Q9650 Is a LGA775 Socket and there is several intel motherboards that support it
What is your SL number? You will find the SL number on the top silver plate of the CPU or on the sticker of the BOX.
You are correct in that there are several Intel motherboards that support it but you seem to have skipped right over the word "two" in my original post. I'm looking for a mother board that has "TWO" LGA775 zif sockets. Haven't found one.
