Switched to XMP profile for ram

Then razer blade 2020 advanced won’t boot up to login screen. Obviously power there as keyboard and lights come on. Recently installed crucial ballistix 64gb of 3200 ram saw it running at 2900, not the published 3200, changed bios to use xmp profile, f4 to save and exit. All seemed good. Trying to boot up now. Nothing past the keyboard lighting up. Anyone know what to do next?
