mean sure there are those automatic one-click solutions that can give a quick and dirty boost to your CPU but if you want to do it yourself you end up looking at all these confusing options in your UEFI BIOS instead of just a dial that you can turn to make the pc go faster and one thing that's easy to get confused by is the base clock and something called the CPU multiplier which together determine your CPU speed but what the heck are these things and why is it that they are separated out instead of just having one field where you punch in your desired CPU frequency it's a great question because even many enthusiasts are only familiar with overclocking with the multiplier and i get why the easiest way to adjust your CPU speed is to ignore everything else and bump up the multiplier adding voltage when it becomes unstable this approach does have some drawbacks though unless you're running AMD you will need to buy an unlocked k or x series processor and on both the blue and red team you'll need to buy a supported motherboard furthermore multiplier overclocking doesn't offer very fine control so if your system is let's say stable at 4.5 gigahertz but then crashes immediately at 4.6 who's to say that it might not have been also stable at 4.57 you could be leaving performance on the table with this method so now let's move on to the base clock so as it turns out your CPU GPU and RAM are not the only things inside your system that have a speed rated in megahertz and the base clock's job is to keep your pc's components in sync with each other so the base clock is provided by your chipset and you can learn more about chipsets up here but what you need to know for now is that the chipset basically serves as a kind of coordinator between your CPU and your other components and this base clock will tend to be much lower than the rated speeds of your processor and your memory a common default base clock is just a hundred megahertz but while that might be adequate for some hypothetical low speed controller or something it would be incredibly slow for a modern CPU so that is why your processor uses a multiplier that allows it to run multiple cycles for every one system cycle provided by your base clock it's really hard it's like you know this whole thing so if you have a processor that's rated for 3.5 gigahertz what's happening is that by default your system is probably running a 100 megahertz base clock with a 35 times multiplier so this base clock times multiplier paradigm lets your CPU match up with the rest of your computer while still allowing it to run at a high speed and even though many cpus actually have a high tolerance for overclocking even further many other components such as your pci express lanes or your SATA controller
