I have two 32G kits 4X8 Corsair Dominator Platinum, one 2400C10 kit and other kit is 3866C18.
Been running the 2400C10 kit since I set up system and used it to get stable overclock, then I shut down, swapped out modules put in the 3866C18 kit I just bought last week, and if I click XMP profile,.. system runs through Q-Codes, stops at Q-Code 09 : PCH initialization after microcode loading, with black screen.
I can push memory OK button, restart into BIOS settings and see the 3866MHz memory, timings, voltage, everything looks good,.. except the vary high VCCIO and System Agent Vcore applied in Auto mode with XMP profile.
When running the 2400MHz kit in XMP profile the VCCIO in AUTO is 1.05V and System Agent is 1.15V,..
