DELL PowerEdge R640 8B 2× Xeon Gold 5122 512GB DDR4 8× 1.2TB SAS

Compact 1U rack server for virtualization

The Dell PowerEdge R640 fits two Xeon Gold 5122 processors running at 3.60GHz with 12 total cores and 16 threads. 512GB of DDR4 ECC registered memory supports dense virtual machine deployments and memory-intensive applications. Eight hot-swappable 1.2TB 10K SAS drives connect through a PERC H740P controller for high-speed transactional storage. Dual 10GbE and dual 1GbE ports handle network traffic in a 1U chassis.

Suited for virtualization hosts

This configuration targets businesses running hypervisors, databases, or hybrid storage systems that benefit from fast SAS storage and high core-count CPUs. The eight populated 2.5-inch bays leave no empty slots for additional drives without external enclosures. Integrated graphics only means no GPU compute capability for AI or rendering tasks. Buyers needing more than 512GB RAM or empty drive bays for expansion should consider other configurations.

512GB DDR4 ECC registered memory capacity

The installed 512GB DDR4 ECC registered memory determines how many virtual machines or data-heavy applications can run simultaneously. The system supports up to 3TB maximum capacity across available DIMM slots for future growth. DDR4 is the only memory generation compatible with this platform. This specification directly decides whether the server meets your workload density requirements.
