NEMIX RAM 64GB (4x16GB) DDR5 4800 ECC RDIMM Dell PowerEdge R760xa memory upgrade

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.
