Thanks for clarifying. Can you tell me what other boards are out >there that don't exhibit this (cough) feature, or if they do, at what >RAM capacity do they exhibit it? (just wanting to avoid the same sort of >mistake again). You have to check each board you're looking at to see which "glue" chipset it uses. Intel makes several, as well as a few other manufacturers. Take a look at: http://www.anandtech.com/chipset.html Unix systems measure "uptime" in years, Winblows measures it in minutes.
