oops sorry wrong button
same thing on my machine with the t8100
its OK though I'm going from a single core m550 to a duo core 7300 with same speed basically and real good cache
it seems dell has more than one mobo for my machine and wont talk to me without bookoo bucks
OK back to hp for my personal machines
but cant live in a box live and learn
hp has great tech service and don't mind giving away info
i have one i bought in 2005 and can still talk to a tech for free good for me
anyway ill post my results on the t7300
maybe it will help someone else out for free
thanks again guys
