dual channel configuration question

post #1 of 7
Thread Starter 
If a motherboard has 4 slots, and I have 3 sticks of ram (2 of which are matched), will the system still run that pair in dual channel? Or will it switch all of them to single channel?

For example, I have 1gb + 1gb in slot A & B, and just a single 512mb in slot C, slot D is empty, will that disable dual channel?

That pair will run in dual channel yes.

As long as they are in the correct slots.

I remember seeing a thread a while back.

And the answer was yes the 2 sticks will run in dual. But that single will only run single channel. Are you positive of this?

yes as the memory bus cant run dual and single channel together as the data would flow at different rates 64bit(single)vs128bit(dual)
post #7 of 7
3 sticks will switch the whole memory subsystem to single channel.
