Purpose-built 1U server

The Dell PowerEdge R640 is a 1U rack server equipped with two Intel Xeon Silver 4110 processors running at 2.1GHz and 768GB of DDR4 ECC registered memory. It includes a PERC H740P RAID controller and a 10GbE 2-port 562T adapter, while drive bays are empty for custom storage. Integrated graphics handle basic display output and iDRAC9 Enterprise enables full remote management.

Ideal for memory-heavy workloads

This configuration suits virtualisation hosts, database nodes or analytics clusters that need large RAM capacity and dual-socket compute in a single rack unit. Buyers who require installed drives, GPU acceleration or a different drive-bay count should look at other chassis options.

768GB DDR4 installed memory

The system ships with 768GB of DDR4 ECC registered memory populated across the available slots, reaching a substantial fraction of the 7.68TB maximum capacity. This single figure determines whether the server meets the working-set requirements of the target application.

Questions about this item

Will the 768GB DDR4 memory need to be replaced with higher-capacity modules as workloads grow?

The R640 supports up to 7.68TB of DDR4 across its slots, so the installed 768GB can be expanded by adding modules rather than replacing them.

Which component reaches its limit first when both Xeon Silver 4110 CPUs run at 2.1GHz continuously?

The dual 750W power supplies set the sustained power ceiling; CPU thermal design and the PERC H740P controller are rated for continuous operation within that envelope.

How much noise and heat do the dual 750W supplies and iDRAC9 produce during 24/7 operation?

The 1U chassis uses high-speed fans to move air across the CPUs, memory and PERC H740P; acoustic output is typical for a dense rack server and heat is exhausted out the rear.
