Dense dual-socket 1U server

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out computing. Two Intel Xeon Gold 6148 processors deliver 40 total cores at 2.4 GHz with 3.7 GHz turbo. 768 GB of DDR4 registered ECC memory fills all 24 slots. Eight 800 GB SATA SSDs sit behind a PERC H730P controller with 2 GB cache.

Suits virtualization and database clusters.

This configuration targets hypervisor hosts, in-memory databases and high-thread-count applications that benefit from dual-socket density. The 1U chassis leaves no room for full-length accelerators, so buyers who need GPU compute or additional PCIe cards should look at larger platforms. Network connectivity is handled by an Intel X520/I350 daughter card with quad ports.

24 DIMM slots at 2666 MHz DDR4

Memory capacity maxes out at 3 TB across 24 slots running DDR4 2666 MHz registered ECC. The installed 768 GB uses every slot with 32 GB modules, so any expansion requires replacing existing DIMMs. Verify your workload fits within this ceiling before ordering.

Vragen over dit artikel

How can I verify the dual Xeon Gold 6148 CPUs are running at 2.4GHz with 20 cores each after installation?

Use iDRAC9 Enterprise or the system BIOS to confirm both processors show 20 cores at 2.4GHz base clock with 3.7GHz turbo capability.

What components are included and which must be purchased separately for this R640?

Included: 2x Xeon Gold 6148, 768GB DDR4 (24x 32GB), H730P controller, 8x 800GB SATA SSDs, X520/I350 quad-port NIC, iDRAC9 Enterprise, 2x 750W PSUs, rails, bezel. No additional parts required for operation.

Which memory configuration should I choose if I need to expand beyond the installed 768GB?

All 24 DDR4 slots are populated with 32GB modules. To increase capacity, replace existing modules with larger DDR4 RDIMMs up to the 3TB maximum supported by the C620 chipset.
