Where to place new RAM

I am planning to install one module of 512 mbs of RAM adding to the two 128 mb sticks I have now. The two 128s are dual channel. Should the new stick be in open slot 3 or should it go in slot 1 since it is the largest module?

 

I think that with dual channel mem you have to install TWO mem cards at a time. Not one.

 

Try reading his post again, I think you'll find his 512 isn't a dual channel, only his two 128's

Anyway to answer your question, I don't think it really effects which slot you would put it in, but normally it's best to have your 512 in slot 1 and the two 128's in slots 2 & 3

 

Right. He has two 128's, and he wants to install ONE 512 .
I was under the impression that if your system utilizes dual channel memory, you have to install memory cards in PAIRS ONLY.
Thats how I was told to do it with my dual channel memory .
Am I wrong about this ?

 

Aah, I understand now, I think I mis-interperated your post FED UP. Please accept my apologies However, adding one stick of 512 should still work in most systemsif I remember correctly.

Please forgive me if I am wrong

 

No prob Momo.
Since there seems to be a bit of uncertainty here i found this :

maybe that will help .

 

I have a DEll dimension. I thought that by installing only one additional module I would lose dual channel mode but the system would still work.
