Dell PowerEdge R760xa server memory kit

This 256GB kit contains two 128GB DDR5 RDIMMs validated for the Dell PowerEdge R760xa rack server. Each module is registered and ECC-enabled for enterprise stability. IT teams use it to expand memory capacity in compatible Dell platforms.

4Rx4 rank configuration determines slot population

The modules use a 4Rx4 organisation running at DDR5 4800 with CL40 latency. This rank structure affects how many DIMMs the server can accept per channel and must match the platform's qualified vendor list. Verify the R760xa memory population rules before ordering.

Registered ECC design sustains data integrity

The 1.10V registered modules include on-die ECC and parity to correct single-bit errors during continuous operation. Stress testing at rated speed confirms stability for virtualisation, database and HPC workloads that run for extended periods.

Questions sur cet article

What does the 4800 MT/s rating mean once the modules are installed in a Dell PowerEdge R760xa?

The server will run the memory at 4800 MT/s, delivering the full PC5-38400 bandwidth for each 128 GB module.

How does the DDR5 RDIMM interface limit performance in this configuration?

The registered DDR5 design adds one cycle of command buffering, but the R760xa memory controller supports the full 4800 MT/s data rate with CL40 latency.

Will these 288-pin modules fit the R760xa memory slots without a heat spreader?

Yes, the 288-pin RDIMM form factor matches the server slots exactly, and the low-profile design without a spreader clears standard CPU heatsinks.
