You are absolutely correct in that it is a function of the motherboard
to utilize the dual channel. I was unclear on that. But the RAM still
has to spec out the same in order to accomplish this. Very tight
tolerances are required for problem-free operation. I have tried
running a couple of dissimilar sticks in my Abit AN8 and was subject
to random reboots. 2 DDR400 sticks with the same chip configuration,
in perfect condition, would only run in 64 bit mode.
The RAM was tested by me one stick at a time and came up individually
perfect.
I purchased matched 1 gig sticks and they run flawlessly in 128 bit
mode. Buying matched pairs is the only way to go. Now, if you believe
me to be incorrect, give me some cites, I am always willing to learn.
Here is a link to a whitepaper on the subject.
