2rx8什麼意思

"2rx8" is a term often used in the context of computer hardware, specifically referring to memory modules. Here's what it means:

• "2r" stands for "2 ranks." A rank is a set of memory chips that can be accessed simultaneously. Dual-rank modules have two sets of memory chips that can be accessed independently, which can improve memory performance in certain situations.
• "x8" refers to the data path width, which is 8 bits. This means that each memory chip on the module can transfer 8 bits of data per cycle.

So, "2rx8" describes a memory module that has two ranks and an 8-bit data path width. This is a common configuration for DDR3 and DDR4 memory modules used in personal computers.
