[SOLVED] Is 48gb of RAM possible in my set up?

[AlienObs]

Hello all!
I'm currently running with a MSI B250m Mortar MoBo, and have 32gb of RAM, 4x8gb DIMMs . I'm thinking of upgrading the RAM, as I am a music composer and sample libraries need lots and lots of it (running the current project, task manager was reporting 800MBs free of the 32gigs, making things, unstable at times....)
As I don't have more free slots for more sticks of it, I was thinking of replacing the 8gb DIMMs with 16gb ones. Is it possible to make the transition in stages? More specifically:

1. Can I replace just one stick, making the total 40gb?
2. If not, I will have to replace 2 DIMMs of 8's with one 16gb one, leaving one slot unused, totaling again 32. Then could I populate the free DIMM with another 16gb DIMM, and leave the other 2 slots with the 8gb sticks, totaling 48gb? (2x16 + 2x8)

Is any of the above possible? It would be ideal for me both money-wise, and for my use (I can't imagine needing more after that...... (that's what I said when I got the 2nd 2x8gb ones...))

PS. My RAM sticks are these: Corsair Vengeance LPX 16GB DDR4-2400MHz (CMK16GX4M2A2400C14), and the one I'm thinking of getting is this: (CMK16GX4M1A2400C14) , same frequency and CAS Latency.

Thank you!

As always, mixing RAM may or may not work.
There is no way to say "100% yes it will work".

Recommend you just buy a 4x 16GB set, for 64GB.

you can but it is recommended that you use matched sets instead of random sticks.

it may work but it may not so be prepared for issues

For what you are doing, I would definitely buy a matched set. To be honest, when you're starting to get up into memory capacities of those sizes, you really need to move to a workstation platform that's using registered ecc modules for stability and even more capacity.
