I run 32bit system, not 64. Lappy, not desktop. Nothing wrong, except windows 8 (!)
My 7 is more faster than your 8 for sure...

Not even close sheesh... Why did you install 32bit?

Why I Installed 32 bit is not the point and this was already explained
 
BUT here you will see why 64 is crap, here you can activate all memory you want with this bootkit. I DID IT !

I don't see why "64 is crap," or why, if you have an x64 compatible CPU you wouldn't just install that...  but whatever.

K, relatively new to this, but tried nevertheless. I run a 32bit  version of Windows 7, and want this due to the fact that it'll take me ages to reinstall everything I have on a clean x64 version (also, asides from memory, have no actual need for x64).
I followed the instructions start to end and encountered no errors whatsoever. I rebooted, chose the "All memory" option, and it seems to work fine (shows all 4GB now and though the lower right corner of the screen says "Test Mode Win7").
However, after a relatively short period of time, with little to no action on my part, I get BSODs stating either 'page fault in nonpage area' or 'PFN list corrupt'.
Memory was tested and is fine, and I have new drivers for everything as far as I can tell. Any ideas what might be screwing this up? Really want this to work...
 
Thanks in advance!

Why would I bother going backwards? Gosh then holy cow!!!! 16 bit or 8 bit must be FANTASTIC! Further your link does even hint using 64bit is crap or inferior. Because obviously native 64bit IS SUPERIOR. That's great you can use someone else's boot kit to trick 32 bit Windows into running SOME mode of 64 bit. Personally I'd just use the real deal and install 64 bit. Go ahead, make your day, use the real deal!

Probably a driver issue being mapped into the wrong or unexpected memory space. You can probably narrow it down by booting into safe mode and going into device manager and disable individual hardware and reboot. Start with say, your audio device, then Ethernet, etc etc until you find the one that doesn't cause a BSOD.

@HeavyHemi: Well, gave it a shot, but nothing seemed to make it more stable. Updated pretty much everything that I could find as well, but still getting BSODs.
Would that link posted by mikele59 (the one for downloading a bootkit) be of any use in this case? Or would that basically leave me in the same place that I'm already at with my unstable full memory "Test Mode"?

Sorry if this is old but, when i did this (after some common sense work around some problems) my computer's resolution is limited to 1600*1200 when the actual maximum is 1920*1080.  
How the heck do i fix this?
Oh and btw my computer specs:
Amd Phennom 2 x6 1055t @2.8 ghz
8gb ram (this is why i did this)
Amd radeon 4250 biult in graphics
Asus m4a88td-m

Glad I didnt have to necro this thread, as its easily the best thread on this subject out there.
Anyhoo, like that one guy a fair while back in this thread, I've hit a snag at the;
 
editbin /release ntkl64g.exe
 
command. I get the same error as well:
 
LINK : fatal error LNK1104: cannot open file 'ntkl64g.exe'
 
I'm currently running Windows 7 (32x, but I guess thats obvious), and any help would be very much appreciated. Thanks!
 
p.s. Oh, and another question. If I've exited out of command prompt at this stage (I cant wait all night for a response, no offense) will I have to re-input all the commands?

Wouldn't it just make sense to install a x64 OS in the first place?

I highly recommend anyone using 4GB or more of total system memory go to 64 bit Windows but for anyone who wishes to stay with 32 bit the original OP's solution is still a good one and in fact it's the only solution for 32 bit.
 
You can always back up your personal files and make a fresh 64 bit install and restore your personal files. However as previously mentioned you would have to reinstall your programs but it isn't that much work and you can spread the workload for that over several days.

this is useful but you just tried it on VMware, is it really work in a real windows 7 ?
and can you give me the link for visual studio 2008 edition because the version you gave is the 2012 edition, I can't find the 2008 version.
I really want to to try this, no I don't want to try, I have to do this, it's just a waste if I have 4GB ram on windows 7 32bit but it just read 3.15gb, so please help me

Why do you need 2008?  You can use 2012, it's the same thing.

well, it said 2008 version will work, so I just want to follow the instruction, because it's a little bit dangerous to try something like this, okay, thanks, I'll try it now

makecert.exe comes with both Visual Studio and the Windows SDK, just download and install.

I don't see why not but it is far easier just to migrate to Windows XP Pro 64 bit

This guide was not explicitly wrote for Windows XP in mind.  However, it's possible that it will indeed work.  Your hex strings will be different - the ones provided are for Vista/7.

Update your installation completely (SP3) and try again.

I have SP3 and those hex values are not there, I was wondering that maybe I should use SP1 instead :)
 
but if the values are different and they are nowhere to be found, what should I do ?
