Can't boost i7-7820HK to 2.9Ghz - Alienware 15R3
There isn’t much more to say. Your computer seems to be performing well. If you wish to experiment with undervolting, adjust the core and cache offset voltages to roughly -50 mV to -75 mV. I’m new to the 7820HK and these values are just a bit unclear. Most Intel CPUs handle those settings without issues. When testing, set both voltages in unison at the beginning. For certain Intel processors, users often achieve better outcomes by increasing the core offset more than the cache offset.
After configuring your voltages, perform some stability checks. I find the TS Bench 960M test useful—it’s a straightforward and quick assessment. If it flags any errors or crashes during testing, your undervolt settings may be unstable. The settings might be too aggressive; consider raising the voltage slightly to stabilize things. This applies to any stability evaluation.
I also recommend running Cinebench. While it isn’t ideal for stability testing on most CPUs, it can indicate whether undervolting offers any advantages. You should notice reduced power usage and temperatures, improved performance, or a combination of both.
Edit – When the desktop is idle with only ThrottleStop enabled, aim to minimize C0% as much as possible. Cutting down unnecessary background processes can noticeably boost overall performance. Check the Task Manager under the Details section for tasks that consume excessive CPU cycles and aren’t essential 24/7.
The OC manages part of Command Center but it doesn't function properly. I keep receiving error messages about configuration files being unable to download, and I can't even activate the Overclocking slider. Before, I removed Command Center because it seemed unnecessary and I don't want flashy lights or other distractions. It only helps with overclocking, but it doesn't work at all.
My setup has remained stable at 4.1GHz for several weeks now.
