Recently upgraded my PC, i have 3x 4GB DDR4 Kingston sticks (all same specs). All worked on my previous CPU and showed 12GB in WIndowsNow that i put in the new CPU it is not booting if i put the 3rd stick leaving me with only 8GB, it will only boot with 2 sticks.Any idea? ThanksI tried 1 by 1 and different slots, reseating etc no luck.
