Ram in A2+B1 equals D. Dual Channel
Ram in A2+B1 equals D. Dual Channel
others are discussing this topic, and it makes sense. The correct setup should be A1 with B1 or A2 with B2 if you mix them, which keeps everything in a single channel. This naming rule often involves color coding to simplify switching to dual channels. By assigning it to A1/B1 or A2/B2, it becomes easier to manage.
A1 and A2 have identical traces on the motherboard, along with B1 and B2. The video is a bit unclear but explains memory layout concepts beginning around 9:30.
The BIOS isn't responsible for setting up configurations—it deals with the actual placement of copper traces on the circuit board. A1 and A2 are both linked to channel A on the CPU, while B1 and B2 connect to channel B. The software doesn't trigger dual-channel functionality; it simply works if both memory channels have relevant components.
