    What computer do you have? Which version of the BIOS is installed? What memory do you have in the system? RAM speed is normally limited to what the chipset supports, so at a fixed speed…

    OK, first of all it's a PO5 (Predator Orion), not P05 (Predator Zero), any searches on any Acer site for P05 will fail. :) You do have the latest BIOS version, which fixed the issue with Intel 13th and 14th gen chipsets. Your memory is running at it's normal speed. Do you have the stock memory in it, or have you purchased other memory? Your system does support overclocking when it has all XMP memory where each chip supports the same XMP profile. There is no "Auto" setting for memory overclocking, only fixed speeds depending on the profiles that are available.

    Your PO5-650 should support the following ram se @ Crucial Ram Upgrades for the PO5-650 desktop but you first need to update the bios to its last version R01-B2 that updated > as it updates the INTEL Microcode 0x12B update for the Intel 13th and 14th Generation CPU issue and should also fix ram issues. good luick and hope this helps you further.

    I refer to this thread https://www.reddit.com/r/cs2/comments/16kwxqy/random_mouse_disconnects/

    This answer :

    Fixed my issue thanks to user @KeminoLP - set your ram speed to auto in the bios. i had a manual OC on the memory. xmp also caused the same issue, after setting it to Auto, no more mouse stutter.

    XMP profiles are definitions of what speeds the memory support when switched to XMP overclocking mode. Typically the memory will support multiple options, so 3200, 3600, 4800, etc… As can be seen in Steven's post your model supports overclocking up to 6600, but they don't list which speeds between 4400 and 6600 are correct. For that reason, if you are replacing the memory in it's entirety I would purchase memory that supports XMP at 6600MT/s and then enable XMP in the BIOS. You may or may not have an option to set it to auto. All we can see is what is in the documentation:

    So, enabled or disabled…
