Overclocking Locked Intel CPU
Overclocking Locked Intel CPU
I'm checking if my i5-8400 can be overclocked with the Gigabyte Aorus Gaming Z370 Wi-Fi. The monitor shows 3900 MHz, but I think it's already fully locked, so maybe nothing will change. I've enabled the speed shift feature, but I'm unsure if that helps. Is this device overclocked or is there another way?
The information provided is not fully accurate. It's possible to exceed the standard BCLK frequency (formerly known as Front Side Bus or FSB) beyond the default 100MHz. For instance, a chip with a 28x multiplier operating at 100MHz would achieve a base speed of 2.8GHz. Increasing BCLK further to 105MHz could lead to instability issues. Even if successful, the effective speeds would be around 2.94GHz base and 4.095GHz boost, which wouldn't offer significant real-world benefits. Many builders in the past preferred investing in K-series chips and Z-series boards for better performance.
The information provided isn't fully accurate. You can indeed increase the BCLK speed beyond the standard 100MHz, such as using a 28x multiplier on a 100MHz clock, resulting in a base speed of around 2.8GHz. However, pushing it further to 105MHz could lead to instability issues. Even if successful, the effective speeds would be much lower—approximately 2.94GHz base and 4.095GHz boost—which wouldn't justify the effort in real-world scenarios. Many builders have preferred investing in K-series chips and compatible Z-series boards instead. The 3.9GHz speed implies using boost with 2 to 5 cores, but the boost speed under load drops to about 3.8GHz. I'm also puzzled by your choice of a Z-series board paired with a non-K series chip.
