i7 26000 cpu

[The19thbear]

I seem to have a fixed max of 3.4ghz on my cpu in osx, even though its overclocked to 4ghz and is running fine in windows 10


I tried this:

sudo ~/ssdtPRGen.sh -c 0 because i have a sandy bridge.

I then get this:
System information: Mac OS X 10.12.6 (16G29)
Brandstring 'Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz'

Scope (_PR_) {220 bytes} with ACPI Processor declarations found in the DSDT (ACPI 1.0 compliant)

Error: board-id [Mac-27ADBB7B4CEE8E61] not supported by Sandy Bridge – check SMBIOS data / use the -c option

= Doesnt work. No increase in speed.

I then found out that i probably need to use a smbios that actually supports the 2600 cpu. So i tried the imac 12.1, but then my video card doesnt work. Black screen at login. (using a nvidia gtx 660)

Any way to take what is working (graphics) from the smbios 14,2 and take the rest that might be working from the 12,1?



What could i do?
Thanks

Try to run the script specifying different configurations.

SMBIOS flags without change your

./ssdtPRGen.sh -b Mac-7BA5B2794B2CDB12 -m Macmini5,3

If this command doesn't work, try to change -b and -m flag:

• -b Mac-942B5BF58194151B -m iMac12,1
• -b 
Mac-942B59F58194171B -m iMac12,2
• 
-b Mac-8ED6AF5B48C039E1 -m Macmini5,1

• -b Mac-4BC72D62AD45599E -m Macmini5,2
• 
-b Mac-7BA5B2794B2CDB12 -m Macmini5,3

If any of this works, you must change your SMBIOS to the same as you generated.

Specify the processor model

./ssdtPRGen.sh -s 'Sandy Bridge'

CPU Warning could be ignored.
If you get out the errors, you will can use the SSDT. Don't forget disable generate C-States and P-States from config.plist.

No cigar.

Just to get things straight:

i generate a ssdt.aml file from the parameters you gave me. Works fine.

I copy that to clover/ACPI/patched, and just reboot.
It should apply the new ssdt.aml file without me doing anything, right?
No need to do anything in clover configurator/config.plist, right?


I noticed this
by using: Macmini5,3:


Number logical CPU's: 8 (Core Frequency: 3400 MHz)


It seems to set the core freq to 3400 which is where my cpu is currently maxed. Is it possible to edit the core freq? Or is that taken from the bios?



Thanks

No. Put SSDT.aml file in /EFI/EFI/CLOVER/ACPI/patched and then open EFI/EFI/CLOVER/config.plist and search

<key>Generate</key>

Add below CStates and PStates to false, these prevents that Clover Overrides your SSDT.

<dict>
    <key>CStates</key>
    <false/>
    <key>PStates</key>
    <false/>
</dict>

Finally, use Multibeast or Clover Configurator to set your SMBIOS on MacMini 5,3 (same as you compile your SSDT). Reboot and open Intel Power Gadget to see the behavior of your PM (Power Management).

About the frequency, according with the Intel information about your processor 3.4 GHz is the correct value.

Thanks. Will try later

Ok. So no cigar. I can only boot with the 14,2 profile. So i guess that means no overclocking for me?

Why you only can boot with 14,2 SMBIOS? What are you using to change this values?

 

[The19thbear]

Because i get black screen when trying to log in, because of my gtx 660. I only get to the boot screen when using 14,2 smbios. All the other ones leave me with a black screen.

Did you see the black screen with nv_disable=1 flag?

 

[The19thbear]

Yes. Tried with the imac 12,1 and nv disable=1 and i can log in, but no graphics acc.
Cpu i still capped at 3,4ghz
I typed this in terminal to generate the ssdt:
sudo ~/ssdtPRGen.sh -b Mac-942B5BF58194151B -m iMac12,1 -c 0
