Here is the deal. I have to go work soon, so I might not be able to give you all the information needed. I am thinking about upgrading my computer CPU Processor to a AMD Athlon 64 X2 6400+. I dont know if it will be compatible, so I was wondering if someone can help. I have a: Compaq Presario SR5507F Asus M2N68-LA (IVY8) *Motherboard At the Compaq website, it states that I can run all AMD Athlon 64 X2 Processors. Is this true?
