I'm using 10.0.433 and looking at my inventory details (Computers > Computer Details > Hardware > Physical Memory) I believe that where it says "Total Available RAM" the name is a bit misleading, as this appears to be the the maximum RAM the system could support, *not* the total that's in the system. I've checked this on many systems that have 8GB or 16GB and it always lists 32GB in this field.

If this field were renamed to "Maximum supported RAM" I think it would be less confusing!

Thanks!
