Windows 10: Problem with compressed memory process

If system interrupts are high, suspect a hardware/driver problem.

If you run Device Manager (right-click *Start and select Device Manager), and any device has a yellow warning icon overlay, then that device is not working properly and is suspect that the driver has problems and may be using up CPU cycles to try and run the device, and failing.

With a Task Manager window open at the same time as DM so that you can see the high CPU and system interrupt use, select the right-click menu of the suspect device, and disable it.

If the CPU use, and system interrupts drop to a lower level, you have discovered a hardware conflict or driver problem.

Without further information from you it is hard to know how best to proceed.

If you don't feel comfortable about disabling a device, because it may be essential to using the operating system, have a look at msinfo32 hardware resources and conflicts/sharing, and see if the problem device is sharing or conflicting on an IRQ, and if that device can be disabled in DM instead.

 

Hi,

Uninstall the latest Nvidia drivers. That will mean your system will use the ones packaged with Win10. That solved it for me, but I am trying to find out what is the latest version I can download from nVidia which does not have the problem.

For me, I have a GTX 570 card which was working just fine with Win10. Games ran smoothly, as did everything else. I was playing around in the Device Manager and saw that my monitors were both set to "Generic PnP Device". Since I wanted to see the actual model number there, I started messing around. First thing I did was upgrade to latest and greatest Mar 28 2016 Nvidia GeForce drivers. As soon as I launch a game, it was laggy as could be. FPS went from 2 to 184 back to 2, then to 99, then 1, etc. Unplayable. I spent all afternoon trying to google it, doing this, that, etc. I could see that "System and Compressed memory" was eating up 40% CPU or more, even more than the game I was trying to run (Far Cry 3). Finally I uninstalled the Nvidia drivers, and now the lag is gone. FC3 is back to 60 FPS.

My goal now is to find the latest version of the Nvidia GeForce drivers that I can install from their site. The added extras are useful, using the default Win10 drivers is fine for now but not my long-term solution. I found another forum post which stated they thought this problem was introduced in Nov 2015 with the "Tomb Raider-ready drivers, so I'll try some from Oct 2015.

 

What I don't understand is why Nvidia hasn't fixed the problems they have with Windows 10. There are an awful lot of problems reported in these fora that are directly attributed to Nvidia drivers, especially the new ones.

 

I no longer have this issue with the 358.87 drivers dated Nov 4 2015. If you want to give them a try, you can find them in Nvidia's archive and beta download page : Beta and Archive Drivers | NVIDIA

 

Hi

Thanks again for all the help

I have attached a photo of my task manager. The only thing running at this time is firefox with one open tab plus bitdefender

This happens after safe boot and clean boot

I have no conflicts in device manager no yellow triangles and have tried 3 different free apps that tell me all my drivers are up to date

I have also ran msinfo and there are no problem devices or forced hardware but under conflicts/sharing i have this

As for Nvidia drivers sorry for appearing stupid but im not sure I have any ?? or if I have I cant find where to uninstall them ? I have onboard graphics as far as I know on my intel chipset

Hi, you might try these ideas as an experiment (from a quick search):
http://answers.microsoft.com/en-us/w...6373607?auth=1

- disable audio enhancements (I've noted Cortana/microphone setup objected to these on mine)

1st post here may be of interest - note ref. to kernrate utility
System interrupts and High CPU usage

This one reminds me of Latencymon (another interesting utility that someone posting here found helpful in diagnosing System and Compressed Memory problems)
System Interrupts CPU (high DPC and Interrupt usage)

Resplendence Software - LatencyMon: suitability checker for real-time audio and other tasks

 

Right-click *Start and then open Device manager and post a screenshot - particularly the devices that are in the IRQ 16 cluster:

IRQ 16 Intel(R) 6 Series/C200 Series Chipset Family USB Enhanced Host Controller - 1C26
IRQ 16 Intel(R) Management Engine Interface
IRQ 16 High Definition Audio Controller
IRQ 16 Intel(R) 6 Series/C200 Series Chipset Family USB Enhanced Host Controller - 1C2D

Are any of these already disabled?

In Device manager, I would have bet (some of) these items have yellow warnings - but no.

With Task manager or resource monitor open to CPU use graph, disable these devices one by one, waiting for 30-odd seconds or more for each if you begin to see the CPU rate dropping off, and see what happens. For each disabling check the system Interrupts value. Screenshots would be nice.

What is the graphics driver? Intel or Microsoft Basic Graphics? It should have a memory address range, surely?

 

Hi

Screenshots as requested showing said devices with no issues and all saying drivers ok plus scrennshiot of Intel graphics driver info

Unfortunately I cant turn anything off or on or disable enable anything when CPU usage goes haywire so cant turn them off one by one and show screenshots but what i have done is disable them while CPU is low and no configuration stops the issue

 

It looks as though your PC has not been approved for Win 10 use:
Lenovo supported systems list for Windows 10 Upgrade - Lenovo Support (US)
Can you confirm? Has it worked satisfactorily previously?
An H520 is listed, not H520s.. but yours came, I think, with Win 8.

Can you confirm you've tried this:
My computer got so slow that the mouse was slow and jerky and I had to reboot. System interrupts was at about 30% CPU time. My PC is now with 5 days uptime and the bug seems to have disappeared. The following solution seems to solve the issue :

1. Right-click on the speaker icon
2. Select playback devices
3. Click on the speaker properties
4. Go to the enhancements Tab
5. Click Disable All Sound Effects
6. Click OK. You're done!


Do have a look thru this thread (one of the ones I posted earlier) - it may suggest sthg:
Solved Is this normal? System and compressed memory process ALWAYS at 20% cpu - Windows 10 Forums

 

I recently read about a similair problem on another forum and the problem was Onedrive.

Try disabling Onedrive and restart the computer, let me know if it helped *Smile

You might want to save files on Onedrive locally if you're using it. Don't know if it will delete files when disabling it.

Good luck!

 

Hi
I assumed that meant lenovo wouldn't support Windows 10 not that it wouldn't work but perhaps I am wrong. If that is the case it's too late to downgrade so I'm in trouble
*Mad

Windows 10 worked fine when I first installed it and for several months after however. I have tried the disabling sound effects but it didn't help.
I have downloaded kernview and latency monitor and will run them and post any useful news
I have also turned Onedrive off

 

If your PC worked fine with Win 10 and no heating problems, then looks like you're in luck. I've no idea what the difference is between and H520 and H520s. Maybe Lenovo hasn't tested every variant....

E.g. My 6 year old old laptop came with Vista. But after upgrading to win 8 (no drivers listed by HP), it experienced thermal cutouts - in Safe Mode. Fan running hard.. that's apparently typical of a mismatch of driver and hardware, but ran well if a little warm in normal mode.

If it used to run well, but not now, you might try
a. Safe Mode
b. Clean boot
c. uninstalling Windows updates

 

Hi

I did try clean boot ( see earlier post ) and problem vanished but only short term but i did forget safe mode after I was given instructions as to why it wasnt working I will try that

Well I may not be solving my issue but I am sure on a voyage of discovery

I installed and ran LatencyMon and got the following results







I googled these resul;ts and was told that one solution would be to download and rund driveclean which found and removed old USB registry entries etc but problem still exists.

I was thinking of getting rid of Bitdefender antway so now I will which will solve one of the hard page faults

It also seems a xperf is an option for me to use so I will do that when I can Extreme DPC Latency from USBPORT.SYS and storport.sys

This is now as interesting as it is annoying

 

Try clean boot and disable the red items in Device manager, then reboot:

IRQ 16 Intel(R) 6 Series/C200 Series Chipset Family USB Enhanced Host Controller - 1C26
IRQ 16 Intel(R) Management Engine Interface
IRQ 16 High Definition Audio Controller
IRQ 16 Intel(R) 6 Series/C200 Series Chipset Family USB Enhanced Host Controller - 1C2D

SPD.exe is reported as a virus

Hi

It seems my problem has vanished immediately after cancelling my bitdefender subscription and uninstalling

No issues at all since

Thanks for all the help and tips it has been very educational
