32-bit WIN7 system uses 4G memory method

Now the memory cabbage price, large memory has been a lot, want to use 4G memory method is less, install 64-bit system can, crack memory can, and then use the memory virtual hard disk, although Now 64-bit system has been a lot, but I still feel a bit uncomfortable, personal opinion (such as I look at two program files folder is not good)

After cracking the memory may cause system branch instability, there are There may be a blue screen;

(The first two methods I personally tried, the maximum available memory on my machine is 3.86G)

Although 64-bit systems are now a lot However, I still feel a bit uncomfortable, personal opinion (such as I look at two program files folder is not good)

32-bit Windows system theoretically available memory capacity is about 3.25G, I use the machine for Shenzhou Fine Shield K470 I5 D1; 32-bit system available memory is 2.9G (a part of the personal guess is divided into integrated graphics, although the small K on the set is shielded before leaving the factory)

First look Memory division, first Divided into unavailable, the system is shown as hardware reserved, the purpose is to use this part (available number is 4096-1036=3060)

Windows system will be built by default after C installation A cache file, generally the amount of system memory available

When the system is out of memory, the system will write some data in the memory to the cache file

OK, now the solution is coming

1, use the software to create a virtual hard disk in the memory. I use the software and version: Super Rabbit Virtual Disk Accelerator 1.6 (According to the test, the current operation is reliable, no need to set after the installation is completed)

2, set the cache file to the created virtual hard disk (this time it is best to cancel the cache file of other disk, because I can not determine the other disk has cache file when the system gives priority Which disk to write data)

3, get

Principle: When the memory is insufficient, the data is pressed to the cache file, and the cache file is on the virtual hard disk. The actual location of the virtual hard disk is memory, so save The speed is still the speed of the memory.

After testing, the memory used by the virtual hard disk is the memory of the hardware reserved area. Take the machine as an example: the virtual hard disk volume is 895M (I actually set 1024M when actually installing), in the first picture You can see that the available memory of the system is 3060M

(895+3060)/1024=3.865234375 (G)

The highest value of the available memory of the system has been reached

Note: Installation When setting 1024M, it will be automatically reduced to 895M after rebooting. Then restart the virtual disk size has not changed. It should be that some virtual hard disk is not available in the reserved part of the hardware, so it is speculated that it is reserved for the set.

People who watch PPS network TV can set the PPS cache file to the virtual hard disk. There are two advantages:

1, which can reduce the hard disk read and write (because PPS also In the upload)

2, PPS has a background process PPSwap.exe installed after the default boot, the cache file is set to the virtual disk and the cache file does not exist after booting, want to upload and find To things, good for students with less bandwidth (of course, you can manually Bundle the process)

In addition, the browser's cache directory can be set to the virtual hard disk, personally put the Firefox cache directory on the virtual disk, the province itself to clean up the cache file, and not often shut down The speed of the students who have read the pages will be much faster
