Dell PowerEdge R640 4x3.5" Server
The Dell PowerEdge R640 is a 1U rack-mount server system designed for dense compute environments. It arrives with two Intel Xeon Silver 4114 processors installed, each running at 2.2GHz with ten cores. The system includes 128GB of DDR4 ECC registered memory and a PERC H740P RAID controller. No storage drives are installed in the four 3.5-inch bays.
Suits virtualisation hosts needing dual CPUs
This configuration suits buyers who need dual-socket processing and high memory capacity in a compact 1U form factor. The four 3.5-inch drive bays support SATA hard drives for capacity-focused storage arrays. Buyers who need more than four drive bays, GPU acceleration, or a different drive form factor should look at a different chassis.
Four 3.5-inch drive bays define storage capacity
The chassis provides exactly four 3.5-inch drive bays connected to the PERC H740P controller via SATA. This bay count is the fixed limit for internal storage devices in this specific model. Buyers requiring a higher number of internal drives must select a different server platform.

Questions about this item
How do I install the Xeon Silver 4114 processors into the R640 and what step is commonly missed?
Align the processor notches with the socket keys, lower the carrier gently, and close the retention lever; the step often missed is applying the included thermal grease evenly before seating the heatsink.
What maintenance will the 750W power supplies and PERC H740P controller need over time?
Replace the 750W units if fan noise increases or voltage drifts; the H740P battery-backed cache module typically requires replacement after three to five years.
What thermal limit appears first when the dual 2.2GHz Xeons run sustained workloads in the 1U chassis?
The CPU package temperature reaches its throttle point before the 750W supplies hit their current ceiling, so adequate front-to-rear airflow is critical.
