I would need either the model/part number of the memory you are using or the exact specifications. It would also be helpful to review the hardware log and memory configuration pane in the system setup to see if DIMMs are being disabled for any reason and also to find out how the system is detecting the memory.
There are many memory populations rules. Without knowing the specifications of the memory it is difficult to make a guess as to what the issue is. It could be a DIMM that is not fully seated, DIMM that is faulty, or a population rule issue.
My 8GB modules are Dell Part Number: X3R5M that came with the server. The previous 16GB modules are Crucial 16GB, 240-pin DIMM, DDR3 PC3-12800 Memory Modules.
Then we added more Crucial 16GB, 240-pin DIMM, DDR3 PC3-12800 Memory Modules, that's when we experienced the issue.
I guess I'll start with "what are the memory population rules?"

There are many limitations with the memory controller. These limitations restrict the number DRAMs per channel and various other restrictions. I need more information on the crucial memory before I am able to review your configuration.
The memory is populated correctly and I see nothing in the specifications that would stop them from working. I refer you back to my first post, check the logs for any errors or any disabled DIMMs. Also, check to see if all of the DIMMs are detected in the memory section of the iDRAC.

Bump.
What information do I need to provide? Can I get something that makes sense of the RAM population rules for this server?

Does this not suffice?: Crucial 16GB, 240-pin DIMM, DDR3 PC3-12800 Memory Modules

If you can't provide the specifications of the memory then provide a model or part number so that someone else can look it up.
