First download CPU-Z and go to SPD tab, now there will show JDEC #5 and probably XMP, look for higher speed and write those numbers down or take picture.
(if you can take screenshot it would be helpfull)
(in bios)In my favourites there should be DRAM frequency and DRAM voltage, select DRAM frequency to max probably as rated as in CPU-Z tab which is 2133 or higher, depends from your RAM, and last info is voltage set 1.35V should be good, but does your ram have heatsinks?(This is crucial info)
Now the timings as i explained up you should increase by 1, except tRC (that makes my every time crash).
After you boot AIDA64 should be good for that, go to "Tools" tab and select "Stability test" uncheck everything except Stress system memory, now im not sure for how long but i ran 15min. In aida you have cache and memory speed test and you can benchmark memory speed.
But if you wanna real way to test Ram stability download Memtest86 and make bootable drive, it should run 7 or 8 passes.
This is far as i know how to do it.
If it doesn't boot just reset CMOS or it will boot after 2 or 3 tries as it is default in bios by boot faulire guard.
Only thing that can kill your ram is heat or voltage.
Max rated and unsafe voltage should be 1.5V but DONT GO FOR THAT!
