Server system for dense compute
The Dell PowerEdge R640 is a 1U rack server fitted with one Xeon Silver 4114 processor at 2.2GHz and 256GB of DDR4 ECC registered memory across sixteen slots. It includes a PERC H740P RAID controller and a dual-port 10GbE 562T adapter. The chassis supports up to four 3.5-inch SATA drives and ships with two 750W power supplies.
Suits virtualisation hosts needing maximum memory
This configuration suits buyers who need high core-count density and large memory capacity in a single rack unit for virtualisation or database workloads. It does not suit buyers who want installed storage drives, a second processor populated from the factory, or GPU-accelerated compute because the system uses integrated graphics only.
256GB DDR4 ECC registered memory decides fit
The installed memory uses DDR4 ECC registered modules totalling 256GB across sixteen 16GB DIMMs. Buyers whose applications require a different memory generation, non-ECC modules, or a lower starting capacity must request a custom build before ordering.

Questions about this item
How much power do the dual 750W supplies draw when the R640 runs a 2.2GHz Xeon Silver 4114 all day?
The system ships with two 750W power supplies; actual draw depends on workload, but the units provide redundant 750W capacity for the installed 10-core processor.
Which drive trays and cables must I already have to populate the four 3.5-inch bays?
The 4LFF chassis accepts four 3.5-inch SATA drives; you need compatible 3.5-inch drive carriers and SATA data cables for each bay.
Will the PERC H740P controller recognise older SATA drives I keep from a previous server?
Yes, the H740P RAID controller supports SATA drives, so legacy SATA disks can be used in the four 3.5-inch bays.
