diferent rams

[ITSmeJUICEE]

when i am mixing rams like 8gb ram and 16 gb ram does it have to be same brand? because my friend was trying to instal two diferent 8gb of ram and when he turned on pc it was black screen.

And I misread the tittle as different rants.

For different ram brands?  I think you can! I did on my current computer.  I think part of the trick is to make sure you turn off XMP. I thought I read on this forum that resetting the CMOS also helps.

See if this article helps:

Mixing RAM is more of an art than a science, there are times when it will just work, and there are times where you'll be bashing your head against a wall for 4 hours because it won't turn on ever. The only truly guaranteed way to mix RAM is for it to be the exact same, so same PCB revision and memory IC (neither of those are necessarily guaranteed with the same model number, though the same PCB is pretty common). If the PCB revision is different, you can sometimes run into weird compatibility issues (not often but sometimes), and it's even worse with different ICs. In my experience, with any two random sticks of the same capacity in the 3200 CL16-3600 CL18 speed bins, the compatibility is ~80% it just works at XMP with no issues, ~15% it works but XMP doesn't boot/is incredibly unstable, and ~5% the system won't even boot/is incredibly unstable. 

 

Definitely do a Clear CMOS, and if your system has a safe boot option (this is usually reserved for higher end boards though) try using that. Also make sure that each set of kits is in its own channel, so if you got two 2x8GB kits, have it as AABB in the board rather than ABAB.

Well said! When I did it, it just worked.

LTT has a video. That might help OP:
