What Causes the “Out Of Memory Error” in Black Ops 4?

The Error can arise due to a number of reasons and causes but to make a list two of the most probable causes are

  • Low Disk Space: You are running out of disk space on the partition in which you installed the game
  • Page Filing Issue: The Virtual Memory Page Filing System does not have enough memory allocated to it.

Solution 1: Freeing Up Disk Space

If the disk space on the partition on which black ops 4 is installed is less than 1 GB then you have to free up space and make sure that the partition has an at least 1 GB of Memory Free or else you will continue to face these issues. Games like Black Ops require some additional memory to virtually store the game files on the drive which is why they require additional virtual memory on the disk in addition to RAM, therefore, in order to work efficiently, Black Ops will require additional space on the partition.
