Gabechrism Posted October 29, 2014 Share Posted October 29, 2014 I'm using an Acer Aspire V3-571G with a ICH7 series motherboard (panther point/ivy bridge) and a sandy bridge i7 2630QM 2.00GHz (you can probably see why I want turbo boost) and I'm running OS 10.10 Yosemite. I've tried the 10.9.0 patched kext. The result of installing that is booting seems to work up until the end where I get "p-state stepper error 18 at step 35 in context 2 on CPU 0" then a long pause and kernel panic due to the CPU power management kext so some but obviously not great progress. It's a problem that's been troubling me for quite a while and I would very much appreciate some assistance. Also is it possible to pop an ivy bridge CPU in there given the 7 series chip set and if so in what ways would I benefit if I would at all?

TimeWalker75a Posted October 29, 2014 Share Posted October 29, 2014 ICH7 motherboard is a 945 chipset board, get your data straight. What you have in your Acer is probably HM77 or HM75. Just use p and c state generators provided by boot loader and it will produce turbo states too. You can install a series 7 CPU, the sandy bridge you have there was put in the laptop to retail it for cheaper, no other reason. Link to comment Share on other sites More sharing options...
