Don't drivers only load when Windows loads. Memtest uns before that. I can't find the link to new drivers. Intel list two -one only for advanced users- http://downloadcenter.intel.com/filter_results.aspx?strTypes=all&ProductID=816&OSF ullName=Windows*+XP+Home+Edition&lang=eng&strOSs=4 5&submit=Go%21

Does it matter which one? Are these the latest? 6-02-08 seems pretty up to date to me.

I've tried tRFC up to 85 without any luck and performance level 8.
