I’m having the worse time trying to configure memory for my r610. I have a handful of 8g and 4 g sticks. I’ve tried every imaginable combination with setting the number evenly among the two processors. I’ve also tried with just the 8 g sticks in different slots and the 4 g in different slots without mixing the 4 and 8. The 4 are all identical and the 8 are all identical make and speed. Is there a certain increment that needs to be in place on both like 16 on both, 32 on each cpu etc? Basically the server starts up then shuts down after about 15 seconds, nothing shows on the screen at all. I’ve been working on this on and off for weeks!
I'd start by getting the server down to the minimum to POST, in effort to first eliminate that power cycle behavior you're seeing. I wouldn't expect to see that sort of issue , instead of a message.
I'd recommend testing both processors separately in in processor slot 1 while only populating DIMM slot A1. If the server continues this power cycling behavior, even in this minimum to POST configuration, that would certainly suggest we have an underlying hardware issue. I'd suspect there may be one anyway, simply because you already mentioned having tried several memory configurations. As far as your question goes, if all the DIMMs are identical (except for capacity), then the only concern would be making sure that both processors 1 and 2 have an equal amount of memory for each bank. Ideally, you'll want to configure the memory in such a way that it is uniform across all the channels in both banks (assuming you're wanting to use the standard memory configuration, and not an advanced memory configuration).
For reference, the minimum to POST configuration is as follows:

Advanced ECC.
Or you can use Optimizer with them laid out:
SERVER 1:
CPU1: 8GB, 8GB (slots 1 and 2)
CPU2: 8GB, 8GB (slots 1 and 2)
SERVER 2:
CPU1: 8GB, 4GB, 4GB, 4GB (slots 1, 2, 4, 5)
CPU2: 8GB, 4GB, 4GB, 4GB (slots 1, 2, 4, 5)

Both are dual processor platform.

HV2: http://speccy.piriform.com/results/cu5W0JpEp7tCKgDgWlzoTic
Does that information help?

Are your DIMM's RDIMMS or UDIMMS?
Assuming RDIMM's:
SERVER 1:
CPU1: 8GB, 8GB (slots 2 and 3)
CPU2: 8GB, 8GB (slots 2 and 3)
SERVER 2:
CPU1: 8GB, 4GB, 4GB, 4GB (slots 2, 3, 5, 6)
CPU2: 8GB, 4GB, 4GB, 4GB (slots 2, 3, 5, 6)
In each server, the configuration for BOTH CPU's must be identical - number and size.

How many CPU's do you have in each server?
You can't split that exactly evenly.
32 in one, 40 in the other is the most balanced you'll be able to do.

RDIMMS. And what BIOS memory setting do I use? Optimizer?
