I think the real issue here is not so much capability, as in how much this problem will affect the majority of users, but credibility, as in, when will the next shoe drop? I like a lot of others am looking at this board as a possible ideal solution to my needs (which is more mainstream performance & stability/ease of setup/driver maintenance, with only occasional gaming needs). However, just like cars I am somewhat leery of rushing out to buy "the first model year" of a new design -- let alone a new maker. Finding out that there is such a problem isn't so bad, but finding out that they knew about it EVEN BEFORE ANY BOARDS WERE RELEASED (since it is in the MSI motherboard manual), yet they weren't making any effort to inform their customers of the problem (since the warning to not use the DIMM slot was buried in the manual, without explanation) -- coupled with continued delays from all the other manufacturers (weren't these supposed to be out by September, and here it is, already christmas), makes me wonder -- are there lots of other "features" not yet uncovered? I remember the first Hyundais got lots of favorable press when they came out. Even the Yugo <snort>.
Again, the nForce board appeals to me due partly to the ease of setup/driver maintenance. I wouldn have never thought to try the memory cards in all those different combinations, so it upsets me that, without someone else having exposed this "feature" I might have bought this board & configured it for reduced performance needlessly -- since I would be using two 256mb PC2100 sticks -- just because nVidia didn't want to draw attention to limitations. It's a lot like the Intel pentium FP bug a few years back ... it may not effect very many people, but those it will effect AUGHT TO BE TOLD.
