DELL PowerEdge R640 4LFF 2x Xeon Gold 6226R 32GB DDR4

Rack server with four 3.5-inch bays

The Dell PowerEdge R640 is a 1U rack-mount server populated with two Xeon Gold 6226R processors running at 2.9 GHz. Sixteen cores per CPU deliver 32 threads for virtualization, database or compute workloads. The system ships with 32 GB of DDR4 ECC registered memory across two 16 GB modules. A PERC H740P RAID controller manages up to four 3.5-inch SATA drives, which are not included.

Suited for dense storage workloads.

This configuration targets buyers who need high core counts and local 3.5-inch storage in a single rack unit. The integrated graphics and lack of PCIe add-in cards make it unsuitable for GPU-accelerated tasks or workloads requiring dedicated graphics. Buyers who need more storage bays, additional network ports or pre-installed drives should look at other chassis options. The 10 GbE dual-port adapter supports high-throughput networking out of the box.

Dual Xeon Gold 6226R at 2.9 GHz with 22 MB cache

Each of the two installed processors provides 16 cores and 22 MB of cache at a base frequency of 2.9 GHz. This CPU choice defines the server's compute ceiling and memory-channel count, directly determining whether the platform matches the performance envelope of the intended workload. The 7.68 TB maximum memory capacity allows future expansion well beyond the factory 32 GB.
