NM compatibility.

Just wondering if a 32 NM cpu can go on a 22 NM mobo? I know this might be a noob question sorry.

Thanks in advance.

If the CPU is pin compatible with the motherboard, it should work just fine and may only require a BIOS update. For example, Sandy Bridge & Ivy Bridge Intel CPUs are pin compatible. Not always 100% of the the case, but generally speaking it's true.

Wylie is right and gave a perfect example. As long as the chips are designed the same, electrically speaking, and the socket/pin layout is the same, then they should work. Newer CPUs may require a BIOS update from the manufacturer in order for the CPU to be recognized and for the new features to work.

It's always best to check with your specific MOBO but what they said. Update the BIOS first.

I found out that the 22nm requirement referred to OCing past a certain speed. I have a 3.40 i7 at 3.80 and it's doing great. But i was thinking about what is a safe max temperature the processor can be? I get 102f at the most right now. I have no reason to push it further at the moment but I was thinking about the future.

When you say at the most, is that with all cores maxed out? Try running Prime95 and see what your temps get to when your system is under full load. 102F is about 39C, so that is pretty cool.

Are you running a 2600K? If so, you can run that CPU up to 60-70C under without any concerns of CPU lifespan degradation. With a decent after market cooler, you could easily overclock to 4.4-4.6 GHz and keep it within those temps. It actually does make pretty noticeable difference in gaming performance.

I meant that was the highest temp I am getting while running bf3 on high etc. It is a 2600k 32nm i7. I have two spots on the top of my case for fans, I thought about installing one blowing in and one blowing out.....
