DELL PowerEdge R640 1U Rack Server 2x Xeon Gold 6148 2.4GHz 20 Core 512GB DDR4

Dense 1U dual-socket server

The Dell PowerEdge R640 is a 1U rack server built for high-density compute. It ships with two Intel Xeon Gold 6148 processors, each running at 2.4 GHz with 20 cores. The system includes 512 GB of DDR4 registered ECC memory across 16 modules. A PERC H730P controller and eight 2.5-inch drive trays provide internal storage connectivity.

Suited for virtualisation and scale-out workloads

This server fits environments that need maximum CPU cores and memory capacity in a single rack unit. The quad-port network card offers two 1 GbE and two 10 Gb SFP+ links for flexible fabric integration. Buyers who require GPU acceleration or more than eight drive bays should consider a larger chassis because this 1U form factor does not accommodate those expansions.

512 GB DDR4 registered ECC memory installed

The configured memory uses DDR4 2666 MHz registered ECC DIMMs, filling 16 of the 24 available slots. This capacity supports large virtual machine densities and in-memory databases directly. Verify that your workload fits within 512 GB or plan for additional modules up to the 3 TB maximum because memory type and slot count are fixed by the platform.
