Memory speed improvement tips (1)

Many users want to upgrade their memory to speed up their own computers, but some users find that after upgrading the memory, the speed of the computer is slower. This is because the memory is large, and the sleep time is also longer. It's slow, in fact, we can set the registry, and reasonable allocation of memory space, you can get unexpected results. Let's take a look at the author's memory speed improvement skills.

First, modify the registry to play a large memory advantage Open the registry editor, find [HKEY_LOCAL_MACHINE\\System\\CurrentControlSet\\Control\\Session Manager\\Momory Management], modify some key values ​​in the right pane.

1, "LargeSystemCache" (starting a large system cache): Open a large memory space in memory for the pre-read operation of the disk file system. When the data requested by the program increases, Windows automatically reads ahead through the system cache, so that the program can get the required data as fast as possible. Since enabling this system buffer consumes more physical memory, the available physical memory that can be utilized by the program is reduced. Set its value to 1. In this way, the system cache is increased from 4MB to 8MB.

2, "SecondLevelDataCache" (improve cpu performance): CPU processing speed is much greater than the memory access speed, and memory is much faster than the hard disk. In this way, between the CPU and the memory, the performance bottleneck is formed between the memory and the disk. The previous "LargeSystemCache" is designed to alleviate the memory and disk bottleneck, and the CPU is also set to obtain the processed data quickly from the memory. A buffer mechanism L2 Cache (secondary cache). Adjusting this key value will enable Windows to better match the CPU's use of the caching mechanism to achieve higher data prefetch hit rates. It is recommended to set it to 512.

3. DisablePagingExecutive: Change its value to 1 (hexadecimal), which will force all programs and data to be forced to run in physical memory instead of using virtual memory. Obviously, when there is enough physical memory to complete the required tasks (such as 1GB or more), this will greatly improve the system performance. Enabling it for users with only 128MB or less of memory may be a disaster - the system makes frequent mistakes until it crashes.

4. "IOPageLockLimit": The input/output system is the channel for transferring data between the device and the microprocessor. When the buffer size is expanded, the data transfer will be smoother. In the same way, the size of the specific setting depends on the size of the physical memory and the number of running tasks. Generally speaking, if the memory has 64MB, the hexadecimal value of the double-byte key can be set to 400 (1MB), 800. (2MB) or 1000 (4MB) 128MB memory can be set to 1000 (4MB), 2000 (8MB) or 4000 (16MB); 256MB memory 4000 (16MB) or 8000 (32MB). Of course, if you have more memory, you can set it to 10000 (64MB) or more. When set to 0, Windows will automatically configure.

Second, using the virtual hard disk software RAMDisk Plus, this software is to divide a part of the memory as a disk partition, RAMDISK plus can also add multiple partitions, and then put some commonly used programs into it, so that It must be much faster.

1, some temporary folders are transferred to this partition, such as IE's temporary folder, which will greatly improve the speed of your browsing.

2, but after the memory is powered off, there is nothing inside, but Ramdisk plus provides the option to automatically save the shutdown, that is, you can save the contents of the virtual hard disk partition to the actual hard disk partition when you shut down. The place you specify, and then load back when booting, similar to the dormancy, but this will cause the shutdown and boot time to become very long, so it is recommended to only put temporary files on the virtual hard disk partition, anyway, the temporary file sooner or later It is to be emptied, and it is also saved on the ramdisk.

The above explanation explains the arrangement of the memory space, with

and the memory speed improvement technique for setting the registry, the running speed of the computer will definitely increase by one height.
