Ready for compute-heavy workloads
The Dell PowerEdge R640 is a 1U rack server built around a single Intel Xeon Gold 6148 processor running at 2.4 GHz with 10 cores and 27.5 MB cache. It ships with 256 GB of DDR4 ECC registered memory across sixteen 16 GB modules. The PERC H740P RAID controller manages up to four 3.5-inch SATA drive bays. Remote management is handled by iDRAC9 Enterprise.
Check rack space and storage needs
The chassis measures 36 by 24 by 10 inches and weighs 40 pounds, so verify your rack depth and weight allowance before ordering. No drives are installed; you must supply SATA drives compatible with the four-bay backplane. The system includes a 10 GbE dual-port 562T adapter, so confirm your switch ports and cabling support that speed. A second processor can be added later if workloads grow.
Dual 750 W supplies handle peak load
Two 750 W power supplies provide redundancy and share the load during normal operation. The single CPU and memory configuration keeps typical power draw well within that envelope. Integrated graphics and the iDRAC module add minimal heat. Expect fan noise consistent with a 1U density-optimised server under sustained compute tasks.

Questions about this item
Does the R640 ship with any drives or must I supply my own 3.5" SATA drives?
The chassis has four 3.5" bays and no drives are installed; you must add SATA drives yourself.
Should I choose the single 6148 processor or add a second one for my workload?
One Xeon Gold 6148 at 2.4GHz with 10 cores is installed; a second socket is empty and can be populated later.
What does the 256GB DDR4 figure mean for actual memory bandwidth and capacity headroom?
Sixteen 16GB modules fill 16 slots giving 256GB ECC registered DDR4; the platform supports up to 7.68TB total.
