Help with AMD bootcamp

[Giova]

Hi everyone, i have a AMD 5500M in my windows bootcamp (macbook pro 16" 2019), i'm finding various problems.
when i start gaming, right after starting the computer, i open a game and the work load on GPU is kinda good: 80% or something and like 50 degrees (CPU it's apparently not a problem), anyway after few minutes of gaming (the time depends by the weight of the game) the temperature get stuck at 70 and work load at 100, even if i didn't change the game so i thought that was thermal problem or whatever. Can someone help me to setup the right throttle stop preferences?

atm in MSI Kombustor in MSI-01 i get an avarage fps of 7 and gpu load 100 with 70 degrees
here the screenshot of my actual settings

P.S nothing changes if the program is running (with theese preferences)

Your CPU power limit is too high and the SMC is intentionally throttling available power to avoid a meltdown. I've owned a 15" 2012 unibody Pro (the last of the classic non-Retina models) with a i7-3615QM and GT 650M/512MB, and at stock, just the CPU and GPU power exceeded the maximum output of the 85W MagSafe. The behavior that it displayed was exactly the same. The honest, raw truth that I have to give to you straight is that your Mac was never designed to be able to take full advantage of its processing power. It doesn't have the thermal dissipation capabilities or a power supply with enough capacity to do so.

This becomes especially apparent when you are running Windows, which doesn't have the macOS's aggressive power management features (which, by the way, do not solve the fundamental problem with the MacBook line, you cannot take advantage of your hardware's full capabilities because of the power and thermal constraints - this is a machine built with form over function). There's nothing you can do but lower your performance 2 or 3 notches below what it should so you can keep the entire CPU+GPU power load at around 70% of your MagSafe's wattage - the screen, wireless communications, backlit keyboard, etc. will take the rest of the power available. If your MagSafe is a 65 watt unit, you've got 40 to make do. If it's a 85 watt unit, you've got 60 to make do. No more than that, or your computer will repeatedly run into these power source problems - it cannot be "fixed", this is by design and by purchasing a Mac you agreed to this.

If you continue to get throttling problems even after you lowered the CPU + GPU maximum draw below this threshold, your next resource is to either turn the laptop's panel off and use an external display (thus saving some 5 W of power or so), or further reduce the system's performance and power footprint so it operates below the MagSafe's maximum capacity at the expense of performance.

It looks like your Macbook has poor cooling. PROCHOT 100°C glowing red indicates that your computer has been thermal throttling. Maybe that is the problem.

Check the Log File box on the main screen of ThrottleStop and try to play a game for 15 minutes. When finished testing, exit ThrottleStop so it can finalize the log file. On a Windows computer it should be in the ThrottleStop / Logs directory. Hopefully boot camp works the same. Attach a log file so I can see what your CPU is doing and what temperatures it is reaching.

Also post a screenshot of the FIVR window.

sorry for late, here it is what u asked. Regarding the logs, idk why, buy it doesn't create the file, checked the box and checked the logs folder, but he just refuses to create the file

If I were you, I'd cut the CPU's speed to ~3GHz in TS as the MBPro's cooling system is limited to about 52W of power dissipated in a 21C room. It'll run at or below 3.0 GHz at 100C at these cooling limits in an all-core CPU load. Gaming doesn't use these high loads but the processor prefers to shoot up to 4+ GHz which uses proportionally more wattage for one or 2 high-clocked cores instead of spreading the load to additional lower clocked and lower-power CPU cores. Wattage which instead should be used for the 5500M as both share the cooling system's single heatpipe. The 5500M should always be your limiting factor when gaming so anything you can do to transfer the available cooling/wattage to it will help.

If you have the control in Throttlestop, I'd just start with 3GHz flat for the CPU and game/test with it to see if performance is maintained or improved and temperatures improve. At 3GHz you should still not be CPU bottlenecked in most or maybe any games.

That doesn't matter, trust me on my advice: the Mac has a custom embedded controller which controls the power and thermal characteristics called the SMC - and it will issue prochot signals to throttle your CPU even if it's not actually at the thermal point. This is intended to keep the power supply from overloading. Less is more. Do as @Lew Zealand says and lower your CPU speeds, 3 GHz is a good starting point but you may need less to keep the power within your thermal budget and also what your MagSafe adapter can handle.

Macs are not gaming PCs. You will never have a great experience with one. The new Apple Silicon Macs greatly outperform the Intel ones when limited for power, so consider selling your Mac and buying an M2-based MacBook if this is important to you and you don't want to leave the Apple ecosystem.

ok, i got important updates.
1) pls Lew zealand tell me how to do the things u asked me to try
2) DR.dro i know what u r telling me, but i still wanna try the most i can do to still using this PC
3) unclewebb i now have the log files of a gaming session (from 22:50)
4) i had a kind agood upgrade of performances after following this video abt AMD Drivers

In the Turbo FIVR control window, in the Turbo Ratio Limits section, click each of the numbered core entries and reduce them to 30. Click the OK.

However I wonder if it's gonna let you as they look grayed out and thus inaccessible. I believe a firmware/BIOS update to my aged 2014 MacBook Pro eliminated this choice when I use it in Bootcamp, but this isn't uncommon in recent corporate-originated machines since they all patch for Plundervolt which seems to lock this choice out as well. Pain in the butt but maybe unclewebb knows more about whether this is unlockable in another way.

SMC doesn't issue prochot for power state shifts, that's asinine and inefficient. It has a dynamic VF table to handle that. The SMC forces prochot triggers to keep the chassis temperature from exceeding FCC legal limits, and if the cooling is compromised it'll happen when the CPU actually does reach 100C. The 16" Intel MacBook doesn't use MagSafe, for the record. It uses a 96W Type C power supply, and it has no problems powering the 75W ASIC power that Apple defined for the CPU+GPU.

MacsFanControl and ThrottleStop are your friends.

 

[Giova]

Ty Lew anyway, but as u geussed, i can't even interact with taht GUI

 

[Lew Zealand]

MacsFanControl and ThrottleStop are your friends.

Yes! MacsFanControl is a must, it gets installed on any Intel Mac I need to use, whether it's on Mac OS or Windows. FYI I set it to monitor CPU PECI with a 50-85C ramp and change it to GPU PECI or similar when gaming.

 

[Giova]

yeah, i'm already using it

Yeah, some of my info on Macs are somewhat to very out of date

I had no idea this was already one of the USB-C models, but if that's the case, I stand corrected
