Proc upgrade for hp zv6000

I am looking to upgrade the proc for my zv6000 and I was hoping that someone could verify something for me.
Per HP, the highest sempron I can go with is 3100. can anyone verify if this is correct or not? I would like to go with a 3300 if I can but I cant find anyone that can say for sure if it will work or not. (while HP did say that it wouldnt work, they also said that the highest I could go was actually 3200 which AMD shows as being a desktop proc not mobile so I dont have much faith in their answer).

<edit>
whoops... sorry... 3200 is not a desktop proc specificly.. its an athlon proc, not a sempron
