anibalin Posted January 17, 2012 Share Posted January 17, 2012 hey guys, im struggling with this one. core i5 650, bios build #28 / Using chimera 1.7 & 10.7.2 The problem is that I get AICPM kp at boot. This is the Scope PR for i5 processors: Scope (_PR) { Processor (CPU0, 0x01, 0x00000410, 0x06) { } Processor (CPU1, 0x02, 0x00000410, 0x06) { } Processor (CPU2, 0x03, 0x00000410, 0x06) { } Processor (CPU3, 0x04, 0x00000410, 0x06) { } Processor (CPU4, 0x05, 0x00000410, 0x06) { } Processor (CPU5, 0x06, 0x00000410, 0x06) { } Processor (CPU6, 0x07, 0x00000410, 0x06) { } Processor (CPU7, 0x08, 0x00000410, 0x06) { } } Â If I use the dsdt file without scope pr on it I get at boot time: ACPI CPUs not found: C-States not generated !!! ACPI CPUs not found: P-States not generated !!! But system loads up ok. However, If I add scope pr to dsdt file I get: SSDT with CPU C-States generated successfully SSDT with CPU P-States generated successfully but I get this KP afterwards: "Should have 4 threads, but only found 5 for Die 0". http://dl.dropbox.com/u/363153/IMG_20120117_191817.jpg I really dont get it. Thanks in advance guys. smbios: http://pastie.org/private/dtkqpoanyy3iiagze2cg org.chameleon.Boot.plist http://pastie.org/private/fnegwxkoilukge1jalg2lg dsdt.dsl file: http://dl.dropbox.com/u/767459/DH55HC_dsdt.dsl Quote Link to comment Share on other sites More sharing options...
Cassio Posted January 18, 2012 Share Posted January 18, 2012 Have you tried with older BIOS versions? I read about other Intel boards which only work (AICPUPM) using older BIOS (0144 for DP55WB) http://www.insanelymac.com/forum/index.php?showtopic=228310 Quote -Donations- PayPal HERE - Stripe HERE - BuyMeaCoffee HERE - Mercado Livre HERE Skrill danielnmaldonado@gmail.com - BTC 33HeGCuCSh4tUBqdYkQqKpSDa1E7WeAJQ3 PicPay @danielnmaldonado - PiX @danielnmaldonado@gmail.com Premium Users HERE - Problems with Paypal HERE Link to comment Share on other sites More sharing options...
anibalin Posted January 18, 2012 Author Share Posted January 18, 2012 for the sake of helping others: I felt a little creative today and changed the scope from: Scope (_PR) { Processor (CPU0, 0x01, 0x00000410, 0x06) { } Processor (CPU1, 0x02, 0x00000410, 0x06) { } Processor (CPU2, 0x03, 0x00000410, 0x06) blah blah to: { Scope (_PR) { Processor (CPU1, 0x01, 0x00000410, 0x06) { } Processor (CPU2, 0x02, 0x00000410, 0x06) { } Processor (CPU3, 0x03, 0x00000410, 0x06) blah blah The hint? was the die 0 at the kp. Made me wonder if it could be just that...and it was. Quote Link to comment Share on other sites More sharing options...
anibalin Posted January 18, 2012 Author Share Posted January 18, 2012 thanks for your reply Cassio. Yes, that was the first thing I tried. I had a dp55wb and was aware of the bios build too. Thanks for the kind pointer though. Warm regards. Quote Link to comment Share on other sites More sharing options...

anibalin Posted January 20, 2012 Author Share Posted January 20, 2012 Cassio any hint why I may be getting LPC device initialization failed C-state power? AppleLPC gets loaded though. Quote Link to comment Share on other sites More sharing options...
Cassio Posted January 20, 2012 Share Posted January 20, 2012 Maybe bad _CST in SSDT? Check the generated tables. Some people use custom SSDT instead of Chameleon "generate P & C states" http://www.insanelymac.com/forum/index.php?showtopic=259066 Quote -Donations- PayPal HERE - Stripe HERE - BuyMeaCoffee HERE - Mercado Livre HERE Skrill danielnmaldonado@gmail.com - BTC 33HeGCuCSh4tUBqdYkQqKpSDa1E7WeAJQ3 PicPay @danielnmaldonado - PiX @danielnmaldonado@gmail.com Premium Users HERE - Problems with Paypal HERE Link to comment Share on other sites More sharing options...
Chancer Posted January 20, 2012 Share Posted January 20, 2012 That happens with me when I enable Use Kernel Cache. Try disabling it.

on29thjun Posted September 15, 2012 Share Posted September 15, 2012 Hi, I got DH55TC (Bios #48) which is similar to DH55HC - Core i3 530 SMBios- iMac 11,1 running mountain lion 10.8.0, I am able to generate PStates using the following processor scope, Scope (_PR) { Processor (CPU1, 0x01, 0x00000410, 0x06) { } Processor (CPU2, 0x02, 0x00000410, 0x06) { } Processor (CPU3, 0x03, 0x00000410, 0x06) { } Processor (CPU4, 0x04, 0x00000410, 0x06) { } Processor (CPU5, 0x05, 0x00000410, 0x06) { } Processor (CPU6, 0x06, 0x00000410, 0x06) { } Processor (CPU7, 0x07, 0x00000410, 0x06) { } Processor (CPU8, 0x08, 0x00000410, 0x06) { } } I get PStates Generated but end with a Kernel Panic as shown in the picture. I cannot downgrade to BIOS #28 as my processor is not supported in that version. Have you achieved native speed stepping ? Please share your DSDT.
