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.

Questions about this item

Which CPU configuration should I pick for the PowerEdge R640?

This unit ships with two Xeon Silver 4116 processors, each running at 2.1 GHz with 12 cores. The socket is LGA 3647 and the board supports a maximum of two CPUs, so the installed pair already fills every socket.

What does 768 GB of DDR4 mean for actual workloads?

The system arrives with 768 GB of DDR4 2400 MHz registered ECC memory spread across 24 slots (24 × 32 GB). The platform can scale to 3 TB, leaving 12 empty DIMM slots for future expansion.

What storage interface does the PERC H730P use and what does it limit?

The PERC H730P controller connects the eight 800 GB SATA SSDs over a 12 Gb/s SAS/SATA link and supports RAID 0, 1, 5, 6, 10, 50 and 60. Drive throughput is capped by the SATA 6 Gb/s interface of the installed SSDs.
