Dell bios "memory installed" vs. "memory available"
I have a brand new Dell Precision 5860 Tower, and installed 128GB of Corsair RDIMM memory, yet in the BIOS it states only 32GB are usable, how do I get all 128GB to be usable?

All modules show in BIOS, 16GB in all banks, it says 128GB installed but only 32GB available.

I have exactly the same issue but with 192gb RAM detected but 32gb available. Did you find any solution?

Yes, through Dell tech support, my motherboard was bad and they sent a new one.
