Acer Aspire A715-72G Undervolting - Total noob needs help

[f1223]

Hi!
I'm having problem with Core Thermal Throttling in my laptop. I don't have much knowledge on CPUs and stuff, but I've done some research and it turns out that I should undervolt my CPU.

Laptop model: A715-72G
CPU: Intel i5-8300H @ 2.30GHz, 2304 Mhz, 4 cores, 8 logical processors

What options should I choose?
What and how to set up?
What values?

Please help, I'm totally green

Can you attach a screenshot for the TPL window?

At least memory speed data is correct!

Not really, because these are DDR4 2666 MT/s modules.

Nope, it's DDR4-2400 for that model (8 Gb). All fair.

And does it support?

Core Thermal Throttling

When was the last time you cleaned out your laptop? If the answer is never then I would do that first. The 8300H has a 45W TDP rating. Your CPU is overheating when the CPU is only running at 35W. That is a cooling problem. Undervolting can help but it can only do so much if a laptop is filthy inside.

To undervolt, open the FIVR window, check the Unlock Adjustable Voltage box and set a negative offset of -100 mV for the core. Set IccMax for the core to the max, 255.75. Do exactly the same for the Cache. Use your computer for a day or two with these settings. If your games are stable you can try going further to -125 mV for each.

Do some Cinebench testing. Many users with similar CPUs get their best results with the cache set to an offset of -125 mV and the core set to an offset of -175 mV. Run something simple like the TS Bench 960M test when adjusting voltages. If this test reports any errors, that means your CPU needs more voltage. Any blue screens while gaming, use more voltage.

At least memory speed data is correct!

Stay on topic. Memory speed has nothing to do with the undervolting question that was posted in this forum. Post any memory related complaints in the Memory DDR forum that @Bogus5 created.

Memory DDR

There is a Memory DDR information in the Turbo FIVR Control section, but it does not correspond to the truth. The installed modules are DDR5 5600 MT/s.

Yes, sorry for your inconvinience.

I cleaned it in November/December of 2023. I've also changed thermal paste on CPU and GPU, but it was some cheap paste I got from local store (didn't have time to wait for the dlivery), so gonna buy some PTM and will check out if it helps.

You thermal numbers are really weird. Its too hot for not that high load. You may have some trivial issues or not (the second option is not good and will cost you some extra money).

According to this video

You have a compact cooling system that has four screws for each CPU and GPU area. That is good.

When you do a profilactics it is a good practice to change thermal pads as well. You might have old ones under degraded condition, that fact could never be easily noticed.

As for thermal pads use Laird Tputty 607 or newer (if such exists) https://www.laird.com/products/thermal-interface-materials/liquid-gap-fillers/tputty-607. When use that kind of pads you don't care about thickness at all. And what's more important it does not bring to not a tight clamp.

Your main thermal component for CPU and GPU should be PTM 7950 of course.

Now two words about "a second option" which is not likely but not good at all.

You could have one of your heat pipes broken or disfunction. If it is that, it is useless to apply paste and pads, it just give you nothng.
Heat pipes info here

The point why i'm telling you that is that. You have told you reapplied thermal paste 3 monthes ago. It is too early to give you such a bad temperature results.

So finally it could be:
- bad or cheap thermal paste you applied (instead use genuine TPM 7950 together with Laird Tputty 607 or newer)
- not well tighten all screws on cooling system when assembled (could be regulated)
- cooling system has a curvature (need to be accurately fixed)
- last but not least, one of your heat pipes broken or disfunction (it should be diagnosted and tested at first, you may find how-to examples on YouTube, if it is proven faillure you should buy new cooling system for you notebook model)
