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.

1rx8 vs 2rx8

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. However, if the two sticks have differing capacity, e. If the speeds of the two sticks are different, but the capacity of the sticks are identical, the "faster" stick will run at the speed of the "slower" stick, and it will run in "dual-channel" mode. Thanks Itsmyname, ok but what about two identical sticks but with differing number of ranks? That's my original question!! In your answer you talk about "unequal sticks" and you give for example differing capacities or differing speed, etc So my original question is still "will these 2 sticks run in dual channel mode in my dual-channel compatible 2-RAM-slots Omen 30L?!!! I can't find info about this specific notion in the HP documents, and very rarely in other sources of info, and when I do, they are contradictory

Hi: This link does a good job explaining the difference.

Have you ever wondered what those numbers and letters on your RAM modules mean? They are not just random codes, but they indicate the rank and channel of the memory module. Choosing the right RAM for your system can make a huge difference in performance, reliability, and cost. In this article, we will compare 1rx8 and 2rx8 memory modules, which are like the two sides of a coin. We will look at the pros and cons of each type, and help you decide which one is best for you. They are used in servers and workstations to improve system performance. This allows for eight chips to be installed in the module.

A large number of banks means fewer chips in the memory module , which improves its reliability and power consumption. The main difference between 1Rx8 vs 2Rx8 memory rank is their data block arrangement. The 1Rx8 memory-module has only one data block with 64 bits, whereas 2Rx8 has two data blocks, and each row contains 64 bits. Therefore, the faster memory-module is 2Rx8. Furthermore, single-rank modules are incompatible with the systems that support dual rank and vice versa. The main characteristic of 1Rx8 memory rank is that it has only one RAM that contains 64 bits only. Furthermore, the 1Rx8 memory model has one side empty , but the arrangement of the bits depends on the model of the memory.

Moderators online. Every transfer is 64 bit wide. Latest: John Chesterfield 2 minutes ago. PC3 is standard voltage 1. The limitation seems to be 4GB per rank. R1x8 therefor means this module is a single-rank module, the other module, R2x4 being a dual-rank module.

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.
