Windows 10: Non-paged pool memory exceeds 20 GB

My machine has 48 GB of ram and by the end of the day, all available ram is used up by the non paged pool. I have run poolmon and watched EFSM grow to over 2 GB, then show as a negative number, eventually settling at -1 which indicates EFSM is using so much memory it has exceeded the integer value displayed in poolmon and is only culprit. I have tried using process explorer and task manager and there isn't a clear user of to many file handles. Shutting down all applications doesn't release the memory, so it is something running in the background, but I cannot determine what. I have no encrypt

Problem with a non-paged pool

I know that a non-paged pool is a memory that is used by drivers to allocate memory. Usually it takes about 200 MB but I found out that it grew up considerably and get 1.5 GB. I just have 4 GB of RAM on my PC

1.2 GB Paged pool does not seem unreasonable for a system with 32 GB RAM. This value is higher for systems with large RAM sizes. In any event it is hardly likely to be the cause of your problem.

The paged and non paged memory pools are used by kernel level components such as drivers and the kernel itself. The paged pool can be paged out at the memory managers discretion while the non paged pool must remain in RAM at all times. Task Manager will not tell you how much of the paged pool is in RAM.

Memory usage in any modern OS is controlled by the system memory manager, always with the goal of maximizing overall system performance. When available memory is plentiful, as is shown in the screenshots, the memory manager will allow processes and other Windows components to use pretty much whatever memory they want without restrictions. But if there is memory pressure it is fully capable of reducing the paged pool usage to a small fraction of it's current value. But it will only do this if needed. Doing it at any other time would serve no useful purpose and would likely impair performance. Note that this is the RAM resident portion of the paged pool, not what is shown in Task Manager which would be unaffected.

High memory usage, even if it is seriously abnormal, will not impair performance unless it causes a shortage. I have seen many Internet articles that get this wrong. It is not unusual for the paged pool to grow over time. Unless there is a memory leak, and there is nothing to suggest that here, this growth will stop.

Oh, I see! Thanks for the clarity!

Pageable memory controlled by memory management...that makes ALOT of sense! Oh well, at least the page pool stops at 1.2gb memory so I still have plenty of ram leftover for multi-tasking purposes. For virtual memory, I left it at system managed on C:/ drive. Otherwise, I'll try to update the network drivers and nvidia drivers. I know Killer Network drivers are highly proneable for memory leaks.

Say, did Intel made an update of Intel Rapid Storage drivers for 4th Gen processors?
