DELL PowerEdge R640 1U Rack Server 2x Xeon Gold 6148 2.4GHz 20-Core 256GB DDR4 2x 800GB SSD

Dual-Socket 1U Server for Dense Compute

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out workloads. It ships with two Intel Xeon Gold 6148 processors running at 2.4 GHz with 20 cores each, delivering 40 cores total. The system includes 256 GB of DDR4 2666 MHz registered ECC memory across 8 modules. Two 800 GB SATA SSDs and a PERC H730P RAID controller provide enterprise storage performance.

Suited for Virtualisation and Database Clusters

This configuration suits organisations running virtualisation hosts, database clusters or high-performance computing tasks that benefit from high core counts and redundant power. The dual 750 W platinum power supplies and iDRAC 9 Enterprise simplify fleet management. Buyers who need more than 24 DIMM slots, additional drive bays beyond the 8-bay 2.5-inch chassis, or a different network interface should evaluate other platforms.

24 DIMM Slots Supporting 3 TB Maximum Memory

The motherboard provides 24 DDR4 slots with a maximum capacity of 3 TB, allowing significant memory expansion beyond the installed 256 GB. This headroom supports memory-intensive applications such as in-memory databases or large virtual machine densities. The LGA 3647 socket and Intel C620 chipset define the processor compatibility for any future upgrades.
