What motherboard do you use? I assume it's a dual socket. I really wish mine had more than 4 DIMM slots :-/
I use Windows as my host OS but run linux in a VM. I develop on both platforms. The main reason I need the RAM is because I work with some very large databases and I want most of the data loaded in memory rather than read from/written to my SSD
Just curious but what do you do with it? Hard to imagine most of that not sitting unused and wasted.
Lots of VMware virtual servers testing.
There are desktop motherboards that support 128GB of RAM, like the MSI Big Bang II.
