That would depend on the allocation patterns of your applications. On a
system with 2 GB of RAM and 2 GB of swap, I have tested:

overcommit_memory=2
overcommit_ratio=98

and I could allocate (and use) 3.8 GB of memory for an application
without triggering the OOM. You may need to test some values before you
decide what's best for you.

Good luck :)
