FAQ-toImportant notice on installing Windows XP 32-bit version
If you install Win XP 32-bit version OS, the limitation of this OS version is that it may reserve a certain amount of memory space for system devices. We recommend that you install less than 3GB system memory if you would like to work on WinXP 32-bit version OS. The excess memory installation will not cause any user problem, but it will not give users the benefit of manipulating this excess memory space.

I have install total 4GB memory on my motherboard. However, it can only recognize around 3.1GB or less. My friend's SLI board even less than 3GB. What's up? How should I do to recognize 4GB totally?
Answer
If you installed total 4GB memory, the system will detect less than 4GB of total memory because of address space allocation for other critical functions, such as:
- System BIOS (including motherboard, add-on cards, etc..)
- Motherboards resources
- Memory mapped I/O
- configuration for AGP/PCI-Ex/PCI
- Other memory allocations for PCI devices
Different onboard devices and different add-on cards (devices) will result of different total memory size.
e.g. more PCI cards installed will require more memory resources, resulting of less memory free for other uses.
On a SLI system, since PCI-Ex graphic cards will occupy around 256MB, another 256MB will be occupied after you install a 2nd PCI-Ex graphic card. Hence, 2.75GB memory left only if two SLI cards installed on A8N-SLI Premium while 3.0GB memory left with one graphic card without other add-on devices.
This limitation applies to most chipsets & Windows XP 32-bit version operating system.
If you install Windows XP 32-bit version operating system, we recommend that you install less than 3GB of total memory. If more than 3GB memory is required for your system, then below two conditions must be met:
1. The memory controller which supports memory swap functionality is used. The latest chipsets like Intel 975X, 955X, Nvidia NF4 SLI Intel Edition, Nvidia NF4 SLI X16, and AMD K8 CPU architecture can support the memory swap function.
2. Windows XP Pro X64 Ed. (64-bit) or other OS which can address more than 4GB memory.DESKTOP: MONITOR: DELL P2417H | CPU: Intel i5 6400 @2,7ghz | RAM: 4x8GB DDR4 | GPU: Sapphire Nitro+ RX580 8GB | HDD: NVME Samsung 960 EVO 256GB , Samsung 860 EVO 500GB | UPS: Eaton E5 1500VA | Mouse: GM-M6800| Keyboard: A4Tech | Case: Coolermaster HAF-XB | Notebook: ASUS K52JK SX001D 15,6" Fedora 30
