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.

    hp compaq dc5800 small form factor I was wondering if I could upgrade to a i5 quad core

      You apparently have a AMD Processor, so you would need to swap the motherboard, for one that has a socket that will accept the i5 you want.

        These are Intel systems, that normally shipped with a Core 2 Duo CPU, such as an E8400 (3.0GHz), though I upgraded mine to the E8600 for 3.33GHz, fairly much top of the line for the Core 2 Duo (dual core) series.

        While an i5 upgrade is impossible w/out a MB swap (the cost wouldn’t justify the upgrade), there are Core 2 Quad upgrade paths, to include the best of the business/consumer model Q9650 (3.0GHz). The GHz level remains the same, though with a quad core & 4MB more L2 cache, it’ll plow through as much work as some of the i5 series will, especially among the notebook line.

        However, the Q9650 was Intel’s flagship CPU for some time, and it’ll still hold it’s own against some i5 desktop CPU’s of today. Of course one difference between the ‘i’ series line is built in graphics (not desired by all, a dedicated card is far better), though many will prefer having some form of modern graphics. Like if one’s building a PC & wants to install the GPU last. This allows for that option.

        My Dell Optiplex 780 with the Q9650 which by chance am on now is no slouch, hampered only by the lack of SATA-3 ports. While I could had chosen a SATA-3 card over a discrete GPU, that extra speed trade off wasn’t worth it to me to gain the slot for what wouldn’t be a true (as in real life) SATA-3 connection. Would had performed faster than SATA-2, though more on the level of low end cards of the 60-120GB level.

        Keeping in mind that I never had a SSD until 2012, am happy to be where I am.;-)

        I’m working on a upgrade for the dc5800, if not a Q9650, maybe a step or two below, a Q9550 or Q9450 (all has a 12MB cache & runs 1333MHz RAM).

        Kind of hard to be saving for a build & upgrading other computers. Plus Windows 7 64 bit is the upper limit for the HP dc5800, an attempt to upgrade to W10 resulted in BIOS corruption, had to rescue with the BIOS files on a bootable Win98 disk. Kind of odd, I had installed some of the Previews & these ran fine.

        When W7 reaches EOL, will retire as a good Linux Mint PC.;-)

    I have an Asus P5GD1-VM with the 915g chipset. Has anyone had any experience with this setup?

    I have an Ideapad Z510 with i5 -4200 M and I want to upgrade it to i7 – 2600K. My manufacturer only supports i7 4200MQ. What will happen if it still upgrade the cpu? What will be the issues I can face?

    • Ian April 30, 20163:18 pm

      You only have support for what your manufacturer (Lenovo) has in its bios. You need to dump a BIOS upgrade, and see all the processors it supports, and then see if you can find and add the microcode for that…

      Most of the time for laptops, the limit is the amount of power you can deliver based on the power supply on the motherboard.

      The first issue is the hardware configuration, and the ability to reset it back to the factory settings, like it came that way.

      The second issue is the software, and the windows licensing… You get to change two out of 5 before you have to re validate…

      You cannot put a desktop cpu in a mobile socket, it simply will not fit.

    I have a Compaq Presario CQ60 300EV laptop with motherboard 498460-001. I am trying to replace AMD Sempron SI-42 (socket S1) with a better and dual core processor. I have tried 3 models till now and none worked. The last one was AMD Turion 64 X2 TL60 but didn’t worked. What is the best supported cpu type for this laptop (motherboard)? Thank you.

    My MoBo is MSI G41M-P33 combo.

    I have purchased a Xeon X5450 processor (Sspec : SLASB – Stepping : C0 – CPUID : 10676) and put a LGA771>>>LGA775 sticker on it.

    I have also implemented the following micro-codes to the MSI G41M-P33 latest BIOS :

    After I flashed the BIOS, cleared the CMOS (jumper short ***and*** battery removal) and then rebooted the machine … it’s NOW AWFULLY SLOW !

    Taking more than 15min to reboot and windows operations are VERY VERY VERY sluggish.

    I finally had to replace my X5450 with another entry-level X3040 and now it works again just like before …

    Would anyone have any clue/hint how to make the X5450 proc work at “NORMAL SPEED” on this MoBo ?

    Needless to say that this MoBo has already been tested as OK for an X5450 upgrade (as stated here : )

    i have a question;
    will my msi grenade a68hm support an amd fx 8350? (sorry if the question is dumb, not a pc expert)
