Capacity 64GB

  • 64 GB capacity extends server memory headroom for virtualisation and large datasets
  • ECC registered design detects and corrects single-bit errors to protect data integrity
  • DDR5 4800 CL40 speed delivers high bandwidth for demanding workloads
  • 1 V operation reduces power draw per module in dense configurations
  • Validated for Dell PowerEdge R760xd2 as direct replacement for part AC239379

Server Memory Upgrade

This 64GB DDR5 4800 CL40 module is built for the PowerEdge R760xd2. The 288-pin registered ECC DIMM operates at 1.1V with a 2Rx4 organisation. It targets administrators who need to expand capacity in a supported Dell server platform.

Replacing Factory Memory

The module replaces Dell part numbers AC239379 and SNPJ52K5C/64G with a JEDEC-compliant alternative. The upgrade is worthwhile when the chassis has free DIMM slots and the workload demands more than the current installed capacity.

Build Integration

Registered ECC memory cannot be mixed with unbuffered or load-reduced DIMMs in the same system. The single 64GB stick adds density without requiring a full kit replacement, leaving remaining slots available for future expansion.

Preguntas sobre este artículo

Will the 288-pin DDR5 RDIMM fit the PowerEdge R760xd2 memory slots?

Yes, the module is a 288-pin DDR5 ECC Registered DIMM built specifically for the PowerEdge R760xd2.

What is the correct way to install this 64 GB DDR5 4800 CL40 module, and what step is often missed?

Power down the server, open the chassis, align the notch on the 288-pin edge connector with the slot key, press firmly until the retention clips lock, then verify in BIOS that the 4800 MT/s speed and CL40 latency are recognised.

When will this 1.1 V ECC Registered RDIMM need replacement or maintenance?

The module has no moving parts and requires no scheduled maintenance; replace it only if memory diagnostics report correctable or uncorrectable ECC errors.
