NVIDIA Maxwell VBIOS mods - 900m series overclocking versions

Recommended Posts

Disregard, my previous question about applying the settings.  It did not take before, but after rebooting, the settings stick when I hit apply now.

Hi @Klem and everyone!

 

I recently got an unlocked BIOS (full FD unlock) and I'm playing with some settings and OC. Now I'm trying to get rid of the 135mhz limit and power limit, and voltage limit on my 940MX, but i'm not getting anywhere... And I'm not quite sure if those limitation can be configured on the tweaker, or if requires a hex edit, also, there was 2 vbios that matches my current vbios version on my BIOS dump, so I don't know wich one to use.  So I would love an explanation on that, and some help on modding vBIOS, and how to properly put it back on BIOS file for flashing. Thanks!

 

*Edit*

 

The file oprom.bin is the one with the same version currently installed on my PC. I tried to mod the file with maxwell tweaker, than replaced the stock rom on BIOS file with the modified rom, flashed using FPTw, the flash was successful, but after restart non of my alteration on GPU clocks worked...

 

I'm uploading the 2 vBIOSes i got

Master KLEM,

 

I have a power throttling with my Quadro M4000m from DELL;  anytime I try a benchmark or demanding application, GPU-z shows me a PerfCap reason: PWR, and that limits core clocks under 848MHz or less.

 

Tried overclocking it a bit, and flashed 2 different vbios from a Notebookreview forums user, but becomes a little unstable. I have seen some other Members in this topic requesting an unlocked VBios, could I ask for your help to mod mine?

 

Thank You

 

 

EDIT: Tried to upload my vbios (M4000m.rom), but forum shows me an error

Hi Klem,

 

Sorry for bothering, I recently reinstalled my OS and accidently deleted the modded bios you sent me 2 years ago. I browsed into my PMs, but the file you uploaded in 2018 is not available anymore. Would you mind sending it to me again, please ? My card is a GTX 980m 4gb, in a AW15 rig from early 2015. Feel free to contact me if you need further details !

      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!

      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.
