Hi, i do i check if my mbp ram is failing without open case? My mbp have been very lag lately and apps like iTunes, Safari and steam can freeze from time to time and some time i even have to force quit it and restart. Im not sure weather I'm experiencing kernel panic but there are time when I'm doing normal task, my mac will black out with instruction showing me to restart the mac. iStats also shows my memory's activity always full with 63mb free with only few apps opened and only 1.8 of rams is active and 1.8 of rams inactive. Is these the signs of bad ram? I did check system report but the report shows both ram is working fine. Is it ram or other things. Btw, i have 15' mid-2012 non-retina mbp with two 2gb ram. Thanks!

Apple HW test, or most linux distros have a HW test on them that you can select in the grub menu

RAM should be matched though computers are not a bad about it as they have been in the past it's still best practice.

Is there other test rather than Apple hw test , cause internet recovery is taking a long time as I have really bad internet speed in my dorm.
 
However if you actually have bad RAM it is far more likely to give a proper bad RAM symptom like 3 chimes on boot as it fails the self-test, in general "bad RAM" doesn't just make a machine "slow" as you describe. Likely you have a SW issue causing that - but you can check Activity Monitor to show you that.
