looking for a method to test the ram on a linux sbc

[legacy]

so, I happen to have realized a made in home linux SBC, and I'd like to test if the ram is OK since I have manually soldered it on the PCB.
do you know, guys, a method to check how good it is?

I could implement a few lines of C (1), but before reinventing the wheel I know I'd better ask, so here I am 


(1) e.g. with a big malloc, and then doing pattern-check (address in address) inside the slice
may be a good idea?

You may get some ideas from http://www.memtest.org/

There is a program for Linux called 'memtester'.

If you can boot your system from a live CD/DVD (or probably USB) of most distros, they have memtest as a boot menu option.

If you can boot your system from a live CD/DVD

it's neither x86 nor arm, there is no CD/DVD for it 
But, I can use the kernel + the rootfs to test the ram.
