Non-Paged Pool problem

[Robert F.]

Excuse my grammar but please understand my situation.

I have RAM non-paged pool problem that I cannot able to fix. I just brough a new gaming laptop for 9 months without a hitch (Alienware/Dell, Intel i7-9750h, 16gb RAM, my network adapter is Killer Network E3000 2.5 ethernet controller). I also kept an eye on my NP pool that stay consistently around 550 to 640 MB for few hours of use and nothing out of ordinary (even on safe mode, it stays around 300mb).

However, something went wrong when I recently receive a Windows update that cause a repeat the same version after restarting, my connectivity become very limited use (blocked Dell website and etc). So I tried update my Windows OS in the correct version manually from the Microsoft page.

It resolve the problem, however I've noticed my non-paged pool just suddenly bump up from 550mb to 850mb on reboot. I tried to doing system restore back before update occur but the number still persist.

I tried updating my drivers via the IOBit Driver Booster, reinstall my antivirus and network adapter, nothing. Upgrade windows version 2004, change NDU to 4 from registry editor, booting safe mode, run on windows memory diagnostic (no results on event viewer), clean reset, factory reset and STILL stuck with the 800 number.

I'm not sure if this is normal but now i'm worried that it will increase in the future. It may have something to do with the Windows update or my network driver that I wasn't aware of but I'm running out of alternatives here.

Is this increasingly taking more and more RAM, or did it just change after the update? Unless it's a memory leak, I wouldn't worry about a 150 MB raise in it. Differences in the update and/or drivers could be responsible.

As far as I know, this is mostly for drivers. Non-paged means it can't be paged out to virtual memory and paged means it can.

It just changes after the update and the pool hasn't increase more RAM when I use the computer for few hours. It stay persistent around 840 up to 920MB or 1GB.

I'll try to look thoroughly into the drivers again.

Its going to vary from one moment to the next, thats just what it does.

Non Paged pool is a kernel memory that does not get paged into the page file when Windows applications need memory. In fact, it is that kind of memory that always stays in the physical memory and never paged out. The non paged memory is used by kernels and the device drivers for accessing the data where you are not supposed to find page faults.

In other words
Non-paged pool is used by drivers to allocate memory which they need and cannot be used when Windows runs out of free physical memory.

If you have a lot of stuff running in the background that could be a logical cause for high usage though. Or a driver has a memory leak
