Dell PowerEdge R760xa 64GB Kit

This 64GB kit contains four 16GB DDR5 4800 ECC RDIMM modules built for the Dell PowerEdge R760xa rack server. Each stick runs at 1.1V with CL40 latency and uses a registered design for signal integrity. The modules are validated for mission-critical enterprise workloads.

DDR5 4800 Registered ECC Limits

The DDR5 4800 standard caps transfer rate at PC5-38400 while the registered buffer adds one cycle of command latency. ECC correction handles single-bit errors but cannot repair multi-bit failures. Four 288-pin slots must be populated identically to maintain quad-channel bandwidth.

1Rx8 Rank Decides Fit

Each module uses a single-rank 1Rx8 organisation that the R760xa memory controller expects per DIMM slot. Mixing dual-rank or x4 parts breaks the trained timing profile and prevents boot. Verify the server requires 1Rx8 registered DIMMs before ordering.

Questions about this item

Should I pick the 64 GB kit or buy single 16 GB modules instead?

The kit supplies four matched 16 GB modules for 64 GB total, guaranteeing identical timings and rank configuration across all slots.

What does the 4800 MT/s rating deliver inside a Dell PowerEdge R760xa?

The server's memory controller runs the modules at 4800 MT/s with CL40 latency, providing the maximum standard DDR5 bandwidth the platform supports.

How does the 288-pin RDIMM interface limit performance in this system?

The registered 288-pin DDR5 RDIMM form factor is keyed for the R760xa's DIMM slots and caps operation at the platform's native 4800 MT/s DDR5 speed.
