Please check the first post of this thread - it‘s a wiki post and your questions have been addressed there...Thanks for your help! Will any Ivy Bridge CPU work well? Or are they all messed up somehow?
Also, are Sandy Bridge or Ivy Bridge Xeon CPUs better than i7 2600? And do they work well? Or also messed up somehow?
Latest on the 2011 iMac family is 22.214.171.124.0 and because your firmware contains some hardware identification which is used to handle iCloud security it is a bad idea to share it on a public thread like this.i got dump 126.96.36.199 firmware from iMac 27 inch but i cant say what exactly chip was here, so i did backup using the romTool with each provided by the program select items
yea, i removed it, but as i found some info that there is a chance that downgrading firmware could solve the issue with xeon v2 and 37 series cpus.Latest on the 2011 iMac family is 188.8.131.52.0 and because your firmware contains some hardware identification which is used to handle iCloud security it is a bad idea to share it on a public thread like this.
If I will find an older 2011 iMac containing an older MacOS than 10.8.3 version I will get the firmware off it using a Ch341A clip. Probably somebody can work out then if there is another firmware part allowing the installation of Ivy Bridge.
Does anybody know of an online firmware database for such 2011 iMacs?
Why you want to go this route? It breaks sleep and you get no real more power than with the i7-2600.
Hey pal I just bought a 2600 i7 for my mid 2011 iMac based on your feedback and image comes up during boot and then goes black once finishes loading, seems like the CPU is taking down the GPU, the computer finishes loading but no image. I have an AMD WX4150 video card Wich I checked that has same TGP value than your K1100m (45W) and I also have one SSD installed, disconnected the DVD an I still get low power, what you'd you think I'm missing? I put back the i5 and everything goes fine so it's definitely the i7 sucking up the power 😅 any help will be appreciated thanks!I have an i7-2600 in a 21" 2011 and it works ok but it's right on the edge. The power supply doesn't have enough oomph left to spin up a regular 3.5 hd. With no 3.5 hd, dvd replaced by an ssd, and a K1100m video card it all works ok. (These changes all use less power than the original config.)
If I were going to do it again I'd go with the Xeon E 1220 ($20 on ebay) or 1230 which is almost as fast but only pulls 80 watts vs 93 for the i7-2600.
