To upgrade a CPU, confirm the new chip matches your motherboard’s socket, update the BIOS if the board needs it for that CPU, power down, remove the cooler and old CPU, fit the new one, reapply thermal paste, and reinstall the cooler. Then boot and confirm Windows sees the new CPU.
- The new CPU must match your motherboard’s socket type.
- Some boards need a BIOS update before a newer CPU will boot.
- Reapply thermal paste every time you remove the cooler.
- Laptop CPUs are almost always soldered and cannot be upgraded.
Check Compatibility First
The CPU must physically match your motherboard’s socket, such as Intel LGA1700 or AMD AM5. Even within the same socket, some boards need a BIOS update to recognize newer CPUs, especially older boards paired with a chip released after the board. See CPU compatible with motherboard to check before buying.
Step by Step
1. Update the BIOS if needed
Check your motherboard maker’s support page, such as ASUS Support or MSI Support, for a CPU compatibility list. If your new CPU needs a newer BIOS, update it with your current CPU still installed, since some boards won’t boot at all with an unsupported chip until the BIOS is updated.
2. Power down and prepare
Shut down, unplug the PC, and touch bare metal on the case to discharge static. Have new thermal paste ready, since you’ll need to reapply it.
3. Remove the cooler
Unclip or unscrew the cooler and lift it off. It may need a gentle twist to break the old thermal paste’s seal.
4. Remove the old CPU
Lift the socket’s retention arm, and the old CPU should lift out easily. Never force it, and handle it by the edges only.
5. Fit the new CPU
Line up the alignment notch or golden triangle on the new CPU with the socket, lower it in without pressing down, and close the retention arm.
6. Apply thermal paste and refit the cooler
Apply a small amount of fresh paste, such as Arctic MX-6, about the size of a pea for most coolers, then refit the cooler and secure it evenly.
7. Boot and verify
Power on and confirm the system posts. Check what CPU do I have in Windows to confirm the new chip is recognized correctly.
Note: if you’re upgrading to a CPU with a different socket entirely, such as moving from AM4 to AM5, you’ll need a new motherboard and likely new RAM too, not just a new chip.
Test the Result
Run a CPU stress test once everything is back together to confirm the new chip is stable before trusting it with real work.
Can You Upgrade a Laptop CPU?
Almost never. Laptop CPUs are soldered directly to the motherboard in the vast majority of modern laptops, which means the chip cannot be removed or swapped. A small number of older or workstation-class laptops used socketed, replaceable CPUs, but this is rare. If a laptop feels slow, upgrading the RAM or storage is usually the only realistic option.

Frequently Asked Questions
Can I upgrade my CPU without changing the motherboard?
Yes, as long as the new CPU uses the same socket as your current motherboard and the board supports it, updating the BIOS first if needed.
Do I need to reinstall Windows after a CPU upgrade?
Usually not. Windows generally handles a CPU swap without issue, though a fresh driver check afterward is a good idea.
Can I upgrade the CPU in my laptop?
Almost never. Laptop CPUs are soldered to the motherboard in nearly all modern laptops and cannot be swapped.
Do I need new thermal paste when upgrading a CPU?
Yes. Removing the cooler breaks the old paste’s contact, so always apply fresh paste before refitting it.
