Hello all. I am on my second ROG Maximus Z690 Extreme mother board. A service tech from ASUS and I concluded the first motherboard was bad. So, I boxed it up and sent it back. I ordered a brand new one, did my build, and the same dang Q code of 55. I have confirmed with a tech from ASUS that all my parts are compatible.
Power Supply = Corsair RM Series, RM850, 850 Watt, 80+ Gold Certified full modular power supply
CPU Fan = Vetroo Eclipse Low-Profile ARGB CPU Cooler, 90mm 4-Pin PWM Fan
I have tried with one memory stick and 2 memory sticks, I have pulled the CMOS, and I have tried (with an ASUS tech on the phone) to flash the bios. I have checked my CPU pins, and all appear fine, and I have made sure my CPU fan is not on too tight.
