I have gone through your post and would like to help. Hope that answers your question and you have a great day! Have a great day! Yes, the memory-controller circuits on the motherboard are capable of using the "dual-channel" architecture, as well as operating two "unequal" sticks of RAM in "single-channel" mode. If you use two sticks of RAM that fulfill the requirements of operating in "dual-channel" mode, then dual-channel mode will be used.

Connect and share knowledge within a single location that is structured and easy to search. Rank is a data block which is 64 bits wide without Error Correction Code ECC created using some, or all of the memory chips on a module. The x8 in them specifies the number of banks in the memory module. Higher the number of banks, the fewer the chips in the memory module, the better the reliability and power consumption. Compatibility is generally not an issue in most cases. But you should go through the motherboard manufacturer's guide of supported RAM modules just to make sure if they are compatible or not.

Connect and share knowledge within a single location that is structured and easy to search. Either of those modules should be compatible with your laptop. Dual-channel RAM should be added in identical pairs, so I can't be certain whether they are compatible with each other. It's not an optimal combination, so the performance might not be as good as with identical modules, but they should work. I'd just stick them in and test - if they aren't compatible, the system just won't boot properly.

The concept of memory rank applies to all memory module form factors, though in general it tends to matter primarily on server platforms, due to the larger amounts of memory they manage. A memory rank is a block or area of data that is created using some, or all, of the memory chips on a module. A rank is a data block that is 64 bits wide. On systems that support Error Correction Code ECC an additional 8 bits are added, which makes the data block 72 bits wide. Depending on how a memory module is engineered, it may have one, two, or four blocks of bit wide data areas or bit wide in the case of ECC modules. This is referred to as single-rank, dual-rank, and quad-rank. Crucial denotes this on the module label as 1Rx4, or 2Rx4, 2Rx8, or similar. The x4 and x8 refer to the number of banks on the memory component or chip. It is this number, not the number of individual memory chips on a PCB, that determines the rank of the finished module. In other words, if a module has chips on both sides of the PCB, which makes it dual-sided, it can still be single-ranked, dual-ranked, or quad-ranked, depending on how those chips are engineered.
