Dual-socket 1U server for dense compute

The PowerEdge R640 packs two Xeon Platinum 8160 processors into a single rack unit. Each CPU delivers 24 cores at 2.1 GHz with 3.7 GHz turbo. The platform targets scale-out workloads that need maximum throughput per rack slot.

Hot-swap bays, redundant power and rails

Eight 2.5-inch drive bays accept SAS or SATA media behind a PERC H730P controller with 2 GB cache. Two 750 W platinum supplies share the load and can be swapped without downtime. Ready rails and a front bezel ship with the chassis for immediate rack integration.

128 GB DDR4 registered ECC across 24 slots

Memory runs at 2666 MHz in an eight-module configuration leaving sixteen slots open for expansion toward the 3 TB ceiling. Buyers who need larger capacity per module or faster memory speeds must look elsewhere.
