DELL PowerEdge R640 4LFF Xeon Gold 6142 256GB DDR4

Dell PowerEdge R640 4LFF Server

The Dell PowerEdge R640 is a 1U rack-mount server system built around a single Intel Xeon Gold 6142 processor running at 2.6GHz with 16 cores and 22 MB cache. It ships with 256GB of DDR4 ECC registered memory installed across sixteen 16GB modules. The chassis provides four 3.5-inch drive bays and includes a Dell PERC H740P RAID controller for SATA storage. Remote management is handled by iDRAC9 with an Enterprise license.

Virtualisation hosts and memory-heavy workloads

This configuration suits buyers who need high core density and large memory capacity in a compact 1U form factor for virtualisation, database or compute tasks. The single processor leaves one socket open for future expansion up to two CPUs. Buyers who require GPU acceleration, front-access high-speed storage bays or a second processor installed from day one should look at a different chassis. The integrated graphics and 10GbE 2-port 562T adapter cover basic display and networking needs without add-in cards.

256GB DDR4 ECC registered memory installed

The installed memory totals 256GB using sixteen 16GB DDR4 ECC registered DIMMs, a significant factor for workloads that depend on memory capacity and error correction. The platform supports a maximum of 7.68TB when fully populated across both processor sockets. Buyers planning to reach that ceiling must add a second processor and additional DIMMs, as the current single-CPU configuration limits the usable slot count.
