NVIDIA Kepler VBIOS mods - Overclocking Editions, modified clocks, voltage tweaks

Recommended Posts

I was talking about the mod here, not yours. No idea what you use.

Yes, that mod will work fine. What is your stock vbios version?

strange thing is it doesn't crash the driver. it just wont go above 993. all benchmark tests run ok and don't crash.

does the 780m vbios overclock edition posted on page 2 work on any 780m. I have MSI GT70 dragon edition 2. Thanks.

have you tried to increase power and thermal limits ? are you using inspector or afterburner?

Reflashed it with vbios from this thread. Now goes over 993 ok. Not sure what was wrong with the other one.

I am using inspector.

I am using inspector.

So were you able to overvolt the card?

Hi, thanks for the suggestion. I went ahead and applied a larger voltage increase (+75mV), but GPU-z still shows 1.012v under load. I can see that the core and memory slider increases are being applied, but so far voltage seems to stay the same.

The modded bios is still great, though. I noticed that if I back down a lot on the memory (to just +100), I can get +150MHz stable on the core, which is something I couldn't do before.

Thanks for BIOS:) i try 33. Version and my 680m working stable at 1000/2500mhz with stock voltage :)

Try EVGA precision, word has it that inspector has issues on some systems with the newest drivers.

I never over volt before, so what is the safe increment to do it at? Thank

Actual voltage wont start changing until you go +150 or higher. I think inspector doesn't see that 1.012 is the stock max correctly.

You have a golden 680m. Most cards need ~1.025V for your clocks, and the memory is phenomenal too.

BeemerBoy88 - Thanks for the suggestion. I'll apply the higher +150mv and see if the voltage actually increases.

SVL7 - Thanks for suggesting EVGA PrecisionX. I'll try to use that for monitoring my GPU voltage instead of GPU-z.

I'll let everyone know the results after I get a chance to try this. I ordered my P150SM from Mythlogic, and they did a good job of applying the IC Diamond paste. Even with a fairly susbstantial +135MHz / +500MHz overclock, the GPU usually stays at 75-80C during heavy gaming (...but I also tend to use medium image quality settings with v-sync enabled, so as not to have my GPU constantly straining at 99% usage). And when I have the fans running at full blast (100%), the GPU actually gets down to around 70-75C during gaming, but then it's also quite loud. Given the thermal headroom, I'm hoping to overclock just a little more with the modded vbios.

Does anyone know if the turbo button on MSIs does any good? Does it enable anything that would help with performance?

@cl2500

Is there much point overclocking if you're gonna be running at medium quality settings with vsync on, because then the GPU is not really being pushed anyway? Although, overclocking is kind of fun in it's own right!

K I was able to increase my voltage with a +150mV or higher. Currently setting it at +162.5 MV and +160/150.

Yeah, I need to adjust that. Forgot to mention it here. Up until +125mV nothing will change at all, the voltage change starts at +137.5mV. So anyone who wants to add some volts needs to put the slider at least to that value.

To put it on other words, setting the slider to +137.5mV will result in +12.5mV additional -> 1.025V instead of the max stock of 1.012V .

Slv7,

I'm currently running at 1.05. Is that consider bad? I don't have any crashes running 3dmark11 and I play sleeping dog for an hour or so without any issues.

Yes, that's right - overclocking mainly for benchmarks, just trying to figure out the GPU's performance. I think a lot of folks here love to tweak, and they just want to be as familiar as they can be with their GPU. Yes - for most games I don't feel the need to overclock, but it's nice to have that option for the really demanding ones.

Hi All would like to say a big thank you to svl7 for all his hard work getting a 680m (dell) from my m17xr3 3d so can't wait to flash the bios and get it tweeked.

I would just like to check before i start flashing about the cross vender compatibility or should i just stick with dell bios.

Thanks and keep up the fantastic work

Hi svl7, you modified my vBIOS for me, to unlock the overclocking limits. Thanks for that again, everything still good with it, but I'm curious to explore how much overvolting will likely give me as an OC increase. Max temperatures are 63degC, with fans at 61% and occasionally flicking up to 75%. If I run the fans manually, at 100%, then temperatures are 53degC. How much more performance would you think I could expect to see by overvolting from the current 0.925v maximum to perhaps 1V? Do you think it would be wise to try less than 1V, is 1V too much? And finally, would you be OK to modify the vBIOS for me (and of course for other folks that might download it)?

I also attached the modded vBIOS (from you) that I'm currently using, just in case that helps you know for certain which one I'm talking about.

Hey svl7 , sry muss auf deutsch schreiben hoffe das ist ok. mein english ist nicht so gut -.-

habe ein kleines Problem: ich habe nen P150 HM in welches ich gerne eine 680M Gtx einbauen möchte. Oder eine 7970 Mobility. das Problem sind nicht die Karten. die selber laufen mit deinem Bios. das Problem ist das Bios des P150 HM selber -.-

es sperrt die karte (sowohl die nvidia wie auch die ati ) hättest du die möglichkeit mir nen Bios von einem P150 Hm zu kommen zu lassen wo die karten erkannt werden. bzw wo sie nicht gesperrt sind ?

aktuell Zeigt das Bios nur an : N/A und im geräte manager vom windwos kommt nur nicht erkanntes gerät -.-

die karte selber ( 680 M gtx ) läuft aber in einem anderem Gerät P150 EM / 170 EM oder so ohne probleme.

hättest du da vlt eine Idee ?

mfg Alex

p.s. gemoddete Treiber gehen auch nicht.

I just had a chance to test the voltage sliders with the modded vbios (Clevo P150SM / GTX 780M), and I found that +150mv actually served as my "0" point of reference. In other words, here is what I found: +162.5mV translated to 1.025V (+12.5mV), and +175mV translated to 1.037V (+25mV). At these voltages, I was able to overclock to (1000MHz / 6000MHz) and (1025MHz / 6000MHz), respectively - so I was pretty happy with those results. At the higher overclock, the 3DMark11 graphics score was ~9600 (!). SVL7 - thank you so much for releasing this vbios, it's really great to see what the 780M can do.

Revised 780m "OC edition" added. Adds undervolting capabilities, slider correction and some other enhancements, see here:

      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!

      NVIDIA 'Maxwell' VBIOS mods
       
       
      Here you find modified VBIOS versions for the mobile parts of the Nvidia 'Maxwell' series.
      The VBIOS versions in this post are tweaked for performance and versatility. You'll get almost complete control over the performance parameters of your GPU.
      List of available VBIOS mods:
       
      Nvidia GTX 970m - 'OC edition' rev0 - >> 6 GB Version << - modified by @johnksss & svl7 -> see attachments Nvidia GTX 980m - 'OC edition' rev0 - >> 8 GB Version << - modified by @johnksss & svl7 -> see attachments  
      Screenshot demonstrating the capabilities of the 970m versions:

      >> Read the instructions carefully before flashing! <<
      If anything is unclear after reading or if you have additional remarks, please post in the thread.
       
      Flashing:
       
      - Go to the device manager -> 'Display Adapters' -> chooser your GPU, right click on it and choose disable
      - Flash the VBIOS with mnvflash, a modified version of nvflash (see attachments). Here are detailed instructions for nvflash in case you aren't familiar with it.
      - After the flashing is done: Enable the GPU once again in the device manager.
      - Reboot
       
      Do NOT use driver 347.09, it's broken and useless and won't allow you to overclock, even with the stock firmware.
      Don't distribute the files hosted here outside of Tech|Inferno. Don't modify the files you download here.
