Hello there fellas i have an old lenovo all in one computer it is a lenovo thinkcentre m71z it have a i3-2120 cpu 3.30ghz i manage to get a Quad Core i7-3770 Processor 3.40GHz Socket LGA1155 how do i know if it will work on that machine and if so do i have to do anything special before or just swap the cpu?

From there, the chipset (Intel H61)

Then this:
But changing a processor on an AIO is less than ideal. But here is the CPU:
and the breakdown here:
Buy thermo paste
If your not willing to throw it away, I wouldn’t do it.

Looking at some pictures, I see that the M71Z motherboard has a regular CPU socket. So in theory the CPU should slide straight in.
If the default cooler doesn’t use a thermal pad, you’ll need to apply new thermal paste.
That being said, on those old Sandy Bridge (2xxx series CPUs) motherboards you often needed to do a BIOS update to properly support Ivy Bridge (3xxx series) processors. I don’t know if Lenovo ever pushed that out for this machine because they just didn’t sell that many of them. It may or may not work, but there’s only one way to find out and that is to update the BIOS, swap the CPU and pray that it runs properly.
Theres also the concern about power draw. The 3770 will use a lot more power under load than the old 2120. Those all-in-one machines usually have a power delivery setup that’s only just powerful enough for the original hardware. If you’re going to put in a CPU that uses a lot more power, you could run into problems there.
I’m not too worried about thermals. The 2120 has a 65W TDP, the 3770 has a 77W TDP. Still, if the original CPU can run hot with the original cooler, those extra 12W of heat could push the temps to the point of thermal throttling, in which case you’re not going to get all the performance that the 3770 has to offer.
Personally, I wouldn’t do it. Even if it works properly, I highly doubt that the bit of extra life is worth the cost of the 3770 and the time you put into it.

Thank you very very much believe next step is build a new machine with this cpu!
