Dual channel or quad setup
Dual channel or quad setup
A memory channel differs from a memory slot. All four slots function, and you can identify the memory. Each channel has two dimms, supporting dual channels.
If you don’t have a quad channel, it might still be worthwhile depending on your needs and budget.
Occasionally it hinges on whether the rank is dual or single. I’m still unclear on the details, so someone more experienced can clarify if needed.
