DELL PowerEdge R640 4LFF 1x Xeon Gold 5218 128GB DDR4 No Drive Rack Server
A 1U rack server with one Xeon Gold 5218 at 2.3GHz, 128GB DDR4, PERC H740P controller and four 3.5-inch bays
- TypeRack
- CPU TypeIntel Xeon
- CPU Speed2.3GHz
- # of Processors Installed1
- MAX Processors2
- Installed Memory Size128GB
- 16-core Xeon Gold 5218 at 2.3GHz for strong compute density
- 128GB DDR4 ECC memory for reliable multitasking
- PERC H740P RAID controller with 2GB cache for storage performance
- Four 3.5-inch drive bays ready for SATA capacity scaling
- Dual 750W power supplies and iDRAC9 Enterprise for resilient management
Purpose-built compute density
The Dell PowerEdge R640 fits four 3.5-inch drive bays into a 1U rack chassis, providing dense local storage alongside a single Intel Xeon Gold 5218 processor running at 2.3 GHz with 16 cores and 22 MB cache. 128 GB of DDR4 ECC registered memory is installed, and the PERC H740P RAID controller manages the SATA backplane. Remote administration uses iDRAC9 with an Enterprise licence, while dual 750 W power supplies and a 10 GbE 562T two-port adapter handle power and networking.
Fit and gaps
This configuration suits teams that need a compact 1U server with integrated RAID and high-speed networking for virtualisation, database or file workloads where 128 GB of memory is sufficient. Buyers who require two processors from day one, more than four 3.5-inch bays, or installed drives should look at other chassis or populate the empty bays before deployment. The single-socket layout also limits maximum memory to half the 7.68 TB platform ceiling.
Deciding specification
The defining constraint is the four-bay 3.5-inch chassis paired with the PERC H740P controller, which fixes the internal storage topology to SATA hard drives or SSDs and caps raw capacity at the number of populated bays.

Questions about this item
What components are included in the Dell PowerEdge R640 box and what must be purchased separately?
The server ships with one Xeon Gold 5218 processor, 128GB DDR4 ECC Registered memory, a PERC H740P RAID controller, a 10GB 2-port 562T Ethernet adapter, two 750W power supplies and rails on request. No 3.5-inch drives are installed.
Which memory capacity should I choose for this R640 configuration?
The unit already contains 128GB DDR4 across its DIMM slots. The platform supports up to 7.68TB maximum, so additional modules can be added later if the workload demands more capacity.
What does the 2.3GHz Xeon Gold 5218 clock speed mean for actual performance in this rack server?
The processor runs at a base frequency of 2.3GHz with 16 cores and 22MB cache, providing strong multi-threaded throughput for virtualization, database and compute tasks within the 1U chassis.
