32-bit windows, easy to play with 4 GB memory

Although the 4 GB physical memory in a 32-bit Windows XP or Vista operating system cannot be fully recognized, we can use the small ramdisk software, converts unrecognized memory space into hard disk space to make full use of 4 GB physical memory.

After two 2 GB Kingston DDR2 800 memories are installed, open the memset software and you can see that the 4 GB memory runs well in the dual-channel mode, so as to ensure the optimal performance improvement of the system.

1. Install the ramdisk driver

The new version of ramdisk software relies entirely on the gavotte version of ramdisk driver to take advantage of the memory space that 32-bit Windows cannot recognize. Download the ramdisk package, decompress it, and copy it to the D:/ramdisk directory. Open "Control Panel-add Hardware", select "Add new hardware device", manually install hardware, select ramdisk in the hardware list, and then select "disk installation ", in the driver dialog box, select the rramdisk under the D:/ramdisk directory. INF. After the installation is correct, the ramdisk icon appears in the Device Manager.

2. Enable the PAE mode for Windows OS

PAE is the so-called physical address extension. After this mode is enabled, a 32-bit Windows system can recognize physical memory of 4 GB or above on the hardware layer. The method for enabling this mode is very simple. You only need to double-click the ram4g. reg file in the D:/ramdisk directory, import the information to the registry, and restart the computer. After the PAE mode is enabled, the "physical address extension" appears under the memory capacity in the "my computer" attribute. (gemsea: in the absence of physical extension addresses, It is ram4g. reg does not work. You can add the boot option/PAE, my computer-> properties-> advanced-> startup and fault recovery-> edit, add/PAE at the end of the Windows startup Item of the text file. After the system is restarted, the words "physical address extension" will be displayed)

3. Correct BIOS settings

After completing the above software settings, you also need to set the "memory hole remapping" option in BIOS to "enable" (the specific option names may vary depending on the motherboard ). On my DFI 975x/g motherboard, if this option is enabled, only 2 GB physical memory can be recognized under xp. After this option is disabled, XP can recognize 3 GB physical memory. Only with this option enabled can the ramdisk software use the 2 GB memory that cannot be found by the XP system. (Gemsea: some boards do not have this configuration item, as long as the motherboard can recognize 4G memory, it can ignore this setting)

4. Software settings

After restarting the computer, run the ramdisk software, select "Install ramdisk" from the menu, and set the size and drive letter of the virtual disk in the drop-down menu on the left, set the virtual hard disk type to "fixed media" and click "Apply" at the bottom. If you want to detach a virtual disk, click "Remove ramdisk" to remove the virtual disk from the operating system.

3. Memory virtual hard disk

After ramdisk is used to convert the memory to a virtual hard disk partition, We Can format the partition based on our own needs. The NTFS format is generally used to achieve the best performance. Because it is a virtual partition of memory, the data read and write speed of this partition is very fast. I used the old disk read/write speed test software Atto disk benchmark v2.41 to compare the read/write speed between a general hard disk and a "memory hard disk". We can see that the maximum read Speed of Samsung sp2504c is only about 154 Mb/s, the maximum write speed is only about 186 Mb/s, while the "memory hard disk" reaches about 820 Mb/s and 1013 Mb/s respectively. This speed advantage is hard to find even the disk array.

We should make good use of this extremely high-speed "partition ". In Windows, some hard disk space is always set to virtual memory, which is used to store data temporarily unused in the memory to improve memory usage. We can transfer this part of the virtual memory page file to this partition, so that all data processing is carried out in the memory space, reducing hard disk read/write operations and greatly improving the system running speed.

First, go to the "System Properties> advanced" tab, set the virtual memory of drive C to "no page file", and set the partition space of the virtual hard disk as a page file. Of course, we can also set the cache space for downloading software such as thunder and Bt on the virtual hard disk partition created by ramdisk to achieve real lossless download. However, the data in this virtual partition will be completely lost after shutdown, so you should save the relevant data in time to avoid irreparable losses.

After completing the above operations, you will find that the XP startup speed is significantly improved. The XP progress bar rolling time decreases from 3.5 seconds to 2.1 seconds when the computer is started, while in normal software running, the read and write operations on the hard disk are also significantly reduced, and the 32-bit Windows operating system can be fully utilized in the 4 GB memory. Get started. ramdisk helps you make full use of the physical memory space to accelerate your operating system.
