Memtest86 Pro 10.6.1000 instal the new version for iphone

The answer to the question regarding the working state of the installed memory modules comes fast with Memtest86 and that is what matters the most besides the certainty of the verdict. There are many good approaches for testing memory. However, many tests simply throw some patterns at memory without much thought or knowledge of memory architecture or how errors can best be detected. This works fine for hard memory failures but does little to find intermittent errors. RAM chips consist of a large array of tightly packed memory cells, one for each bit of data.īIOS based memory tests are useless for finding intermittent memory errors. 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.

Therefore, an ideal strategy for testing memory would be the following An effective memory test attempts to test for this condition.

Write all of the adjacent cells with a one, one or more times.Ĭheck that the first cell still has a zero. It should be obvious that this strategy requires an exact knowledge of how the memory cells are laid out on the chip. In addition there are a never ending number of possible chip layouts for different chip types and manufacturers making this strategy impractical.

However, there are testing algorithms that can approximate this ideal and MemTest86does just this.Īdded new config file parameter, 'MAXCPUS', for setting the maximum number of CPU logical cores used for testing.

By default, this value is 256 (Pro Edition) and 16 (Free Version).
