There is memtester: https://pyropus.ca./software/memtester/
But it can't test 100% of the RAM, only the free userspace area that it can
allocate. You should close down most apps and then give it (as a parameter) as
high amount as possible, without it getting killed by OOM. It could catch very
obvious faults, and it is a good "something to do" for now :) but for the
complete rigorous test you'll need the baremetal memtest86+.
