Second, it's a 6-channel configuration. Just balancing equal amounts of total memory for slots 1-6 and 7-12 may lead to memory problems. Optimally, you want to match your RAM with the respective slots to reduce the possibility of errors, but even that is no guarantee. Match as best you can, the RAM's capacity, speed, timings, voltage and manufacturer.

The link from Colmike9 indicates the 32GB sticks should be in the odd slots.

When done, you may want to run a RAM test.
Thanks for the feedback.

As soon as I added ram and rebooted my issues were resolved. So it must recognize and utilize it, but you're 100% right.

Install the 32GB DIMMs in the first slot of each channel pair.
^ That's probably what is throwing it off.

I'm going to swap them around to the proper slots.
