Dual-socket 1U rack server with two 16-core Xeon Gold 6130 CPUs at 2.1 GHz, 768 GB DDR4, H730P RAID controller, two 300 GB SAS drives, quad-port 1 GbE and 10 GbE SFP+ networking, iDRAC 9 Enterprise.
The Dell PowerEdge R640 is a 1U rack server built for dense scale-out data centre computing. It ships with two Intel Xeon Gold 6130 processors, each running at 2.1 GHz with 16 cores. The system includes 768 GB of DDR4 registered ECC memory across 24 slots. A PERC H730P controller, dual 10 Gb SFP+ networking, and redundant 750 W power supplies complete the configuration.
This server suits environments that need high core counts and large memory capacity in a single rack unit. Virtualisation hosts, database clusters, and compute-heavy workloads benefit from the 32 total cores and 768 GB RAM. Buyers who need more than two processors, require storage interfaces beyond SAS or SATA, or operate with single-socket licensing constraints should evaluate alternative platforms.
The 24 memory slots set the practical upgrade limit for this chassis. With 768 GB installed as 24 × 32 GB modules, every slot is populated at DDR4 2666 MHz. Further expansion requires replacing existing DIMMs rather than adding to empty slots. The maximum supported capacity is 3 TB when higher-density modules are used.

Versi lain model ini
Keluarga yang sama, memori, penyejuk atau kelajuan jam yang berbeza — bandingkan sebelum membuat keputusan.
Each supply is rated at 750 W with platinum efficiency; actual draw depends on workload but the redundant pair shares the load to keep the system running continuously.
The chassis accepts standard 2.5-inch SAS or SATA drives; additional drives and matching hot-swap carriers are required for the remaining six bays.
The H730P supports 12 Gb/s SAS and is backward compatible with 6 Gb/s SAS drives, so existing drives will be detected and can be used in RAID arrays.
