Enable 32-bit Ubuntu to support 4 GB memory

Let 32-bit Ubuntu support methods that exceed 4G memory-general Linux technology-Linux technology and application information. The following is a detailed description. 32-bit Ubuntu supports a large memory size larger than 4 GB

Currently, 32-bit Ubuntu only supports 4 GB memory. The solution is to use the server kernel:

Sudo apt-get install linux-restricted-modules-server

Sudo apt-get install linux-headers-server

Sudo apt-get install linux-image-server linux-server

Last restart

-----

Based on Different kernel versions, it may be:

Sudo apt-get install linux-restricted-modules-2.6.27-7-server

Sudo apt-get install linux-headers-server

Sudo apt-get install linux-image-server linux-server




32-bit process (general process, do not use AWE (Address processing wing Extension, Address window Extension) API set) Maximum use 3G


Note:

Install the server's kernel. A 32-bit system can use 4 GB or more memory, up to 64 GB. The premise is that the motherboard supports

Note:

32-bit systems (XP, windows2003, and other MS32-bit systems, Ubuntu and other linux32-bit Systems) must be able to use 4G memory, all of which adopt the memory re ing technology. The main board and system support is required.

If you disable the BIOS re- ing function, the system will not be able to use 4G memory, which may only reach 3.5G.

Note.

32-bit system, after the memory ing function is enabled, the system will not be able to use the sleep function (sleep is different from the Standby function ).
