Extremely weird Asus laptop 4090 Core clocks

[Lucifer_X_Devil]

I am seriously surprised that this hasn't been brought up for almost 2 years. What are Asus users doing?

Model G834JY
Scar 18 4090 (2023)
BIOS 331, Windows 23H2

Throughout multiple windows reinstalls and testing multiple Nvidia drivers, the Asus's laptop 4090 boosts extremely weirdly past 50 to 55 degree mark. Without an overclock the average voltage drawn stays above .800V but the moment you OC the thing, it drops to way below .800V boosting the core clocks terribly. An example is Timespy GPU test 2, where other OEM brands hit over 2200-2300Mhz , the Scar 18 with a +240Mhz stable core OC and 1100 MHz stable memory OC, hits between 2000-2200MHz..... What is this Asus? My temps don't cross 61 degree Celcius in a well air conditioned room. There is literally no need to pull down the clocks this much. And please do not blame this on Nvidia when your own BIOS hardlocks it. Only way people have been able to get better performance is by literally shunt modding the laptop and that too has been probably done by one or two people with guts.

This is literally the highest score I have seen from the same config and I am ****** sure that is shunt modded too or using a custom BIOS with likely a tweaked IMON slope. Just give us an advanced BIOS and hide it well enough so normal guys can't figure it out. 

I am an overclocking enthusiast. In the comments please don't mention stuff like, "This won't convert to real life gaming performance". I do not care about gaming performance.

It is understandable that Asus cannot reach the same level of performance as XMG with it's liquid cooling, but ****** lenovo is performing better with 23k and 24k graphics scores in timespy while Asus laptops are crawling at 21k or 22k. 

The following tests were done in a different environment so the temps are a bit higher:
You are looking at the average GPU core voltage.
NON OC

OCed: 


Average Boost of Core clock is much much lower compared to other OEMS.

Things I have done for max performance....
Laptop elevated @ quite a steep angle with IETS Gt500 running at max 5000 RPM
dgpu mode obviously with fans maxed out at all times

Ambient temps make the silicons go down to lowers 40s and lower 30s for CPU and GPU respectively.

Nvidia Control Panel settings tweaked for max performance

MSI afterburner: Core +240 Mhz, Mem +1100MHz, undervolted at .850V (undervolting doesn't make any difference in Asus laptops unlike other OEMs.....)
Nvidia Driver version 566.36.
Other drivers tried 576.XX, 528.49, 537.XX
528.49 was to unlock power slider in MSI afterburner and disable Nvidia Platform controllers and Framework which is responsible for Dynamic Boost. 
This was done because even at 175W the performance of these Asus 4090s is comparable to running at 150W!!

Please @Anbby_ROG if you are reading this, push Asus for a fix. I really do not want to hear, "This is how the laptop was designed", from any other moderators. Just please allow it for the extreme enthusiasts in a hidden way with a guide. 

I really hope to receive a positive response and am willing to cooperate for further Timespy or 3d mark testings until 18th May. Have a nice day.

Sounds like you're basically moaning about how GPU Boost works. You could have condensed this whole rant by showing other mobile chip data from other vendors.

 You can also go on timespy's page to look up non shunted 4090M results. 

[Hipflask]

Why would I want to look up shunted results at all? Not even sure why I'm wasting my time with this. 

You can see from the average temperatures the HW has likely been modified. How does this help your case at all? It's 3DMark HOF?? Three of those are from the same person...

Thermals are massively important when it comes to sustained clocks. You're taking sweaty runs with most likely modified or tampered hardware, or at least very low ambient, and trying to make a case for yourself. You'll need something more conclusive than that - nothing out of the ordinary there.

[Lucifer_X_Devil]

Why you are replying to this, Ive no clue. The results Ive shared are all stock hardware with OC. I e run mine with similarly low ambients. The average temp is what matters and these boost clocks boosting lower has nothing to do with temps. Already tested that. 

https://www.3dmark.com/3dm/133366888

And this above result is a tryhard GPU centric run. 

My temps are lower than 3 of those in the screenshots you've compared. 

Idk why you are so concerned about 3 results being from a single person. The guy literally benchmarks different laptops from same or different brands. 

I would request if anyone here viewing this, owns scar 18 or 16 laptops (4090) from 2023 or 2024 to please report if they see their core boost clocks ever hit anywhere close to or above 2300 MHz. Make sure your hw is not modded or it won't be conclusive enough for some.  

Also please post your runs here, as it will be educative for me as well 

[Hipflask]

It's NVIDIA's GPU Boost. Also where do you live to get less than 60C underload? What exactly do you think ASUS is doing to alter GPU Boost behavior? NVIDIA don't take kindly to such things.

[Lucifer_X_Devil]

I think nvidia is exactly trying to work as intended since the same driver is being run on all devices. Even if Im avoiding 576.XX for obvious reasons. But Asus BIOS is somehow limiting the GPU boost absolutely not allowing it to hit 2300 MHz in any scenario during timespy unless the first cycle of a custom GPU TEST 2 run loop or if you are running the demo which uses a lot lower power. Ive done my best, the devices just have a lower boost clock. I have swapped to tongfang vbios, I can confirm it is not the Vbios, something else maybe Asus's bios is limiting it. They really just need to allow unlocked settings for enthusiasts. Btw this same behaviour is seen in razer laptops too. Understandable for em cuz they are way thinner. 

I need Asus to answer what they are doing and why they are doing. Are they using crappy Vrms? I just cant put my finger on the issue. Maybe it throttles when it goes over 175W? 

As for the low temps on mine, it is just raised up at a steep angle with iets 500 running directly in front of an AC. 

In India your average gou temps will be 64 degrees without being directly in front of AC. 

Btw there is a timespy scar 16 score on the internet that is so high (24k) that it is probably shunted. If only we could get in contact with the dude..... solely to figure out how he worked around this limit.

Right.... become pretty obvious, ain't gonna get any help here. 200+ views, 1 week, not a single reply. I will wait another week after which the post will be autoclosed. G'day ASUS.

[ElectroStingz]

Hello,

I don't have a 4090 but yes once you hit 175W (or specified TGP depending on the ASUS model) it will start throttling as that is the ASUS config for the shared CPU+GPU power limit. (shunt mod helps on that part)

Out of interest are you using armourycrate in turbo mode / manual with maxed out sliders? (or other alternative)

[Lucifer_X_Devil]

G helper, pl1 pl2 175W on cpu. 

Best performance mode, efficient aggressive boost. I ditched armory crate long back.

It needs to stop looking at the laptop hitting the power limit and start looking at how much thermal headroom it has. Only downclock past a certain temp that is like 5 degrees off the 87°C limit

Maxed fans on all 3

Dynamic boost 25W altho it doesnt do jack.

Afterburner +245 Core, +1200 memory
