`memcheck86` is included in most Linux LiveCDs (ok, let's start to call them live USB sticks?). It will stress-test the system DDR/SDRAM.

If you need to check external memory (GPU, IoT, etc) then there is some tools online.

Note that memtest86 doesn't test against Rowhammer like attacks probabilities.

You can also use some overclocking features in advanced motherboard to push the memory beyond factory settings and see how far it gets before it starts to misbehave.
