Yes - I am not saying my entire farm has that much ram. You can get away with much, much less, but I have servers that go that high.

Did I read that right you have 768GB of RAM?

This is kinda new to me - Just so I am clear - unganged systems would perform better if I have say - a caching system with limited threads each pined to a specific core (we do this for processor cache anyway) while ganged systems would perform better it I was spinning up a new thread for each request and had a large amount (say 768GB) of ram running something like PostgreSQL where threads are being fired up and down many thousands of times a second but the data
 they seek is mostly in main memory.

On-board bios usually will not allocate that much however. And by usually will not I mean I have never sen it do so, even in the days of ghetto ram thieving by graphics chip-sets.

But why does CentOS not register all of my memory? Why less than 3/4 of it?




Perhaps the bios has allocated a chunk of it to onboard video?
