Hey all, Ive got a computer running a core 2 duo with a FSB of 1066mhz. A buddy of mine gave me a Core 2 duo CPU but it has a FSB of 1333mhz.
Will the one my buddy gave me work in my computer? They are the same socket right?
Thanks in advance!

I don't believe it will work. LGA 775 had several generations. The first generation was the Pentium 4 5xx and 6xx and Pentium D chips. The second generation was the first generaton 65 nm Core2 chips like you have now. The last generation were the 45nm Core2 chips like the E8400 your friend gave you. While the older chips were supported on the newest motherboards the newer chips would not work on the older boards. This is especially true with the OEMs like Dell as they have no reason to make their systems upgradeable because they want you to buy a new Dell.


I just pasted 0RF703 into google and saw a few threads where the e8400 wouldnt post on that Motherboard.

The chipset that is being used on this board is the Intel Q965 which doesnt support the Intel® Core™ 2 Duo processors without a Bios upgrade from the motherboard manufacturer and I have not seen it support the Intel Core 2 Duo processors with a 1333MHz FSB at all. The 965 board that I used to own topped out at the Intel Core 2 Duo Q6700.
 


I see, well it looks like you where able to put a quad core in. Ill try that! :sol:
 
You have to realize that even if the chipset officially supports certain processors that does not mean Dell wrote BIOS support of those processors into that board. It may not support Quads at all. There is very little information available about what exact chips your board will support. Contact Dell and ask them to be sure before trying any upgrades.

You should also understand you would be putting money into what now is essentially obsolete, dead tech. I certainly don't recommend spending money on trying to do limited upgrades to what you have. You are much better off with either building or buying a completely new system even if that means having to wait while saving money.

For $200-$250 you can get a brand new CPU, motherboard and RAM that will run circles around what you have now.
