Dense 1U dual-socket server

The Dell PowerEdge R640 is a 1U rackmount system built for dense scale-out data center computing. It ships with two Intel Xeon Gold 6134 processors running at 3.2 GHz with 3.7 GHz turbo across eight cores each. The chassis includes 768 GB of DDR4 2666 MHz registered ECC memory across 24 slots and eight 1.2 TB 10K SAS drives.

Fits virtualisation clusters and database nodes

This configuration suits buyers who need high core density, large memory capacity and redundant 750 W platinum power supplies in a single rack unit. It also provides quad-port networking with two 1 GbE and two 10 Gb SFP+ links plus iDRAC 9 Enterprise remote management. Buyers who require more than 24 DIMM slots, more than eight 2.5-inch drive bays or more than two processor sockets should evaluate alternative platforms.

768 GB DDR4 registered ECC memory

The installed 768 GB of DDR4 2666 MHz registered ECC memory occupies all 24 DIMM slots and supports a maximum capacity of 3 TB. This single specification determines whether the system can handle the intended workload or if a different memory configuration is required.

Questions about this item

Does the Dell PowerEdge R640 require a specific rack depth for the included Ready Rails?

The server is a 1U rack unit and ships with Ready Rails for standard cabinets; verify your rack depth matches the chassis length before installation.

Can I mix the installed 2666MHz DDR4 ECC modules with slower DDR4 speeds in the remaining slots?

The system runs DDR4 at 2666MHz; populating empty slots with slower modules will downclock all memory to the lowest common speed.

How do I confirm the PERC H730P controller sees all eight 1.2TB SAS drives after first boot?

Open the controller BIOS or iDRAC 9 Enterprise storage view; all eight drives should appear as Ready with the configured RAID level showing Optimal.
