DDR3 triple channel requirements question!

post #1 of 6
Thread Starter 
If I have 3 x 2GB DDR3 ram modules installed in my system and want to add another 3 sticks of ram, do the additional 3 sticks have to have the same 2gb capacity as the first three sticks to maintain triple channel mode?

I don't think so, haven't tried it myself but i have seen redhat_ownage running a 3 x 2Gb kit with a 3 x 1Gb kit for 9Gb total memory. This was on 1366, I really know very little about 775.

This isn't for my system sorry to confuse, this is for a friends rig who has an i7 setup running DDR3. Thanks for the input anyway.

They don't have to be the same capacity, but I caution you from using different sticks. It *can* be done with success, but remember that memory chips have far more timings than just those most commonly published (CAS,RAS, etc). Finding different sticks that work well together and have the same voltage can be tough. If it were me, I'd just sell what I had and buy new, but mixing can be done.
