Hello Im new to the forums, well im always searching on here :) , and i just have a question for all the pro's. I have a HP DC7700 CMT and the motherboard is a HP Model 0A58h. Im looking to upgrade the CPU from a Intel Pentium D 945 LGA 775 Socket to a Intel Core 2 Extreme QX 9650 also a LGA 775 Socket and i'm wondering if this will work. I know i might need a BIOS update but any feedback would be greatly appreciated. :)

Thanks for your help. I guess im goin to swap motherboards but now i need to know what size the board fits or does that matter. Sry if this sounds dumb but im a newb when it comes to this :)

I couldn't find anything about what type of motherboard you can use. There are different standards the most common being ATX and micro ATX. Sometimes though big name companies use a proprietary board meaning it doesn't follow the ATX standards. If you want to use your old computer case you would have to buy another proprietary board from the manufacture (HP in your case). I don't know if that is the case with your computer. I guess the only way to find out is to call HP. Also getting a new board also means you are probably going to have to get new RAM because there is no definite promise that your old RAM will work with your new motherboard.
