Dell PowerEdge R760xa 256GB kit

This 256GB kit contains four 64GB DDR5 registered DIMMs built for the Dell PowerEdge R760xa server. The modules provide ECC error correction and registered buffering for stable operation in enterprise workloads. IT teams can expand memory capacity without mixing module densities. The kit is validated for the target platform by the supplier.

1.10V operation at 4800 MT/s

Each module runs at 1.10V with a CAS latency of 40 and a data rate of 4800 MT/s. The low-voltage DDR5 design reduces power draw per gigabyte compared with earlier generations. Registered signalling lightens the electrical load on the memory controller during sustained traffic. No heat spreaders are fitted, so airflow through the chassis handles cooling.

Major OEM Samsung Micron Hynix chips

The DIMMs use DRAM from major OEM suppliers Samsung, Micron or Hynix depending on production allocation. All modules undergo stress testing under load before shipment to verify stability. The supplier provides a lifetime replacement warranty and US-based technical support for compatibility questions. No additional software or accessories are included in the package.

Questions about this item

How do I install the four 64 GB DDR5 4800 RDIMMs in a PowerEdge R760xa, and what step is often missed?

Power down the server, open the chassis, and seat each 288‑pin module fully until the ejector clips lock; the step often missed is confirming the memory configuration in the BIOS so all 256 GB are recognised at 4800 MT/s.

What maintenance or replacement will the ECC RDIMM kit need over its service life?

The modules have no moving parts or heat spreaders, so no routine maintenance is required; replacement is only needed if a module fails, which the lifetime warranty covers.

What limit appears first when the 256 GB kit runs sustained workloads at 1.10 V?

The CL40 latency at 4800 MT/s sets the throughput ceiling; sustained heavy loads will hit that timing boundary before voltage or thermal limits become a factor.
