Windows 10: Large non-paged pool size

Hello,

Recently I've noticed my RAM usage increased to near 95-100% usage since I installed the latest update for version 1909 after several hours (over 20) of usage. I've done a bit of research into the problem and found out that the non-paged pool size increases to 6+ GB whenever this happens.

I've tried disabling Ndu, but that didn't seem to help. I tried updating drivers through Device Manager but it says that everything is up to date. I've used utilities, such as poolmon, RAMMap, and Sigcheck to gather information, but I'm not sure how to interpret what I've found.

If it helps, I have an AMD Ryzen 5 2600 CPU and a Gigabyte B450M DS3H WiFi Motherboard.



Thanks in advance for the advice!

Large amount of Paged Pool memory usage over time

I have been fighting with this for some time and I can't figure out what it is. Over time, my Paged Pool memory usage keeps climbing until eventually I have to reboot to clear it out. It is a tough problem to search for because most people seem to have a problem with non-paged pool memory and all of those problems get included in the search results.

I have 32GB of RAM and once the paged pool reaches around 18GB or so it starts to bog down and get sluggish. And when I say 18GB, I mean 18GB with nothing open. I have my typical tray stuff, which I have tried killing, but nothing releases the RAM. I have let it climb all the way to 32GB before, but then the computer becomes useless and took about a half hour or so to shut down.

When I run Rammap it shows that paged pool is huge, and in the process list there is a process called MemCompression that has an extremely large amount of RAM in use. Not the full size of the paged pool, but definitely really big.

There are several threads talking about using Poolmon to track down processes using lots of paged or non-paged pool memory, but the process on mine that is extremely large has a tag of Se, which is tough to search for in the strings because virtually every file has Se in it somewhere.

Right now I just rebooted again, so the usage is back to "normal" (if you consider 11GB memory in use normal for just having Chrome open) and my paged pool is around 2GB or so. It will increase again by this evening, so I will get some screen grabs of the Rammap and the process list. Any other screens I can grab that might help?

 

Non-paged pool usage is too high

Based on your calculations, how large should the non-paged pool be?

 

Huge non-paged pool on startup?

Hello. I just built a new computer and installed the drivers for it on w10. Everything works fine, but I have a non-paged pool of 5.7gb out of 16 on startup, and I'd like to do something about that. I checked under task manager for the non-paged pool,
but none of the programs there are taking nearly that much. I suspect it's the killer network driver, but I'd still like to confirm it. Any suggestions? Thanks!
