i thought that one needed to match IN PAIRS memory sticks for motherboards.
(I have an intel DZ77RE-75K with g.skill ripshawx 8G X 2 sticks 1600 9-9-9)
One went bad, so i'm running with 1 X 8G now, and this brings up some questions.
Gskill tech support replied: (but this confuses the situation)
Mixing memory kits, even of the same model number, may result in compatibility issue. G.SKILL will guarantee the compatibility for single memory kit only
1. If i get one warranty replacement stick, then it's not a kit any more. So what good is a replacement warranty for 1 of 2 sticks if this is true.
The following questions are Assuming there is some latitude WITH THE SAME MODEL #
2. Is there likely to be a performance difference btwn (same-speed sticks):
1 X 8G stick AND 2 X 4G sticks AND 4 X 2G sticks
3. With the 2X 8G pair back in place, is it beneficial (speed; other than just more RAM) to add a second pair but of 2 X 4G ?
(or does it REALLY need to match 2X 8G)
