DELL PowerEdge R640 1U rack server 2x Xeon Gold 5118 2.3GHz 12-core 256GB DDR4 2x 800GB SSD H730P

Dense dual-socket 1U server

The Dell PowerEdge R640 packs two Xeon Gold 5118 processors into a single rack unit, delivering 24 cores at 2.3 GHz with turbo up to 3.2 GHz. It ships with 256 GB of DDR4 ECC memory across 24 slots and a PERC H730P controller managing two 800 GB SATA SSDs. Quad-port networking adds two 1 GbE and two 10 Gb SFP+ links, while iDRAC9 Enterprise handles remote management. Redundant 750 W platinum supplies, rails and bezel complete the package for scale-out deployments.

Sustained load behaviour

Dual Gold 5118 CPUs maintain 2.3 GHz base frequency across all 24 cores under continuous workloads, with turbo headroom to 3.2 GHz when thermal budget allows. The H730P controller’s 2 GB cache and battery-backed write-back accelerate sustained write streams to the enterprise SATA SSDs. Redundant platinum power supplies share load evenly, reducing per-unit stress during prolonged operation. ECC memory corrects single-bit errors in-flight, preserving data integrity during extended compute runs without intervention.

Pre-order checklist

Verify rack depth and airflow clearance for a 1U chassis with front-to-rear cooling before installation. Confirm SFP+ transceiver compatibility for the 10 Gb ports and cable type for the 1 GbE links. Ensure 24 DDR4 slots match your memory expansion plan up to the 3 TB maximum. Check that the LGA 3647 socket and C620 chipset align with any planned processor changes, noting the two-socket limit. Validate operating system and hypervisor support for the PERC H730P RAID modes and iDRAC9 Enterprise features.
