System Information dialog box in Windows Vista shows less than expected system memory when the computer has 4 GB of RAM
Issue
If your computer has 4 gigabytes (GB) of random access memory (RAM), System Information dialog box Windows Vista shows less RAM.
For example, System Information dialog box shows 3120 megabytes (MB) of system memory when the computer has 4 GB installed (4096 MB) of memory.
Note. To open the System Information dialog box, follow these steps:
-
Press the button Start , enter the keyword System in the field Search and select System from the list Programs .
-
In the control panel, double-click the icon System .
-
From the Start menu , right-click the Computer icon and select Properties.
-
The chipset must support at least 8 GB of address space. This feature is supported by the following chipsets:
-
Intel 975X
-
Intel P965
-
Intel 955X for Socket 775
-
The CPU must support the x64 instruction set. This instruction set is supported by AMD64 and Intel EM64T processors.
-
The BIOS must support memory remapping. Using the memory reallocation feature, you can move the system memory segment previously occupied by the PCI (Peripheral Component Interconnect) configuration bus configuration space beyond the 4 GB address space. This feature must be enabled in the computer’s BIOS settings. See your computer’s documentation for information about enabling this feature.
Many computers intended for general users do not support the memory remapping feature. There is no standard term for this feature to use in documentation or BIOS setup. Therefore, you need to examine all available BIOS options to find out which ones allow you to enable the memory remapping feature. -
You must be using the x64 version of Windows Vista (64-bit).
To determine if your computer meets these requirements, contact your computer manufacturer.Note. If the amount of RAM physically installed on the computer is equal to the amount of address space supported by the chipset, the total amount of system memory available to the operating system will always be less than the amount of physical memory. Assume, for example, that your computer has an Intel 9 chipset75X supporting 8 GB of address space.
If you install 8 GB of RAM, the amount of system memory available to the operating system will be reduced due to the memory required for the PCI bus configuration. In this case, the PCI bus configuration will require approximately 200 MB to 1 GB of memory, and it is by this amount that the amount of memory available to the operating system will be reduced. The actual amount of available memory depends on the configuration. Additional information
Driver compatibility issues related to physical address extension mode
Data Execution Prevention (DEP) driver compatibility issues are typically caused by incompatibility with physical address extension mode.Note. Physical address extension mode should only be used on computers with processors that support DEP in hardware.
DEP can cause compatibility issues for any drivers that generate code or use real-time executable code generation technologies.
Many drivers that had similar problems have been fixed. Because DEP is always enabled for drivers that run on 64-bit versions of Windows, these drivers often have compatibility issues. However, there is no guarantee that all drivers have been updated to fix compatibility issues with physical address extension mode. However, the number of drivers using these technologies is small. Data Execution Prevention by itself usually does not cause driver compatibility issues. Driver compatibility issues occur primarily when using physical address extension mode on 32-bit computers. Physical address expansion mode allows the processor to use more than 4 GB of memory. The main difference between the memory paging schemes in physical address expansion mode and normal mode is the additional level of paging required in physical address expansion mode. Physical address extension mode uses three swap levels instead of two.
Some drivers may not load when PAE is enabled because the device may not support 64-bit addressing.
Also, when writing the driver, it may have been assumed that physical address extension mode requires more than 4 GB of memory. Such drivers are written with the expectation that physical address expansion mode will always use 64-bit addresses, so the driver or device will not be able to correctly interpret the address. Other drivers load in physical address extension mode but break system stability by attempting to directly modify system page element table (PTE) entries. In physical address extension mode, these drivers receive 64-bit page table entries instead of the expected 32-bit entries.
The most common problems when using drivers in physical address extension mode are direct memory access (DMA) and mapping register allocation. Many devices that support DMA (typically 32-bit adapters) cannot do 64-bit memory addressing. If the device is running in 32-bit mode, the entire range of physical addresses is available to it. In physical address extension mode, data can reside at addresses outside the 4 GB range.
Microsoft Windows 2000 Server and later versions of Windows use the DMA transaction double buffering system to ensure that devices with these limitations work. The Windows 2000 Server operating system and later versions of Windows do this by providing a 32-bit address specified in a mapping register. This allows the device to directly access memory at a 32-bit address. The kernel copies the memory to the 64-bit address provided to the driver. When physical address extension mode is disabled, drivers for 32-bit devices do not require system memory to be allocated to their display registers. This means that double buffering is not needed because all devices and drivers are in the 32-bit address range. Testing drivers for 32-bit devices on computers with 64-bit processors has shown that drivers tested by customers that use direct memory access usually rely on an unlimited number of display registers.

Is 8 GB of RAM enough on a Windows computer? path. We’ve come a long way from an era when we were happy about having 8GB of RAM to a time when a power user might get frustrated with it. The year is 2022, and many laptops are still being released with configurations equipped with 8 GB of RAM.
As your day-to-day applications become more powerful and provide better functionality, they also require more resources. You may have heard experts say that 8 GB of RAM on your PC is enough if you are a regular user. But this is becoming a thing of the past, since all over the world everyone uses applications that are demanding on resources.
Is 8 GB of RAM sufficient on a Windows PC or laptop?
Short answer: not really. If you don’t know what RAM is and what it’s for, here’s a quick explanation. Computers (and other mobile devices) use random access memory (RAM for short) to temporarily store data needed to run the operating system and its applications.
If you use multiple applications, the RAM fills up quickly, leaving less space for additional applications to run, ultimately resulting in slower performance. In general, your system and installed applications will run slower due to numerous processes clogging system memory.
But I only use a few apps, so why should I care?
Speaking specifically about Windows, a few years ago the OS and its system processes did not take up a lot of memory by themselves. However, Windows is receiving more and more updates and is now running many processes that use a significant amount of memory.
For example, Windows 10 has had a common problem for some time now. The Antimalware Service Executable process, part of the Windows security system, takes up most of the RAM. Although this process is launched when Windows performs a real-time virus scan, it has a serious impact on system performance.
Consequently, other applications suffer when your operating system uses up most of your RAM.
But it’s not just Windows that’s to blame. You have probably heard talk about Google Chrome eating up your RAM. As of 2022, most browsers can quickly fill up your memory if you open more than a few tabs. Therefore, if you have multiple tabs open all the time, 8 GB of RAM won’t work for you. 8 GB RAM laptop users with AMD processors are the hardest hit
With today’s Ryzen processor-based laptops, you also get integrated AMD GPUs. «Well, what’s so special about them? Intel laptops also have integrated graphics.»
A feature of integrated graphics in AMD laptops is that it uses shared memory, which means that the GPU’s virtual memory is shared with the laptop’s actual RAM. Hence, AMD GPUs end up taking up some of your 8GB of RAM to work with. Combined with Windows’ high memory usage, users get very little RAM for applications.
Output
In short, 8 GB of RAM is not enough if you use more than a few browser tabs and other applications. Although, you might be fine if you don’t multitask on your computer.
