BD_PROCHOT option doesn't work

[sooxt98]

although memory leak doesn't happen anymore, but the cpu somehow still capped at 1.5 Ghz, BD_PROCHOT option does not effect on my bad battery @christophe-duc plz help me

I did notice that Bi-Directional Processor Hot is disabled by CPUTUNE in the config but does no effect on the throttle

cc @schdt899 to take a look

[sooxt98]

If im not wrong, tweaking BD_PROCHOT wont help for broken battery, the issue persist since https://github.com/syscl/CPUTune/issues/8

As my MBP Current Performance State Value is capped at 1500 MHz without any reason

MSR_IA32_PERF_STATUS.............(0x198) : 0x167200000F00
------------------------------------------
 - Current Performance State Value...... : 0xF00 (1500 MHz)

The only way to make it work is to find out what capped that value, or maybe direct tweaking that value could make it work

[sooxt98]

I finally figure it out, i read thru this post again and again https://portugnole.blogspot.com/2020/05/running-macbook-without-battery-lets-go.html

The main problem here is IOPlatformPluginFamily.kext, which is the main reason that throttle the speed; So it needs to be removed.

The last step is enable HWP 0x770 & disable BD_PROCHOT 0x1FC & disable turbo boost 0x1A0

./voltageshift write 0x770 0x1
./voltageshift write 0x1FC 0x24005E
./voltageshift write 0x1A0 0x4000850089

But the problem here is after removing IOPlatformPluginFamily.kext, the latest CPUTune will cause KP when load kext which i didn't notice at first that's the reason why CPUTune not working. cc @syscl

So currently i'm using voltageshift to modify MSR value directly

But now Im facing another issue where macbook auto shutoff after 15min of using ....

Update:

I found out that I can direct changing the capped value (Target performance State Value) to 2.3MHZ 0x1700 which allowing us to ignore the last step (enable HWP 0x770 & disable BD_PROCHOT 0x1FC & disable turbo boost 0x1A0)

./voltageshift write 0x199 0x1700

Yeah after 15min, shutoff not happen anymore :3 new method works!

[sooxt98]

I tried to benchmark with turbo boost on, my mac literally goes off after reaching 87++ celcius ... Not sure why

[sooxt98]

Another weird situation, I let my Mac sleep for few times, then I use for about 30min and it become more slow and laggy and finally suddently freeze at there. The cpu are all in normal stat, the power consumption becomes not stable anymore, spiking every 3 seconds up and down; my guess is it could probably cause by removing that Intel kext 🤔

[sooxt98]

updates: This method still works on BIG SUR :3

Spiking solved with BD_PROCHOT disable; If i'm not wrong enable HWP will makes macos crash.

So these two command are the perfect command

./voltageshift write 0x199 0x1700 
# Tweak Target performance State Value to 2.3MHZ 
# (It varies depends on what cpu model are you using, change the `0x1700` according to your CPU model max performance MHz (when turbo off))
./voltageshift write 0x1FC 0x24005E 
# Disable BD_PROCHOT (warning: only for me, please read the guide below)

Guide for disable BD_PROCHOT

1. you need to get default hex with

./voltageshift read 0x1FC

2. in this case, my hex is 0x24005f , simply replace the last character with 'e', so it would be 0x24005E
3. apply the changes

./voltageshift write 0x1FC 0x24005E

[syscl]

Thanks @sooxt98 for detail procedures, sorry for the late reply due to on call last week. So the correct step is to change the target value first then disable BD_PROCHOT right?

[sooxt98]

@syscl yes, and also need to remove the IOPlatformPluginFamily.kext to make bd prochot works

[davibennun]

@sooxt98 I think im on the same boat, My CPU is capped at 0.8ghz, it looks like the Bi-Directional Processor Hot is disabled by CPUTUNE but the throttle still persists. I also removed IOPlatformPluginFamily.kext.

I tried to manually disable BD_PROCHOT using voltageshift as per your instructions but ./voltageshift read 0x1FC gives me only:

(00000000 00000000 00000000 00000000 00000000 00000100 00000000 01011110)

Can you please shed a light on this issue?

@davibennun if im not wrong, the binary is 4005E which shows that u have already disabled the BD_PROCHOT

[sooxt98]

@davibennun what u need to do now is this, i saw your config, try command below

./voltageshift write 0x199 0x1B00 # Tweak Target performance State Value to 2.3MHZ

so you're now actually tweaking 0x199 to get back normal performance, its like a max speed capped of ur current cpu state (Target performance State Value)

[davibennun]

@sooxt98 I got my CPU back to max performance after running the command you suggested. THANK YOU SO MUCH! I'm battling with this for over a day, I'm so happy to see my CPU working fine again.

@sooxt98

MacBook usable again.

Amazing, thank you.

[sooxt98]

btw i did found out that, performing full factory reset on macbook and upgrade to bigsur will solve the throttle problem;

@sooxt98 I'm on Big Sur already, with a bad battery. The slightest workload brought the CPU down to 800mhz. Nothing worked, until I tried your solution. The MacBook now runs faster, quieter, cooler.

Well, this worked for me, but now after several hours of use, somehow the 0x199 keeps going back to 800Mhz every few seconds. I have

1. IOPlatformPluginFamily.kext removed
2. NoBatteryNoProblem.kext loaded
3. BD_PROCHOT disabled via ./voltageshift write 0x1FC 0x24005E
4. Now I am running a while loop to set ./voltageshift write 0x199 0x2200 every second to even make this comment.

This started after I inserted an external hard drive and since then I am not able to keep 0x199 to higher speeds :( @syscl @sooxt98 Any idea how I can figure out what's resetting 0x199 back to 800Mhz ?

Update: 0x199 is now persisted after I rebooted and it works again. So seems I cannot attach an external drive or else it reverts and then I need to reboot (which of-course takes ages due to no battery) to be able to enable again. That's a bummer :(

i'm also having 0x199 revert to ~0.9mhz every few minutes; no external hdd, only peripherals are keyboard+mouse+monitor. im on monterey 12.5.1, so most of this still works up to that version at least; i'm happy to help anyone resolve any issue if they have one!

does anyone have a solution for the reverting 0x199?
