On that tab, the "Memory (Private working set)" column corresponds to what the "Processes" tab shows for "Memory". but these are usually small compared to process-private v.a.s.) Nor will the total of the "Commit size" columns add up to the "commit charge" (30.1 GB on your machine), because other things contribute to commit charge: Nonpaged and paged pool and some more "subtle" mechanisms like copy-on-write sections, pagefile-backed sections, AWE mappings. If you want to find out what's using committed memory you need to look at Task Manager's "Details" tab and enable the "Commit size" column. Part of the whole point of virtual memory, after all, is that you can have more virtual memory in use than you have physical memory (RAM). So, of course, RAM used + pagefile used can be larger than RAM used. (And at the moment it almost is that high, so reducing or eliminating the pagefile would be a bad idea.) So your "committed" could be as high as 32 GB. you appear to have a pagefile of about 24 GB, since you have 8 GB RAM and the commit limit is 32 GB. The whole point of virtual memory is that it can be much larger than physical (RAM), no?ītw. And that's too late for the system to say "sorry, we're all out of room." But it still counts against the "commit limit" because if it's it accessed in the future, it will occupy storage then. "Why is my “Committed” memory so much higher than my actual RAM space?" Because "committed" is mostly process-private virtual address space, and some of this can be in RAM and some in the pagefile.Īnd some might not occupy any storage at all! That's if it's been allocated but never accessed, hence not "faulted in", yet.
