Will there be a problem if they're exactly the same just that 2 of the slots will be Samsung and the other 2 Kingston?
And please, do explain what this PC3-10600 thing is...
FlyinBird,
You shouldn't have any problem, just pair the like modules together. PC3 is just an ID for DDR3, 10600 is the clock speed and timing (CAS latency). I've paired diffent Make RAM with no problems.
