I am only asking as I was under the impression that the same colour was to be used and some school machines I have here have the two sticks in different coloured slots. The machines were brought to me for tidying up -clogged with dust etc and they have been struggling all day with the boot and going from app to app.
So I threw in two sticks into the empty slots from one of the other machines and noticed an immediate difference. Would this be due purely to more RAM or that the slots are now configured correctly or both?
In my experience, the same color indicates the same RAM channel, but I am not sure that is universal across all brands.
So--installing to slots of the same color would allow the RAM to run in the preferred dual channel mode.
If you have a 4 slot board and two sticks were installed to different colored slots, the RAM would work, but would not be running in dual channel mode. But if you then installed 2 more sticks in the remaining 2 slots, you would then be in dual channel because each colored pair would then be fully occupied.
The improvement you see would be mostly due to simply having more RAM, rather than the change from single channel to dual channel.
At least that's how I think it works. But as I said, I'm not sure how universal that color-coding is.
