4LFF Rack Server with Xeon Gold 6246R
The Dell PowerEdge R640 is a 1U rack-mount server fitted with one Intel Xeon Gold 6246R processor running at 3.4 GHz and 16 cores. It ships with 128 GB of DDR4 ECC registered memory and a PERC H740P RAID controller. The 4LFF chassis accepts up to four 3.5-inch SATA drives, which are not included. Remote management is provided by iDRAC9 Enterprise.
Dual 750 W power supplies and integrated graphics
Two 750 W power supplies deliver redundant power for the single-socket configuration. Integrated graphics handle console output without a discrete GPU, keeping heat and acoustic output low in typical rack environments. The system includes a 10 GbE two-port 562T network adapter for high-throughput connectivity. Firmware and BIOS are updated to the latest stable release before dispatch.
Room for a second CPU and massive memory expansion
The motherboard supports a second Xeon processor, doubling core count when workloads grow. Memory capacity scales to 7.68 TB across DDR4 slots, freeing budget for future upgrades instead of an oversized initial purchase. Four 3.5-inch drive bays leave flexibility for capacity or performance storage mixes. Rail kit is available on request for standard rack installation.

Questions about this item
What rail kit do I need to mount this 1U R640 chassis in a standard rack?
The listing notes a rail kit is available on request; order the Dell sliding rail kit that matches the R640 4LFF chassis to secure the 36 x 24 x 10 in server in a standard rack.
Which memory modules should I order when the 128 GB of DDR4 ECC registered RAM needs expansion?
Add Dell-certified DDR4 ECC registered DIMMs; the board supports up to 7.68 TB total, so populate the remaining slots with matching speed and rank modules.
At what point does the dual 750 W power supply become the limiting factor during sustained load?
The two 750 W units share the load; continuous draw above roughly 750 W leaves no redundancy, so plan workloads to stay under that threshold.
