Well, according to the atricle, both Nvidia and MSI were quite willing to disclose this information, but it was of those "don't tell until someone says something" type of issues. Most OEM builder stick a single stick in of the cheapest POS they can find, so it doesn't affect them. Most people in the real world wouldn't be able to see a difference if they added a stick themselves at a later time into the "superstability" causing DIMM. So, the minority of us (or, have we become the majority) won't notice this, and in cases that the article posted, you really wouldn't see the difference in the FPS for Quake. But, it would kill your Sandra, 3DMark2001, and benchmarking programs. And, also the article mentioned that there was a reference to this issue buried deep within the MSI manual. That's why, even though I knew how, I read my Asus A7A266 manual, and I found some little bits here and there myself. Anywho, it's not really a platform killer, unless you need all three DIMM slots, which either means you're running a server of some type (in which case, this probably isn't the board for you anyway), or you have small capacity sticks, which can be remedied through the purchase of cheap DDR right now. Me, I have 512MB, more than enough (I think at most, I am using ~300MB) for most home gamers right now. So, it's really not that big of a deal... right now. The test will be to see Nvidia's top-notch (self-proclaimed) R&D and QA do their job and give credibility to Nvidia's entrance into the chipset business.
