memtester [-p PHYSADDR [-d DEVICE]] [-m TESTMASK] <MEMORY>[k|M|G] [ITERATIONS]
Options: -p PHYSADDR tells memtester to test a specific region of memory starting at physical address PHYSADDR (given in hex), by mmaping a device specified by the -d option (below, or /dev/mem by default).
-d DEVICE a device to mmap
