So I went all out on a new build...8700k ... Msi godlike gaming z370 16gb g.skill 4266 ram. .... The xmp settings in the board so not work...overclocking fails. I tried several of the built in settings...all fail. So I contact msi support and get this Dear Customer, please purchase compatible RAM from the link here: https://www.msi.com/Motherboard/support/Z370-GODLIKE-GAMING#support-mem-5 Then go to Product Service Menu on the left and click on Compatibility below. Then click on Memory Support COFFEE LAKE. Thank You. End User 11/15/2017 so the link i was given: https://www.msi.com/Motherboard/support/Z370-GODLIKE-GAMING#support-mem-5 leads to a blank page - i am also not interested in this type of information. i solved my issue myself and got the board to boot by inputting the manual CAS settings that i got from G.Skill. windows now boots and the RAM runs fine at 4133mhz. so thats good. however, when i reboot, the board shows overclocking failed message and i have to enter the bios, load the saved settings and reboot. it seems like a board issue. i'm trying to HELP MSI here...i paid $500 for this board and expected a bit of support. MSI Tech. 11/14/2017 Dear Customer, please refer to the list below for RAM compatibility: https://www.msi.com/Motherboard/support/Z370-GODLIKE-GAMING#support-mem-5 End User 11/14/2017 hello - i have recently built a new system: i7-8700k msi x370 godlike gaming F4-4266C19D-16GTZKW G Skill RAM i have them installed in banks 2 and 4 default boot up they are set at 2133mhz WAY under spec. i enter bios and set XMP profile will not boot - overclocking failed message i use memory try it function and fails i set the pre-set to DDR4-4266, 4000,3600,3200, and 3000 ALL FAIL i manually set the CAS latencies, voltage, and spd and STILL it will not operate at anything OTHER than 2133 mhz. do i need replacement RAM? what is going on here, this stuff was very expensive. Just a fair warning to anyone looking to build something new and buy MSI. you will be on your own completely. You can get it to work but have to do a lot of online research and tinkering.
