2rx8意思
"2rx8" is a term commonly used in the context of computer hardware, specifically referring to RAM (Random Access Memory). It stands for "2 ranks, dual channel, 8 chips per side."
Here's what each part of the term means:
-
2 ranks: This refers to the number of memory modules that can be accessed simultaneously. A rank is a set of memory chips that are accessed as a unit, and having two ranks means that the memory controller can read from or write to two different sets of chips at the same time, which can improve performance.
-
dual channel: This is a technology that allows the computer to access memory using two 64-bit channels, essentially doubling the memory bandwidth compared to a single-channel configuration. Dual-channel operation requires that the memory modules be installed in pairs, with one module in each of the two channels.
-
8 chips per side: This indicates the number of memory chips on each side of the RAM module. Each chip contains a certain amount of memory, and having more chips generally means that the module can store more data.
Putting it all together, "2rx8" describes a type of RAM module that has two ranks of memory chips, is designed to operate in a dual-channel configuration, and has 8 chips on each side of the module. This configuration is often used in desktop computers to provide a good balance of cost and performance.
