DELL PowerEdge R640 4LFF Xeon Bronze 3106 1.7GHz 256GB DDR4 No Drive

Rack Server for Dense Compute

The Dell PowerEdge R640 is a 1U rack-mount server built for environments that need high memory density in a small footprint. It ships with a single Intel Xeon Bronze 3106 processor running at 1.7 GHz and 256 GB of DDR4 ECC registered memory. The chassis supports up to four 3.5-inch drive bays for local storage expansion.

Single Processor with Room to Grow

The system uses one of two available processor sockets, leaving a second socket open for a future CPU upgrade. Memory capacity reaches 7.68 TB across 24 DIMM slots, so the installed 256 GB leaves substantial headroom. A PERC H740P RAID controller manages the SATA drive bays, and dual 750 W power supplies provide redundancy. Remote management is handled by iDRAC9 Enterprise.

Memory and Storage Headroom

With 256 GB of DDR4 installed, the server comfortably runs virtualization hosts, database caches, or memory-heavy analytics workloads. The maximum 7.68 TB ceiling supports extreme in-memory datasets. No drives are included, so buyers must supply their own SATA disks; the four-bay limit means all-flash arrays or large-capacity spinners must fit within that constraint.
