Question about Acer Nitro N50-656 BIOS Update version 1.04 and Intel microcode patch

Regarding the Intel microcode patch for 13th and 14th generation Intel desktop CPUs, the following article shows that the new BIOS version 1.04 was to be released for the Acer Nitro N50-656 on 10/4/2024.

https://community.acer.com/en/kb/articles/17446-two-year-extended-warranty-on-13th-and-14th-generation-intel-core-desktop-cpus?utm_source=community-search&utm_medium=organic-search&utm_term=intel+13th+and+14th+generation+issue

In the BIOS update section for the N50-656 the latest version 1.04 is indeed listed but the description is "Update Usb module change to v31." Since there is no mention of the Intel microcode patch in the description, I am wondering if this BIOS version does in fact have the new microcode. And if so, is it the microcode version 0x129 or the latest version 0x12B?

I also have a question about the BIOS update procedure, which is in the Appendix folder of the extracted download. Section 1.2 says "Copy "UCP" folders including files to a storage device". Well there is no UCP folder, only the executable file and the ROM folder. Can I just skip this step and run the executable directly from Windows without copying anything to usb?

    The Nitro N50-650 desktop and your Nitro N50-656 desktop have different bios chips and different bios programs DO NOT flash your N50-656 desktop with the N50-650 bios version R01-A4 9/25/2024 that Acer lists in the "Two Year Extended Warranty on 13th and 14th Generation Intel Core Desktop CPUs" article as it will not work as these two Nitro desktops are different.

    With your N50-656 bios version 1.04 bios flash,. right click the application file and then do exactly as the PDF guide says > right click and Run as administrator > Choose “YES” to execute > then allow the executable file to flash the bios flash and go through its shown steps like it shows in the PDF guide, DO NOT interrupt the bios flash until it 100% finishes and the desktop reboots automatically to the OS otherwise you will interrupt the bios flash and brick the bios chip and the desktop will not boot, so be careful, its a very simple process.

    Thanks for you help @StevenGen

    I was able to successfully update the BIOS to version 1.04 without bricking. There were a couple of deviations:

    1. Immediately after running the application file as administrator, Windows Defender interrupted and I had to click on "More info" and then "Run Anyway" to continue.
    2. After the BIOS finished flashing (took about 5 minutes) and the computer restarted automatically, I got the message "Setup settings error. CMOS checksum error or CMOS battery loss occurs. / Default settings loaded. / Press <F1> to Continue. / Press <Del> to Enter BIOS Setup Menu". I pressed F1 and then Windows loaded normally. I never changed any of the BIOS settings, but I guess if I had done so they would have been reverted to their defaults.

    After the update, I used HWiNFO64 to check the microcode version and unfortunately it is version 0x123, so this BIOS version does not include the Intel microcode patches that address the 13th and 14th gen CPU instability issue. I guess we will have to wait for a future BIOS update to resolve those issues which are in Intel microcode version 0x129 and most recently 0x12B.
