Problem with PC not booting after adding new RAM.
Additionally, be aware that your PC might run slower because it will operate in dual channel mode while only using single channel more often. Once you surpass the 2 stick pair with 8GB of RAM, the system will switch to single channel speed. You might notice a drop in performance when it goes beyond that point. For example, if you have two 4GB sticks and one additional 4GB stick, once the total reaches 9GB, the other stick will start using its single channel bandwidth.
the original pair should operate in slots 2 and 4, which will function within the duel channel. there is a pair that works on the same channel, and slots 1 and 3 serve different bandwidth channels. when one slot becomes active, it limits the available bandwidth to half of that channel's capacity. as discussed before, once the pair in slots 2 and 4 is exhausted, it will switch to a single channel RAM. this transition leads to a drop in performance rather than an improvement. the reason is that RAM operates more slowly on a single channel. although there might be minor advantages like increased stability, the overall speed will decrease. for instance, you may avoid stuttering but could experience a lower frame rate, or vice versa if input lag occurs during lane switching.
for example, a system with four slots in each direction outperforms one with eight slots in two directions mainly due to the greater bandwidth capacity.
