1You are confusing speed with capacity. Also, you are confusing 'b' (bits) with 'B' (bytes).– ChrisInEdmontonCommented Mar 8, 2016 at 1:42

@ChrisInEdmonton So the 32gb is to indicate how much information can be held at any given time, and the 21gb is to indicate how much information can be transferred per-second? Where am I confusing bits with Bytes?– airkeyahguhCommented Mar 8, 2016 at 1:45

@Ramhound so does this mean that the motherboard would need a minimum throughput of 21gb p/second?– airkeyahguhCommented Mar 8, 2016 at 3:47

Or rather the expansion slot– airkeyahguhCommented Mar 8, 2016 at 3:49

Minimum ratings aren't useful, because your computer will have very little going most of the time. Your memory controller should have a maximum bandwidth that is greater than or equal to your memory's maximum rating. It's not the end of the world if your RAM is faster than your motherboard, because your RAM will be happy to serve up bits just as slowly as your motherboard asks for them. You'll just be leaving potential performance on the table, that's all.– picobitCommented Mar 8, 2016 at 4:03

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. windows-7), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
