Mobile Pascal TDP Tweaker Update and Feedback Thread

when I clicked the “Remote” button, I got a bios that runs 55AA . I think this will not work 99%
PS I already wrote above. when I try to install the mod driver apply to zero, I get code 43 - the vga stop working

 

Just upload the images to the forum, dont use external hosts.

 

For me GSync doesn't work because of a bios whitelist by the GSync cookie however it might work for you depending on how the firmware has gsync incorporated.

As for modified drivers yes you'll need to use them each time as the ID is not in the stock driver.

Thanks bro. everything is working. I glad))
This time zeros does not stop vga .

 

Hey guys. Is it possible to mod 115W TDP limit of Clevo MXM RTX2070 card with this tweaker?

Do i need hardware flasher like ch341a to do it? Maybe someone can share experience, would appreciate it.

 

ch341 not .,use nvflash64 --version ,.chip name + allowed voltage
skypro is good or similar ,frst page here ,,ch341 not compatible to wbound xxx40eq or similar ,,some need 1.8V max
.P

 

You cannot flash modded vbioses with nvflash.

So am i good to go with ch341a programmer with 1.8v adapter?

I have the following bios chip on the card. WBond W25Q80EW 1.65-1.95V 8192Kx1S

As far as i understood - i just need to hardware flash modded bios, based on my original with changed TDP.

 

need programmer for any mod and need programmer support "WBond W25Q80EW"
skypro etc or from first page ,,1.65-1.95V is 1.8v adapter
ch341a is 3.3 after mod or 5v and not support this chip

 

Hi, I have MSI GS43VR with 1060 that almost constantly hits power limit, I swap thermal paste for a liquid metal and now temps are much lower (70-75C with cooling pad). I downloaded Mobile pascal TDP, extracted rom with gpu-z and edited 78W power limit to 110W target 115W max (GPU VRM is designed to 120W - info from MSI customer support). but problem is with regular NVflash I cannot write this modified bios and latest certificate bypass nvflash doesnt find my GPU. So Im just asking if this bios mod even make sense or I should try shunt mod instead or is there any other way to bump up that power limit.

 

You need to use a hardware flasher. Instructions are in the OP.

 

You need to use a Hardware USB SPI programmer such as the ones mentioned in this thread with a 1.8v adaptor and a SOIC8 test clip.

nVflash will not flash modded firmware which has also been mentioned a few times now as well.

This will mean you'll need to find the vbios chip if it's external to the main bios chip. Else if the vbios is in the bios chip your going to need to take more steps.

So, I've finally gotten my hands on a CH341A programmer, a 1.8 V adaptor, and an SOIC8 clip. Drivers are installed; I'm hoping to modify my Quadro P3200, Quadro RTX 3000, 4000 and 5000 (yep, I've got all of 'em, all as DGFF2 form factor), and see where we go with this.

 

Could you please update on results? So far i have negative experience with this setup by trying to flash modified bios by this tweaker for RTX2070 (MXM). The chip just fails to be read/write/identify via the clip.. Probably i will have to desolder it and solder back to flash.. However i have tried with mxm card out of slot, never tried inside mxm slot yet.

Appreciate photos of your setup also)

 

I can read off the chip perfectly fine under Arch Linux (kernel 5.6.10); for some reason, Windows refuses to work. I have read all that Linux is generally more stable for this sort of SPI/serial stuff. I plan to modify the VBIOS in Windows, save, reboot to Linux and write to the chip. flashrom is a straightforward utility, and Linux has built-in drivers for the CH341/A programmers.

 

As for images:



The flash was successful (80 W -> 150 W); now to try to install it and see if it works. The black screen bug was not implemented; let's see what happens here. If this mod is successful, it means I don't need to perform the more dangerous shunt mods.

 

I have exactly the same programmer and adapters... However was trying to do flash under win.. What exact issues do you experience under win? Is it failure to identify chip error or FFF read or something else?
I have tried both asprogrammer and ch341 programmer - both with failure..

Maybe should try linux also..

What kind of vbios chip do you have? w25q80ew?

So no black screen on RTX series after mod and flash?

 

It simply fails to detect the chip, which is a WinBond W25Q80EW.

I haven't checked this yet. I need my notebook for a little work, so I'll use it for a little while more. I plan to import some graphite pads because I'm tired of repasting over and over, and I also have some real uneven temps on my CPU.

 

The graphite pads are also one time use, so anytime you remove the heatsink you need to replace them.

 

That's interesting. I was under the impression the whole selling point of graphite thermal pads was that they were reusable, and clean.

 

There are AMD gpu's using them and they tear apart when being removed.
And they require a perfect heatsink to die contact.
And if I recall someone used them and found the same thing, they will tear apart when you remove the heatsink.

 

Yes, I was the one who said that.

1. It performs as well as liquid metal if you have perfect contact. I lapped my heatsink to a mirror finish.
2. If you have good mounting pressure, the graphite pad will be squeezed very thin and upon removal it has a very high chance of tearing as it sticks to the corners. Even if you leave it as it is the temperatures will no longer be as good as the first time you applied it.

They are cleaner than paste of course but if you have to constantly remove the heatsink it would be very costly to keep using graphite pads. I'd recommend liquid metal, you don't need to clean up and reapply it, just re-spread it and top up the LM to compensate for the amount that sticks to the Q-tips when you reapply.

 

Just to be clear here:
The 1 use pads are the "Carbonaut" pads by Thermal Grizzly.

The pads that can be re-used are the "Panasonic Soft PGS+" pads.

 

Thanks for your insight, @seanwee and @Falkentyne. I'm generally very averse to liquid metal because 1) it's liquid metal: a poor, rushed application technique can lead to a completely broken machine, and 2) contact tends to worsen when the notebook it is used in, is moved around. I generally carry my laptop everywhere I go (still a college student), so I'm not fond of liquid metal.

I'd like to experiment with both the PGS pads as well as Carbonaut, because I am rather tired of cleaning and re-pasting my notebook over and over. Tearing it down is already an involved process (Dell Precisions have an inverted arrangement, so the palmrest has to be removed to get to the heatsink and the GPU), and I'd like to eliminate one extra clean-up step.

That said, any recommendations for a thicker, non-pumping paste is also appreciated: I currently am using CoolerMaster MasterGel Maker Nano (complicated name).

 

I carry my laptop around a lot as well and i've never had any issues with liquid metal. It was only recently that i switched to carbonaut because i was curious how it fares in laptops. As long as you dont apply too much until the LM squeezes out the cohesiveness of liquid metal will prevent any leaks.

If you want thicker pastes id suggest Gelid GC extreme, Kingpin KPX or Phobya Nanogrease extreme.

 

So, flashed the modified VBIOS on my RTX 3000, installed it, and (as expected), received a Code 43 error in Windows.

Rebooted to Linux, and GPU was detected by neofetch, but running Unigine Superposition failed with:

Code:

Failed to create OpenGL context for format QSurfaceFormat(version 2.0, options QFlags(), depthBufferSize 24, redBufferSize -1, greenBufferSize -1, blueBufferSize -1, alphaBufferSize 8, stencilBufferSize 8, samples -1, swapBehavior 2, swapInterval 1, profile  0)

Back to the unmodded RTX 5000, I guess, and time for a shunt mod... Yikes. Let's hope someone figures out a way to mod VBIOS power limits on Turing.

 

Does anyone know if there is a possibility to rise the memory voltage on Pascal bios with hex editing?
If yes could someone give a guide on editing it?

I used these on my RTX 2070. They match the already existing R005 on the MXM card

 

CH341A ? works ?? ,,not support this chip ,,need skypro etc

 

As he said, ends in Code 43 error, so it doesn't work, either there need to be more work done on the software side, or you need to do shunt mod.

 

So far my experience with the shunt mod has been very hit and miss. On one hand I've had my card pull 150W only to shut down a few moments during a benchmark, and I have also had my card PWR limit itself at 60W 1300Mhz. This, in my mind, has been caused by the limited TDP. Although the card is under-reporting its usage of power, it doesn't correct for it. There's something else going on with the mobile power limits and their boards. Maybe there is an external PWR monitor on the card that also needs to be shunt. it's hard to say for certain.

 

I've already received my 330w adapter and done some testing.

On my GS75, the EC is preventing the laptop from drawing more than 230w total, so while I'm gaming no throttling will occur, but when loading both the CPU and gpu the total system power draw will exceed 230w and it will trip the EC limit.

1350mhz is the "safe mode" clock nvidia sets on the 20 series, if you flash a max-p vbios onto a max-q card it will go into safe mode. An failed shunt mod (too low resistance) will also trigger safe mode.

 

Has anyone been able to use this to turn a boring 90w tdp 2060 into 115w ?

It looks like the board can handle up to 115w, but it's limited via the vbios..

Thanks for your input in advance guys!!

 

It doesn't work for Turing cards

 

yes it work, you don't need an expensive flashing device

 

Hey guys, can you please help me? I'm a laptop user. The model name is Aorus X5-V7. I backed up the original Bios before I started working. And I modified MX25U4033e Rom using ch341a. Then I booted up my laptop, and a black screen appeared, and it turned off a while later. I restored Bios to its original version to solve this problem. But still the black screen appears and turns off!

Please help me.

P.S. Grammar can be unnatural because of the use of online translation.

try to clear cmos your laptop too, disconnect power supply, battery and CR2032, reflash your 1070 vbios and retry to boot

 

I really hope you used a 1.8v Adapter.
If not you probably fryed your Chip.

 

if the "verification" is okay then that's not the issue, but I think you can't properly use a ch341a with no adapter on this type of power plane, it would be shorted and "disconnected" by windows

 

Ah never mind. I didn't read correctly.

 

Still not working...

 

did the verification is okay ?

 

Yes. But I think there might be a problem with the MX25U4033e. There is a possibility that it has been damaged.

 

If you write the bios and the verification is ok then this is not the issue, because verification mean that it read all the bios chip and compare it with the opened file, if the programmer can read it and read exactly what it did write before then your card can also read the bios with no issue.
I think the worst case scenario for you would be to flash the main bios using a dump (because I can't find bios file on gigabyte website), for exemple paying this guy the eeprom or only the file :
https://www.ebay.com/itm/Bios-Chip-...621576?hash=item5da86c3248:g:TD8AAOSwcF9UXpz2
Try to ask here too, guys here should know better than me your laptop :

The main bios of Aours X5-V7 are on this link
https://www.gigabyte.com/us/Laptop/X5-v7/support#support-dl-bios

I uploaded my laptop's vbios and main bios here
https://drive.google.com/file/d/1AdnxJVsshBeMXSuNm4qO6fqVkmX5_alU/view?usp=sharing

 

it's a .exe not a bin file ready to write on the eeprom on gigabyte website.
Is this your actual bios ? date says it's from 2018

 

Yes. It is actual bios.

 

Indeed the vbios is the right vbios for your laptop, I think you should make a thread in the gigabyte section to seek help, this is not the right place to talk about your laptop

 

Okay. It was for a short time but I was thankful!

 

I've given up on vbios modding entirely and have just been shunt modding laptops lol.

Just shunt modded a Zephyrus G with a 1660ti Max-q and easily got 1st place in 3dmark FS and TS.

I shunt mod using solder btw. LM shunt modding in a laptop is just asking for an expensive paperweight.
