Rodger Johnson 1052770 Posted October 22, 2008 at 11:45 AM Posted October 22, 2008 at 11:45 AM 16 GiG'S Of RAM. Im going to get a new computer and im trying to get the best things out there. Im looking for 16 gigs of ram. Ive seen it done so Ive been looking and I really cant find anything other than up to 8. Im looking for DDR3 RAM... Does anyone know where I could get 16 gigs?

Erhan Atesoglu 1050499 Posted October 22, 2008 at 06:37 PM Posted October 22, 2008 at 06:37 PM Rodger: you can't put 16 gigs in a home PC. You'll need an Intel Xeon server if you want that much RAM. http://www.pond64.net Link to comment Share on other sites More sharing options...
Rodger Johnson 1052770 Posted October 22, 2008 at 08:38 PM Author Posted October 22, 2008 at 08:38 PM O wow then he must be lucky to have that computer lol he also had Twin Nvidia video cards at 1.5 gigs of memory each.... SO lets say i want Vista 64 Bit. How much ram can I get... I want this computer to last and getting a lot of ram will help me do that... AND get the best performance on FSX. Ram isnt the only thing that im building up on.. I just cant find big ram. Link to comment Share on other sites More sharing options...

Oliver Smith Posted October 23, 2008 at 01:46 PM Posted October 23, 2008 at 01:46 PM I've had 4Gigs of RAM now for over a year and I can't honestly say I've ever seen a OOM so imho 16Gigs, if even possible, is over the top. Link to comment Share on other sites More sharing options...

Mike Gaudet Posted October 23, 2008 at 04:01 PM Posted October 23, 2008 at 04:01 PM !!!Geek speaks!!! Memory Support and Windows Operating Systems Operating systems based on Microsoft Windows NT technologies have always provided applications with a flat 32-bit virtual address space that describes 4 gigabytes (GB) of virtual memory. The address space is usually split so that 2 GB of address space is directly accessible to the application and the other 2 GB is only accessible to the Windows executive software. The 32-bit versions of the Windows 2000 Advanced Server and Windows NT Server 4.0, Enterprise Edition, operating systems were the first versions of Windows to provide applications with a 3-GB flat virtual address space, with the kernel and executive components using only 1 GB. In response to customer requests, Microsoft has expanded the availability of this support to the 32-bit version of Windows XP Professional and all 32-bit versions of Windows Server 2003. Windows 2000 Memory Support. With Windows 2000 Professional and Server, the maximum amount of memory that can be supported is 4 GB (identical to Windows NT 4.0, as described later in this section). However, Windows 2000 Advanced Server supports 8 GB of physical RAM and Windows 2000 Datacenter Server supports 32 GB of physical RAM using the PAE feature of the IA-32 processor family, beginning with Intel Pentium Pro and later. Windows XP Professional and Windows Server 2003 Memory Support. The maximum amount of memory that can be supported on Windows XP Professional and Windows Server 2003 is also 4 GB. However, Windows Server 2003, Enterprise Edition supports 32 GB of physical RAM and Windows Server 2003, Datacenter Edition supports 64 GB of physical RAM using the PAE feature *. The virtual address space of processes and applications is still limited to 2 GB unless the /3GB switch is used in the Boot.ini file. When the physical RAM in the system exceeds 16 GB and the /3GB switch is used, the operating system will ignore the additional RAM until the /3GB switch is removed. This is because of the increased size of the kernel required to support more Page Table Entries. The [Mod - Happy Thoughts]umption is made that the administrator would rather not lose the /3GB functionality silently and automatically; therefore, this requires the administrator to explicitly change this setting. The /3GB switch allocates 3 GB of virtual address space to an application that uses IMAGE_FILE_LARGE_ADDRESS_AWARE in the process header. This switch allows applications to address 1 GB of additional virtual address space above 2 GB. The virtual address space of processes and applications is still limited to 2 GB, unless the /3GB switch is used in the Boot.ini file. The following example shows how to add the /3GB parameter in the Boot.ini file to enable application memory tuning: * Physical Address Extension. PAE is an Intel-provided memory address extension that enables support of up to 64 GB of physical memory for applications running on most 32-bit (IA-32) Intel Pentium Pro and later platforms. Support for PAE is provided under Windows 2000 and 32-bit versions of Windows XP and Windows Server 2003. 64-bit versions of Windows do not support PAE. PAE allows the most recent IA-32 processors to expand the number of bits that can be used to address physical memory from 32 bits to 36 bits through support in the host operating system for applications using the Address Windowing Extensions (AWE) application programming interface (API). Processes and Address Spaces All processes (e.g. application executables) running under 32 bit Windows gets virtual memory addresses (a Virtual Address Space) going from 0 to 4,294,967,295 (2*32-1 = 4 GB), no matter how much RAM is actually installed on the computer. In the default Windows OS configuration, 2 GB of this virtual address space are designated for each process’ private use and the other 2 GB are shared between all processes and the operating system. Normally, applications (e.g. Notepad, Word, Excel, Acrobat Reader) use only a small fraction of the 2GB of private address space. The operating system only [Mod - Happy Thoughts]igns RAM page frames to virtual memory pages that are in use. Physical Address Extension (PAE) is the feature of the Intel 32 bit architecture that expands the physical memory (RAM) address to 36 bits (see KB articles 268363 and 26198. PAE does not change the size of the virtual address space, which remains at 4 GB, just the amount of actual RAM that can be addressed by the processor. The translation between the 32 bit virtual memory address used by the code running in a process and the 36 bit RAM address is handled automatically and transparently by the computer hardware according to translation tables maintained by the operating system. Any virtual memory page (32 bit address) can be [Mod - Happy Thoughts]ociated with any physical RAM page (36 bit address).

There can be a large number of processes each with its own 2 GB of private virtual address space. When the memory in use by all the existing processes exceeds the amount of RAM available, the operating system will move pages (4 KB pieces) of one or more virtual address spaces to the computer’s hard disk, thus freeing that RAM frame for other uses.

Rodger Johnson 1052770 Posted October 23, 2008 at 08:41 PM Author Posted October 23, 2008 at 08:41 PM So that means that to be able to use a lot of ram im going to need a NOS? Is FSX even compatible to a NOS lol? What was the most ram you can use on windows vista 64 bit? -Rodger Link to comment Share on other sites More sharing options...
Rodger Johnson 1052770 Posted October 23, 2008 at 08:42 PM Author Posted October 23, 2008 at 08:42 PM O wait lol I found it So you move to 64-bit. With this comes some stiff driver requirements, but what do you get for RAM limitations with Vista 64-bit? Actually, it depends on what edition of Vista you are running: Home Basic is limited to 8GB, Home Premium is limited to 16GB and the other editions (Business, Enterprise and Ultimate) let you get all the way up to 128GB. I might get home premium lol. So back to the question anyone know where to get 16 gigs? -Rodger Link to comment Share on other sites More sharing options...
