DELL PowerEdge R640 1U rack server 2x Xeon Gold 5118 2.3GHz 12-core 256GB DDR4 8x 600GB SAS H730P

Dense 1U Dual-Socket Platform

The Dell PowerEdge R640 is a 1U rack server built for scale-out data centre workloads. It ships with two Intel Xeon Gold 5118 processors, each running at 2.3 GHz with 12 cores and a 3.2 GHz turbo frequency. The system includes 256 GB of DDR4 registered ECC memory across eight 32 GB modules. Eight 600 GB 10K SAS drives and a PERC H730P controller provide high-performance internal storage.

Tool-Less Rails and Hot-Swap Components

Ready Rails and a front bezel are included for quick mounting in standard racks. Both 750 W platinum power supplies are hot-swappable, as are the eight 2.5-inch drive bays and system fans. The PERC H730P battery-backed cache requires a brief initial charge before write-back caching activates. Memory population follows strict rank-per-channel rules; incorrect DIMM placement will halt POST.

24 DDR4 Slots Define Maximum Capacity

The platform supports up to 3 TB of DDR4 across 24 slots, so the installed 256 GB leaves substantial headroom for future expansion. Only DDR4 registered ECC modules are compatible; other generations will not fit or function. The LGA 3647 sockets are fully populated, preventing any further CPU upgrades. Buyers needing more than two processors or non-ECC memory must choose a different architecture.
