RAM Layout Recommendations for R620

Fixed.... Sorry Dell messed with all my formatting lol

So I originally bought 5 identical R620's.

I just replaced all the 8GB Dimm's in my production servers with 16GB DIMM's, so obviously I have a lot of spare of RAM.

I went to install it in my 2 DR Servers.
Loaded up the first one so it now has 24 x 8GB Dimm's.....
Then I moved to the second..... to load it up with 12 more 8GB DIMM's.

But I discovered I had added 4 x 16GB Dimm's to the original 12 x 8GB Dimm configuration (16 DIMM's total). Done so long ago I forgot lol.

It's dell RAM, since I would have had them spec it out and my server guy on our account advise on the physical layout.
(However I have to say the placement does seem odd..... but the memory layouts on servers now does give me a headache lol)

1) Now first is a simple question and I'm 100% sure the answer is no since I have 2 CPU's but if someone can confirm.
Trying to split this up and use 2 - 16GB dimm's in each server definitely won't work right?

2) Second question is should I leave the 16's where the are and just pop in more 8's in the remaining 8 slots? Or do some or all of these 16GB's need to be moved?

(Yes, I know mixing sizes isn't recommended but this is expensive RAM I'm not going to rip it out and stick it on a shelf. Plus it's worked this long.)

Here is the current configuration (the other server is exactly the same except right now it has 24x 8GB DIMM's):
Server - R620 (2 x Intel Xeon CPU E5-2630)
Memory - 2RX4 PC3L - 1066R (Dual Rank)
A1    8GB       B1    16GB
A2    8GB       B2     8GB
A3 16GB        B3    16GB
A4    8GB       B4     8GB
A5    8GB       B5     8GB
A6    8GB       B6     8GB
A7    8GB       B7     8GB
A8    16GB     B8     8GB
A9    Empty    B9     Empty
A10  Empty    B10  Empty
A11  Empty    B11  Empty
A12  Empty    B12  Empty

I'm assuming A8 and A1 should be reversed.

I'm myself or my admin just messed up installing them but I don't want to move anything yet until I know.
I do know the rule is keeping larger DIMM's closest to the CPU's channel wise right?

Thanks in advance,
