Since you didn't tell us anything about the spec, use the one that work better on your system
That may not be the best answer considering 1 may be 1600mhz and 8gb's but seem to run better than an 1866mhz 16 or 32gb set when the latter set would clearly be better. We need more information on the kits of ram you have.
