying the full 128 GB in a single kit removes the need to source individual sticks and guarantees matched timings across all channels. Registered ECC operation adds error correction and signal buffering required by the server platform. The 1.10 V DDR5 voltage aligns with the system memory subsystem.

Registered ECC RDIMM requirement dictates

Only systems that accept DDR5 4800 registered ECC RDIMMs with a 1Rx8 layout can use this memory. Desktop boards, consumer laptops or platforms limited to unbuffered non-ECC modules will not support the kit. Verify the server memory qualification list before purchase.

Questions about this item

Will the eight 16 GB modules need any firmware updates or re-seating over time?

Registered ECC DDR5 modules do not require firmware updates; reseating is only needed if the server is moved or the DIMM slots are disturbed.

What limit appears first when the kit runs at 4800 MT/s continuously?

The CL40 latency and 1.10 V operating point are the primary constraints; thermal throttling is not triggered because the modules have no heat spreader and rely on chassis airflow.

How much heat and noise does the 128 GB kit add when the R760xa runs all day?

Each 1.1 V 1Rx8 module draws minimal power and has no spreader, so added heat is low and noise is unchanged — only the server fans respond to total system load.
