Can I fit xeon processor on a core 2 duo pc

Heavy Pootis · Jul 18, 2017

Hey Guys,

I have a core 2 duo pc so i want to upgrade it so can i replace the core 2 duo with a xeon processor?

Likely, but we can't help you without knowing your CPU socket type.

It depends on your motherboard. Some of the OEM boards may be limited to strict Core 2 Duo CPUs, while other boards may allow you to substitute one of the Core 2-based Xeons.

It all depends on the motherboard. Most likely it would have to support ECC RAM to be able to use the Xeon CPU. Without knowing the model of motherboard it's impossible to answer definitively.

Heavy Pootis :

What is the make/model of your motherboard?
Why? Two of the best CPU's for your socket may not be compatible with your motherboard.

One of the best for that socket type is a Core 2 Extreme QX9770 but it's not compatible with all motherboards, just like the Xeon CPU's. There's not much left available at retail these days but ebay has plenty of LGA 775 socket CPU's.

The best for that socket:

The best Xeon for that socket:

Most likely compatible and still awesome = QX9650:

Absolutely! Like others said, if your motherboard lists one as a compatible, even if it is LGA 775 some motherboards won't support it. My suggestion would be to look up the cpu compatibility chart/list for your exact motherboard and make sure your bios are the latest version.

What @dark_lord69 said.

It can vary quite a bit depending on the motherboard.

For example, I was able to find a few LGA 775 motherboards on PCPartPicker.com, all from Intel. Consider the differences between them, though:
-- The list of supported CPUs for the DQ45EK (https://www.intel.com/content/dam/support/us/en/documents/boardsandkits/desktop-boards/DQ45EK.pdf), a Mini-ITX motherboad, includes 3 dual-core Xeon CPUs (Xeon 3065, 3075, & 3085).
-- In contrast, the DG41CN is a more capable motherboard, as it can handle double the DDR2 RAM. However, it does not support Xeon CPUs (https://www.intel.com/content/dam/support/us/en/documents/boardsandkits/desktop-boards/DG41CN.pdf), even though it supports a faster Core 2 Quad (Q9650) than the DQ45EK board (Q9550S).
-- You also have the option of the DP35DPM mATX board, which is not only compatible with the same 3 dual-core Xeon CPUs as the DQ45EK & the Core 2 Quad of the DG41CN (https://www.intel.com/content/dam/support/us/en/documents/boardsandkits/desktop-boards/DP35DP.pdf), but is also compatible with 5 quad-core Xeon CPUs (X3210, X3220, X3230, X3350 & X3360).

So, 3 different Socket LGA 775 motherboards, all of which can handle dual- or quad-core Core 2 CPUs, but only 2 of them will accept Xeon CPUs, & of those 2 only 1 can handle quad-core Xeons. This is why it's critical to know which motherboard you have.
