Hello
I have Monster Tulpar T7 v18.2 with z370 chipset, 9900k and rtx2070 mxm with 115w TDP. It’s clevo barenone ( I thinkplease google it )
I want to do shunt mod to that graphic card for higher tdp for better performance if it’s possible.
When I’m playin game I always see pwr cap at 115w and card throttles it self.
For this card, anybody done that before? How much W this card handle and how much performance gain? I’m really noob about electrical things. So i need step by step detailed info and pictures if possible.
Thank you.
EDIT - i just did itCheck page 4 for simple results
Thank you @seanwee![]()

Instead of a shunt mod, you can increase the TDP in the vBIOS - http://forum.notebookreview.com/threads/mobile-pascal-tdp-tweaker-update-and-feedback-thread.806161/
-
It Requires a bios programmer for write a modded vbios, isn’t it?
Also I read about black screen issues who try that on rtx cards, is that true?thewizzard1 likes this. -
The card can handle up to 150w, same as 2080, as layout is the same.. Only solution is shunt modding as TDP tweaker will give black screen.

The card can handle as many watts as the cooling can handle. You'll run out of voltage control before the power limit is exceeded. Shunt modding is definitely a better way to circumvent power limitations than vBIOS modding. That has worked extremely well for me. I am not sure which resistors to shunt, as I have only shunt-modded desktop GPUs and my Tongfang turdbook GPU. Maybe @Khenglish knows.
-
Thanks for info. So i need details about shunt mod for that sweat extra 35w. As i said im very noob about that electrical things...
-
Thanks for reply, this is what i tought. I am looking forward for the detailed guidance of you computer experts.

And
so can you explain step by step what i need to do please? -

Put something if similar resistance in parallel with the shunt resistors to change the values. The circuit will notice if they are out of balance so you do them all.

Have you checked the likes of digikey?
Have you considered how you are attaching them? -
Yup, won't work with RTX 2000 cards.
Layout may be the same but it has two less power stages. I've determined that it can't handle 150w safely and even my current suggestion of changing R005 to R004 shunts (+25% pwr lim) will necessitate extra vrm cooling.
Desoldering the stock ones and soldering the new shunts is the best way.NORD likes this. -

Certainly clean to do it that way considering the pad layout and shape.

Hi,
For 2080RTX card what resistors need to be replaced and for what size?
thx -
Meaker@Sager Company Representative
The ones above and you will need some skill or a place that can solder them.
-
Where can I find resistors for 2080? I am considering to upgrade my laptop, my good friend is an ex dell engineer - who makes my mods come true - so changing the resistors is not an issue, however the big questions what type you propose to buy and from where I can order them. Thx a lot!!!
-
I wouldn't recommend my method, since I just desoldered all 3 shunts on my 1080 and just shorted the bridges with LM to test whether it would work. This was a quick and dirty way to see whether the concept was viable. And since it worked without locking the cards into 2D clocks or burning my VRMs, I just kept the LM on there.

What shunts are proposed to be replaced on the 1080gtx? And the million dollar question, where I can order from? thx
-
Hmm, I can't find the ones that I desoldered, but I'm certain they are the same as on the 20x0 cards (0.005 Ω)
On GTX10x0 cards you have 3 RS', one at the top front near the vrm and power connector and two at the back. One resistor is for the pci-e power and the other two are for the 8-pin from what I remember.Papusan, Mr. Fox and Spartan@HIDevolution like this. -
Is it safe to just remove them? or replacement is needed?
-
Well, like I wrote, I wouldn't recommend doing it this way. If you remove the shunts altogether, it will send the card into 2D clocks for sure, since there will be no connection.
As mentioned, I just wanted a quick and dirty way to test and luckily it worked. Think it's going towards a 2nd year now with the shunt mod.
Problem with the LM is that you have a lot of small SMDs nearby, and LM is conductive and eats solder. So prep and masking is needed.
A better way would be to desolder them and apply a silver lacquer or circuit pen to bridge the connection. That way you can undo it and resolder the shunts, should it be needed.Papusan, Mr. Fox and Spartan@HIDevolution like this. -
I would definately avoid your method (sorry to say). If it is safe to remove the resistors, I would connect them with very thin wire. My friend has all the pro tools, he fixes stuff under 500X zoom scope, so technical point of view I see no issue. The big question is it safe to remove all, or smaller replacement is the right way...jc_denton likes this.

If you just totally disconnect the shunts with nothing the card will be open circuit and won't do anything
-
You misundestood me.
1) take off all resistors and short with wire
2) replace with smaller resistor
thx -
Meaker@Sager Company Representative
A 0 resistance will freak it out, so don't solder/wire mod it. A lower resistance shunt then go with half.
-
Thx, and could you help what type I need and from where I can order? thx

You can buy resistors from places like Mouser and DigiKey. This is the style of resistor used on my TongFang turdbook. It may be the same on your GPU.

Thank you Sir! I am still planning an upgrade to 2070/2080, meantime I would check an upgrade on my 1080

Exactly, best go reputable for this sort of thing.

Hello again, i know it been too long but my ressistors just arrived lol
İ just change 2 of my r005 resistors with 004 ones. Looks like its free about %10 boost. TimeSpy graphics score now over 9k, userbenchmark graphics score %107
also its about +10c gpu temp
Thanks @seanwee for everything.Attached Files:

Well not free in terms of power
-
And heat lol true, true...
-
Meaker@Sager Company Representative
Still if you can cope with the temps it is a nice boost.
-
Yep. Also i made that bencs with my old ''auto OC scanner'' settings only for compare results. I think it have more potential than this results with better OC settings plus cooling.Papusan likes this.

It becomes a fine balance of voltage and frequency.
