Dual channel memory and 3 RAM sticks

[mrthuvi]

So i know that my motherboard supports dual channel memory (B75 chipset). What happen if i put 3 identical RAM sticks in it? Will it dual channel 2 sticks and leave the last stick alone?

I believe the sticks will switch from dual channel and run single channel instead.

It will have to be 2 or 4 sticks to run in dual channel.

Hmm. I think it will work but will not work as well as if it was supported. But i havent done this so it might go single channel so its sorta a waste just get another one.

My friend has 2x2GB. 4GB is a little not enough. 6GB is enough RAM for everything. But if adding another stick decreases the performance, i'll advise him to get another 2x2GB.

I think its what you say. 2 of them will run in dual channel and the other one alone. Im not sure what happens with performance.

If you put 3 sticks in a dual channel system, it will run in single channel mode, which will significantly reduce their performance. Just run 2 sticks.

Like other have said 3 sticks will make it run in single channel mode.

On paper this should cut the performance in half, in real life there will still be a big difference, so you should stick with 2 stick until you can get 2 more.

It will work in single channel, for dual channel you need either two or four sticks.

Thanks for your replies. :)  I'll told him to get 2 more sticks.

Or he can buy one more 2gb stick and save some monies.

 

edit: Hope it's not too late. Also make sure the RAM speed and timings are similar or better.
