NVIDIA Maxwell VBIOS mods - 900m series overclocking versions

Recommended Posts

You don't run it from the nvflash file. You should open an elevated command prompt then type in the commands. In my case: c:\nvflash\nvflash.exe -6 c:\nvflash\XXXXX.rom where XXXX is the vbios file name located in the nvflash folder.

PS: Don't forget to disable the display driver in the device manager before running the above command. ;)

Damn, thanks alot for the help!

Hi,

I have a P34W V3 from Gigabyte and the gpu throttle because of a limit of the TDP. Temps are good , less than 80°C ... the voltage decrease when full load in benchmark or some games.

Do you know if it's possible to have the same benefit of the bios in the first page of this topic for my laptop ?

Thanks :)

Hi,

The vbios is unlocking the +135MHz limit. But if you set into the vbios a +165 for example, will it work with last nvidia drivers?

Thanks :)

Is it still possible to OC with a modded vbios after the nvidia driver lockdown?

And to add to this:

1.) If one flashes the vBios: Will the recent drivers (347.52 for example) allow to adjust the clocks & voltage via NVinspector or MSI Afterburner?

2.) Or will all the OCing have to be done directly via vBios?

Best regads

P.S.: Can I use svl7s Bios mod on my MSI GT72 without harm or will I need a special vBios? - At best I`d like to recive an answer from the master himself ;-)

Can anybody please help me!? Whenever I try to flash with mnvflash it is telling me I/O Error: Cannot open file: 980MOC.rom.

I backed up my current vbios and was able to flash it, did this just to see if it worked. Whenever I try to flash the overclock vbios I get the I/O error message every time.post-33046-14494999444876_thumb.jpg

Please disregard my last post. I figured it out. Does anybody know of a maxwell bios tweaker version that will allow me to edit the 980m vbios? I tried version 1.36 and it doesn't work with this vbios. Thanks for any help!

I tried flashing the card with unlocked BIOS. This is how far I get, but it gets stuck at this point. The card is disabled in the device manager before the flashing. What could be wrong?

Hi svl7,

The OC vbios for the 980M is working well. Thanks a million!. It increased my Heaven Benchmark score by 100 points. But when I OC using afterburner, it crashes. I tried to increase the clock by 100Mz, it's not working.

During the benchmark, the temperature is 68°C, that's kinda cool :) I'm wondering if you can increase the OC a little bit.I have a GT72 with the GTX 980M (for information).

PS: I'm trying to understand how to tweak a vbios. There is many doc about BIOS tweaking but not vbios. I'm using IDA (and HEX editor) to disassemble the rom but it seems that I have to unpack it before, but I can't found any unpacker... if you can PM me some advice. I want to learn :)

Thanks.

Thank you so much slv7 and ohnksssfor all the hard work and effort you guys put in these vbios mods. A very big thank you to slv7 for all the work with earlier GPU vbios. I was using a modded version on 680m and it was great.

I was pretty scared to brick my card using windows version of nvflash as it looked like it was always just freezing. This looked wrong, since DOS version is almost instant in providing some kind of feedback after you type the command in.

I did the following to complete the flashing:

rebooted

enabled legacy in bios

booted to windows 8.1

saved backup vbios with gpu-z (had to wait for a few minutes, it looked like it was freezing at first, but just continue waiting)

disabled gtx 980m in device manager

ran cmd as admin and typed in the commands from OP. At this point it looked as if nothing is happening, but I kept waiting for at least 1-2 mins and finally saw some feedback. cmd showed my gpu and offered to continue loading new vbios. And the flashing was done!

rebooted and changed back into uefi, secure boot on, saved and booted into windows

I was quite scared that in windows something might go wrong, but it's just as easy as in DOS. So it will work, you just have to be very patient, which I wasn't at first.

First 3d mark 11 run with stock clocks (it was crashing with original vbios):

NVIDIA GeForce GTX 980M video card benchmark result - Intel Core i7-3740QM Processor,Alienware M17xR4

Nice GPU score, I'd like a score like that - double my GPU score and you've not even pushed the 980M yet! A travesty that NVidia have blocked overclocking of these brilliant 900M chips with their latest drivers!

Can anyone tell me the difference between Prema's BIOS and this one? My 980Ms are hitting high 80s (BIOS has hard lock at 87C so I'm not worried about that) and I am wondering if it's the vbios. I was getting 70s before. I have a P377SM-A and I see people posting issues with this machine and this BIOS so I'm unsure what to think.

not working ? ? ? and what is not working ? you cant flash ? and what the program says tell us ?

ok lets start this thing from the beginning...

first create a new folder in your C: drive and named it NVFLSH

if you want to use svl7's vbios then copy Nvidia 980m - 'OC edition' rev0.rom file into that new folder and rename it 980mslv7.rom

then copy all the files in mnvflash_windows_5.196.zip into the same folder again

then push and hold windows key on your keyboard and push X together and select command prompt (Admin)

then write there "cd c:/NVFLSH" enter

after this it should be like this C:\NVFLASH>

now write there "mnvflash -a" enter or "mnvflash --list" enter ..

now you should see there two cards as below;

<0>Geforce GTX 980m ......

<1>Geforce GTX 980m.......

and then the line you must write there to flash your cards is for the second card first

nvflash -i 1 -6 980mslv7.rom enter

and follow the instructions and press "y" yes all the time if everything is ok

after card 2 is finished then

you can go for the first card then

nvflash -i 0 -6 980mslv7.rom

and same thing above...and restar the pc and enable gtx 980m in device manager or install your nvidia driver

NOTE: Do not install 344.75 above drivers 347.09 and 347.25 both of garbage from nvidia for gtx 9xx users...

2nd NOTE:if mnvflash doesnt work use nvflash comes with premamod here is the link ==> http://forum.techinferno.com/attachments/clevo/13527d1420546022-clevo_8gb_gtx980m_oc_pm_v1.rar

3rd NOTE:if nothing works open windows control panel and choose region and in format section choose English (United States) and apply and restart your pc

then check the program if its gonna work or not...?

and Nooo its time to :53_002: or :Banane36:or :64:or :Banane45:or :waaaht:or :22_002:or :50_002:or :ah:or :23_002:or :too_sad: or :72: which makes you :45: or:59: or :doubt: or :02: and finally :34_002:

good luck dude i hope its gonna work this time

IMPORTANT NOTE : BEFORE FLASHING DO NOT FORGET TO BACKUP YOUR VBIOS FIRST...!

here is the command ==> mnvflash -b org980m.rom or nvflash -b org980m.rom

I have a gtx 980m installed in my computer, but my computer is reading it as a gtx 970m

so is there mcuh difference after manually appliying thermal paste ? and which kind of thr.pst did u use ? ceramic ,silk etc..

It's borderline... With the new paste job the temps are about 3-4 degree lower which is just enough so it doesn't start to throttle :-)

I' using either arctic silver or notua nt-h1.

Noctua pumps out fast which will drive temps up. It's one of the worst pastes to use in low pressure mounts like a laptop. Personally I've had the best results with Gelid GC Extreme and IC Diamond (I won't use IC Diamond anymore, it scratched my CPU so bad I thought the die had cracked) with GC Extreme performing better on the GPUs by about 2-3C than IC Diamond which already outperforms AS5 by a few degrees.

Grab GPU-Z and do it from Windows. When you look to the right of the BIOS version, there's an icon that looks like a chip. Click that and it will save your vbios.

As for nvflash, read directions. You have to flash in Windows and there are specific instructions including a modded Windows nvflash.

      i want to ask two favours and a question from this community ..
       
      1.) Can someone mod my 940 mx to increase the target temperature and allow higher overclocking than 135hzband voltage control
       
      2.) Allowing my i5 7200U to be undervolted to reduce overall heat 
       
      The question : I repasted my gpu and cpu cleaned it thoroughly, made sure twice everything is connected properly, use a cooling pad and yet the upper portion of my chasis above f1-f12 keys is so hot that i can roast peanuts on it. 
       
      (if i left out any info or missed something please reply i would really love to have a page that has everything for people who have this laptop specifically for light gaming.)

      3dMark11 Performance Preset Benchmark: http://www.3dmark.com/3dm11/11262792
       
      Required items:
      1.) Lenovo u310 (I have a Core i3 - Ivy Bridge, 8GB RAM)
      2.) 65CN99WW unwhitelisted.
      3.) eGPU (I used a EVGA GTX 750 Ti from another computer I had).
      4.) EXP GDC mPCIe Edition adapter (got from eBay - banggood seller).
      5.) ATX power supply (I used a 600W PSU from another computer I had).
      6.) USB wireless.
      7.) External monitor, keyboard, and mouse.
       
      Steps:
      1.) Obtain and install a unwhitelisted BIOS. If you are unable to obtain a unwhitelist BIOS, I think it might be possible to bypass it with Tech Inferno Fan's Setup 1.x (may need confirmation as I haven't used it myself yet.)
      2.) Shutdown computer and remove all USB devices, ethernet cables, power cables, card reader cards.
      3.) Remove mPCIe wireless card and detach antennas.
       
       
      4.) Attach EXP GDC external mPCIe cable to the former wireless slot and screw down.
       
       
      5.) Attach HDMI end of the mPCIe cable adapter to the EXP GDC device.
       
       
      6.) Attach graphics card to the EXP GDC device (I moved my laptop off the desk and onto the side shelf to make room on the desk for the monitor/keyboard/mouse).
       
       
      7.) Using the power cable adapters that came with the EXP GDC device, I hooked in my ATX power supply's 20 pin and CPU 4 pin cables. Then hooked the other end (8 pin) into the EXP GDC device. My EVGA 750 Ti also required that I use an additional PCIe power cable (6 pin) in the top of the card.
       
       
       
       
       
      8.) Then I attached my misc devices (HDMI monitor, USB keyboard/mouse/wireless adapter), and hooked in my PSU and powered it on (below is image of final product, also moved HDMI cable out of the way).
       

       
      9.) Power on your computer and let it install the standard VGA drivers and then install your drivers (I didn't have to go in the BIOS for any graphics settings, which it doesn't have anyways, nor did I have to disable iGPU in Device Manager before the card was added).
       
      Extra Info:
      I found that most games will play on med settings with about 45 FPS with this particular card.
      BDO: Upscale on - Anti Aliasing on - SSAO off - med settings.
      Skyrim: Med-High settings.
      Fallout 4: Med settings.

      ok, so, i have a serious problem atm.
      im trying to mod my bios so that i can go past the normal overclocking limit. however, everytime i try to do it, it always says "file size does not match existing bios size!", and it's really annoying, since i had to find everything myself, as no one else online tried this on my specific model, besides me. (which surprises me, really)
      this is the guide im following:
      So this is my detailed description how I managed to mod and overclock my GTX 960M in my Lenovo Y50-70. Please note: it is very dangerous to play with the BIOS, so you need to be very careful! I take NO RESPONSIBILITY for any damage or misuse of the information below! Use it AT YOUR OWN RISK!
       
      -------
       

      Necessary tools:
      A. Fptw64 from Intel (9.5 or above)
      http://forum.hwbot.org/showthread.php?t=75024
      B. PhoenixTool (2.50 or above)
      C. Maxwell II BIOS Tweaker (1.36)
      https://www.techpowerup.com/downloads/2562/maxwell-ii-bios-tweaker-v1-36/
       
      -------------------------
       
      How to flash Modded BIOS:
      0. Flash the latest (3.03 now) official BIOS
      1. From Windows, start 'cmd' as Administrator and read your your BIOS via Fptw64:
         Fptw64 -d BIOS.ROM -bios
      2. Reboot, enter your BIOS and check "Enable downgrading BIOS" feature (we need to downgrade first in order to flash the modded BIOS)
      3. From Windows, downgrade to 1.13 (this is necessary because the newer BIOSes have protection against mod-ding)
      4. After reboot & reflash, start Windows, then enter standby, wait a bit, then wake up the machine
      5. Create your modded BIOS, see separate list below
      6. Start 'cmd' as Administrator and write your _modded_ BIOS via Fptw64:
         Fptw64 -f BIOS_MODDED.ROM -bios
       
      -------------------------
       
      How to create modded BIOS (point 5 above):
      5.1 Start PhoenixTool.exe from Phoenix Tool 2.50 and open your previously saved original BIOS.ROM from point #1 above
       .2 The tool analyses it and shows some messages, click OK
       .3 Now you can find your vBIOS in the "DUMP" subfolder in the folder containing your BIOS.ROM, with the file name:
          BE13645B-2C2C-44D2-A64F-0EA052C34597_1796.ROM
       .4 Create your modded vBIOS, see separate list below -> let's call it 960M_OC.MOD
       .5 Click on "Structure"
       .6 Open "EFI BIOS" tag
       .7 Open second "File Volume {7A9354D9-...}" tag
       .8 DXE Core -> Compressed Section -> Raw section -> File Volume {7A9354D9-...}
       .9 In the very long list, find the following tag (usually displayed at around 80% of the list):
          Freeform {BE13645B-2C2C-44D2-A64F-0EA052C34597}
          This is the item containing the latest vBIOS
       .10 Open the tag, then "GUID defined section", then click on Raw section. "Internal number" (in the top right corner) should be 1796 for BIOS 3.03.
       .11 Click on "Replace" and select your modded vBIOS (called 960M_OC.MOD above)
       .12 Click exit "Exit" and say Yes to "Save changes?"
       .13 Close the Phoenix Tool; now you should have your BIOS.ROM updated (the original will be saved as BIOS.ROM.OLD for safety)
       
      -------------------------
       
      How to create modded vBIOS (point 5.4 above):
      Use Maxwell II BIOS Tweaker to change BE13645B-2C2C-44D2-A64F-0EA052C34597_1796.ROM;
      5.4.1 Open the ROM
         .2 Change "Boost Clock" on "Common" tab to the new boost-ed maximum value
         .3 On "Boost table" tab, use the slider in the right bottom corner to increase your max boost-ed value to the same number
         .4 On "Boost states" tab, at P00 profile, change the MAX values in the GPC, L2C and XBAR fields to the same max boost-ed value
         .5 Save your modified BIOS and rename it to 960M_OC.MOD
       
      (My boost-ed max value was 1359 MHz. I could then use MSI Afterburner's software tuning -> my 960M could reach 1454 MHz without voltage increase.)
      i know that it's for a different laptop, but its basically the same
      ill provide more info when im home

      Who can help me with modding and getting my 980M working?
      I replaced the M6100 that was originally in the laptop with a 980M but I can't seem to get it to work. I keep getting Code 43
      the Hardware ID : PCI\VEN_10DE&DEV_13D7&SUBSYS_15CD1028
      I heard i need to modify and INF file but i have no experience with it
       
      The vBIOS is from MSI
