  1. Have you updated the BIOS of the ASRock board? Intel isn't as picky as AMD for RAM compatibility, but there's still no guarantee unless the modules have been tested and appear on the QVL.

    1. Check the QVL*
    2. Update the BIOS
    3. Manually enter timings

    *If they're on the QVL, you may need a BIOS update to support them. If they're not on the QVL, a BIOS update may still assist with getting them stable at, or near the rated speeds.

    this is your memory so check spd it could run but your board is not on the support list http://www.galax.com/en/ram/hof-ram/galax-hof-ddr4-3600.html

  7. The memory you have isn't on the QVL:
    https://www.asrock.com/MB/Intel/Z370%20Pro4/index.asp#Memory

    The majority of the kits tested @ 3600MHz use Samsung memory/B-Die, so there's hope..... but you'll likely have to manually enter/loosen timings a little.

    I haven't used a modern ASRock BIOS, so can't really help on "how" specifically. There's an option in your "Overclocking" menu (AI Tweaker for ASUS, probably another name for ASRock) - around where you enabled XMP (I assume) where you can manually enter timings.

    The stock timings for 3600MHz will be printed on the sticker on the modules, or on the retail packaging.
    They;'re also on the "spec" page that scout linked: 17-18-18-38

    They are compatible with at least two other ASRock boards (ASRock Z170 OC Formula & ASRock Z170M OC Formula) so there's definitely some hope. If I were to hazard a guess, you'd likely have success with manual timings and 3200Mhz or 3400Mhz. 3600MHz *may* be a bit of a stretch, but no harm in trying.
