SSDT generation script (Ivybridge PM)

[stuppy_]

I am in the same boat as the two guys above me. Been trying for days to get a working SSDT that gives me more than 4 states.

My system is as follows:

- Gigabyte Z77X-UD5H Rev 1.0 (using BIOS F16 mod11)
- Intel i7 3770k at default clock speed - 3.50GHz with Turbo up to 3.90Ghz
- Clover Bootloader booting in UEFI

I am using pikerAlpha's SSDT generation script and have tried several argument combinations and SMBios combinations.

If I use -w 3 argument when running the script, I can achieve P-States 16/37/38/39
If I use anything other than -w 3, all I get is is P-State 8 (800mhz).

I have tried all of the iMac SMBios's, MacPro3,1 (although this tends to idle at 3.70GHz rather than 1.60GHz). I tried Macmini but it fails to boot to the desktop, the screen just eventually switches off.

I am nearing the end of my efforts in trying to get it working. Any advice welcome.

Update:

So finally I got it work. It was not easy for the first time, but I understood the read me file and this is what I used for the script: "-p 'i5 3570K' -turbo 4200 -x 1"

Now I have checked drop OEM, xcpi -1, ncpi=0x3000 and drop tables typed in and unchecked generateP,C states.
Now I have 6 states AICPUPMI: CPU P-States [ 16 25 29 34 38 42 ] with imac13,2 and even with macmini6,2.

Am I done? Is this enough for proper PM?

Thanks

Something has clearly changed with Yosemite and power management. My SSDT was working fine with clover and Mavericks giving me ~10 states. Now I only get 16 37 38 39 with my 3770k. I've redone the SSDT and I'm sure it's on par, especially because it was working before. Has anyone documented what's different now? I can't really find all that many people even noticing this. Maybe the ivy's are too far gone for most to care now.

edit, to other's with the 3770k or similary ivy chips, try running the script with:

ssdtPRGen.sh -c 1 -d 3 -w 2 -x 1

then enable the new bootflag "-xcpm" (no quotes) in arguments

In bios set turbo "enable" and set turbo boost values by there actual numerical value not "Auto". disable C6/C7 and C1E

make sure all state generation in clover is off.

This seems to have gotten me better steps, at least more of them in the 20's.

Try to generate SSDT with

./ssdtPRGen.sh -w 3

I had similar issue. Here.

alright, thanks I'll play around with that, stupid question for you though, what are you monitoring that with in terminal? I've only known the kext method -kextloading / unloading msrdumper...

No stupid question, don't worry. Install the attached kext, reboot and run this command in terminal

cat /var/log/system.log | grep "AICPUPMI:"

I think this too, my i7-3970 don't slow down like in Mavericks (same settings) now 3.6 to 4.2Ghz but i don't remember mavericks values.
the script don't work any more (It seems that MacPro6,1 not supported by Sandy Bridge)

BUT : When in render 3D images, my cpu warms far less than before (Still got a 22313 GeekBench score)

Hello

Can anyone assist me in making an SSDT for my system (see sig/profile)

i7 2600 (non K)

sudo ./ssdtPRGen.sh

This incorrectly identifies my SMBIOS as imac 13,2 when it is infact 12,2

Also there is a warning:

'CPU type may be set improperly (0x0703 instead of 0x0603)

Error: board ID is not supported by SandyBridge - check SMB IOS date / use the -C option

Please advise

Thanks

I was trying to overclock my CPU Xeon E5 1650v2 and used SSDT generation script. Now HWmonitor shows me weird numbers like 4.6GHz and I have only 2p states 12 and 36 when it used to be 12 and 35. Please take a look and tell what can I do to fix it. I am afraid that is not working properly right now.

Edit: solved! all works now.

 

[N00Bster]

I'm writing from my hackintosh.

I just overclocked it so that the turbo goes up to 4.5ghz. after overclock I lost my generated c and p states and was not able to boot up correctly. After I booted my c and p states were 16 and 34. I tried to regenerate my c and p states but I got this message,

"Warning: 'cpu-type' may be set improperly (0x0703 instead of 0x0603)

Error: board-id [Mac-FC02E91DDD3FA6A4] not supported by Sandy Bridge – check SMBIOS data / use the -c option"

I do not understand what exactly this means.

So I then used chameleon wizard to fix up my smbios and changed it from 3,1 to 13,2 and added all the clock speeds and memory names and all of that including the random serial number. Hoping that would fix the problem but it did not and now I still get that same warning and error message. What am I doing wrong and how can I fix it?
