If the memory test results in 25 or less errors, then the RMT basic feature automatically fixes the issues. The test will indicate a pass result
since the defect(s) have been removed. If the memory test results in 26 - 50 errors, the RMT basic feature masks the defective memory
blocks and results in pass with no memory replacement requirement. If the memory test results in more than 50 errors, then the test is
stalled and the result indicates that memory module replacement is required.
