Mobile Pascal TDP Tweaker Update and Feedback Thread

You need a programmer to bypass nvidia's security rubbish
The screenshots you have there with the wire are very old, that's not needed anymore, even though that's still up on some ebay listings it's not what you'd receive. And the MSI 1070 doesn't cause EC issues.

 

It seems like everyone is using this on MXM type cards.
I have an Eluktronics MAX-15, with RTX 2070.

Here is my BIOS file: https://1drv.ms/u/s!AuqwBZb5n5Jqhv55MAYcNnvfIZ24UA?e=gXbj3Q

I get this when loading my BIOS:

Is this gonna work? I don't want to bother ordering the clips and 1.8V SPI programmer if it's not...
I want to boost it to ~130W.

 

I have the exact same problem with my Recoil 3 from PCSpecialist (Tongfang GK7CP7S). i7 8750h/Full 2070. I didn't try my luck and didn't touch anything yet since I'm using my laptop for work at this moment. I'm really curious about it. Let me know if you try it someday !

 

I'll try it if Coolane will have a peek at the BIOS and confirm? Im pretty sure I can borrow the SOIC clip and SPI programmer from a friend.
I'm going to add some 2mm tall heatsinks to all the heatpipes, should be possible to run up to 150W sustained under load, IMHO on this laptop, but I think 130W will be safe.
It would be nice to just unlock the power slider and keep the default at 115W in case I were to play a game away from a cooling pad on a desk.

I already got the #6 high score on timespy for a 9750H/2070 combo by having the laptop upside down and the bottom case open, no power mods.
I figured why not go all out and power mod the GPU. )

I get an app crash when I try to save a BIOS.
I'm hoping to unlock power limit control.
All did was set limit = 132000 and select "Adjustable" and click "Save".

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

From my experience, the save crash occurs when you select a power slider option. If you don't touch it and just change the target and limit options, you should be able to save.

 

Hi bro, I got this laptop for quite cheap off ebay, same spec and same model however my gpu scores are terrible. I believe this is due to a power limitation in the earlier bios made for this motherboard. I have bios revision N 1.03 yours must be newer.

As you have access to pc specialist drivers (you bought the device from them) can you send me the newest bios, if it's available?

I am literally going to try this power mod, I'm pretty sure it won't work and you'll end up with code 43 but first I need to fix the terrible gpu performance I'm getting, these are my userbenchmark scores atm: https://www.userbenchmark.com/UserRun/26134901

I just about get it to normal 2070 levels with an insane overclock, obviously do not want to run it like that forever

 

Sadly there is no bios under download section of the account, only drivers for display and wifi

 

Well it looks like I can't do much unless you have a programmer? You could possibly extract the bios. If you don't want to that is perfectly fine too

 

I just checked, and I have the N1.03 bios version tho. The problem might be elsewhere imo

 

Damn, I really hope it's not that command center it's running. Could be possible it's limiting the gpu core.

 

i just noticed there is a Vbios update on msi website for GE73VR 8RF...
https://www.msi.com/Laptop/support/GE73-Raider-RGB-8RF#down-firmware
can be the bios modified before flashing it? will it be safe to flash?
i found they put some guide how to flash it, and now i wounder if it will work with modified bios

 

Thanks for the info.
I wonder if it will work?
Anyone have a link to a thread on hex editing BIOS if I need to do manually?
I was able to hex edit my regular BIOS to unlock menus...

 

It seems like @Coolane took is modifying some part of the bios that should not be...?
The text is changed from PLEASE POWER DOWN to PLEASE......


But it also makes this change:


It seems like it identify 00058c60 04 & 05 as the TDP limit, and 08 & 09 as the TDP default
because I changed 115000 to 130000 and the changed DEC value is 49464---->64464 exactly 15000

My question, is why is 0002cb50 being changed?

 

Ah-ha, I figured it out. He is editing that text string to correct the checksum. Clever.
So, on the 00058C6 changes, do these look correct for TDP values? Will they unlock TDP control in afterburner?

 

Since something was modified in the vbios, you need to correct the checksum, otherwise it would not work at all (card would think it's a unautorised vbios)

 

These changed value will not allow you to take control of TDP, it might work and enable the card to pull up to 130W, but it could also not work, on some vbios it even seems there is two time value that correspond to TDP value/control like on Quadro RTX vbios ionising_radiation sended me

 

Thanks. Do you have any comment on the 4E 56 at the beginning of my bios?
Someone was saying the header needs to be 55 AA

I am guessing i should leave 4E 56

 

Try with and without, it might prevent a black screen

 

If i change 4e 56 to 55 aa, do I need to do manual checksum correction?

 

Last question, are people flashing the bios chip in place, or desoldering? Id like to flash in place if possible.

 

I can be your tester bro, got a skypro right here, just tell me what to flash and I'll be on my way

BTW flash via Skypro or just the RTX rom via NVflash64 bypass ID

This is because on most machines the RTX rom is on the bios chip, so we need to force flash to allow it to work sometimes. NOT ALL TIMES THOUGH! My HP Omen 17 flashed the 190w rtx 2080 vbios from the alienware 51m with the modded nvflash.

You just need to make sure the checksum is valid otherwise it will not allow you to flash!

 

you remove some byte (like 10 or 20 lines, I don't remember right now) up to where you see 55AA, for checksum, I think you shouldn't correct it after deleting lines at the begining, try and you will see
With the right tool (compatible with 1.8v eeprom) you can flashing without desoldering it using a clip

for exemple on a random pascal vbios, my first occurence of "55AA" is at offset 00000A00

 

Does our laptop have a vbios chip or is the vbios embedded in the bios chip? Past RTX laptops I've owned have it embedded in the bios except for razer...

 

I don't know, is this solder on the board ? if so try to read every eeprom, if you have one with only 100~300kB used and something that refer to nvidia on first decoded line, it should be it.. nvflash can also indicate which eeprom it can read if I remember correctly.

 

Im not sure you want to flash my ROM, we have a different chip?

 

Mine occurs here: it's way down there. Does not seem right to delete so much of the BIOS file?
Looking at the text is gives me the "feeling" it's the beginning of the file, but I would be deleteing like 1/4 of hte bios file....


Here is my BIOS, if you don't mind having a look:
https://1drv.ms/u/s!AuqwBZb5n5Jqhv55MAYcNnvfIZ24UA?e=Q5cWv0

 

Ok, I’ll take a look. All rtx 2070 vbios by tong fang are the same as long as they are Max-P (115w tdp)

 

Yep its a tongfang 115w.

 

yes that's it, delete everything before 28600 in order to have a "55AA" vbios

 

I believe you are correct, that line is the actual start of the vbios, I have seen this in the past when flashing with a skypro.



This also proves @Liddo-kun that our vbioses are exactly the same. You can feel free to modify it now, I'm not a hex master like you guys

 

Can confirm mine looks exactly the same as well

 

so, you gonna try it?
Im waiting for some thermal paste and 2mm heatsinks to arrive.
I may just do resistor/shunt mod (does anyone know the resistor size?)

 

Yep, waiting on you to change the values, etc. I’ll make a full dump of my bios and ec before flashing though. Just incase things don’t go to plan

don’t really know about shunt modding in laptops, you can try and look for the resistors.

 

I ran a shunt mod on my GS75 for a bit before the solder came off. Going to redo the mod when my new soldering iron arrives.

I didn't get much performance boost as the power brick was capping out at 230w

I got a 10% improvement in firestrike graphics with the shunt mod.

 

I want to find out the resistor size without taking it apart so I can order it from digikey....
Someone have a good pic of a tongfang 2070 with HSF removed?

 

https://1drv.ms/u/s!AuqwBZb5n5Jqh4Ak0PKFKgaXy94PUw?e=XFhclf

You can try those....
Tweaker-Modded is the one outputted directly by this app, with TDP changed to 130w.
Tweaker-Modded_55AA_NO_CHECKSUMCORRECTION is the same as above but all the data in the file before 55 AA is deleted.

AS you already know, be prepared to have system boot with black screen so have your stock bios ready to flash back.

 

for shunt mod you need to add a specific resistor value, otherwise it would throttle to 300MHz all the time if the resistance is too low

 

I just bridged the shunt using solder and it works fine.

I know that's not the case with desktop cards but laptops use a different controller which may be as picky.

 

First one doesn’t work, leads to error 43 and vbios error message on startup saying no n18e Max-p or max-q vbios detected

ddu driver removal and reinstall still leads to error 43. Some protection somewhere limiting the tdp mod.

I’m gonna try the next vbios which starts with 55AA

 

Could you please tell me which vBIOS you used for M17x R4? Also did you remove the IFR header?

 

Finally went through this TL;DR thread..... Cos now I have the problem of modding the vBIOS for the buyers of my GTX 1060 and GTX 1080.

Both of them has Alienware M17x R4, and quite sadly it appears that on M17x R4 the card will not work unless there's IFR header present......

Attached is a vBIOS that works for the GTX 1080 mxm on M17x R4, From my experiement only the vBIOS beginning with 4E 56 will work on M17x R4..... this is annoying cos I cannot remove the header to get the modified vBIOS working.

This vBIOS has rated TDP of 200W and is definitely too much for M17x R4.

Also does anyone have success with Desktop pascal Cards? Tried to underclock my GTX 1080 Ti FE and black screen is all that I got, regardless of the presence of header

@Coolane @TheQuentincc

 

You can't edit frequency in the vbios, the closest case of such edit was prema where he managed to have frequency of a 1080 on a P5200 vbios (check his twitter account)
Does the attached vbios works at 100% on the M17X R4 ? you want to decrease the TDP of the attached vbios at which value ? Isn't the M17X R4 limiting MXM power by itself ?
According to board schematic, it seems like MXM PWR_SRC is rated at 10A (supposedly max) so 19.5V x 10A = 195W max

 

Yeah I don't wanna edit the frequency. The time of extreme OC/ tweaking laptop to the point of smoking is long gone for me......
I have tested working on M17x R4, powers on to desktop. have no problem installing the modded inf. Don't have the proper heatsink so can't test much in detail. But certainly 200W is a bit too much for it..... I'm selling my GTX 1080 mxm and I certainly don't wanna buyer come to me a few weeks/months later complaining abt his laptop/card broken. M17x R4 was designed for those 100W MXMs and there's certainly not much headroom for it.
I wanna limit it to the Max-Q level, like 110W-132W

As for the GTX 1080 Ti, I wanna it to run @225W-250W, I have MSI Aero

 

Second one didn’t work either.. code 43 but no vbios error this time and laptop seems to boot the first time too.

I believe something else needs changing... what do you recommend @Liddo-kun?

 

Keep trying that second one. You need to do some INF mod to re-install the driver to fix the 43 error.
See if you can force the drivers to install manually. (Have disk...) option. Know what I mean?

 

Hardware ID didn't change though and driver installs perfectly fine, will need to source modded drivers, I'll try the have disk method

 

Nope still does not work, damn
