List of ALL Intel Core i3/i5/i7 Processors w/busratios

[tonymacx86]

So we know that these new i3/i5/i7s for the most part aren't supported yet by OS X. If you try to install, you'll get an instant reboot.

In order to avoid this, you'll boot using iBoot or whatever Chameleon Boot CD, swap out for the Mac OS X Retail DVD, and press F5, then you type:

busratio= and then your specific CPU's bus/core ratio.

So, for example, the command would be

busratio=23

For a Core i3-540. Simple! But as yet untested on a lot of these.

Below is a list of the bus/core ratio taken from Intel's site for all of their 2010 lineup. Enjoy this resource!

ellnic just installed Snow Leopard on his notebook with a 720QM and it didn't need a bus ratio setting.

Nice work - cheers!

Hy
you have a similar laptop than me exept the graphic card
what boot cd do you use for the install ???
thx a ton

 

[ellnic]

I actually used one of the original boot CD's by accident. The original P55 boot CD, here: http://tonymacx86.blogspot.com/2009/12/ ... -from.html

Good luck

If it's an instant reboot, then it's most likely not CPU related, but rather has something to do with your BIOS settings.

Instant reboot is due to the wrong busratio setting- just try different ones til it works! Enter

busratio=15

after swapping for the Mac OS X Install DVD. Then if that causes reboot, try busratio=16, and so on. You should put specs in your signature, or Old Gregg will be after your Bailey's.

What CPU do you have? If you have a newer i3/i5/i7, you'll need to enter the specific bus/core ratio as stated in the first post. Good luck!
