New reg-hack: MemHack. Pre-Alpha.

I fiddled around with my wm6'd hx4700 (thanks kuzuhara!) and a registry editor and found a way to make it regard SD as ram and xip from it.
This renders my device to achieve usage smooth enough i allow myself to reffer to the device as a mini-umpc^_^
For SD only atm, miniSD may or may not work depending on your devices driver. No MMC for the time being.
I sooooo hope this isn't old news
Here's to me not ****ing any of your devices up, it worked wonders for me.
P.S
IMPORTANT!
Delete the Program Files folder and reset again once you see the SD's been renamed to Program Files2.
On the next boot it'll mount as Program Files and everything will load from it.
Excuse me, my brains are stuck in google translator mode
4.11.2007
It seems i was rather in the wrong and am taking a whole new direction.
One which involves reading more carefully before i charge head into the guts of windows embedded.
Will take me a while until next post, and it might become hx4700 exclusive, but i promise you some cool stuff to come yet.
Anybody wanting to make their SD into Program Files to save space,
just start resco reg editor and change hklm\System\StorageManager\Profiles\SDMemory\Folder: Program Files.
(Originally is SD Card).
You can also try messing with it, making it into diffenent sys folders, just be careful
Mine is currently application cache (Volatile) and [email protected] Files.
(Running sweet with what i got to with the enablement of complete graphics accelaration, except for a minor hang up when returning from sleep).
Sooooooooooo...
ONLY DOWNLOAD AND APPLY THE CURRENT PATCH IF YOU KNOW WHAT YOUR'E DOING AND WANT TO GIVE BEATING ME TO IT A SHOT!
I'm hoping for a next release in a day, but not necessarily of this project but of an off-chute.
BTW, is it just me or is WM real *nix like?^^

anyone tried this ?

Downloaded, but waiting to see what others think.
Want to know what it does to the SD card and device as the readme does say to move the devices contents of its program files folder to the sd card?????

downloaded it too. but i notice its his forst post.

Lol... it's my first post, sorry..
All it does is make the device call the card drive "Program Files" and set a swap file that's used as most device memory (don't worry, it's faster than most none-nand flash). i had to leave a small buffer in device memory though.
The memory file is unallocated, so just don't forget to leave 528MB free at all times.

Re-read the original post
It is and will be updated with periodic updates should they come.

I've been using it for 72 hours now.
It takes the odd reset to free up memory, but nothing worst than what we had before.

well if all thing got wrong.. anyway to revert it back?.. well ofcourse hard reset is one of it. uhmm.. lets put hardreset aside first..

well.. cant wait to test this.. i made a whole backup of my registry so if thing went wrong.. ill just restore the registry backup..

Good point doube_ofour.
Just export the StorageManager registry key before applying the changes, and if worst comes to worst restore your backed up original.

So, anybody else installed and can connect to tell the tale?

I made a cab with the regs and installed it But I'm still experimenting .. Nothing bad happened so far how do i know the device is faster ?!! how did you measured your device's speed ?

So let me get this straight -- it will use the microSD in my TyTN as RAM -- the icky sticky stuff I run out of because internet explorer, pocket player, and spb mobile shell grab it all for themselves?
Is there any way to specify how much of the SD card is used as RAM -- since I don't really need 1 GB of RAM on my device.
I saw your post about 558 MB free but didn't quite understand it. You also said you need the odd softreset to free memory? but why would you need to free up a few MB when you have access to hundreds?
But thanks for sharing with the community -- if this really does work out well for us, that's pretty freaking amazing.

@DuperMan
Does this hack simply make our "Storage Card" transform into "Program Files"?.. Thats it?.. cant see any speed improvement.. besides my memory usage increased by that means my device will perform slow..
My "Program Memory and Storage Memory" Stays the same as 47mb total on both memory..

Exactly Ragart!
Only it's set to use miniSD, i think you'd have to mess with it a little to make it work on miniSD... if response is good i'll make a mini version.
Remember - It's only been tested on wm6 hx4700!

in my case my program memory decreased by something around 10mb ! and I can't see any improvement in speed too ...

miniSD, hmm? Well that's the slightly-larger brother of my 1GB MicroSD. So I guess I'll just watch the thread and see others' reactions before I try anything (though I do have fullbackups)
Thanks for the quick response. So how much RAM does your hx4700 'have' now? and did you set it to 558 extra for a reason? Just curious questions from a person who doesn't understand the intricacies of reg editing

@doube_ofour:
Use it for a while, constant usage should be smoother. Did you free the space up by deleting the old Program Files as well?
Use it to surf for a while, multiple windows style, and you'll notice the difference.
Also, don't be mean to my hack Don't load it to spite, wait for each app to load and keep on starting apps without (majorly) worrying about a system crash.
@hma4:
The age old method of feel
It doesn't boost anything per say, but your device shouldn't be as compaction ridden as it was, so less mem degradation over time=more time between resets under heavy work loads. and i mean heavy. also, multi-tasking is MUCH more usable.

@ragart:
I set it to have a 512Mb paging area on the SD, plus 512kb in main for caching and another 16Mb for caching on SD, so that's a total of 528.5Mb overall mem, 16.5Mb cache and half a gig paging (good for them internet chaches etc..

i check on the registry that u have made in ur reg hack. seems like all the folders etc is the same even for a miniSD card ... so do u think it will work on miniSD too?

QUOTE: "Speed up your Metro HTC Mogul with a Micro SD Card I would like to share this hack with my friends that have a smartphone on metro pcs.
I found this hack on a different site, tried it and works great on my mogul (flashed). One way I tested to see if it worked or not was by using Opera mobile. Everytime I surfed the internet on my phone, Opera would pop up saying i was out of memory (I have so many apps installed on my pda) and to close the tabs. It got so annoying that I uninstalled it and have been using PIE since then. Until recently, installed Opera mobile again, and notice the difference with this hack. No more pop ups. I went from site to site and it loaded it up. I notice major speed. I went to sites that had a hard time loading without the pop up warning me. This time, no pop up and fast upload... Now Opera mobile is the best web browser. My phone also has less freezes and boots up very fast after a reset.
I have an Kingston HC 8gb micro sd card and it works great.
As usual, use this tweak at your own risk.
How to use Micro SD card as RAM
1.Open a new folder “Volatile” on the SD card
2. Change the following key, using the registry editor:
from \HKLM\System\Filesys TempPath = \Application Data\Volatile
to \HKLM\System\Filesys TempPath = \Storage Card\Volatile
3. Turn off the pocket pc with the power button for about 30 sec (not soft reset/hard reset).
4. Turn it on again.

I tried this in my Mogul and it seemed to work with my MicroSD 1GB. I noticed it booted up very fast, but the Opera Mobile 9.5 beta still showed Out of Memory. I guess I'll just have to wait until my 4GB MicroSD comes in from Amazon! There is some speed difference though with both on. No wonder it worked so well on his phone because he had an 8GB MicroSD! Anyways, just wanted to let most of you guys know.. PEACE

I posted this same message on the original thread as well.
This shouldn't work for the fact that it's not giving you additional memory, all "folders" in the phone are part of ROM memory, not RAM, so even tho you point that at your sd card, it's still not giving you back any ram which is what the Moguls lack, I think it's just a coincidence that you see a different in Opera. To prove me wrong, undo this hack, (reboot your phone) check your "free" ram, and then redo the hack reboot, and check it again.
You should see the exact same amount of free ram. And therefore won't gain any benefit.
Another thing, depending on your SD card, some being faster than others, if the SD card memory is slower than the built in ROM memory of the phone, this could actually lead to things being slower. I imagine in your case you have a fast card, and you see speed improvements because of it being able to write faster to the card than your ROM, but not any other benefits.

WOW
Best registry edit hands down i have about 7 apps open and it isn't lagging or freezing the apps i have open are thumbcal total commander tcpmp palringo calculator skyfire W.V.D. and task manager ... simply amazing and unheard of opening this many things with out lag just wow

hmmm doing some testing now .. will report later.. so far so good.. BTW
the regedit it damm cool..

I have cabbed up all of these tweaks for those of you that don't want to do the registry edits yourself. I have tested it with the emulator and it works great, but install this at your own risk.
Enjoy,
dwizzy130

Now it says I'm using up 10% more RAM than I was using before. Doesn't work for me....placebo? Has anyone else looked at their RAM usage?

Un mod

This is a very interesting idea. I've tried it and also found the loss of free ram to be a problem. But I'm running M2d. I tried dwizzy130's cab (which uninsulated with no prob). The volatile folder was populated with hidden files but i did get the low mem warning.
dogw/mogul: Are you running a stock rom? Whats your setup? I'd like to see if i can reproduce your results. I have made so many mods to my phone that one or a few maybe causing the prob. Maybe a different rom/radio/setup would produce better results.
This is an eyebrow raiser for sure!
Edit: Ok, By following the instructions manually I have the edit in place with out the extra loss of memory. The phone will still close apps after a point but your are correct in saying that the lag is reduced! It is noticeable. I'm thinking of dropping M2D and going back to dcd 3.4 just to see what performance would be like.
has anyone removed the SD card just to see what will happen?
I'm running M2D Reload 1.1
DCD 3.6.3
Radio 3.4
Sandisk 8GB HCSD

the cab install makes my phone use about 10% more ram but when i uninstalled it and just have the first hack i had 10 programs open including s2p and wmp playing music on both and still ran pretty smooth with very little lag. works nicely. i have 4gb card and 2gbs taken up by music and cabs ect. the other 2gbs is free.

I originally posted that on HowardForums... my mogul was fast and never lagged... but, I like to experiment with tweaks and 3rd party apps... so I had to do a hard reset... here is where an issue came up... using Resco Backup, I was unable to successfully restore for the fact that it was tweaked toward the SD card... my suggestion... use Sprite Backup... make an original exe copy and save it to your external card... then save another exe copy of the tweak version... so now you have two back ups...
Now, with the opera mobile... use this tweaked version of Opera Mobile browser http://forum.xda-developers.com/showthread.php?t=459378
No more "out of memory" issues Opera Mobile with Dexter's version....

I am still using my old 1GB SD card I had in my old phone (LG VX8300). Since I use orb for everything, I didn't see a need to get a new card. But with this hack I am tempted to do so. Hmmm got to think about this one.
edit: going to do this hack first then see if there is improvement. If its slow but have more memory then I will definetly get a faster card.
edit (again): can someone make a cab file for the first set of registry settings? Thanks!

If you were using your microSD card as RAM it would last you a few hours a best, cards cannot sustain the amount of data writing required to emulate RAM. Plus RAM operates on a bus directly with the processor, hence why it's directly assignable in assembly, which absolutely is not the case with SD cards which have to deal with a file system and interfacing hardware. Honestly extending RAM onto an SD card would make your phone run infinitely SLOWER.
Maybe there are other parts of this "Hack" that work but the idea that you can use and SD card as RAM is simply garbage.

ok cool I don't want do it then. u know that opera mobile that monte linked is great. no memory errors. It just doesn't work too good in landscape or with a hardware keyboard.

Ok so I installed the cab but I don't see any change. I still have 12 to 14MB running Manila 2D. ideas? I have 300MB or space left onmy SD Card

As I said in my first reply, this will NOT give you extra memory. Depending on the speed of your SD card, it may increase the performance on some programs, but there is no way to give the phone more ram with any registry changes. You would have to write a very low level driver that would then cause it to see additional storage as available memory, but since it's not ram, it will be extremely slow. On the original PPC's, 2003 and earlier, it had no rom, just ram, and it balanced the storage and available ram with software so that you could adjust. With the newer versions of windows mobile there is ROM and RAM, each with it's own function. So unless you were involved in the original development of the OS, it's doubtful you would have the knowledge to be able to write this kind of driver, and therefore it will probably never happen.
So this is a hack worth testing, and if you have a very fast memory card, you may see some improvements, but it will not give additional ram, and could actually cause your phone to crash if you remove the memory cards because background processes will be utilizing the memory card.
My suggestion is to not even bother with this unless you just want to test with it.

Moving the volatile storage from FASTER internal rom to SLOWER external rom is not going to get you any additional RAM, and at best will simply slow things down.
Placebo caused by the soft reset that you must do.

regarding the statements about the tweaks or cab file that the other guy provided causing you to lose ram. That is correct and thats what speeds up your system. Increasing those values allocates free ram for those specific areas speeding up the filesystem and speed of the device. So technically you didnt lose any ram its just being used for other parts of the devise to speed it up

I saw no improvement... could just be me. And my audio manager would just skip through all songs with this reg edit applied. When i put it back the way it was audio manager played all songs fine.

Wow.
Wow. I manually did the reg-edits just now and I'm not on crack. Manila 2D is considerably smoother, Skyfire loads much faster and I was able to open up multiple other progams without any lag. This is ridiculous! Nice find!

My phone ran much slower with the update, I did it just for sh*t and giggles, and was right, no additional memory, and apparently my 8gb sd card is slower than the onboard rom because it ran probably 15% slower.

Hey, thanks a lot!
Is that stock R3AA you tested?
If so, no major differences, I guess. Slightly faster RAM access?
Wow, was that SKTools that you used to crank up your card read speeds, or did you also use SD tuneup?

yes stock R3AA. the only tune up is via SKtools (in attempt to keep all things else equal ) and it does look like RAM access and floating point are the only area that's better than R2AA. I'm not sure why my card read speeds improve by 3 folds, I only did the 6 improvement area.
One thing I do find the overall performance of the phone is better, most significant improvement is the youtube video playback. There's no video stuttering which happens in the R2AA ROM. As for the rest (as in the perceived improvement) it might be due to a clean/hard-reset state. Only times will tell.

Speed your Shift for a couple of $$

This is not an advert, this is just to tell people who accidentally missed
the
READYBOOST - PREFETCH - SUPERFETCH feature in Vista/W7
I've been working with this feature since the release of Vista, it really helps, and it certainly does on the Shift.
Basicly, you reserve a part of your SD card (4GB) as an extra
"cachefile" (It's all done by the OS) and for all small random I/O
your Shift will now read from that part.
It get's faster over time.
Check out this blog :

yes possible inxp
go to virtual memory settings in xp....
on virtal memory / page file remove all hdd etc and set them to zero page file.
now select your sd card and select it as virtual memory or page file and nowxselect let windows manage page file/virtual memory on sd card.
apply and ok .
the key idea is to hvae all virtual memory on sd card and none on hdd...i have been doing this for many years.
more instruction on browsing to virtual memory settings/ page file on xp below
To manually change the size of virtual memory, follow these steps:
1. Click Start, click Run, type sysdm.cpl in the Open box, and then press ENTER.
2. Click the Advanced tab, and then under Performance click Settings.
3. Click the Advanced tab, and then under Virtual memory click Change.
4. Under Drive [Volume Label], click the drive that contains the paging file that you want to change.
5. Under Paging file size for selected drive, click Custom size, type a new paging file size in megabytes (MB) in the Initial size (MB) or Maximum size (MB) box, and then click Set.
6. Click OK to close the dialog box and apply changes.
Note After you change the size of the paging file, you may be prompted to restart Windows. If you are prompted to restart, the changes will not take effect until Windows is restarted.

yes it will work on any windows pc or laptop, just follow the instructions for vista or xp as appropriate

I tried ReadyBoost and Superfetch on my Shift and monitored the memory usage with the Process Explorer:
These two services need additional 100MiB of physical memory. So to have a SD cache with a speed of ~5-10 mb/s you give up 10% of you RAM. Bad exchange!
As long as the Shift's 1GiB memory is not fully used the device feels a bit smoother. But as soon as you reach the limits and it starts to swap your performance will drop even more than without these both services.
ReadyBoost and Superfetch are making the Shift faster - and also slower when you really need the performance.

dont use ready boost or super fetch services of vista, use the xp trick for virtual m

These two services need additional 100MiB of physical memory. So to have a SD cache with a speed of ~5-10 mb/s you give up 10% of you RAM. Bad exchange!
As long as the Shift's 1GiB memory is not fully used the device feels a bit smoother. But as soon as you reach the limits and it starts to swap your performance will drop even more than without these both services.
ReadyBoost and Superfetch are making the Shift faster - and also slower when you really need the performancoe.

dont use ready boost or super fetch services of vista, use the xp trick for virtual memory as outlined on my earlier post for vista as well.
remember the key forspeedup is to decrease the read/write from hdd during mem paging process, hence if all paging memory is allocated to sd (which is faster to hdd) and noe allocated to hdd, the os will work faster...this goes for all os xp,vista,w2k,wserver2005...and same for linux or osxor unix..

page pool what is it and how it affect when changing?

after i got an idea of what is a pagepool, i have some questions to clarify it, especially that i'm trying to figure my problems wich is maybe related to internal rams.
so i'm using garmin xt and during or when closing garmin i got a msg "your system is runing low memory", and when i'm playing need for speed undercover, i got my car distorted and the sky got some black mappings, but cars got distorted lines and triangles.
i checked the system memory and see that ther is storage and program
storage total:181.47, in use : 104.85, free : 76.63
program total:336.93, in use : 144.65, free : 192.28
now which one is the rom and which one is the ram?
when i run in low memrory does that mean low storage memory or low program memory?
is there a way to maximize it in order to not run low memory. (knowing that i do clean ram, and close all running apps)
does the page pool solve this problem and make better performance?
if i change page pool should i got a different ratio btw storage and programs memory other than 181.47/336.93, i changed all 4mb, 6mb and 12 mb and readings stay the same. should they not change?

any help please

Q: What is pagepool?
A: Page pool is an area of RAM which is set aside to hold the next block of code the processor is likely to need to execute. It prefetches this from ROM as it executes the program. If the next step of the program needs something that's not in the page pool, the processor goes to the ROM to get it. ROM access is slower than RAM access. So generally, as you increase the page pool size, the chances of the required code being in the page pool increases and speed increases. There is a limit beyond which you won't see any increase in performance.

thanks gianton for the link, but really it's not what i want, if someone just can give me answers on each queston will be very helpfull.
thanks again for any help
