NVIDIA Maxwell VBIOS mods - 900m series overclocking versions

Recommended Posts

As guideline:

With the 970m mod you can expect about 10.1k GPU score in 3dM11 when running the modified vbios at stock, and about 13.5k for the 980m.

Right, I'll add 3gb and 4gb versions when I get the chance. Also an Asus version. Should be up during the next couple of days.

Gotcha, tnx! Also, you meant 3dmark13, right?)

Awesome! I can't wait to try this tonight. Should the nvidia drivers be removed or is it okay to have them installed, just disable the gpu in device manager when flashing?

you are the best! by the way.. are you sure it is 3dmark 11? because i already got the 1.3k graphic score from 3d mark 11 test... not even flashing bios yet.

may be you mean the Fire Strike?

No, I mean 3dMark11. There's no 3dMark13 anyways :P

Hehe) That's how some people call Fire Strike - 3dmark13!

I thought you were talking about overclocked results for the GPU, cause i saw Prema 970M run and he hit 10.1k GPU score in Fire strike!

Just disable the gpu or gpus in device manager. Start the flashing process. then re enable gpu or gpus. Then restart machine.

That was just a guideline for people to see whether the card is performing as it should. The vbios is not overclocked by default since every system and card can behave differently.

I've seen people posting benchmarks with a 980m having 10k GPU score in 3dM11 and wondering whether everything's okay - well, in that case it's not. That's why I put those numbers there, for people who aren't that familiar with how it should perform and don't know what they can expect.

With overclocking you can get 16k+ GPU score in 3dM11 with the 980m and 14k+ with the 970m.

I followed the procedure.

and did the following (under command prompt - admin)

-Disabled 970m under device manager

- command prompt with administrative priviledges

- Went to Mnvflash and input the following command:

ex: c:\mnvflash -6 bios.rom

and i get this error

"ERROR: FIrmware image filename must have a valid extension. (.rom .nvr. efr. ef)

I've got the vbios version Clevo 970M vbios version 84.04.22.00.13. used with MSI GT60-16F3

====

Update :

Got to flashed it.. the file name is too long so the solution is just to put the name like this . ex: c:\mnvflash -6 Nvidia~1.rom

then follow the procedure.

For 24/7 i'd recommend any highest overclock you can achieve with no voltage bump. For benching - there're no limits! Just make sure your temps are in safe range, not more than 85C.

So far this is the stable bench in 3dmark firestrike

post-7316-14494999032584_thumb.jpg

core clock = 175

mem clock = 600

Do you think getting an extreme mobile proc will help increase the benchmark? By how many pts you think? Thanks

Thank you to both of you for all of your hard work and dedication to this community. Where is the tip jar?

What exact does the power limit slider effect? I understand the voltage offsets, but not sure exactly what the power limit does and how its effected by the limit I impose. I assume 100% is stock.

The power slider will determine the maximum power that the GPU can draw in Watts. If you overclock then you'll want to increase the power slider beyond 100%, otherwise the GPU will throttle it's clocks when it hits the 100% limit. If I had such a GPU, and my temperatures were good, then I'd just put the power slider to max to avoid any power related throttling.

it seems that I've hit the limit for my 970m

175 = Core clock

600 = Mem clock

I wont touch the Power limit yet (default settings) unless you guys know the safe limits to move the slider for this one.

      I have recently upgraded my laptop(an M6800 firepro 6100) and replaced it with an GTX 980m. Nvidia says that the latest driver(461) supports my card but i can only install up to 388.13 Ive tried to mod it but i can't figure it out. I can run the latest linux driver tho

      I have spent a little time in the past few days looking around this site. I would love for someone to point me in the right direction to a forum that has information that could help me out with my problem.
       
      I have a:
       
      Alienware M17XR3 
      Windows 7 Home Premium 64-bit
      Intel I7-2820QM 2.3
      Bios InsydeH20 Version 1.0 A12
      NVIDIA GeForce GTX 460M
      (4x) 4 GB Ram
      samsung 2.5" 256 SSD (SATA3.0Gbps)
       
      It has been an amazing machine for the last 10+ years. Minor issues, nothing that an Alien Respawn could not fix, till now! On battery power it works just perfect.  Then I plug it in and it's all OK until I try to do anything, and then the screen goes white. The screen sometimes goes yellow, sometimes blue, but mostly white screen. It will do nothing until I do a hard reset (holding the power button till it turns off and turn it back on) with the power unplugged.  If the power is not unplugged then it will go through boot up to windows swirling dots then go white again. If I plug it in and do nothing I can charge it, unplug and continue what i was doing. I have tried a lot of solutions bouncing around the internet, and thought I was having a DC Jack connection issue (replaced the ac/dc power adapter, then the motherboard). I get a better connection now but with the same white screen result. I stumbled into this forum and I'm hoping to find solutions to my issues.  Then upgrade like so many others have.
       
      Any ideas, comments or suggestions welcome.
       
      Thank you in advance!

      Hello,
      does anyone know, which is the chip holding the VBIOS-ROM on an AMD Pro-WX 7100?
       
      I've two AMD Pro WX 7100 which doesn't work. One has maybe a wrong VBIOS and gets deativated in BIOS before any system boots. The other one is not recognized by the MB so I suspect this one to be defective and un-soldered two chips, which I suspect to be the VBIOS-ROM:
       

       
      On earlier GPUs, the VBIOS was the chip closer to the GPU. But here, this chip has a bottom SMD contact which looks more like some power electronics...
      So before I start soldering on the probably working GPU - can you tell me, which actually is the VBIOS?

      Thanks.

      Hello everyone! I am looking for an answer to a problem I cannot find a solution to ... I purchased an Amd wx 4150 MXM GPU module su e bay to upgrade my HP 8570W Mobile Workstation which is currently equipped with a Fire Pro M4000. Once the new GPU has been installed, the PC screen no longer turns on but works only with external monitors connected via the docking station. The same happens once the drivers are updated! If I put the old card back on, the integrated monitor starts working again ... How can I fix it?

      Bios Release Version – v2.0.0
       

       
      Updated or Modded Items:
      A11 UNLOCKED BIOS FOR m18Xr2 (UNLOCKED BY SVL7 AND FULL CREDIT GOES TO HIM FOR UNLOCKING!)
      SVL7 Also created the PRR2.EXE tool that allows you to flash the new bios by unlocking it.  (FULL CREDIT GOES TO HIM FOR THAT FILE PRR2.EXE)
       
      Here are ALL the things I've added, modded, and enhanced on this bios -
      I've added FULL LEGACY SUPPORT ON THIS BIOS with ONE or TWO CARDS (SLI).  You can FINALLY use Win 7 OS on your machine and run the 900 series GPU's! 
      This is a MAJOR breakthrough!
       
      LEGACY SUPPORT Confirmed.  Works with 900 series GPu's in single OR SLI formation Updated the Intel RST Legacy to v12.9.0.2006 (Supports TRIM in RAID0 - CONFIRMED) Updated Intel RST UEFI to v12.9.0.2006 (Supports TRIM in RAID0 - CONFIRMED) Updated the ONBOARD Video Card for the HD3xxx to v2171 - FROM v2132 Updated ONBOARD Video Card for the HD4xxx to v2171 - FROM v2132 Updated the LAN Firmware & PXE Boot from 2.0.5.9 to v2.0.6.6 ADDED NvMe Support for m18xr2 ADDED M.2 support for m18xr2 Updated CPU Microcode to v29 for the 2900 CPU's Updated CPU Microcode to v1c for the 3900 CPU's Updated GOP Driver for Intel Sandy Bridge CPU Updated GOP Driver for Intel Ivy Bridge CPU Updated MAIN GOP Policy module for the m18xR2 Eliminated some code that wasn't used in the m18xR2 Updated CSM Module (v2) Streamline some coding to make mod(s) run a little more efficiently (v2) Added FPARTS.TXT to rar file in v2. (I had forgot to add it in v1) v2.5 to be released shortly.  I've updated a few more modules that I didn't realize could be updated.  (It's only 3 modules, but it's still an update!)   It should be released in about a week.  Hope this helps ya'll!  
      Instructions to flash:
      Use a flash drive to create a boot disk into dos Unzip ALL files into the root of the flash drive (flash.bat, r2final.bin, fpt.exe, flash.bat, prr2.exe, fparts.txt,m18r2.hdr, m18r2.hdr.bin, readmefirst.txt) BOOT INTO DOS – Note, that when you set the bios to legacy in order to boot into dos, you MAY have to reinstall OS!  (Just be prepared to reinstall no matter what) Once you boot into dos, run the file flash.bat It will unlock your bios (THANKS TO SVL7’s BIOS UNLOCKING TOOL – ALL CREDIT TO HIM FOR THIS TOOL!) Let it flash… Reboot your pc, and enjoy the MASSIVE updates!  
      Be on the lookout as I do plan to release newer version with more updates in the future.  However, it wont be for at least a few weeks as I'm now working on legacy support for the m17xR4 and several other systems.  So please be patient!
       
      ENJOY!
