Look in your manual, my version 3 copy says, on page 4-17, that it has an option "DRAM Over 4G Remapping" that defaults to disabled. My machine only has a pair of 1GB sticks in it currently so I can't test it. Would like to know if I'd get 4GB instead of 3.5GB so could ya report back? -- John M. http://www.beau.org/~jmorris This post is 100% M$Free!
