NEMIX RAM 512GB (8x64GB) DDR5 4800 CL40 ECC RDIMM Dell PowerEdge XE8640 memory upgrade

512 GB DDR5 RDIMM kit for Dell PowerEdge XE8640

This 512 GB kit contains eight 64 GB DDR5 4800 registered ECC modules built for the Dell PowerEdge XE8640 rack server. It targets IT teams expanding memory capacity in dense compute or virtualisation clusters where error correction and registered signalling are mandatory.

Upgrade from smaller DDR5 RDIMM configurations

Replacing lower-capacity DDR5 RDIMM sets with this eight-module kit adds 512 GB in a single step when the XE8640 chassis and memory-controller population rules allow all slots to be filled. The jump is worth it when workloads exceed the current memory ceiling and the platform’s qualified-vendor list includes this part number.

512 GB capacity with ECC headroom

Eight 64 GB dual-rank modules deliver 512 GB of registered ECC memory at 4800 MT/s and CL40 latency, operating at 1.1 V. The kit comfortably handles large in-memory databases, heavy virtual-machine density and checkpoint-intensive HPC jobs, while the registered buffer and ECC maintain signal integrity across all populated channels until the platform’s maximum supported capacity is reached.
