为何 32 位 x86 系统上的 Windows 客户端版本会人为地将 RAM 限制为 4 GB？
答案当然是兼容性问题。这篇文章解释了为什么 32 位 x86 系统上的 Windows 客户端版本会人为地将可用 RAM 限制在 4 GB，原因在于需要确保与大量依赖 32 位地址空间的驱动程序、应用和硬件保持兼容。

The article explains that 32-bit Windows editions limit RAM to 4 GB due to the 32-bit memory address space (2^32 = 4 GB). Part of this address space is reserved for hardware devices (like PCI, BIOS, etc.), leaving less than 4 GB actually usable by the operating system. This is not an artificial cap but a hardware limitation of the 32-bit x86 architecture.
