I am having issues setting xmp profile with i7-12700k and gigabyte z690UD DDR4.

Memory modules:
https://www.gskill.com/specification/165/184/1620973669/F4-4000C14D-16GVK-Specification

Once in BIOS i set the profile to only available, i guess its automatic which corresponds to the specs on the link, as i7 can go up to 3200MTS, set the memory clock mp to 32…
And the result is no boot black screen, have to reset BIOS.

Am I missing something here?

    Probably got unlucky with the memory controller.

    You do have to remember that officially it only supports upto 3200 on DDR4, yet you are pushing it with a very high end kit of 4000, heck on CL14 too, thats very taxing on the memory controller.

    Honestly, just dial it back down to 3600 or if you are extremely unlucky, back to 3200. To do that, enable XMP, then go to your ram speed section and it should give you a drop down menu, then just select 3200.

    And dont repeat this stupid purchase in the future, 3600CL14 is 1/3 the price of the kit you got.

    Update BIOS to latest, set VCCSA to 1.1v, disable memory fast boot, choose Gear 1, set memory reference frequency to 100:133, then try changing the dram frequency to what you want

    12th gen ddr4 controller is rated for 3200mhz by Intel but unlocked chips can do higher unless you got really unlucky

    I have a 12600kf, I’m using 1.25v system agent, 1.3v vddq, 1.45v dram to get 4000mhz working in Gear 1. I have single rank Micron rev B so it’s not too taxing on the memory controller. Dual rank would be more difficult
