It's Kingston DDR4-2666 (8x4) and I was just trying to run as is. I'm in the Philippines and limited in what I could get my hands on. No boot with 4 slots filled. I could only boot with 2 slots filled. I had to do 2 things. I set the RAM to 2400 and I ran CPUZ, took down the timings from the SPD tab and then set the lowest common manually in the BIOS. I'm now able to boot normally most of the time and the system is solid. Occasionally the system won't POST, but a restart solves that. Motherboard is TUF B450M-PLUS gaming.
