NEMIX RAM 256GB (16x16GB) DDR5 4800 CL40 ECC RDIMM Dell R760xa memory upgrade

256 GB DDR5 ECC RDIMM kit for Dell R760xa

This 256 GB kit contains sixteen 16 GB DDR5 4800 CL40 registered DIMMs built for the Dell PowerEdge R760xa. ECC and registered buffering provide the data integrity required in production server workloads. The modules run at 1.1 V and use a 288-pin DDR5 form factor.

Fills all sixteen slots in a single upgrade

Populating every DIMM slot with matched 1Rx8 modules removes the need to mix capacities or ranks later. The kit is validated for the R760xa memory subsystem so the server can boot at the rated 4800 MT/s speed without manual timing changes. No heat spreaders are fitted, leaving clearance for the system’s own airflow path.

Low-voltage DDR5 reduces power draw at load

Operating at 1.1 V keeps per-module power lower than previous DDR generations during sustained compute tasks. Registered buffering adds minimal latency while stabilising the signal across all sixteen ranks. The absence of spreaders means thermal performance depends on the chassis fan profile, which the R760xa manages automatically.
