DELL PowerEdge R640 1U Rack Server 2x Xeon Platinum 8160 2.1GHz 24 Core 256GB DDR4

Dense 1U dual-socket server

The Dell PowerEdge R640 packs two Intel Xeon Platinum 8160 processors at 2.1 GHz with 24 cores each into a single rack unit. It ships with 256 GB of DDR4 registered ECC memory across eight 32 GB modules and a PERC H730P controller managing two 300 GB 10K SAS drives. Quad-port networking adds two 1 GbE and two 10 Gb SFP+ links, while iDRAC9 Enterprise handles remote management. Redundant 750 W platinum power supplies and sliding rails complete the package.

Suits virtualization clusters needing maximum

Buyers who want more storage bays than the eight 2.5-inch slots provided should look elsewhere. The chassis does not accommodate 3.5-inch drives or additional drive cages. Workloads that require GPU acceleration or FPGA cards cannot use this 1U form factor. Teams needing single-thread performance above the 3.7 GHz turbo ceiling must consider other architectures.

24 cores per processor at 2.1 GHz base clock

Each Xeon Platinum 8160 delivers 24 cores running at 2.1 GHz with a 3.7 GHz turbo frequency. This core count and clock combination determines how many virtual machines or containers fit in the 1U envelope. The installed 256 GB of DDR4-2666 fills eight of twenty-four slots, leaving room to scale toward the 3 TB maximum if licensing or workload demands grow.
