    Some BIOS options are locked because they don't wish for you to mess with settings like XMP or overclocking. Nothing you can do.

    Quick update from my side, regarding the PO3-640, the most recent BIOS update from Acer (R01-B1) allows XMP to be enabled within the BIOS. Since enabling this earlier in the year I've not experienced any issues whatsoever, and I did see a small performance boost per benchmarking and my own anecdotal before and after testing. Props to Acer for adding the enable XMP option at a later date!

    You'll want to check your product support page, for me (PO3-640) was this was here and grab the relevant update package. The download archive contained a PDF with instructions to follow, and it is strongly advised to proceed with caution re: BIOS updates as things can go rather wrong if you're not very careful.

  • I advise disabling the antivirus and connecting the computer to a sinusoidal UPS. This will prevent power outages during the update.

    all you guys need to remember that every acer desktop comes with non XMP memory. that's why it won't turn on. get some XMP ready memory and it will work then. i have a newer 5000 series and I'm using Corsair Dominator Platinum 2x16-DDR5@6200 and it works flawless, and it is way faster than the 4800 i had in there from crucial.

    While that will be the case for some, that is not applicable in this instance (and many others documented here). I upgraded my RAM and XMP was not enabled in the BIOS by default, it needed to be manually enabled - the kicker being that it couldn't be enabled as the BIOS didn't allow it to be enabled. Flash forward 6 months or so and Acer did the right thing (thank you Acer!) and released a BIOS update that enabled the enable option, I went into the BIOS and enabled XMP and bam XMP works (and is completely stable, with a nice little performance boost per benchmarks and my own anecdotal testing/use).

    yeah, that's the same thing i went through also i got XMP crucial memory and it still ran at 4400 for 2 sticks and 4000 for 4 sticks until i also got the BIOS firmware update to unlock the XMP option in my BIOS. sorry for any misunderstanding but mine wasn't enabled by default i had to get the update then enable it also.

    That is only for the PO3-640 and the link isn't guarantied to stay active. Much better to just download it from your relevant support site.
