Why does the "Out of memory" error occur when > 4 GB out of 8 GB are available?

Question

Windows

Hello.
When working in applications such as Firefox and Adobe Premiere Pro (simultaneously and separately) on a Windows 8.1 8GB DDR3 system, the message "there is not enough memory in the system" constantly appears. Even if Firefox 37.0.1 is the only application running and more than half of the RAM is free. Chrome with the same number of tabs does not reproduce the error. All software is licensed. The paging file is in automatic mode, there is more than 13GB of free space on the system disk (SSD).
Update: Chrome crashes too, doesn't even have time to throw a warning.

Answer 1

The lack of free memory often means the fact that the memory is highly fragmented and there are no large areas of free memory, so modern browsers like chrome like to crap, which is divided into a bunch of subprocesses, each of which wants to squeeze out a piece of solid memory, you can try to install Mem reduct and play around with the settings, 4GB helps me get rid of this warning in the vast majority of cases.

Answer 2

And your system is not 32-bit, purely by chance? :-) Then she will see only 4 gigs with 8 gigs in cash.

Answer 3

if the application is 32 bit, it will not be able to use more than 4 GB of memory by itself.

Answer 4

msconfig - boot tab - Advanced Options button - Maximum memory
is there a limit there? The checkbox must be unchecked.
