is it possible to mount a xeon 3440 processor on an Acer Aspire x3900

I ask this question because I have this processor in my hands … I installed it and it doesn’t work … I updated the microcode with mmtool but it still doesn’t work … through the amibcp tool I saw that in the “Active Processor Cores” i can set a maximum of 2 cores … is it possible that this is why i can’t get it to work ?? is there a solution ?? sorry for the english: P
