Dell PowerEdge R640 8B

The Dell PowerEdge R640 is a 1U rackmount server system built for business workloads such as virtualization, databases, and application hosting. It ships with dual Intel Xeon Gold 5122 processors and 512GB of DDR4 ECC registered memory installed.

Suited for memory-intensive tasks

This configuration suits organisations running in-memory databases, ERP systems, or virtualization clusters that need high capacity and strong single-thread performance. Buyers who require GPU acceleration, fibre-channel connectivity, or a different drive bay count should evaluate other platforms.

512GB DDR4 memory capacity

The installed 512GB DDR4 ECC registered memory is the decisive specification; it supports large-scale virtual machines and data-heavy applications while leaving headroom up to the 3TB maximum. Drives are not included, so storage capacity and type are chosen separately.

Questions about this item

How can I verify the dual 3.60GHz Xeon Gold 5122 processors and 512GB DDR4 memory are recognised after installation?

The front-panel LEDs for power and Ethernet will illuminate, and the system BIOS or iDRAC interface will display two 12-core CPUs at 3.60GHz with 512GB DDR4 ECC registered memory during POST.

What ships with the R640 and which components must be purchased separately?

The server includes the chassis, dual Xeon Gold 5122 CPUs, 512GB DDR4, H740P RAID controller, dual 10GbE X540 and dual 1GbE I350 ports, plus eight 2.5-inch drive trays; storage drives and an operating system are not included.

Should I choose the 512GB DDR4 configuration or plan to expand toward the 3TB maximum later?

The installed 512GB DDR4 ECC registered memory supports large-scale databases and virtualization clusters immediately; additional DDR4 modules can be added up to the 3TB limit if workloads grow.
