I've been promoted but can't attach files. I tried to DM them to you. But you can make your own custom vBIOS, google it, it's not hard. Use GPU-Z to backup yours first. You must use a working nvflash for your card (can't remember which). Search and read the flashing instructions for a Kepler Mobile GPU. Good luck!

Hola lo he intentado use tweaker para subir a 300 mhz de los 135 mhz de fabrica pero necesito liberar el voltaje de la gráfica pero no puedo hacerlo sin vbios ya que no quiero dañar la gráfica saludos.

You can't unlock voltages in a M6700, nor CPU neither GPU. I have a highly customized M6700 with a BIOS edited by myself, custom IFR's and a 980m (after a K3000m). Everything unlocked (CPU at 4,3 Ghz each core an reference clock at 100,3266 Mhz) and GPU overclocked to my needs, both core an memory. Changes in voltage are made by the laptop regarding selected speed. Values are greyed out in any overclocking software. You can modify Boost table/States or Clock States in Kepler Bios Tweaker so GPU will be overclocked before using Afterburner. It's risky, be careful. I could send you my modded BIOS if I weren't in pre-promotion.

In 2022, I wish you a thousand good things.
Please teach me how to unlock Bios to overclock Dell M6700 with 3940XM and K5000M.
I have difficulty and do not know who to turn to for help until today...
I don't have much money to upgrade another laptop while needing a higher configuration for work.
Please spare me a little of your precious time. I am extremely grateful.
I just flashed the Vbios K5000M by @Klem, and @Pseudodeed.
Grateful for that

Sorry for my English.

You'll need an SPI Programmer to unlock the BIOS for overclocking the CPU. For the GPU, you need to flash a custom vBIOS in case you want to pass the limits.

Hola tengo el mismo problema no pasa de 135mhz y si lo modifico me da 324mhz me podrías ayudar

La mía no estoy tratando de subir quiero probar vbios para mi dell m6700 vi en un foro que lograron subir a mas de 800mhz el core gpu me gustaría probarla.

You can try to modify the vbios yourself with Kepler Bios Tweaker. I can't attach my orignal K3000m bios and the modded one, but I've been using it for years. It's not a great overclockeable card, though.

@KlemHi Klem, you helped me months ago with my M17X R4, thank you for that
I have a Dell Precision M6700 with a GTX 980M now, and sometimes my games freeze and crashes (especially Warframe, it crashes constantly after some minutes of gameplay). I've heard about problems with power limits in the vbios with dells and alienwares and this gpus, and that editing vbios solved that issues, do you think it can be my case?
I also would like to ask if it's possible to fully unlock the M6700 BIOS to overclock the cpu, ram and that kind of things. 
Thank you very much for your work

 

EDIT: saw it in some notebookreview forums before they close the site, and in this video comments 

 

Hi, I have the same setup. Have you tried the OC' vbios in the first post? I don't know if it works for a Dell laptop. Thank you.

I just want to add that I have tested two 980m in a Dell M6700 and, despite of being Samsung memory chips, both GPU-Z and Nvidia Inspector shows "Hynix". Not sure that if it's a software bug or the info isn't provided by the laptop BIOS.

Honeywell PTM7950 is the solution. After years of using paste and liquid metal, this is the perfect combination of both worlds.
