a quad-rank memory module is installed, then only one other memory module can be added to that channel.
The channels are {1,4,7},{2,5,8},{3,6,9}, so if you are using quad rank modules you can't populate slots 7, 8, or 9. You can only populate the first 2 slots of the channel. A maximum population with quad rank modules would be 1,2,3,4,5,6.
Your modules should be populated in slots 1,2,3,4 on both lanes(A, B) if you are using optimizer mode. If all of the memory is not available in the OS then it is likely the memory is not installed properly, some of the memory is faulty, or the OS has a memory limit you are hitting.
