Dell PowerEdge XE9640 memory kit

This 128 GB kit uses eight 16 GB DDR5 modules built for the Dell PowerEdge XE9640 server. Registered ECC design adds error correction and signal buffering that enterprise workloads require.

Capacity and headroom

Eight slots filled with 16 GB RDIMMs deliver 128 GB total at DDR5 4800 PC5-38400 speed. CL40 latency and 1.10 V operation suit standard server profiles; the kit reaches its limit when the platform demands higher frequencies or lower latencies.

What the bundle changes

The matched 8 x 16 GB pack removes the guesswork of mixing ranks or vendors across all populated channels. Single-rank 1Rx8 organisation keeps electrical loading predictable for the memory controller.
