Shunt Modded Asus Strix Scar 17 (2023) 4090 7945HX

I just bought a cheap oled laptop for 680cad a vivobook, ran timespy and got 720 because of the single channel ram, pretty funny seeing your score as 37.1 times faster. wonder why theirs such a huge disparity

@seanweein the end what did you settle on score wise from your 4090 in timespy? where did everyone go

Broke 27k timespy graphics and 17k Port Royal.

I've just been lurking. Busy catching up with games and got a quest 3.

Why do you think lol

 

And I've gotten it a bit higher after a bios update allowed some more undervolting headroom.

 

[ryan]

lol..

 

nice.nice.

 

I want a quest 3 bad.  I heard from a few reviews it is really is a step up from the quest 2. Ill either get the quest 3 next month or suffice/suffer with the quest 2 tomorrow. its a win win. looking forward to playing half life alyx and re doing the GTA V mod mainly for exploring and messing around. Some fun games that run natively on the quest 2/3 and because its VR its like playing video games for the first time as a kid/teen.

Hello

Made an account just because of this thread lol

 

I have the same laptop and have been wanting to shunt mod after my warranty expires.

 

I just have a question - how can the laptop charging brick be pulling 400W when the max output it can do is 330W?

 

Won't this cause the charging brick to get extremely hot?

 

And would you be willing to list the resistors you used and where the shunt resistors are located? Would I be able to go to the same 250W GPU like you did on my machine?

 

This is insane and very awesome. I was upset the GPU was capped to such a low wattage. I hardly reach 70C+ on my GPU temps, it has so much room for potential

Chicony adapters are well known to be the best with a safety factor of 30%. That brings it nicely to 440w in this case though it does get very hot and will shut itself down after 30 minutes.

 

There are two different sized shunts on the other side of the motherboard, you only need to change the bigger one to R003 to achieve the desired effect.

 

 

70C+ on the gpu stock ain't exactly amazing tho, I never hit 65 pre shunt mod. Remember to respread the Liquid Metal and replace the thermal putty with a high quality one.

 

Don't mix regular Conductonaut with the Conductonaut extreme it comes from. There's enough in the laptop to respread.

First off, thanks for the reply! You rock!!

 

And yes - I don't ever go above 70C+ that is what I meant, like I hardly ever see the temps even in the upper 60C region. It stays about in the 65C region as you mentioned. 

 

And by bigger - you mean in size not resistance right?

 

Thanks again man. Such an awesome job

 

And yeah, that makes sense that it shuts off after about 30 min. I wonder if we can mod that as well to handle the higher wattage without getting so hot. Maybe a heatsink mod or transistor mod? Not too sure exactly what gets hot in a power supply - i always thought it was the transistors

Way ahead of you.

 

 

 

Gpu backplate cooler, passively the surface area alone is enough for daily 380-400w use. You can run 5-9-12v to the fans if you want to with a Type C PD Decoy trigger board.

 

 

 

[SolitaryMassacre]

Hell yeah. That is awesome. I kind of already do this as I have a loft bed and I strap my charger brick to the metal frame simply cause I want it off my desk. The frame helps dissipate the heat.

 

Since it works passively without the fans on, would this work a little better because it has more metal/surface area? A fan can be added later if needed.

 

I personally was gonna take mine apart and 3d print a new case for it with added heatsinks, but damn if that is working for you with continuous 400W draw - I'll just do this instead. Zip tie the heatsink to it and that would be it ha.

 

Man this is awesome.

 

Also, can I do the shunt mod without removing the CPU/GPU heatsink? You said the shunt resistor is on the other side of the board so I would think so?

 

I plan on doing a respread later but I guess I should/could just do it all at once

@seanwee I have been using intel for as long as I can remember. Im new to overclocking via TDP increasing with ryzen controller I was wondering if you could be a gentleman and help me get the most from my zenbook. I have it set to 30watts up from the 15w and the performance gains over stock are basically non existant wheras people on youtube are showing 30 percent gains by changing TDP. perhaps im thermally limited but I was wondering with the 5825u what a safe tdp setting is?

I've set the tdp of my 5600u hp ultrabook to 48w before. I got 50% gains going from 15w to 48w. You also need to increase the edc/tdc current limits to get the most out of the tdp increase.

 

Some laptops have STAPM aware power limits which are a headache as it will throttle when the motherboard hits a certain temp.

 

Vrms needed cooling at those wattages though so I put a vapor chamber and ssd heatsink connecting them to the main heatpipe. Running it at 40w currently. 

 

 

[ryan]

thanks, 48w seems to be the max found info on notebookcheck. I run stock and get 1400 in timespy with the TDP set to 35w I get 1450, am I doing something wrong I just set all three tdps to 35w in ryzen controller, I thought it was as simple as that per youtube tutorials

 

I just need  like 20 percent bump Im apprehensive about changing voltage, any safe suggestions

There's no need to change voltage, just power and current limits.

[ryan]

how do i change current limits and what value>?

I just maxed them out to 200A, manual settings in ryzen controller.

 

You may need to try older versions as the feature gets removed sometimes when they revamp the ui.

[ryan]

I increased the A and it didnt improve performance, for some reason going from 15w-25w I see a decent jump but going to 38-48w I see nothing 0 gains even while increasing amps. its possible i need an older version of the app, are their alternatives that actually work unlike AATU
