Computer Model ASUS K54HR Notebook Operating System Windows XP Professional Edition 32-bit SP3 (DirectX 9.0c) Processor Intel

Dear ASUS users, hello! According to your description, I suggest you refer to the following information:

According to the above information. At present, only the hard disk can be upgraded, and the hard disk can be replaced by SSD.

There is only one memory bank, and 4G is the largest memory supported, so it cannot be upgraded.

If the current hard disk speed can meet the needs, there is no need to upgrade.

However, the machine still recommends installing Windows 7 system. Tips: If 4G or more memory is installed in a 32-bit operating system, all memory will not be fully utilized due to the limitation of the system's own memory mapping access. If you want to fully recognize 4GB or more of memory, it is recommended that you install and use a 64-bit operating system.

Windows 7 driver is as follows:/notebooks/versatile _ performance/x54hr/# Download.
