Hi @Klem :),

 

I would like to overclock my laptop Acer V3-571G 73614G75Makk with a GT640M (DDR3 ; GK107). I use Nvidia inspector to overclock at +135MHz (performance level 1 - p0) but i would like overclock more for my recent games but with a stable overclock :/. My bios is there : https://global-download.acer.com/GDFiles/BIOS/BIOS/BIOS_Acer_1.13_A_A.zip?acerid=634864833429483066&Step1=NOTEBOOK&Step2=ASPIRE&Step3=ASPIRE V3-571G&OS=ALL&LC=fr&BC=ACER&SC=EMEA_13

 

The Bios version is 1.13. Would you like to explain me what i have to do to overclock my laptop please and send me the bios mod ?

 

Thank you very much

 

Mathieu

Hi!

You can send me your file backup of bios in PM.  For creating backup of bios use attached program. Unzip attached archive directly on the Desktop and run the program as Administrator (right click mouse). Program will create archive "results" directly on the Desktop. Send me this archive "results" via PM or upload it to any fileserver and send me the link.

Hi to all,

I just flashed the "HP K3000m - 80.04.33.00.2E - 'OC edition' on my HP 8770W, all gone right, but the +135mhz OC limit still's here :poke:

Tried to edit original BIOS, tried the other release "Nvidia K3000m - 80.04.3A.00.07_'OCedition'_rev00" but base clock kept 654mhz and OC not more than +135mhz :question:

what's wrong with my K3000m???

Hi!

Just try to compare vbios version in your laptop in Nvidia Inspector window and vbios version which you tryed to flash, before flashing and then after flashing. You will see that version doesn't change, even after flashing. It happen because in your laptop placed two different vbioses. Real vbios it is a part of main system bios, and therefore  it can't be read or flash with Nvflash utility. Also, your system bios is strong protected from write any modified bios.
So, in your case only hardware SPI programmer can help.

Thanks for your fast reply! I saw another old topic where a guy succesfull flash his K3000m on a 8770w, I tryed as him to reinstall various drivers but still haven't results... can the newest nvflash be the problem? (because it run on Win10 cmd instead of DOS)

It is that what you meant? In the meanwhile I flashed from DOS with an older nvflash, upgraded notebook BIOS... I don't want to give up, this K3000m is really underclocked respect it's potential, at least i'll probably use an hardware SPI programmer...

Hello, I am new to the forum.
I was looking for an answer to the 135MHz blocking problem. about half a year.
I see that I was able to find a solution through my friend Klem who can modify the rom file.
Is not it a big problem for you to modify my rom?
I have an old EliteBook 8570w with k2100m.
Below is the rom file and screenshot from Nvidia inspector.
If rom works please ask for bank account number or paypal to give you a small subsidy :)

Hi!

Why you use MSI vbios, for your HP laptop?

When I bought the card it was this bios and I did not change it because everything worked as it should be. :)
It is possible that the previous owner has modified something or the computer's bios are modified.
Although about a year ago, from what I recall, I updated.

ps. I have a small problem with the record.

I do not know how to save this vbios.
Previously, when I was editing there were no problems with writing.
Although I did it a long time ago but I have nvflash under dos and there were no dilemmas.

I remember a long time ago and I had a version of nvflash for dos which had no problem with this ID.

 

"Checking for matches between display adapter(s) and image(s)...

Adapter: Quadro K2100M        (10DE,11FC,103C,176B) H:--:NRM  S:00,B:01,D:00,F:00

WARNING: Firmware image PCI Subsystem ID (103C.197B)
  does not match adapter PCI Subsystem ID (103C.176B).

Please press 'y' to confirm override of PCI Subsystem ID's:

NOTE: Exception caught.
Nothing changed!


ERROR: Update aborted"

 

It's strange because what I gave previously was the rom of my card.

Yes, just try to use another Nvflash versions.

Hi,
I have read that I can't unlock and flash HP 8770w Nvidia Quadro K4000m vbios, because there is also a vbios stored in the HP BIOS. 

Also tried to read, modify and reflash the vbios -> no success.

Could HEX editing all the 601 mhz values(the default clock for the K400m) to like 800 in the HP BIOS result the card to run on higher frequency?

I have successfully found the hex values to search and edit by comparing the original and the modified vbios. I have the HP BIOS + flasher. 

In the vbios the hex value stored in 7 places while in the HP BIOS I found more than that. Is it even a good approach or I'm just going to brick my MB?

Hi, thank you very much for providing these.

 

Can you tell me if using these modified vBIOS I would be able to undervolt my Clevo GTX 680m SLI?

 

I'm having some unstabilities when under maximum load and wanted to try undervolting to see if it was a problem with power since temps are at a reasonable 85C.

 

Thanks in advance

I found a way to write vbios on my card.
It is best to perform a usb drive or memory card as a boot disk.
Record on it NVflash for dos version 5.163.
And upload from the dos this  vbios with commands:

nvflash --protectoff
nvflash --overridesub new.rom
nvflash --protecton
 
The K2100 works perfectly at 8570w and you can manipulate frequencies.
Thanks again Klem;)

Hey everybody, I want to undervolt my Clevo GTX 680m to reduce heat and power usage and maybe get a few more FPS due to temps.

 

By what I've read Kepler cards don't support voltage/frequency curves so I should use voltage offsets. Is that so or should I be able to use the curves?

 

Also, when I try to apply the negative voltage offset on MSI Afterburner it resets back to 0 and nothing happens, and using NVidia Inspector the voltage section is grayed out so no go there as well.

Do I need a modded VBIOS to be able to change voltage?

 

Thanks in advance

Pablo

      I have tried to update nvidia drivers of my notebook ge72vr6rf apache pro. The only drivers that works are the ones provided by the msi. The problem is that they haven't updated those since 2016 and I can't play newer games. 
       
      Some say you need to mod your 1060 drivers, which I have no idea how to some says you need to update the flags in ini files. So please help me
       
      Thanks for your time.

      Hello, I've got a Dell Precision M4700 with a 3940xm. I've read that in this particular CPU and laptop model, the bios is locked because the stock settings are considered an overclock. As-is, the core temps on the CPU do reach up to 90-100. They seem to spike up and down a bit when benchmarked with Intel's Extreme Tuning Utility, but they certainly do reach over 90C. Is there no way to unlock this bios (version a18, though a19 is released - I haven't updated yet, should I?) and even if there were, would my only option be a heatsink mod on top of that?
       
       
      edit: I've mistakenly posted this under Desktop & General Hardware, perhaps a mod could move or delete the thread? Apologies!

      Hello, I've got a Quadro M2200 (GPU: GM206GL-A Revision A1, and MxM 3.0a Maxwell card) with the following bios: 84.06.76.00.1C
       
      I've read that this card is very similar to the GTX 965m, but that it has been underclocked considerably. It seems to be a good candidate for unlocking since I hardly see the temperature exceed 70C as-is. I'm requesting help with this - I'm not sure if it's possible to simply flash the vbios from a Dell GTX 965m (MxM 3.0a) or if some type of edit of the card's current vbios would do the trick. I'm hoping someone could help me out with the specifics of doing such an edit if that's the case. 
       
      Thanks!

      Hello Everyone,
      I am an owner of MSI GT70-20C and my GTX770m gpu i now dead.
      I have a question and i hope someone will help.
       
      I have ordered GTX 970m 6GB DDR5 and i cannot find the exact vBios for that graphic card.
      My current bios version is: E1763IMS.51B
       
      Thanks in advance,

      I own an Asus Fx504-gm laptop with an 8th gen i7 and nvidia gtx 1060. I ve been having issues with random hard freezes and I later found out that absolutely anyone with this exact model has the same issue and not even Asus service can fix it as they just replace every component and the problem persists so my guess is that this is software related.
      I ve been noticing that I Always hit power limit(I monitorised it with afterburner) and so I have power limit throttling. The thing is, for this laptop the power limit is locked and I cannot modify it.
      My last resort is to try a modified bios that can unlock the power limit slider. My question is: Is this possible? Are there any modified bioses that can unlock the power limit or the only way is to unlock it via the motherboard? If so, where can I get a reliable modified bios for my laptop and how can I check compatibility? Thx.
