Dell Precision 5530 i7 8750H unable to undervolt using throttlestop?

[cumdogmillionaire]

Has anyone got any knowledge utilizing throttle stop for this particular Dell model and CPU. The laptop seems to be heating the hell up so was hoping to try undervolting it and have some measure of improvement as I have had with my other laptop with the infamous i7 9750h.

Any help is appreciated, thanks!

Post a FIVR screenshot.

Not at all sure why its not wanting to work. After reading online though it seems certain version of the bios for these laptops were locked down.

And these are the logs.

In BIOS, select Factory Defaults (or something like that) to return to factory defaults and this way, possibly, undervolt will be allowed again.

Then you need to disable Core Isolation and Virtual Machine features in BIOS.

@cumdogmillionaire
The problem is VBS is enabled. Disable core isolation memory integrity and follow the info in the links in my signature if you need help. Exit ThrottleStop, delete the ThrottleStop.INI configuration file, reboot and try again. Post an update FIVR screenshot. You should not be seeing a column of odd ball 0.3799 voltage values in the voltage column of the FIVR window. That is a big red flag that VBS is enabled.

@PHVM_BR success! Tried what you said and it worked a treat. Currently sitting stable at -180mv Core and -150mv cache. My dell precision has the worst cooling design known to mankind. I'll be applying Honeywell PTM7950 down the line and updating the results. Currently it stands at 6478 cinebench R23 results, over the stock 4774. This has been a huge improvement. From my testing its also decently reliable.
@unclewebb The only remaining question I had was how can I ensure Throttlestop autostarts with windows?

-180 and -125 mV is pretty heavy undervolt, I was thinking the same that my 8750H is stable at -130 but I got some very rare blue screens when the notebook was idle, so I went for -100 (core and cache) and everything is stable for months. Cinebench is not a normal use scenario, test it by your normal habits. Gaming, browsing, editing, programming, watching movies, installing programs etc, the crashes can happen in mixed usages scenarios, not always at full load. And after few weeks or months you can save the Throttlestop .ini config file for future usage.

I wasn't aware of that. I'll keep a closer eye on it. It's never been used for gaming, just working, browsing and streaming. I'll keep an eye on it and update this thread down the lines. Thank you for the help guys!

how can I ensure ThrottleStop autostarts with windows?

You can use the Task Scheduler to autostart ThrottleStop when Windows starts. Here is a guide.

Effective clock speed

Hi, I have a problem with my CPU (8700K), which is that my effective core clock speeds decrease after a while. I have an all core OC set to 4.7GHz and initially when starting the PC, the effective core clocks are 4.7GHz as well when CPU is under load. These are later (like 10 mins later after...

success!

Good work! I always like seeing another ThrottleStop success story.

I would not use Cinebench for stability testing. It almost always takes more voltage to be "game stable" compared to being "Cinebench stable".

replace thermal paste (or go hype way and put a TIM pad like HoneyWell BS or other stuff like that). (generally, Arctic MX-6 or Noctua NT-H2 paste will do same "magic").
clean the dust. put laptop to a stand, even without fans, just raise it from the desk so it could get fresh air from bottom.

Windows scheduler worked a treat from what I can tell, Ta! I'll keep an eye on it as well for stability issues. Hopefully though I wont need to revive this thread haha.

@AleXXX666 You dont think that the HoneyWell Pads are worth the money? The laptop wont be sat in one place so a riser or a stand is kind of redundant. Its my main device when travelling light, its worked great for my needs in terms of performance and battery life. Its just the heat output and cooling was previously an issue.

yeah I understand that this laptop is quiet a machine even today
I just don't understand all this "hype" around "exotics" thermal conductivity materials such as LM or "recently" released "pads".
Back days we were all happy with paste, now just pastes compound has changed, and I do know that using high quality paste works well with proper cooling (which I know for sure for this laptop isn't an issue compared to my crappy ASUS TUF with sh*tty cooling... lol)

I mean I have indeed repasted it. Stuff like deep clean, re-paste, fresh windows install and bloatware removal happen well before I begin using the laptop. Now I can atleast get confidently say I've undervolted it so that stability is near enough perfect.

As for the hype around the thermal pads. I don't think I'm knowledgeable enough to comment as to whether there is any truth to the varied results we see in reviews or if its just margin of error measurements at times. However for the measly price of $40 for a pad thats large enough for both my laptops, I personally think its worth the investment when you take into account how much I use both of these and how reliant I am on these. Especially my precision, this thing has been my workhorse for the past 4yrs. Constant usage and has been everywhere I've been. If I can divide that cost of $40 by the hours I use this in a month its definitely worth the couple of pints a week that I would need to cut back on to justify it. Just my 2 cents though. I will be sure to update this thread once I get around to applying the PTM7950 pads. I've got about 6 or 7 runs pre PTM7950 so will try replicate that down the line.

well, if it has already worked for 4 years, it's like a half of "normal" age for such a laptop, "modern" enough hw taken to account. Any consumer-grade notebook will RIP normally after ~6 years. Based on experience with "consumer" and "business" grade of many laptops. So, if it works ok, let it work, use stand where available, also, if you don't need full performance 24/7 you can disable HT or turbo too, no need to do some "deep" things like UV.
