It's exactly at 1MB, 5MB, etc, I captured the errors as following:

memtest crashed when it's doing own address test.
after examing the log file I found that the biggest address that it
displayed error is at 0x7d00000(125MB), any addresses above 125MB are ok.
the smallest address is at 0x20000(128KB).
