Hello all. Again going up this thread, because of lack actions from Gigabyte team. I was contacting Gigabyte support again for check if there is BIOS or some kind of fix for that. And after 2 months (almost) waiting for reply (there is still open ticket, where they saying - sending this to technical team, wait for reply) i decided to contact them again. Now they told me, it's not BIOS related or triggered by BIOS (really gigabyte? look on other topic with Z270X-Gaming 7 - SAME PROBLEM like on this my board Z270-HD3P) and they recommends me to try : 1) one stick ram in each slot, 2) change voltage for RAM to 1.4v, 3) try to other RAM sticks. Well, i tried points 1 and 2, with no luck. This problem is really need to be fixed asap. This issue is PITA and i am waiting for BIOS (like others for their boards) too much long. And i am not alone, who thinks (not only in my case with this board) thats a problem with compatibility of RAM (Corsair especially) with Gigabyte motherboards (also with this mine model - Z270-HD3P). I am gonna give it last chance, otherwise... I am gonna buy motherboard from other brand, if there is no solution for that.
