Dual-socket 1U rack server

The Dell PowerEdge R640 is a 1U rack server built around two Intel Xeon Gold 5118 processors, each running at 2.3 GHz with 12 cores. It ships with 128 GB of DDR4 registered ECC memory across 24 slots and a PERC H730P RAID controller with 2 GB cache. Two 800 GB SATA SSDs and dual 750 W redundant power supplies are installed.

Suits dense virtualisation and scale-out workloads

This configuration fits environments that need high core counts and memory capacity in a single rack unit, such as virtualisation clusters, database nodes or high-performance computing. Buyers who require more than two processors, GPU acceleration, or storage interfaces beyond SATA and SAS should evaluate other platforms.

24 DDR4 slots support up to 3 TB

The motherboard provides 24 DDR4 DIMM slots with a maximum supported capacity of 3 TB, allowing significant memory expansion beyond the factory-installed 128 GB. This ceiling determines whether the server can grow with workload demands or if a larger chassis is needed.

Questions about this item

Does this 1U server include rails for a standard rack?

The server ships with Ready Rails and a front bezel for rack mounting.

How are the Xeon Gold 5118 processors installed, and what step is often missed?

Two processors are already installed in the LGA 3647 sockets; the common oversight is not confirming that both CPU power cables are fully seated.

When will the PERC H730P controller battery need replacement?

The RAID controller includes a battery-backed cache; plan to replace the battery module every three to five years to maintain write-back cache protection.
