One of the most common questions asked by those new to PC building is "what CPU will my motherboard support?" This page serves as a quick reference guide to answer that question. Note that this list does not include all specific models, only main socket types and most boards. 

WHAT IS A CPU SOCKET?

A socket is a part of your motherboard that holds the physical CPU in place. When you perform a CPU upgrade, typically you would remove your old processor and replace it with a new one. This requires you to remove the old CPU from the socket (which is very likely soldered) and fit in a new one. The CPU socket on the motherboard dictates what kind of processor you can fit into it.

WHAT DOES ATX MEAN?

ATX is simply an industry-standard form factor for the case and motherboard. It originated back in 1995 as a replacement for an even earlier standard which was known as AT (Advanced Technology). The original AT motherboards had mounting hole positions that were unsuitable for mounting into a computer case, so they would instead protrude through the rear of the case where they could be accessed by screws from inside the computer case.

This list is updated as new information becomes available, but you may also want to check our socket-specific sub-pages for more information on CPUs that are compatible with your motherboard.

 

Also, note that some boards support overclocking while others do not - if you plan on overclocking be sure your board supports it before buying a CPU or RAM kit.

 

All motherboards with Intel chipsets will support either DDR3L or DDR4 memory depending on socket type, so only the main Socket specifications are listed below. If your board has an Intel chipset and its official specification sheet does not state which types of memory it supports please contact the motherboard manufacturer for further clarification.

 

Socket 3647

 

All motherboards with Intel chipsets will support either DDR3L or DDR4 memory depending on socket type, so only the main Socket specifications are listed below. If your board has an Intel chipset and its official specification sheet does not state which types of memory it supports please contact the motherboard manufacturer for further clarification.

Debian 8 (Jessie) and newer: Debian 9 (Stretch): All motherboards with Intel chipsets will support either DDR3L or DDR4 memory depending on socket type, so only the main Socket specifications are listed below. If your board has an Intel chipset and its official specification sheet does not state which types of memory it supports please contact the motherboard manufacturer for further clarification.

Ubuntu 14.04 LTS and newer:

 

Debian 7 (Wheezy) and older: Ubuntu 12.04 LTS and older:

All motherboards with Intel chipsets will support either DDR3L or DDR4 memory depending on socket type, so only the main Socket specifications are listed below. If your board has an Intel chipset and its official specification sheet does not state which types of memory it supports please contact the motherboard manufacturer for further clarification.

 

AMD motherboards are not supported by any Socket 1151 CPUs, and no AM4-compatible Ryzen CPUs have been announced at this time.

Important things to watch out for:

  • Always update the latest BIOS for your motherboard before upgrading the CPU.
  • Some motherboards don't support all processor generations.
  • Some motherboards have multiple revisions, and they may not be compatible with the same processors.
  • You'll need to know if your computer is prebuilt or custom-built, as well as whether it uses a different motherboard (depending on the components supplied). You may not be able to use the same processors on a prebuilt system because the motherboards are incompatible.




Only motherboards with a matching socket type may be able to use a processor. For example, an LGA 1151 motherboard will not support an LGA 1150 or 1155 processor.

If your board supports overclocking you'll need a K-series 'unlocked' CPU.

Some newer boards with UEFI BIOS require special memory. Contact your board manufacturer to confirm compatibility before upgrading the RAM. Incompatible Memory - In general, DDR3L is backward compatible with most platforms that support DDR3 but certain motherboards only support specific memory speeds and may require different kinds of RAM based on generation (DDR3/DDR4) or dual-channel vs quad-channel configuration. As a result, we recommend checking with the board's manufacturer to ensure that the desired modules are supported. Important Note: Always update the latest BIOS for your motherboard before upgrading the memory.

Check if your motherboard has a CPU support list

Make sure you have enough power connectors that are rated for the number of watts required by your processor. Generally, 1 or 2 x 6-pin PEG connectors are needed for Kaby Lake CPUs but boards can vary so check with your motherboard manufacturer before upgrading.

Some motherboard manufacturers may require you to update the BIOS before supporting Kaby Lake processors.

Make sure you have compatible memory - visit your board manufacturer's website for more information.

Socket AM4 CPUs are not supported by motherboards with an LGA 1151 socket. Be aware that some boards support overclocking while others do not (and cannot without special firmware). Also check if your board requires a certain kind of DDR4 memory based on the chipset, generation, or dual-channel vs quad-channel configuration.
