1Rx8 means it is a single-rank module and 2Rx8 means it is a dual-rank module module. 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.
Can you replace 1Rx8 with 2Rx8?
Generally you can mix 1Rx8 and 2Rx8, as well, though mixing different kinds of RAM sometimes prevents interleaving (i.e., it might be a tad slower). I do recommend running a memory test after RAM upgrades, though.
Which RAM is better 1Rx8 or 1Rx16?
The 1Rx16 modules have significantly lower bandwidth compared to the 1Rx8 variants. The more bank groups a memory module has, the higher the bandwidth is. Contrary to what the naming convention may suggest, the single rank x8 modules have twice as many bank groups compared to the single rank x16 variants.2021-06-29
What is the difference between 1Rx8 and 2Rx8 RAM?
Distinguished. 1Rx8 has the memory on one side only. 2Rx8 is a two-sided memory stick.2010-06-20

What is 1Rx8 1Rx16?
Hi: The difference is the memory density. 1Rx16 is lower density memory than 1Rx8. 1Rx16 memory is very hard to find, and since the 8 GB chip is 1Rx8 and you want to add another one, that is what you should look for. Here is the crucial memory report which has compatible memory for your notebook.2019-12-29
