Virtualization-ready rack server
The Dell PowerEdge R640 is a 1U rackmount server system designed for business workloads such as virtualization, databases, file storage and application hosting. It ships with two Intel Xeon Gold 6154 processors, each running at 3.0 GHz with 18 cores for a total of 36 cores. The system includes 512 GB of DDR4 memory to support multiple virtual machines and data-heavy applications.
High-density compute for data centres
This server suits IT teams building dense compute clusters in rack environments where core count and memory capacity matter more than local storage. Organisations that require pre-installed operating systems, large internal drive arrays or GPU acceleration for AI workloads should evaluate alternative platforms. The chassis provides ten 2.5-inch drive bays without drives installed, letting buyers select capacity and media type independently.
512 GB DDR4 with 3 TB ceiling
The installed 512 GB of DDR4 memory comfortably handles dozens of concurrent virtual machines, database instances and backup jobs. Headroom extends to a maximum of 3 TB across the platform, allowing significant expansion as workloads grow. Dual Xeon Gold 6154 CPUs deliver 36 threads at 3.0 GHz, scaling well for multi-threaded services until memory bandwidth or I/O throughput becomes the limiting factor.

Questions about this item
What drive size and count do the 10 bays accept for this R640?
The server provides 10 front-accessible 2.5-inch bays; you supply the 2.5-inch drives that match your capacity and type requirements.
Will my existing DDR4 RDIMMs work with the two Gold 6154 CPUs already installed?
Yes, the system runs DDR4 memory and the two Gold 6154 processors are already seated, so compatible DDR4 RDIMMs can be added up to the 3TB maximum.
How can I confirm both Xeon Gold 6154 CPUs and all 512GB of memory are active after first boot?
During POST the firmware reports two processors, 36 total cores at 3.00GHz, and 512GB DDR4 detected; the iDRAC dashboard shows the same counts once the OS loads.
