Hi Everyone,
I currently have 8gb RAM installed as follows:
Riser A: (Top)
2gb in Dim Slot 1
2gb in Dim Slot 2
Riser B: (Bottom)
2gb in Dim Slot 1
2gb in Dim Slot 2
My question is I've ordered an 8gb kit (2 x 4gb) and I'm not sure in which riser/s I should put them so could someone please advise?
Thanks
David

Mac Pro (Mid 2012 and earlier): How to remove or install memory - Apple Support
| If you have | Install |
| Two DIMMs (standard configuration) | One on the top memory card and one on the bottom card |
| Four DIMMs | One pair on the top memory card and one pair on the bottom card |
| Six DIMMs | Two pairs on the top memory card and one pair on the bottom card |
| Eight DIMMs | Two pairs on the top memory card and two pairs on the bottom card |
DIMMs are installed in matched pairs in adjacent slots on the same card (except for the case where you have exactly two).
Highest density DIMMs in the lowest-numbered slots is a good idea, but not enforced.
You want to roughly balance the total amount of RAM between the two cards when possible.
If you accidentally fill all slots, the memory switches to double-wide for about a 17 percent average overall speedup.
Appreciate the advice here thanks everyone 🙂
