There is not enough memory in the system

All kind time of day, I play today at the apex and suddenly the message POPs up about insufficient memory. Promonitorit through the task Manager and аиду64 - maximum load 65% (I have 8GB). This is most likely due to me disabling the page file. But I don't know of one, freely another 35% (about 2800мб), why the system says that her little memory? (Sori for the quality of the image, for some reason, took a picture, not zaskrinil)
