EDP and Temp Thorttling

[OverBird]

Hi
i am using the laptop from aorund 2.5 years and i have now taken interest in the issue regarding CPU.
So i have i5-11320H heard that its like pc cpu but in laptop
GPU is MX450
So the 1 month back i have cleaned the fan of the laptop, before cleaning the alptop i had ran a Cinebench R23 for multicore got 2591. After i cleaned the laptop the score wet to 4091. I did another Cinebench before the post the scorehad reached 4747

But the main issue is that the CPU speed is around 3.7-3.9GHz (Turbo is 4.5GHz)
PKG Power is around 22W-23W (PL1 = 35W and PL2 = 51W)
Temp are around 80-90 or even 95 sometimes.


Posting The screenshots and log files(relevant one)

Hoping for the positive reply

Turbo is 4.5GHz

The max is 4.5 GHz when 1 or 2 cores are active. That drops to 4.3 GHz when 3 or 4 cores are active.

The log file shows some of the problems. There is lots of EDP throttling when running on battery power. The manufacturer has likely set a very low current limit to help protect the battery from being damaged.

When plugged in, throttling is sometimes caused by EDP current throttling and sometimes your laptop is thermal throttling because it is too hot. Poor cooling in laptops is common. If you replace the thermal paste, use Honeywell PTM 7950. Many other popular thermal pastes like MX-4 work very poorly when used in laptops. They can quickly degrade in as little as a week or two. That is when your temperatures will start going higher and higher.

If you fix the thermal throttling you are still going to have EDP current throttling. The Core i5-11320H does not allow access to any of the FIVR controls. You cannot adjust the IccMax current limits when the FIVR settings are locked out or not available. There is nothing you can do to fix these problems.

Can nothing can be done? THe DPTF trick might work?

What laptop is this?

Is it an Inspiron 5510?

I had one that I gave to my brother a few months ago and I replaced the original thermal paste with PTM 7950 in the first week of use.

Originally it could sustain ~28W in Cinebench under ideal conditions.

Now, under the same conditions, it sustains +37W.

The score in Cinebench R23 went from +5000 to +6000:

What trick is that? I do not know of any tricks that can solve thermal throttling and current limit throttling on a locked down H series CPU.

Is it an Inspiron 5510?

Its it Inspiron 5518 same as Inspiron 5510 but with NVIDIA GPU MX450
Under load it is working under ~22W. Thats a huge improvement.

What trick is that?

No thermal throttling but EDP Throttling is said to fixed in the article

EDP Throttling is said to fixed in the article

That article does not mention anything about EDP throttling. Disabling DPTF can fix some power limit throttling problems but I do not think that is going to fix the EDP current throttling problem that your laptop has.

It is easy enough for you to try the DPTF fix. Run another log file. Does it still show lots of EDP throttling or does it show lots of TEMP throttling in the log file?

Ok so after trying the DPTF the condition did not change.
But i am still getting TEMP and EDP. I am going to change the thermal paste, I have visited local shops here in India the fact is that they all are cheap thermal paste which is like 1 fourth of artic Mx-4 or myrofuze and the quality is like 30g-30g.

Also i saw EDP with PL2 throttling. My GPU has max temp 75.

The first thing to do is to change the factory thermal paste, as any quality compound will provide a good gain in thermal headroom.

I tested it on my Noctua NT-H2, Thermalright TFX, PTM 7950, and they all delivered a big improvement.

Thermalright TFX has performance practically the same as PTM 7950, but it pumped out in a short time.

I would rule out this option, as would Artic MX4 and Kryonaut.

The Noctua NT-H2 delivered performance slightly below the TFX, around 35W sustained, but performance remained slightly down after weeks of use.

The ideal is to use PTM 7950, but if that is not possible, another quality compound will solve the problem, with the risk of a drop in performance in a short time.

In addition to the 5510 that I had without a dGPU, I have already adjusted an Inspiron 5518 with MX450 for a friend.

After replacing the thermal paste, I adjusted the CPU power limits and undervolted/overclocked the GPU.

It seems like he got a new laptop, with performance much higher than the original and with lower temperatures overall.

I limited powers to 35W/45W for high CPU-only loads and 15W/20W (you can limit it to 20/25W if you want even more performance at the cost of higher temperatures) for simultaneous CPU+GPU cross-loads.

Can we overclock MX450? Max temp for GPU is 75. When both GPU and CPU are active more heat is generated as expected.

My PL1 is currently 35W and PL2 51W. But while running Cinebench the max CPU power is around 20W.

The good thermal paste here in India is overpriced.

Can we overclock MX450?

Yes, I use MSI Afterburner.

Max temp for GPU is 75. When both GPU and CPU are active more heat is generated as expected.

With PTM 7950 on the CPU and GPU, you won't reach 75°C on the MX450, unless the ambient temperature is very high and under heavy loads for long periods of time.

In any case, with an adjusted undervolt you will never reach 75°C.

You can also change the temperature limit with Asus GPU Tweak (I recommend up to a maximum of 80°C on this laptop), knowing that your keyboard will get even hotter...

With GPU Tweak, you can also overclock/undervolt the GPU.

My PL1 is currently 35W and PL2 51W. But while running Cinebench the max CPU power is around 20W.

There is no point in setting limits above what the current cooling capacity allows.

This way you will always be pushing the temperature limit and suffering constant thermal throttling.
