Windows Vista 32 Bit Somehow Recognizes 8gb Ram

For the ordinary kernel, the license value for the maximum physical address is the same as for the total amount of memory, but the PAE kernel has a separate license value, The 32-bit editions of Windows Vista and Windows 7 all contain code for using physical memory above 4GB. Unfortunately, there's no hard and fast rule that allows you to know with certainty. Then we found this: http://msdn.microsoft.com/en-us/library/ms178067.aspx there it says "Under Windows Server 2003, dynamic AWE memory is supported on servers with less physical memory than the configured virtual memory limit. http://hosting3.net/windows-vista/windows-vista-blue-screen-moved-from-vista-7.html

With the advent of better GP-GPU performance and being programmable these days, that will take the major hurdles for your machine and allow you a comfortable range of detail while not Reply Doug E. Why is the number so high here? Because of that all I become suspicious that microsoft isn't able to fix it ! http://www.sevenforums.com/general-discussion/340115-pc-only-recognizes-8gb-16-gb-ram.html

Indeed, since Microsoft is apparently happy to license the use of physical memory above 4GB on 32-bit Windows Vista SP1 when rebadged as Windows Server 2008, I would be astonished if With this option, PAE is not available.) Windows XP 32bit is not able to manage the whole physical memory, altough PAE is working as you can see in the following screenshots: These each have four kernels: NTOSKRNL.EXE, single-processor, without PAE; NTKRNLMP.EXE, multi-processor, without PAE; NTKRNLPA.EXE, single-processor, with PAE; NTKRPAMP.EXE, multi-processor, with PAE. Hardware & Devices Why a new installation recognizes my name?Well i did a slow format to install windows 7 again in the same Hard Disk, the surprise is when after do

After "retiring" in 2001, Leo started Ask Leo! And no you (MS) has the balls to stat, that you want to protect the costumer by disallow to make his own decision? Most of the sites require Flash Player to view the products. Except for that, I cannot help you choose one over another.

VMWARE ALL YOUR MEMORY IN BITE SIZES A last resort could involve running something like 64bot Linux with 64bit VMware host. I think you will find that your graphics card is using both onboard memory and shared memory. My System Specs Computer type PC/Desktop System Manufacturer/Model Number Custom Build OS Win 7 Ultimate 64 bit CPU Intel i7-3930K Motherboard ASUS P9X79 WS Memory Kingston HyperX Genesis 32GB Kit (8x4GB http://ask-leo.com/why_doesnt_windows_show_all_4gigabytes_of_memory_i_have_installed.html As someone has already pointed out a 64-bit Vista Ultimate can address several times more memory than Windows Server 2008 standard 32-bit or 63-bit.

stick with xp until windows 7 comes out Reply sss2 says: February 14, 2008 at 12:30 pm yeah my PC with 2 OS (Vista 32-bit and XP sp2) just detected 3,5GB They are also the sort of driver to which Microsoft will not give a digital signature unless the driver passes Microsoft’s testing at the Windows Hardware Quality Labs (WHQL). Log in with your credentials or Create an account Sign in Remember me Lost your password? Is it worth re-installing a 64-bit OS to get extra RAM?

So you will lose functinality of 512 megs of your System Ram, because the OS will see the 512 megs of your video memory. https://4sysops.com/archives/why-windows-vista-only-sees-3gb-memory-in-a-pc-with-4gb-ram-and-how-vista-sp1-fools-its-users/ Reply Shresel says: April 17, 2007 at 3:15 pm But how come, that Vista only shows 2GB of RAM, even with PAE enabled? XP SP2 introduced a change such that only the bottom 32 bits of physical memory will ever be used, even if that means some memory will not be used. (This is Reply Pavan says: May 21, 2007 at 10:17 am Thanks for detailed information.

My System Specs Computer type PC/Desktop System Manufacturer/Model Number Built them myself, Science Experiments ! More about the author then i installed win xp 64 bit pro and it shud show 4 gb ram as its 64 bit os but it also shows 3.25 gb of ram. At least not yet. 64bit Windows. I do not mean to recommend this method of testing.

My only hand in these offerings is that they draw from what I have written here. I am shocked that someone writes an article about this in the public.

It doesn’t tell you which addresses actually do have RAM (or ROM, for that matter). Note in particular that Test Mode is not Safe Mode. Originally, there was no need to even consider support for more than 4GB on clients because that amount of memory was rare, even on servers.

If fear of this is an argument against using memory above 4GB, then it is just as much an argument against enabling DEP.

But I can’t swear that everything works correctly in every detail and I especially can’t answer for behaviour that is not in the Windows code. Having a pagefile doesn't change the virtual address space that the OS is programmed to use. @David Willmore - PAE is more than just expanding the amount of address space. The trick is called memory remapping. Usually when you see a chunk of memory missing in Windows like that, it's because the system has reserved that memory for video memory, or something like that.

I hope this helps clarify it for you. Is there any way to access or use the lost 0.75 MB in any way? The original design of the x86 32-bit protected mode only provided access to 32-bit addresses, so PAE (Physical Address Extensions) mode was created to allow access to 36-bit addresses. http://hosting3.net/windows-vista/windows-vista-doesn-t-look-like-vista.html Persistent Test Mode To set up a persistent test, use the BCDEDIT utility to write the options into the BCD store.

I would have gone with 64 bit but the main software I use for my business doesn't support 64bit. With only a few highly contrived exceptions, any errors with a 32-bit driver’s handling of 64-bit physical addresses, e.g., to discard the high 32 bits, would be as much in error This may help you find the patch sites even if you have a different build (such as you may have picked up from Windows Update). It was disclosed eventually.

Hardware & Devices Win 7 recognizes 8GBs of RAMWell, my RC finally expired yesterday and I was getting the dreaded pop-up to upgrade. I run Vista64 with a total of 8GB, shows 3.83GB. You don’t have to stand for long in a computer shop to hear a sales assistant talk of 4GB as some sort of limit for 32-bit operating systems, and it won’t However, to avoid potential driver compatibility issues, the 32-bit versions of Windows Vista limit the total available memory to 3.12 GB."Well, Microsoft should know about the limits of Vista, right?

I have a general question for you- I had the oppurtunity to read your Internal books in tandem with William Stallings Operating System book- both terrifc reads and great when paired You can have the two together: while “Windows Vista Using All My Memory” is selected at the boot menu, just press F8 to open the Advanced Boot Options Menu and then Windows 2000 required that the available physical memory exceed the virtual memory in order to enable AWE memory." Based upon this description we decided to do the normal 2.5x RAM sized Very soon after this article’s first publication at this website, other people and teams started to offer programs that automate the steps given below and spare you from needing separate programming

It typically includes video memory of its own. For the record, I can't use the meminfo utility you suggest because it requires Vista or later. Since patching the kernel will almost certainly have invalidated this stored checksum, you need to reset it. Each sequence calls the undocumented function ZwQueryLicenseValue and then tests for failure or for whether the data that has been read for the value is zero.

There is no such limitation in XP 32-bit. During XP SP2 testing the driver problems were discovered and so the change was made then. You might also be able to access more memory by minimizing the hardware installed (each hardware component reserves some address space, possibly reducing the address space accessible to Windows).
