Mixing dual channel RAMs.

[Neverluke]

So, the question is simple. I bought a 16Gb dual channel kit from GSkill for my pc. I used to have another Kingston dual channel kit, but it was a 8Gb one. Of course I`m with the former kit right now, but I still have the last one, and my motherboard has 4 RAM slots, so I tought, why shouldn`t I plug the four of them, all together, for a total of 24Gb?

Assuming that I insert them in dual channel config for each kit, what are your thoughts about performance? Like, gaming and normal usage perfomance. I alredy know it will work, It`s just that it seems even a little bizzare to me, so I dont mind asking first.

Thanks for any answer!

usualy we do not mix ram the other thing you have to check is the voltage they work and cas settings they use also you could put 1 new stick in first slot and one old in second then do the same for 3 and 4 .

Voltage is the same for both kits, speed can be managed by BIOS settings, CAS are differente for both pairs of course, and as I said, I`m respecting the channels, pairing each RAM with their equal.
So, the question still remains. Would it be any decrease in performance?

Thanks!

It depends if they can work together at all. If so, then you can test for the highest frequency, but right now we haven't a clue as to whether they can even boot up together.

Okey, I`ll test it! Thanks!

So, there can be compatibility isues between RAMs, even tough they share the same DDR type? What can cause this isues?

use cpu-z to check them on spd thab and them put jedec settings manualy in bios to the one the are most near from both set old and new after check on memory tab with cpu-z for the result .

Yes, even the same exact model RAM can have problems. RAM is not a mass produced item so slight variances can cause compatibility differences. This is more sensitive when it comes to high frequency RAM, but issues can still happen with standard frequency RAM. For this reason, it is always best to use a single complete kit of RAM for optimal results.
