DELL PowerEdge R640 1U rack server 2x Xeon Silver 4116 2.1GHz 12-core 768GB DDR4 8x 800GB SSD

Dual-socket 1U server for dense compute

The Dell PowerEdge R640 packs two Intel Xeon Silver 4116 processors into a single rack unit, delivering 24 cores at 2.1 GHz with 3.0 GHz turbo. It ships with 768 GB of DDR4 ECC memory across all 24 slots and eight 800 GB SATA SSDs on a PERC H730P RAID controller. Dual 750 W platinum power supplies and iDRAC9 Enterprise remote management complete the package.

Suited to virtualisation and database clusters

This configuration targets workloads that need high core counts and large memory capacity in minimal rack space. The filled memory slots and fixed eight-drive chassis leave no room for internal storage expansion, so buyers who want more drive bays or additional memory headroom should look at a different platform.

24 occupied DIMM slots cap memory upgrades

All 24 DDR4 slots are populated with 32 GB modules, so the installed 768 GB cannot be increased without removing existing memory. Any future expansion requires replacing modules rather than adding them.
