Problems solved by technology

[0005] At present, there are many testing methods for testing the memory ECC function, but most of them need to be tested under the computer system or under the BIOS environment, which is not very convenient to operate.

Embodiment Construction

[0029] Attached below figure 1 An easy-to-operate memory ECC function test method provided by the present invention is described in detail below.

[0030] The test method of this a kind of memory ECC function, its concrete test steps are as follows:

[0031] 1. Install the Linux operating system on the server, and lead out the lead wire of the data bit of the DIM slot of the server memory;

[0032] 2. Start the server to the operating system and start installing the memory detection software. The memory detection software is memtest software. The installation process is as follows:

[0033] 1. Decompress tar xjvf memtest.tar.bz2;

[0034] 2. To patch, a script is provided in the compressed package to install the patch:

[0035] cd memtest

[0036] sh patch.sh

[0037] The script will prompt you to enter the directory where the Linux source code is located. After entering the correct location, the script will automatically complete the installation of the patch. You can us...

Abstract

The invention provides a method for testing an error checking and correcting (ECC) function of a memory and belongs to a memory detection and error correction method of a computer server. The method comprises the following steps of: leading a wire for pulling down the level on one of memory data bit lines of a memory board; starting a system and running a memory detection tool in an expandable firmware interface (EFI) shell; when a memory is detected, grounding a lead wire in the second step to pull down a data bit and simulating to produce a bit data error; and displaying a memory error and error correction information by detection software. Compared with the prior art, the method for testing the ECC function of the memory has the advantages that: the error produced by the memory can be checked accurately and conveniently, the frequency of producing the error can be controlled and the produced error information can be checked through software; and the method has good popularization and use values.

Description

technical field [0001] The invention relates to a memory detection and error correction method of a computer server, in particular to a method for testing the ECC function of the memory. Background technique [0002] Memory is an electronic device, and errors will inevitably occur during its working process. For users with high stability requirements, memory errors may cause fatal problems. Memory errors can also be divided into hard errors and Soft errors: hardware errors are caused by hardware damage or defects, so the data is always incorrect and such errors cannot be corrected; soft errors occur randomly, such as sudden electronic interference near the memory and other factors may cause A memory soft error occurred. [0003] In order to detect and correct memory errors, servers in the prior art are mainly implemented with ECC (Error Checking and Correcting, error checking and correcting) memory. ECC memory is error correction memory. The functions are generally used in...
