PowerEdge R650xs 1U server

The Dell PowerEdge R650xs is a 1U rack server built for dense compute environments. It ships with two Intel Xeon Gold 6338 processors, each offering 32 cores at a 2.0 GHz base frequency and 3.2 GHz turbo. The system includes 64 GB of DDR4 3200 MHz registered ECC memory across four modules. This configuration targets virtualization, cloud infrastructure and high-performance computing workloads.

Thermals power and noise

Redundant hot-swap 1400 W platinum-efficiency power supplies handle the dual-processor load while allowing maintenance without downtime. The 1U chassis uses forced-air cooling tuned for the installed Xeon Gold 6338 CPUs and DDR4 DIMMs. Fan speeds scale with inlet temperature and processor utilisation to balance airflow and acoustic output in typical rack rows. Power draw varies with workload intensity across the 32 total cores.

RAID controller networking management

The PERC H745 front RAID controller adds 4 GB of non-volatile cache with battery backup and supports RAID 0, 1, 5, 6, 10, 50 and 60 across the eight 2.5-inch SAS/SATA trays. A Broadcom 5720 quad-port 1 GbE OCP 3.0 network card provides four RJ-45 links for management and data traffic. iDRAC9 Enterprise enables remote console, power control and firmware updates over a dedicated port. ReadyRails and a front bezel are included for immediate rack mounting.

Questions about this item

How do I install the Xeon Gold 6338 processors into the LGA 4189 sockets on this R650xs?

Align the processor triangle with the socket marker, lower it straight down without forcing, then secure the retention lever; the step often missed is applying the correct torque sequence on the heatsink screws so pressure stays even across the die.

Which components will need replacement first in the Dell Perc H745 controller with 4GB NV cache?

The cache battery typically reaches end of life after several years and should be swapped before it fails to avoid write-cache loss; fans and power supplies are hot-swap but last longer under normal load.

What thermal limit appears first when both 32-core CPUs run at 3.2 GHz turbo continuously?

The 1U chassis airflow hits its cooling ceiling before the CPUs throttle, so sustained all-core turbo requires inlet temperatures well below the maximum rated ambient to avoid automatic frequency reduction.
