DELL PowerEdge R640 4LFF Xeon Gold 5120 2.2GHz 14C 256GB DDR4 No Drive

Dell PowerEdge R640 4LFF server

The Dell PowerEdge R640 4LFF is a 1U rack-mount server equipped with a single Intel Xeon Gold 5120 processor running at 2.2GHz with 14 cores and 256GB of DDR4 ECC registered memory. It includes a PERC H740P RAID controller and a dual-port 10GbE 562T network adapter. The chassis supports up to four 3.5-inch SATA drive bays and ships without any drives installed. This configuration targets businesses needing dense compute and memory capacity in a compact form factor.

Verify rack space power and cooling

Before ordering confirm that your rack provides at least 36 inches of depth and 24 inches of width to accommodate the chassis dimensions. Ensure the facility can supply adequate power for the dual 750W power supplies and that cooling capacity matches the 40-pound unit's thermal output. Check that your existing SATA drives are 3.5-inch form factor and compatible with the PERC H740P controller. The iDRAC9 Enterprise licence enables remote management but requires a dedicated network connection.

Add drives rails and a second CPU to complete

The four 3.5-inch bays free you to choose any SATA HDD or SSD capacity up to the controller limits. Installing a rail kit simplifies rack mounting and service access. The motherboard supports a second Xeon processor to double core count when workloads demand it. Memory can scale to 7.68TB using DDR4 modules across the remaining slots. The integrated graphics and 10GbE ports handle console and data traffic without extra cards.
