    I am really sorry for the confusion. I added my System Two on My Computers. Please refer below.
    Yeah, I re-read your first post and it does state an EX-H310M-V3 R2.0 (Intel board). My mistake. I'm use to looking at system specs. See my edited reply. Apologies.

    Your problem

    That's all that your Intel CPU supports.

    Mike that's just Intel's RAM spec, it has nothing to do with what the actual RAM speed can run at. Example: My Intel i9-9900K list shows DDR4-2666....

    but my Gigabyte Z390 Aorus Xtreme board supports speeds up to 4200MHZ. I'm currently Corsair's 3600MHz modules and that's what XMP has them set at....

    Point? The OP's board does support (states) 2600MHz modules.

    and Ram supports 3600MHz speeds....
    That's different, those G processors are quite limited. My Ryzen also says 3200 but I had it at 4000MHz.

    I'm going to amend my post to say you "could" be right about the "G" processor. I just know the OP's manual clearly states the board supports 2600MHz RAM, and Intel also supports XMP modules.

    That said, I see nothing in the manual to indicate how to set XMP so I can only guess it would be "auto" set if it was supported. However, still confusing is CPU-Z saying 2600MHz (1333) as well

    I have never owned a motherboard that used the XMP memory settings by default. I've always had to turn that on in the BIOS settings.

    I'd expect the setting to be in the Main screen in the BIOS. The OP doesn't provide that among the pictures (post 11). It may be that the XMP support isn't really there. It certainly looks like the board isn't an overclocker's dream.

    Same here.... but and what of those "store bought" prebuilt desktop PC's?

    But yes, on every motherboard I bought supporting XMP, I had to enable it in the BIOS.

    True, but going through the manual I see no setting for XMP. And there's no mention of it either.

    Most BIOSes use JEDEC as default (this RAM of mine uses 2400). There's also 2 XMP profiles, 3000 and 3600. This is also a bit weird BIOS, it doesn't follow XMP to a letter but at 2400 and XMP (Asus calls it DOCP on Ryzen) it sets lover Cl by 1.
    After screwing with RAM settings for a while I found that I can set DOCP at 3000 and memory frequency at 3600MHz and that results in simple but effective lower Cl than XMP says it should be. Couple of changed settings later it gets as good performance as it can. I guess that having Samsung b-die chips helps too. As you can see, BIOS and XMP don't have to have same values.
