Dont confuse physical address space with anything related to virtual memory. The max page file size for Windows 8 ARM is 4 gb. There is no reason to believe Windows 10 on ARM would have a different limit by design. The same applies to Windows 10 x86 without PAE, what makes it even more unlikely.

ya you right man !

point yo if set to static bigger value is useless ?

guys if you need more VM then set it min to default and max to <free phone storage. system will automatically calculating how much need.

i try it:

days 1 i set to 256 1024, after 1day i see VM increase to 0.99GB,

so i want more i think ? restart my phone and VM back to 256MB

then

days 3

days 3 i set to 256 1536, restart, got VM 256 and after 1 day i see VM increase to 1.3GB

day 5 i just be fine right now, no need more ?

I just tried this with my Lumia 640 and changed it to u:\pagefile.sys 256 768

After Writing, backing out, and going back the string changed to 00000AEFEF0E0E0E2506. Is that normal? It still says 256 in the Storage App.

After using this in a Lumia 920 for 1 month with 1 GB of Page File and comparing that phone with the Lumia 950 XL; I can confidently say that for me it improved the multitasking. My Lumia 920 now multitask better than my Lumia 950 XL.

This doesn't mean that it's faster but when changing apps it is more likely that the Lumia 920 has the app where I left compared than the Lumia 950 XL. About the size, I didn't feel an improvement with 512 MB, it started to get better with 768 MB and definitely better with 1 GB.

I have no idea if 2 GB would improve the situation even more but I don't use that many apps to think it would.
[Windows 10 Mobile] marianodelfino:
That's because you don't have permission to edit the registry, you change the values but they don't stick. x50 devices might have problems with interop, search for a vcreg proper guide inside the forum.

For the 640:

1. Uninstall your interop tools.

2. Enter my drive and download the dependencies. After download install them ONE by ONE.

3. Download and install interop tools 1.9 from my drive aswell(takes 2-3 minutes to install with the explorer, maybe a little less, you don't need to sideload anything).

4.Enter the interop tools. Go to THIS DEVICE -> Sidebar -> Unlock -> Restore NDTK. Use the slider to enable it and reboot the device.

5. DONE. After reboot you will be able to edit the registry.

Pagefile has a logic behind is not like if you set a 8GB page would be better than 1GB. The logic is simple, the more RAM your device has the less the pagefile should be.Why? because it's not likely your device will use all the RAM at once so, setting the page too high will only consume space, you won't get any good use of it.
[Windows 10 Mobile] npoe:
I have monitored my Lumia 950 XL RAM usage and it is always around 500 MB of free RAM while I'm in the start screen. Sometimes it dips to 230 MB-350 MBs when using an app in the foreground and then goes up to 450-550 MBs of free RAM when I go back to the start screen.

All of the above is with a pagefile of 256. That implies that some apps are moved to the pagefile or terminated at some point. The best size for the pagefile should be determined using a combination of the apps that I normally use, the size of my RAM, how W10M manages the memory and the amount of free space in my internal memory.

I don't close any apps in my phone and I'm sitting in 935 MB of free RAM right now. Half an hour ago it was around 500 MB.

Bottom line, for my Lumia 920 between 768 MBs and 1 GB makes a difference in the phone multitasking ability (i.e. not closing apps). The experience of switching apps that takes a while to load (FB, Messenger, games) is better than in my Lumia 950 XL.

Error after doing the Changes

I changed these Registries -

HKLM > SYSTEM > ControlSet001 > Control > Session Manager > Memory Management > :

-"PagingFiles = u:\pagefile.sys 1024 1024" from "PagingFiles = u:\pagefile.sys 256 256"

But then, after reboot, I can't install any app from store which gives error for no Resource available, which is most probably Virtual memory error, because of Registry. I tried many times to change that registry to default value and many other values, but after every restart, it stays same as "PagingFiles = u:\pagefile.sys 1024 1024"

Is there any way I can reset that registry..??

What's the difference between having the page file at U:\ or C:\ ?

Is U:\ a link or a real partition? This since setting a pagefile of 1GB to it while it might be a partition of just 512MB clearly won't fit.

I have "moved" the pagefile to C:\ and can see it has been created there with the actual timestamp I created the file there, but nothing shows up at virtual memory under storage settings.

Will try and test again on U: , but until now having the file on C:\ does make the phone make feel smoother, but that might be placebo...

---------- Post added at 20:58 ---------- Previous post was at 20:17 ----------

Though I have no clue now where the pagefile is located right now when using U:\ as location, but I have noticed a huge difference on my phone regarding free storage space.

- When on U: the virtual memory is shown on the settings page, but also reduces the amount of free storage space with 1GB.

- When on C: the virtual memory is not shown on the settings page and while the pagefile can be located now in the root of the device via USB, which also shows the size of 1GB, the amount of free storage space is not reduced.

Performance wise there is no difference in having the pagefile on U: or C:

My two cents on this is that the root partition, which can be accessed with C:\, is already being counted as being in use for "System & reserved" already, so placing the pagefile in the free space on that partition will thus not reduce the storage space available for Apps, files and documents etc.

Hence I will go for C:\ as storage location for my pagefile, having an additional 1GB of space available and don't care about that the virtual memory is not being mentioned on "System & reserved"

I did the same and got the device bugged... you can fix the value but the device will still be bugged. Your problem was that you changed controlset001 instead of currentcontrolset which depending on your interop tools, i think versions below 1.9 currentcontrolset is at the bottom. On interop tools 1.9 or higher versions shows alphabetical properly, and you can see currentcontrolset above controlset001! The only solution would be a hard reset, i repeat, you can fix the value to show your vm again but the device will be bugged.

When I tray to save (Write) it just doesn´t hold the value; keeps on returning to 256 256.

Reboot or soft reset won´t make a difference.

I upgraded my phone to Windows 10 because I couldn't install navigator maps on sd card but I have a problem: when I try to read a online newspaper like 'La repubblica' and I'm scrolling it suddenly the system freezes and after 30 seconds the browser reloads.

Befefore the update, with windows 8.1 everything worked great.

Do you know what can I do to fix this problem ?

And, as you said, going to “Interop unlock, and turning on "Restore NDTK" was necessary.

Afterwards, attempting to set PageSys to 512 512 or 768 768 didn´t work; but once I selected 1024 14024, the virtual memory under the “storage icon” changed from 256MB to 1GB, and the phone loads videos quicker, and navigates faster overall.

How to reduce virtual Memory

hello guys,

My device is Lumia 535 dual

I've increased its virtual memory from 256 to 512Mb using interop tools (it showed 613mb in storage ), then i tried to reduce it back to 256 by putting the value u:/pagefile.sys 256 256 but now it is showing 1.75 GB of virtual memory.

What i did wrong ??

What are the Minimum & Maximum pagefile size(s) the you suggest? Just to know!

Also, I'm currently running Windows 10 Mobile 15254.527 (Last Updated August 14, 2018). It's running quite smooth in my experience.

I've successfully enabled tweaks like LED Notification (only its not blinking), Glance, etc. Thanks to respective people on XDA & few other sites. :o

But, I can't see videos in Instagram app in my Lumia? (In my case, videos aren't working -rest is smooth thou)

My guess is that Windows 10 Mobile builds have changed how Graphics are processed. In Windows Device Portal for Lumia 1020 I can only see GPU engine 0 running in most cases of 2D & 3D graphics.

And that is one of the reasons (I think) that Maps are not rendering streets in (say) Lumia 1020, and/or unsupported or older phones. :rolleyes:
[Windows 10 Mobile] marianodelfino:
The more RAM you have the less the page should be. For 2GB ram, 512MB~1024mb. I use a static size page, meaning min-max are the same value and clearpagefileatshutdown enabled. The use of gpu 0 only, might be caused by core parking. Try disabling it.

Force-Use GPU cores in Lumia

Ouhhh! I guess disabling Core-parking an old Lumia might be help for sure. But I don't know how to do that. Atleast, tell me registry location, if you can. Also, other instructions needed for that. Thank you.

Also, I think Maps may start working again, or maybe not. What do you think of Force-Use of most of the GPU (if not all) for doing the job? I will try doing that & see if it helps. But need to know about Registry Location for Core Parking. (I am also guessing that GPU is divided into different parts that can only do particular type(s) of jobs). Help!

Value max and value min should be 0. Do a full cold-start (don't restart, shutdown the device and then power on).

Disabling core parking will prevent stationary cores, all your cores will be active. Not familiar with the maps problem since i only use it for offline navigation and it works ok.

Hey J.Marian, you're really helping me explore some uncharted caves ;) Thank you. I do remain cautious not to change some unknown registry value, that'll make me regret later.

Now, my LUMIA 1020 has Virtual Memory of "1.00 GB" with u:\pagefile.sys 1024 1024 Thanks again. I am quite a noob to feel the snappiness yet.

But I can't resist knowing & editing sometimes.

So, I also changed the following:

In ...\MEMORY MANAGEMENT\SecondLevelCache that thing was at REG_INTEGER=0. I changed it to type: "REG_DWORD" value: "1". Since, I got S4 Plus MSM8960 in my Lumia 1020, which has L2-cache of 1MB. So, according to instructions on this ??Pandoon-optimize processor-L2 cache?? I changed this value. Now, I'm observing what happens. Things are working fine till this writing. I played a few games & songs & restarted it also. NOTE: Some people say that this L2-cache stuff doesn't works, nowadays. Also, the things were for PC's. But I want to give it a shot. Because Why not! :P

No progress with GPU Engine.

I tried following your core un-parking instructions (since Lumia 1020 got S4 Plus which has Dual Core Krait).

The thing is I don't expect anything more from Lumia 1020 now. Its working almost ohkay for me. This is the first & only phone I've bought. I think I can go with it for some more time.

I USED TO USE HERE MAPS A LOT. BUT NOW WITH Windows 10 Mobile 15254.527 I can't even use Windows Maps. They are not rendering streets in close usable-view. Streets are there in Zoomed-out though. So I am despo. to try-out FORCING GPU-ENGINES. CAUSE I've seen that WINDOWS DEVICE PORTAL for LUMIA 1020 shows most usage in GPU-ENGINE 0, sometimes upto 97%, rarely 100%. GPU-ENGINE 1,2,3,4,5,6,7,8 are always at 0%. Sometimes, only ENGINE 1,2,3 have shown 5-7% of activity.

I want to know, if you can help: Why GPU is behaving so? Where can I find GPU Registry Controls? (You suggested controls of CPU Parking, not, GPU.) Awaiting Response.
[Windows 10 Mobile] marianodelfino:
There are some profiles that you can change to prioritize GPU but don't know if that would serve your purpose. There's an app called CoreMon, you can find it here on XDA, that would monitorize your cores usage.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile\

Inside here you have some values you can change for better response, google what does each one. Inside tasks you have different Keys, each one has a GPU priority, search for the values meaning maybe that would help.

About maps, there are lots of things you can do about it. Use another app would be one, move to another w10m compilation such as 10586 would be another. Try installing here maps, i saw someone using it last year so apparently it works again on w10m. Windows maps works fine for me on 635, same build as yours. Maps doesn't work on my 550, same build. Don't really know what to tell you about it, works fine on one and doesn't in the other maybe be a config matter, one of my devices is fully unlocked with vcreg and the other it isn't, could be something related to capabilities? Don't know for sure, I didn't do any research about the maps problem. I know for sure that maps work on 10586 on any device, but that's it.

I really Thank you, so much, for taking your time to help me. At this point I'll try some things in my current build (Also, it seems quite stable to me, relative to other builds).

Or maybe just a little step-back to the 10586 build, might also try 14xxx. I guess I've also heard about 10586 to be the balance-striker in many ways. I think the time has come to stop pushing my device, now, almost.

After-all, everything is temporary ;) But I love this temp. chaos, until it 'is'. I really enjoy taking photos from Lumia 1020, also this is the first smart-phone I had after NOKIA X3-02. I don't know what to say.

I see that time is about to come. But I don't know what to go for next. Nokia is not as good as it used to be.

I'm not against Android (against Apple-**** though).

Lastly, if you or anybody could suggest me what can I go for as my next phone. (I really love RAW and Good-Smartphone-Photography, BOXY or BAR or EDGY Form-factor, also like XPERIA XZ1 or similar but its camera sucks) Main focus on CAMERA. Thanks.

OT, but regarding Maps, I haven't tried tweaking a lot on my Lumia 1020, because my main phone is a 950XL, but I never got MS Maps working on the 1020 or 920 with W10M latest builds. Their graphics engines are just incompatible with the app, I think, since Anniversary Update. Still works on Threshold.

As an alternative for the 1020 and 920 I use Navmii. This is an Open Street Maps client. The app usage is a bit quirky, but you swipe in from left and right to get to menus, and swipe in again to dismiss them. You install maps from the "Upgrades" menu item on the right swipe. The maps are compact but highly detailed, and are actually much better than MS Maps, or even HERE. And they work on the 1020.

Maps should work just fine on the 920 and 1020 with the latest WM10 versions. After reading your post, I grabbed my 920 and my 928 and they both render Maps just fine, in fact very smooth even when viewing 3D cities. The 920 is running 1709 without updates and the 928 is running 1709 with the latest updates. Their CPU/GPU should also be the same as the 1020. Also running the latest version of MS Maps.

You might want to give it another try or explore what changes might be causing it to fail.

Altering with modification of registry by RegEdit on the PC

Hello Everybody,

I watched a video at YouTube which named "Windows Phone Internals - Create a Custom ROM with Root Access". XDADevelopers did not let me add its link. Sorry about that.

So I have a different approach, but I am not sure that would work and I have a question about Windows Mobile Registry. Can be a problem to edit registry from a mounted binary by regedit on the PC? My phone is Lumia 640XL RM-1062 and OS version is 10.0.15063.1506.

For example:

1) I backed up my phone with WP Internals.

2) I mounted binary "MainOs" through Passmark OSFMount to the PC.

3) I mounted file "system" located in F:\Windows\system32\config in a hive by regedit on the PC and edited key "ControlSet001\Control\Session Manager\Memory Management\PagingFiles. I set the key u:\pagefile.sys 1024 1024

4) Then, I unmounted that hive. So the modified registry looks like OK.

5) So I can zip those and flash. But I have the following doubts.

My concern is to use that binary and flash to the phone. Would be any problem to download and edit windows mobile registry on pc, then to upload to the phone back? If this hack does not have a chance to completely burn the phone and I can return to my original FFU, I want to give a try.

Regards...﻿
[Windows 10 Mobile] nate0:
For that particular edit you can edit the registry on the fly, in mass storage mode, or in the partition for Flashing. Either of those methods will work for this particular hack as long as you don't reset the phone it will persist after the edit is done.
