4 GB is enough for all that with a bit left over.Īlso, some built-in graphics don't have their own memory and use system RAM further cutting into the memory you need to run the game.

Although the game will only use about 1.5 GB of RAM, Windows always needs some memory for background tasks and keeping the PC running. RAM is about a thousand times faster than a hard disk, so you really want to avoid any virtual memory activity when playing DayZ.Ĥ GB is a lot more suitable for running DayZ. This can lead to serious thrashing of the hard disk and slow down the game. If Windows runs out of RAM, it will start using virtual memory - to make space in the RAM, Windows will copy some of its contents to the hard disk and copy it back again when it needs it. You need to close absolutely everything that is not essential to keeping your PC running and I would recommend a fresh boot beforehand just to maximise the amount of available memory. 2 GB will run it, but it leaves almost no slack. Bohemia say you need 2 GB as a minimum, but I really would recommend 4 GB.
