PowerEdge R650 10-Bay 1U Server

The Dell PowerEdge R650 is a 1U rack server fitted with two Intel Xeon Silver 4310 12-core processors running at 2.1 GHz with a 3.3 GHz turbo. It ships with 256 GB of DDR4-2666 registered ECC memory across eight 32 GB modules and a PERC H755 RAID controller with 8 GB NV cache. Ten 2.5-inch SAS/SATA drive trays, a quad-port 1 GbE OCP 3.0 card, iDRAC9 Enterprise, dual 1400 W platinum power supplies, rails and a bezel complete the package.

Compatibility Check Before Ordering

Verify that your rack provides a 1U slot with sufficient airflow for a dual-processor server drawing up to 1400 W per supply. Confirm the PERC H755 controller meets your RAID-level requirements from the supported set of RAID 0, 1, 5, 6, 10, 50 and 60. Ensure your network infrastructure can use the four 1 GbE ports on the Broadcom 5720 OCP 3.0 adapter. Plan memory expansion within the 2 TB maximum across 32 DDR4 slots if future growth is expected.

Upgrade Path and When It Makes Sense

This system replaces an older 1U rack server that lacks 3rd Gen Intel Xeon Scalable performance, DDR4-3200 memory speed headroom or PCIe Gen4 bandwidth. The jump is worth it when workloads demand higher core counts, larger memory capacity or faster storage throughput than a previous-generation platform can deliver. It is not for buyers who need GPU acceleration, NVMe-only drive bays beyond the SAS/SATA trays supplied, or a tower form factor.

Questions about this item

What comes in the box and what do I need to buy separately?

The server ships with two Silver 4310 processors, 256 GB DDR4 in eight 32 GB modules, a PERC H755 RAID controller with 8 GB cache, ten 2.5" drive trays, a quad-port 1 GbE OCP 3.0 card, iDRAC9 Enterprise, two 1400 W platinum power supplies, rails and a front bezel. Drives and any additional memory must be purchased separately.

Which memory capacity should I choose for this R650?

The system arrives with 256 GB across 8 of 32 DDR4 slots and supports up to 2 TB total. Add matching 32 GB DDR4 2666 MHz registered ECC modules to fill remaining slots, or replace with higher-capacity DDR4 modules to reach the 2 TB limit.

What does the 2.1 GHz base clock mean once the server is running workloads?

Each Silver 4310 has 12 cores at 2.1 GHz base with a 3.3 GHz turbo frequency. Under sustained multi-threaded loads the processors will operate near the base clock, while bursty single-threaded tasks can reach the higher turbo speed within thermal limits.
