    Same issue here, P03-640 running R01-B0 BIOS and XMP is greyed out -- no ability to enable/disable, even after setting a supervisor password. RAM installed is XMP compatible etc. Baffling, and frustrating!

    yeah, i have the same issues on a 5000 series PO5-640-UB11 with its newest bios update R01-A4 no solid answers as to why either.

    I'm sure Acer staff have access to these forums so hopefully take the feedback into account and release bios updates to enable XMP profiles, because until then there's currently no solution to the issue.

    Yanno i have to be honest with you after watching about a dozen YouTube videos and reading many articles about it all from different gamers and people in the business it's basically BS Ya only get about 5-10 fps increase and it isn't good to overclock things, they say people are so consumed with over clocking they overlook the basics to improve their pc like what you did NeoGeo it's a perfect example. look at that score and nothing on your computer is over clocked right?

    Essentially XMP isn't exactly overclocking though, it enables the RAM to run at the manufacturer's intended frequency via preset and tested profiles that should not do any damage as a result.

    At this point it's as much principle too at this point, XMP is supported and *should be working* on these machines but isn't for whatever reason -- Acer could and should be doing more to acknowledge this is a problem and push out a fix? Instead, I've paid for RAM that is capable of almost 1GHz additional frequency and my XMP-capable mobo doesn't want to play ball, I'm stuck with RAM running at a significantly lower frequency.

    Yea that's just stock settings on benchmark, i actually tried an overclocked and got a much higher score but overclocking adds extra heat on components and can affect the lifespan too, something to bear in mind.

    I was raising this discussion. I think twelfth gen processors support xmp 3.0 with ddr5. The problem is that the po3-640 motherboard only supports ddr4. Perhaps, this is the reason why xmp profiles are not activated in the bios.

    Hi @egydiocoelho ,

    The thing is , i have a PO7-640 12th gen and some members have PO5-640 12th gens both with ddr5 and xmp isn't working on these either leading me to believe it's a bios issue.

    well from what i have seen-heard in YouTube videos and read it is overclocking and they even call it overclocking because i bought crucial ddr 4800 MHz and with XMP enabled on a MB that allows XMP you get 5200 MHz and Acer limits us to 4400 MHz no matter what we use for whatever reason they decided this. if I'm wrong i stand corrected but i know what i have read and heard. and if Acer did not limit us to 4400 MHZ whatever ram we put in would run at the advertised MHZ no matter what without XMP enabled.


    a few examples:


    “Overclocking is not something that is covered under your warranty. So if you damage a part due to extreme overclocking or something, that’s not covered,” an Intel official confirmed to PCWorld during the Rocket Lake press briefing. The official further confirmed, “XMP is classified as overclocking, so memory overclocking would fall under that same umbrella.”


    Intel XMP is an automated overclocking technology that enables motherboards to configure memory settings above and beyond the basic rated speeds of the PC industry, which are often significantly slower than the speeds that are actually achievable with a few clicks and compatible hardware.

    Thanks for raising this, hopefully, we can get clarification. Appreciate all the help and advice thus far :)

    On a whim I bought a Kingston Fury DDR4 kit just in case the Crucial Vengeance kit was somehow causing upset, same result re: XMP greyed out in the advanced BIOS menu.

    I guess (reading back my post it's clear that Forums before Coffee is a bad idea) what I was getting at is XMP versus traditional overclocking (i.e. CPU, GPU overclocking) are a different kettle of fish entirely. XMP is viewed as far safer generally speaking.

    I'll copy and paste a colleague @Kno63 answer:

    Maybe the 12.th generation processors only support XMP 3.0 with DDR5 memory:

    https://www.intel.de/content/www/de/de/gaming/xmp-3-for-core-processors.html

    XMP 2.0 seems to be for 11.th gen processors with DDR4 RAM:

    https://www.intel.de/content/www/de/de/gaming/xmp-for-core-processors.html


    The user has DDR4 RAM, but 12.th gen processor:


    The mainboard seems not to be able to support DDR5 RAM. Service guide:

    Just as an idea! ;-)

    @egydiocoelho Hi Pal, i'm on a 12th gen i9 12900k, with ddr5 , using xmp 3.0 ram but still no xmp option as its greyed out

    In the same boat as everyone else with memory upgrade questions. I've read in another thread that ThisGuy got 32gb Corsair Vengance DDR5 running with XMP enabled at 5200 Mhz - but this is the only time I've read about XMP actually working...

    What I'm wondering is why XMP is even included in the bios if ACER is so set on slowing their "Gaming PCs" down from even the bare minimum that is the offical Intel supported standard.

    well i do know now that what he is experiencing alot of users are with 4 sticks of ddr 5 memory and XMP enabled if he shut off xmp i bet his game would not crash there are videos all over youtube detailing this issue and it really hasnt been fixed yet properly many have found ways around it by undervolting the CPU etc. and im not 100% sure but its not only acer, dell and hp that do this any big name brand manufacturer limits you. its called pre-built proprietary components OEM vs pre-built SI-system integraters-cyberpower-ibuypower-skytech the list goes on and on but you get the idea, ive been doing research and its crazy how they limit us compared to the SI built gaming rigs. i never knew until just recently about this but i had a Cyberpower and a HP Omen 40L both got returned for the Acer Predator 5000 i currently own now. so im still researching it all to learn more, most probably know about this its just all new to me. and who knows maybe the cyberpower i had was a killer rig and i didnt know anything i had just got into gaming and bought it then returned it 30 days later for the HP Omen and after 30 days returned that for the Acer haha. no going back now only forward.

    i got this from a web site-v

    Prebuilt computers are often sold on the strength of major components such as the CPU and GPU. However, other components can have a major impact on both the performance and longevity of your computer. A good prebuilt PC should have details of the exact model for every component available. If the builder doesn’t disclose the brand and model of the power supply, motherboard, RAM, and other components, that’s a red flag.

    Many prebuilt systems use unbranded OEM (Original equipment manufacturer) components in order to cut down on costs. These are not necessarily poor quality simply because they are OEM components, but it’s a good idea to find out whether the no-name PSU or SSD in your prebuilt computer was built by someone with a good reputation.

    We are talking about a PO3-640 here, it doesn't use DDR5, it uses DDR4.

    You should do that in the appropriate thread, it will just confuse people to have DDR5 info on this thread…
