That link doesn't work. How about being more polite as well. OP, it doesn't appear that motherboard supports core 2 quads, so cannot use that chip. Had your board supported a Q6600, an X3220 would work.
Thank you for your help logainofhades , i will have to find out whats the best cpu or most cores i can use in this board , and work from there, thank you guys .
My link may not work directly, but there is still a cpu support list in the Tech support tab. It lists this cpus as the fastest:
Intel Core™2 Duo 2.4G E6600 1066 4MB 65W Conroe P
Intel Core™2 Duo 2.66G E6700 1066 4MB 65W Conroe P
Intel Core™2 Extreme 2.93G X6800 1066 4MB 75W Conroe P
And as logainofhades says, it is an old platform and the system will not gain much performance with a fast CPU.
