I checked and don't have a BIOS setting for FCLK. I looked at DRAM calculator difference between SAFE and FAST and the only difference I see is Misc-Gear-Down-Mode enabled. So I tried that and it would not boot.

I am wondering if this motherboard (GIGABYTE B550I AORUS Pro AX) is too new for the DRAM Calculator? When you use the Motherboard pulldown-selector it does not list B550 (see image below). So I chose the next best motherboard = X570.

I have run out of memory settings to try!!

[USER=2477]@Instran0[/USER] - Yes, I am using VLP-RAM is because of the low clearance with the Black Ridge cooler and 100mm fan mounted underneath the cooling fins. But it might be best to discuss other cooling options here-on-my-build-advice-thread. If I can't get memory speed higher than stock 2666 MHz I will probably change to a different CPU cooler, but more likely it will be the old standard Noctua NH-L9a-AM4 low profile CPU cooler. I don't want a CPU cooler sticking out the side of my case.
