Want to test integrity and global performances of no-ECC memory chips If it's not supported, you might be able to benchmark using stream: You might be able to compile it for arm, if supported: RamSpeed is the only multiplatform memory benchmark tool I'm aware of. What are the best possible ways to benchmark RAM (no-ECC) under linux I don't know if it manages your particular hardware, but you probably could give it a try anyway. Now you may run various tests, for instance check that both temp files are identical, directly or running md5sum, sha1sum, etc: # time cmp /mnt/test1/test /mnt/test2/testĪbout temperature monitoring, I know only of lm-sensors. You can check that your memory is actually quite full: # free # dd if=/dev/zero of=/mnt/test2/test bs=1Mĭd: écriture de `/mnt/test2/test': Aucun espace disponible sur le périphériqueġ28802816 octets (129 MB) copiés, 5,78563 seconde, 22,3 MB/s Now fill the tmpfs with dd: # dd if=/dev/zero of=/mnt/test1/test bs=1Mĭd: écriture de `/mnt/test1/test': Aucun espace disponible sur le périphériqueġ28802816 octets (129 MB) copiés, 1,81943 seconde, 70,8 MB/s Here's the way I sometimes test ram: first mount two tmpfs (by default tmpfs is half the ram): # mount -t tmpfs /mnt/test1 /mnt/test1 Thanks for you answers, I'll continue to investigate I'll continue to check tools that run directly under linux without too big dependencies, after I'll maybe give a try to solutions like stresslinux, memtest, stress for fedora.
