Dual-Socket Xeon Gold 5218 Server

The Dell PowerEdge R640 is a 1U rack server equipped with two Intel Xeon Gold 5218 processors running at 2.3GHz. It provides 32GB of DDR4 ECC registered memory across two 16GB modules. The chassis supports up to four 3.5-inch SATA drive bays and includes a PERC H740P RAID controller. Remote management is handled by iDRAC9 with an Enterprise licence. This unit ships without installed drives.

Dual 750W Supplies and Efficient Cooling

Redundant 750W power supplies deliver N+1 resilience for the 16-core processors and memory. The 1U form factor uses front-to-rear airflow optimised for dense rack rows. Integrated graphics and the 10GbE 562T two-port adapter add minimal thermal load. Fan speeds scale with inlet temperature to keep acoustic output low in typical data-centre aisles.

Sustained Load Stability Across 16 Cores

Under continuous multi-threaded workloads the dual 5218 CPUs maintain their 2.3GHz base frequency across all 16 cores per socket. The 22MB cache per processor reduces memory latency during long compute runs. ECC DDR4 protects data integrity over extended periods. The PERC H740P controller sustains RAID parity calculations without throttling. The platform supports up to 7.68TB of memory for future expansion.

Questions about this item

How do I install the 3.5-inch drives into the four front bays and which step is often missed?

Slide each drive into a bay until the carrier clicks, then verify the PERC H740P RAID controller detects every disk in the iDRAC9 interface before creating arrays.

What maintenance will the 750 W power supplies and system fans need over time?

Check fan speeds and power-supply health in iDRAC9 monthly; replace a supply if its status turns amber or fans report sustained RPM above the baseline.

What limit appears first when both Xeon Gold 5218 CPUs run at 2.3 GHz continuously?

The dual 750 W power supplies set the hard ceiling; sustained full-core load can draw more than the combined rating, causing the system to throttle.
