upgrade CPU E7600 to E8600


I'm still using my late 2009 27" iMac for simple tasks.

The EMC 2309 was offered by Apple with either a E7600 or E8600 CPU (both Core 2 Duo) 3.06 or 3.33 GHz

Today the E8600 CPU chip is very cheap (about $30) I've read that it's about 20% faster than the E7600

As it was offered by Apple, and knowing that the processor is socked on these models. Is it possible to replace my E7600 by E8600?

I have not found an answer on the web.

Thank you in advance

thank you very much for your answers.

I don't matter about the amount of work, it's mostly for fun

If I try myself to change the CPU, is there a risk to ruin definitely the computer ?

Thank you !

It's a lot of work as you'll need to remove the logic board out of the system. It is risky job and yes, you could kill your system if you mess up installing the chip.

It's still best to just upgrade the RAM & drives first. Trust me ;-} I speak with experience here.

Yes, you can upgrade the CPU to the E8600 Core 2 Duo CPU. But given the amount of work and risks I'm not sure it makes much sense here. I would point out the amount of memory and the HD offers more performance benefit than replacing the CPU if you haven't done anything yet with them.

I would push the system to 12 GB and look at upgrading the HD to a SSHD or if you want to go a step further, go with a dual drive config using a SSD. Here are the IFIXIT guides:

Here's the SSHD hybrid drive if you replace your current HD: Seagate Desktop SSHD. You will need this as well: OWC In-line Digital Thermal Sensor for iMac 2009-2010 Hard Drive Upgrade.

Sorry, if the CPU is user upgradable on this model, it would be just a matter of swapping it out, but I do not believe that it is.
