Optiplex 5050 SFF Processor Compatibility

Hi,

I've recently acquired an Optiplex 5050 SFF that came with a 7th Gen i5.  Is the motherboard compatible with a later i5 CPU such as the i5-9400f?  I'm just wondering if anyone has tried upgrading the CPU in this way and if it worked.

Thanks

    Although it is not on supported list, OptiPlex 5050 met all requirements and can take a straight forward Win 11 installation.  At least up to build version 22H2, but same result is expected with 23H2.

    Set BIOS firmware to UEFI boot mode, enable Secure Boot and TPM.

    Download and make an installation USB media using Windows 11 Creation Tool.  During selection of destination, delete all existing partition to one unallocated space.  Let Windows installation format and setup partitions automatically.  Disconnect ethernet to receive option for local account setup.

    Or you can download Win 11 ISO and using Rufus to select whichever bypass options for unsupported machine and to select local account, no data collection, no OOBE questions.

    "delete all existing partition[s] to one unallocated space"  To add further detail, don't delete partitions labeled "MSR" and "System."

    What is the reason for preservation of partitions that may or may not existed (new drive) in the first place?  Why not allowing the Win 11 installation to create them?

    Windows installation guide from Dell also has the same agreement here, Full Resolution - Windows Reinstallation - YouTube

    "delete all existing partition[s] to one unallocated space" speaks of a used drive with an OS already on it.  Of course Win11 will make all the necessary partitions on a "new drive," which is referenced in your post above.

    While Win11 might be different, Win10 didn't allow me to delete "system" and "MSR" partitions when reloading.

    Sorry to hear that it didn't work for you.  Although my post was to provide instructions for user PW93 inquiry to install Win 11, the video posted by Dell-Nat M having the same instructions for Win 10 installation.

    The main point is to prep the drive for installation, used drive needed to be reset to work as new drive.  Nothing left behind from previous OS.  Hence the meaning of a clean install.

    "System" isn't referring to the OS.  I've done clean installs just fine.

    I think this discussion is going to some sort of stalemate, so please never mind that I said anything.

    @Smokey2021​ 

    No.  An AMD CPU will not fit in an Intel socket.

    Ebay is probably one of the best and easiest places to get a new MB.

    When replacing the battery, remember to only press on the release tab with a small screwdriver and the battery will come loose.  No prying.
