Server System with Dual Xeon Platinum 8160

The Dell PowerEdge R640 is a 1U rack-mount server equipped with two Intel Xeon Platinum 8160 CPUs running at 2.1GHz, each providing 24 cores and 33MB cache. It comes populated with 768GB of DDR4 ECC registered memory across the available slots. Storage is managed by a Dell PERC H740P RAID controller supporting SATA drives, while networking includes a 10GbE dual-port 562T adapter and iDRAC9 Enterprise remote management.

Suited for memory-intensive virtualization

This configuration targets environments that need high core counts and large memory capacity in a compact 1U form factor with four 3.5-inch drive bays. The dual 750W power supplies provide redundancy for continuous operation. Buyers who require installed drives, GPU compute capability, or a different drive bay layout should consider other configurations.

768GB DDR4 ECC registered memory installed

The system arrives with 768GB of DDR4 ECC registered RAM already installed, leaving headroom up to the 7.68TB maximum supported capacity. This memory amount directly determines how many virtual machines or how large a dataset the server can handle effectively. Verify that your application licensing and workload sizing align with this installed capacity before deployment.

Questions about this item

How do I install the Xeon Platinum 8160 processors and what step is often missed?

Seat both CPUs in the two sockets, apply thermal paste evenly, torque the heatsink screws in a cross pattern, then connect the 10 Gb 562T adapter before first boot.

What maintenance will the 750 W power supplies and PERC H740P controller need later?

Replace the two 750 W units if fan noise rises or voltage drifts; swap the H740P battery module when the iDRAC9 alert shows capacity below threshold.

What limit appears first when the 768 GB DDR4 runs sustained workloads?

Memory bandwidth saturates at the 2.1 GHz Xeon clock before the 7.68 TB ceiling is reached, so add DIMMs in balanced channels to delay the bottleneck.
