Mixing ram capacity
The information is clear from the manual. Channel A includes Slot A1 and Slot A2, while Channel B features Slot B1 and Slot B2. If your statement holds, placing two sticks in A2 and B2 wouldn't allow dual-channel use since both sticks would target the same channel.
again it's more confusion over what is a "channel" and a "bank" actually the manual is technically incorrect in the terminology being used. what it calls "channels" are technically "banks" as in a discrete group of ram slots. A Channel is the actual BUS between the RAM and the CPU. Now the terminology has shifted a bit with the term "channels" often being used interchangeably for both
When A2 and B2 share the same channel, you can achieve dual-channel functionality by configuring the system to utilize both channels simultaneously.
again, your confusion is understandable. technically, what people refer to as "channels" are actually "banks," which correspond to the grouped RAM slots—Group A and Group B. The channels serve as the bus interface connecting memory to the CPU. That’s why dual channel operation requires RAM in each bank (A-B) across the relevant channels; for example, slots A2 and B2 both belong to a "bank," while slots A1 and B1 form a single "channel." As discussed earlier, the mix-up likely comes from using the terms interchangeably, with "bank" being less commonly referenced.
It's named "dual-channel" because both channels are used, even though they're placed in the same one. The term reflects that there are two active paths or signals being managed together.
I'm still trying to wrap my head around this, but it seems like you're using old-school ideas to describe modern tech. A "bank" could mean a set of RAM slots grouped together, so A1 & B1 or A2 & B2 might fit that definition. In fact, historically, RAM was organized in banks, and you'd need to fill one before moving to the next. A bank could range from just one to eight slots. The dual-CPU 486 board I mentioned had eight slots spread across four banks of two slots each.
