System RAM memory is integral for the proper functioning of your OS and handling of your data, and confirming that it is at fault (or ruling it out) can save you many worries and help you with troubleshooting errors on your PC.
RAM chips consist of a large array of tightly packed memory cells, one for each bit of data. The vast majority of the intermittent failures are a result of interaction between these memory cells. Often writing a memory cell can cause one of the adjacent cells to be written with the same data. An effective memory test attempts to test for this condition. Therefore, an ideal strategy for testing memory would be the following:
- Write a cell with a zero.
- Write all of the adjacent cells with a one, one or more times.
- Check that the first cell still has a zero.
