Why isn't Rated FSB displayed in CPU-Z checks for computers?

Buzz

When examining hardware specifications with CPU-Z, the absence of the Rated FSB line in CPU information raises questions. What causes this, and is this information significant?

Answer:

FSB (Front Side Bus) is the clock speed of the entire data channel from the CPU to the Mainboard. Typically, with older chip models, each clock cycle involves 4 data streams moving from the CPU to the Mainboard. The speed of these streams is measured by the Bus Speed parameter. You can find this information using CPU Z for older chip models. Simply install CPU Z, and the program will automatically collect the data for you.

However, presently, with the new chip models, when checking specifications using CPU-Z, the Rated FSB line does not appear. The reason behind this is that the FSB is the connection between the CPU and the Northbridge chip (MCH). Currently, in Intel's new chip models from Sandy Bridge onwards (Core i3, i5, i7 2xxx), this technology is no longer in use. Instead, the CPU directly connects to the memory, making the FSB bus nonexistent. This is why the Rated FSB line is not displayed in the CPU-Z software.

Additionally, you can refer to how to check the graphics card on a computer using CPU Z to understand the name and download the correct graphics card driver for your device.
