This article introduces the knowledge of "how to use Memtester for memory stress testing on the server of Linux system". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Recently, to test the overall performance of a machine, I searched google and found that this gadget can be used for stress testing of memory. Memtester mainly captures memory errors and has been in very high or low bad bits, and its main test items are random values, XOR comparisons, subtraction, multiplication, division, and or operations, and so on. Given the size and number of test memory, the above project can be tested on the existing memory of the system.

1 download

The code is as follows:

Wget http://pyropus.ca/software/memtester/old-versions/memtester-4.2.2.tar.gz

2 installation

The code is as follows:

Tar zxvf memtester-4.2.2.tar.gz

Cd memtester-4.2.2

Make & & make install

3 introduction of parameters

Memtester [- p PHYSADDR] [ITERATIONS]

MEMORY applies for the amount of test memory. Default is megabytes (megabytes), or it can be B K M G.

The number of ITERATIONS tests. The default is unlimited.

4 start the test, apply for 10 MB of memory, and test once, as shown below:

5 trial experience

I mainly want to stress test the memory. The above is just a trial. You can apply for large memory and put it into the background for unlimited testing.

The code is as follows:

Nohup memtester 2G > / tmp/memtest.log &
