NEMIX RAM 512GB (4x128GB) DDR5 4800 CL40 288-Pin ECC RDIMM Dell PowerEdge R760xa Memory Upgrade

512GB DDR5 RDIMM kit for Dell PowerEdge R760xa

This 512GB kit contains four 128GB DDR5 4800 RDIMM modules built for the Dell PowerEdge R760xa. Each module is ECC registered with a 4Rx4 organisation and runs at 1.1V. It targets administrators who need maximum supported capacity in that specific platform.

DDR5 4800 registered ECC limits

The DDR5 4800 standard sets the baseline transfer rate at PC5-38400 with a CAS latency of 40 for registered DIMMs. Registered buffering adds one clock cycle of command delay, which is mandatory for multi-DIMM server configurations. ECC correction handles single-bit errors but cannot repair multi-bit failures.

4Rx4 rank density decides fit

The 4Rx4 rank structure places four logical ranks on each 128GB module, a density the R760xa memory controller must explicitly support. If the platform firmware does not recognise 4Rx4 RDIMMs at this capacity, the system will not post or will report reduced memory. Verify the server qualification list before purchase.
