During my new build I installed a single ram chip to prevent any issues during updates and installations. Then after updating UEFI, installing Windows, and updating all drivers and software, I went to install the remaining 7 ram chips in sequential order and came across what I though was a dead slot on the MB (4F q code- pch memory initialization)... So I began standard troubleshooting with pop-swapping chips to ensure it wasn't a dead chip and confirmed it was the D1 slot. I then pulled the CPU to inspect the pins and reseat it. Afterwards started over on the sequential testing of slots and chips and came across the B2 slot and found it was dead BUT the D1 is now working. I've done this 3 other times and each time a different slot is dead and the others would be working... So any clues what may be causing this cuz my head is hurting from scratching it so much. I'm hoping it's not the MB and just the CPU or a setting I can change.
