I have a Mac mini, early 2012. I upgraded to 8 Gigs back in the summer and the machine runs much better. But now after a few hours, the system shuts down and I get a constant beeping. It started after the upgrade and I also installed Sierra. I have sufficient memory since my monitor tells me I have 2-3 gigs available most of the time.
MacBook, Mac OS X (10.6)
Can you hear your fans running fast and loud? Could be an overheating problem. Also rule out memory module problems. Try opening your machine and reseating the memory. Then test for bad memory. I use Memtest http://www.memtestosx.org/

The RAM may be seated incorrectly or may have gone bad. Run Apple Hardware Test and see what it reports:

Also check with Rember:
macs are picky with memory modules so if you picked up some std. ones it could be the issue
and of cause memory modules are sensitive to statics so if one don't install them carefully one can damage them
and as stated if they are not proper inserted
all can cause periodic defects which would explain your issue
I would only get modules from crucial myself
