Throttlestop Optimization

[kylanty]

Hello, I've been using ThrottleStop for a while now, utilizing it solely for the cpu and core under-volting part, and I was wondering if there was any further optimizations.

Here are my settings & specs:
(undervolt is @ -115 and 105 for cpu and core, all I've done)

ThrottleStop shows your computer is overheating and thermal throttling. There is no way to get maximum performance out of your computer until you find a way to reduce the CPU temperature. Have you ever opened up your computer and cleaned it out? Have you replaced the thermal paste?

The 8550U has a 15W TDP rating. When the power limits are left unlocked, they can easily consume 30W to 40W. To sustain maximum performance, the cooling system has to be in peak condition. Many laptops with these processors use barely adequate heatsinks. They were not designed to fully cool the heat that an 8550U can put out when the turbo power limits are left unlocked.

Hey @unclewebb,

I do intend to open my laptop, wipe the dust and add new thermal paste in the future. However, I did replace my dell battery (for some amazon online battery) and use powercord only. I also do have questions foremost;

I have throttlestop enabled after every signup; does this lead to intel ppm inhibiting performance? I have it disabled while using throttlestop all the time, but while utilizing throttlestop, my laptop sometimes bsod, crashes, or freezes upon hard load.

Should I also mess with anything on the front panel of throttlestop;

anything to enable option tabs;

what is pp0 turbo limit for tpl;

and what should I just leave alone and focus on optimizations?

Thank you unclewebb!

while utilizing throttlestop, my laptop sometimes bsod, crashes, or freezes upon hard load.

I have an 8550U that will start to lose stability if the cache voltage is set any more than -70 mV. A computer should never crash. If you see a BSOD, your undervolt is too aggressive. Your CPU needs more voltage.

I prefer to enable Speed Shift Technology in the TPL window.

There is no need to check the PP0 Power Limit. Leave it as is.

Check the MMIO Lock box if you ever get around to improving your cooling. No point in spending too much time adjusting anything until you fix the cooling and voltage problem.

The problem is whenever I set my voltage too low as in -100 and below, my cooling problem appears and for some reason now, my laptop runs at full throttle when it doesnt have to be.

Can you critique my throttlestop and give me tips for optimizations, unclewebb?

my laptop runs at full throttle

Run a log file that shows this throttling.

I would not check the BD PROCHOT box on the main screen. I would set Power Limit 4 to a value of 0. Set IccMax to the max for both the core and the cache.

my cooling problem

Yes, that is the problem. Playing around with ThrottleStop is not going to fix a cooling problem. If you want to run your CPU beyond its 15W TDP rating, you need much better cooling. If you do not have time to fix the problem, try reducing the turbo power limits so your CPU does not reach 100C.

With these settings, I continue to bsod, crash, etc, despite being fine running @ ~-120mv 2 weeks ago with different settings. The settings that were ‘running fine’ are a reiteration of what is occurring now for me.

anything to fix or optimize this?

I also kept crashing and couldn’t create a log file**
