Dual Xeon Silver 4114 server

The Dell PowerEdge R640 is a 1U rack-mounted server system equipped with two Intel Xeon Silver 4114 processors running at 2.2GHz. It targets organisations that need dense compute and large memory capacity for virtualisation, database or high-performance computing workloads. The chassis provides four 3.5-inch drive bays for flexible storage configuration.

Thermals and power draw

Dual 750W power supplies deliver redundancy for continuous operation in a 36 x 24 x 10 inch form factor weighing 40 units. The integrated iDRAC9 Enterprise remote management controller enables out-of-band monitoring of thermal sensors and power consumption without loading the host operating system.

Memory capacity and type

The system ships with 768GB of DDR4 ECC registered memory installed and supports a maximum of 7.68TB across its DIMM slots. Buyers who require a different memory population or faster processor frequencies must specify a custom configuration before purchase.

Questions about this item

How do I install drives into the 3.5-inch bays and which step is often missed?

Slide each drive into one of the four 3.5-inch bays until the carrier locks; the step people miss is configuring the PERC H740P RAID controller before the OS install.

What maintenance will the 750 W power supplies need later?

The two 750 W units are hot-swap; replace a failed module by sliding it out and inserting a new one without powering down the server.

What thermal limit appears first when both Xeon Silver 4114 CPUs run at 2.2 GHz continuously?

The 750 W power budget is reached before the cooling capacity, so sustained full-load operation may throttle if total draw exceeds the redundant supply rating.
