Dual-socket 1U server for dense compute

The Dell PowerEdge R640 is a 1U rackmount server with two Intel Xeon Gold 6142 processors, each running at 2.6 GHz with 16 cores. It ships with 768 GB of DDR4 2666 MHz registered ECC memory across 24 slots and a PERC H730P 2 GB RAID controller supporting RAID 0, 1, 5, 6, 10, 50, 60 and pass-through. Two 300 GB 10K SAS drives, a quad-port 1/10 GbE network daughter card, iDRAC9 Enterprise, redundant 750 W platinum power supplies, rails and a bezel complete the unit.

Suited for virtualization clusters needing maximum

This configuration fits environments that need dual-socket performance, large memory capacity and hardware RAID in a single rack unit. The 24 DIMM slots are fully populated, so no further memory expansion is possible without removing modules. Buyers who require more than two processors, additional drive bays beyond the eight 2.5-inch slots, or a different storage interface should evaluate other platforms.

768 GB DDR4 in 24 populated slots

The installed memory uses all 24 DDR4 slots with 32 GB modules, reaching 768 GB total. Any memory upgrade requires replacing existing DIMMs because no free slots remain. Verify that your workload can operate within this capacity before purchasing.
