Our recommended upgrade target is the Intel Xeon E3-1270. This CPU offers a significant step up in performance compared to the lower-end dual-core processors often found in the R210 II. The E3-1270 boasts four cores and eight threads (thanks to Hyper-Threading), a base clock speed of 3.4 GHz, and a Turbo Boost frequency of up to 3.8 GHz. This translates to a substantial increase in processing power, making it ideal for running multiple VMs or handling the demanding processing requirements of Frigate.
The key to this being a $30 upgrade lies in sourcing the CPU from the used market. Online marketplaces like eBay are often teeming with E3-1270 processors pulled from decommissioned servers. With a little patience, you can often find these CPUs for around $30 or even less.
Ensuring Compatibility:
Before purchasing a CPU, double-check that it’s compatible with your specific R210 II motherboard revision. While most E3-1200 series CPUs should work, it’s always best to verify compatibility to avoid any unforeseen issues. Consult the Dell support website or relevant online forums for a list of supported processors.
Step-by-Step Guide: Replacing the CPU in Your R210 II
Replacing the CPU in a Dell PowerEdge R210 II is a straightforward process, requiring only basic tools and a few minutes of your time.
Power Down and Disconnect: Begin by completely powering down the server and disconnecting it from the power outlet. This is a crucial safety precaution to prevent electrical shock and damage to the hardware.

Performance Gains: Proxmox and Frigate Benchmarks
The performance gains from this simple CPU upgrade are significant, particularly when running demanding applications like Proxmox and Frigate. We conducted a series of benchmarks to quantify the improvements.
Proxmox Virtualization:
With the original dual-core CPU, we were limited to running a maximum of two or three VMs concurrently without experiencing significant performance degradation. After upgrading to the E3-1270, we were able to comfortably run five to six VMs, with each VM exhibiting noticeably improved responsiveness. The additional cores and threads provided the necessary resources to handle the increased workload.
We also observed a significant reduction in CPU utilization across the Proxmox host. Tasks that previously maxed out the CPU now consumed a much smaller percentage of the available resources, leaving more headroom for other processes.
Frigate Object Detection:
Frigate, with its real-time object detection capabilities, is notoriously CPU-intensive. With the original dual-core CPU, Frigate struggled to keep up with the video streams from our security cameras, resulting in missed events and delayed notifications. The object detection process was often slow and unreliable.
After upgrading to the E3-1270, Frigate’s performance improved dramatically. The object detection process became significantly faster and more accurate, with fewer missed events and more timely notifications. The CPU utilization also decreased substantially, allowing Frigate to run more efficiently and reliably. We also noticed that the frame rate of the video streams increased, resulting in a smoother and more responsive viewing experience.
