DELL PowerEdge R640 1U rack server 2× Xeon Gold 6142 2.6 GHz 16-core 768 GB DDR4 H730P 2× 800 GB SSD

Dual-socket 1U rack server

The PowerEdge R640 is a 1U rack server equipped with two Intel Xeon Gold 6142 processors running at 2.6 GHz with 16 cores each. It provides 768 GB of DDR4 registered ECC memory across 24 slots and includes a Dell PERC H730P 2 GB storage controller with battery-backed cache. Two 800 GB SATA SSDs are installed in the 2.5-inch drive bays, and a quad-port network daughter card adds two 1 GbE and two 10 Gb SFP+ connections. iDRAC9 Enterprise and redundant 750 W platinum power supplies complete the platform.

Suited for dense virtualization.

This configuration suits organisations running dense virtualization, high-performance computing or database workloads that benefit from 32 total cores and a large memory footprint. The 24 DIMM slots allow expansion up to the platform maximum of 3 TB. Buyers who need more than eight 2.5-inch drive bays or who require a different drive interface should consider alternative chassis designs. The fixed 1U height limits PCIe expansion to low-profile cards only.

768 GB DDR4 registered ECC memory installed

The system ships with 768 GB of DDR4 2666 MHz registered ECC memory populated across all 24 slots. This capacity determines how many virtual machines or in-memory datasets can run simultaneously without swapping. Memory type and speed are fixed to DDR4 registered ECC; other generations or unbuffered modules are not compatible. Verifying the application memory requirement against this installed total is the primary step in confirming suitability.
