Maybe you can, but should you? I think 2 reasons to NOT do it.
1. It's never a good idea to mix "non-exactly matching" memory-DIMMs inside a single machine.
2. Three DIMMs means one memory-bank is un-even and now running Single-Channel. Pretty sure that means the whole machine drops-back all memory to (the slower) Single-Channel memory scheme.
These are the supported ram specifications for the R12: R12 User Guide page 14.
3 x 16 is not supported. Besides the fact a 3 stick memory configuration is typically not supported, you are also mixing different memory modules and speed, and without populating either 2 or 4 banks you will also loose out on dual channel, or it might work improperly.
I would not recommend using this configuration as I am pretty sure it will lead to undesired operation and errors.
Agree with the others that say 3 sticks is almost certainly a no-go.
If you are interested in parting with the OEM stick, and it's a jv223 compatible one, that would let me pair up my single stick, and you could then standardize on 2 or 4 of the 3200 sticks you already bought.
What about 4 sticks same speeds different sizes? 8x2 and 16x2 creating 24 gigs of ram in each channel. I know its not in the manual but I want to know if it will work, and if not why

PM me if open to that.
