How to Check if Your Motherboard Supports a Processor



In this guide, we'll go over a few methods for determining if your motherboard supports a specific processor.

Note for those installing LGA 771 Xeons into an LGA 775 motherboard

This guide will only help you figure out what LGA 775 processors are compatible with your motherboard. Once you know this, you can use the information in the LGA 771 to 775 motherboard compatibility guide to figure out what similar LGA 771 Xeons are compatible with your motherboard.

Things you'll need

  • The CPU model number and stepping (how to get the stepping)
  • Your motherboard model number (and revision if it has one). This should be printed on the motherboard, or you can get it through software with CPU-Z (this info should be in the Mainboard tab).

Important things to watch out for

  • You should always install the latest BIOS for your motherboard before attempting a CPU upgrade.
  • Some motherboards don't support all steppings of a processor.
  • Some motherboards have multiple revisions, and they may not support the same processors.
  • Prebuilt computers (like Dell) sometimes use different motherboards (depending on what parts come with the system), and the motherboards may not support the same processors, so you'll need to figure out which motherboard you have.

Method 1 - Check if your motherboard has a CPU support list

The best way to determine if a processor is supported is to check if your motherboard manufacturer maintains a cpu support list. The cpu support list will tell which processor model numbers (and steppings) are supported by each bios version.

For example, if you have an ASUS P5K motherboard, you can find the cpu support list by searching google for: "asus p5k cpu support". This list is also usually linked to from the support/drivers page for your motherboard.

If your can't find the official cpu support list, try searching for your motherboard's model number on They maintain a processor support list for many motherboards.

Method 2 - Search for others with your motherboard that are also using the processor

Note: This method isn't guaranteed to work unless you also verify their motherboard revision and CPU stepping is identical to yours, but it will probably work in most cases.

Try searching for your motherboard's model number and the model number of the processor you want to install. It's also probably a good idea to include your motherboard revision and CPU stepping in the search. This will often turn up other people that installed this processor on your motherboard, and you may be able to tell if they were successful or not.

    If I look at other motherboard with a similar chipset it looks like its not supported.

    Abit IL9 Pro 945P / ICH7 1066 ≥ 65 E6700 (see notes) May not be compatible with this MOD.

    Gigabyte ga-945gcm-s2l 945GC / ICH7 1066 Only supports older Core 2 Duos (no quad core) May not be compatible with this MOD.

    MSI 945P Neo5 Only supports older 65nm core 2 duo. May not be compatible with this MOD.

    Looks like you can add Asrock 945GCM-S board v1 and Xeon 5460 as tested and NOT working.

    I have a GA-G31M-ES2L mobo with a xeon e5440 e0 stepping but this runs on 2.5 instead of 2.85 that this cpu works. Any ideas what has gone wrong i have flashed modded bios

    Hello, I have a Pegatron IPMEL-AE Evans-GL6 motherboard (G41 Express chipset) with an intel Pentium E5300. I’m planning to upgrade to a Xeon E5440 wich have C0 and E0 stepping options. The thing is, my actual processor is R0 stepping, so, do they need to be the same stepping? THX.

    anyone tested “Asus p5b-e plus” and witch the best config for this??
    2nd : i need to know about HP Compaq 6000 Pro SFF with chipset Intel Q43 Express if it’s upgradble with xenon cpu. thanks

    tenho uma POS PQ45AU rev:1.07 da positivo chipset Q45/43 ela segura um quad Q9650 sera que segura um xeon da serie 5xxx ? achei xeons por preços bons e quero acertar na compra sem ter medo de chegar e a placa nao funciona.
    sobre a BIOS da minha mobo nao acho em lugar nenhum mesmo, oque acho é pessoas procurando tben , se caso eu precisar atualiza estarei ferado :(
