7970M Unable to change VDDC in VBE7

Recommended Posts

Hi guys!

 

I have a big problem-> I need to undervolt my GPU (MSI [email protected]_BIOS).
I am using this vBIOS: https://www.techpowerup.com/vgabios/132831/dell-hd7970m-2048-120629

Stock VDDC on this GPU is 1.050V and when I changing this one to 0.975 in VBE7 it is ok-> I can save it and flash it. Computer succesfully restarts but when I check modded settings the VDDC is still on 1.050V

I checked if the VBE7 seriously saving the VDDC to vBIOS but it is ok. I have no idead what i need to UV this card (i know it's possible...)

Everything is changing (GPU, MEM MHz) but VDDC can't change.

 

Please help me ;-)

      I got a msi ge60 2pf Apache pro & its specs :
       
      Processor-i7 4710MQ
      Ram-16GB 
      VGA- GTX 860M 2GB Maxwell 
       
      Could anyone tell me the best overclock that I could use on this GPU?
      Please keep in mind that the voltage cannot be changed as this is a laptop
       
      Thank you

      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.)

      Hi,
       
      I've recently got my hands on an M17x R4 Alienware Laptop from 2013 which I love. I've replaced the screen, keyboard, RAM, and hard drive to make it into a fully modern laptop. However, I'm currently waiting on a replacement for the 680m GPU with a 980m from ebay. My question for you all is, do I need to do anything with the BIOS to make this 980m work? Is there a way to prevent the laptop from using Intel HD Graphics with Optimus? I think the Intel HD Graphics on this laptop are currently broken as I see static-looking dots flash on the screen. (See image below for example). My theory is that because Intel HD Graphics with Optimus is still in-use while in-game, the dots are being caused by it.
       
      Thanks for any help in advance.

      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
