GTX 675M vbios

Recommended Posts

Hy everone! :)

Is there a unlocked vbios for the GTX 675M for under-, overvolting? Or is there a Programm for Nvidia vbios Editing? I Have only found One for AMD Chips and the newer Kepler Chips but none for Fermi.

I`m using a Clevo P150EM if that is important.

Thanks

I have a problem with the 0.92V vbios

It start to Artifact with 740 MHz and the Nvidia Driver is always resetting. What can i do?

Maybe you reached your gpu overclock capability....

Beyond this, you may need an overvolted vbios to reach higher clocks...

I reach higher Clocks with lower Voltage. The stock Voltage is 0.87V and i reach up to 730 MHz and with the Overvolted Bios (0.92V) it start to artifact at 730 MHz.

Everyone please re-download, I just saw that the 675M has an additional power state compared to the 580M, not sure if it's used, but may work...

hi prema,

is it possible to undervolt the 580m in a p150hm?

Thanks in advance

I have added them here!

      Hi all,
       
      It has been a while since I did anything to my laptop (Clevo P670RG-G) and since I recently got a VR Headset I wish I could overclock my GPU a little. So far the NVidia software (on windows) doesn't allow me to overclock it (the linux sort of allows, which some custom Xorg options) so I decided to give a try modding the vbios.
       
      I read all sorts of issues / guides about it, and it seens that the hardware topology (where the vbios is stored and how things are connected) changes from machine to machine.
       
      What I know about my laptop is that it has two VBios, one for Hybrid Mode and one for Discrete Mode. I'm currently running the discrete mode.
       
      I dumped my VBios using GPU-z and opened up in Maxwell II Bios Tweaker. Everything seens fine so far.
       
      So I have few questions about it:
       
      - There is a way to just unlock the VBios to show the overclocking options in NVidia software? (That way I dont need to reflash to change clocks)
      - I can just flash this GPU-z dump to my VBios?
      - If I brick my GPU, that GPU-z dumped image is the raw SPI image, so if I managed to physically access the VBios, I can just reflash over it?
      - I saw some people saying that I might need as well to flash the main laptop bios as well, is that really needed?
       
      Thanks!

      After spending significant time and effort to obtain "DC" screen for 8770w (which is essentially a regular IPS panel with fancy board that converts 8bpc LVDS to 10bpc DP), I have finally got and installed one. All works great, except of the one problem...

      It has pretty bad banding / posterization in lower shadows. I have tried profiling it in different modes (full range, sRGB, rec709) - issue persists, and it indeed shows only in the lowest part of the characteristic curve. Mids and highlights are represented fine and show low deviation from reference values.

      GPU is HP K4000M, Nvidia drivers installed "as it is", video-card is identified without a hitch.
      Banding was not present with the original TN panel using the same GPU.
       
      While checking a software side, I have noticed that Win10 has bit depth set to 8-bit...
       

       
      My initial reaction was, - "Easy, let's change it in `nvidia-settings` and we're all set":

      ...but that would be too easy, right? After selecting 10bpc and clicking "Apply" screen went off and back on, only to show that depth stayed at 8bpc. Repeating the above few times yielded exactly the same result and I'm not in a hurry to meet a cliched (and laymen) definition of insanity.
       
      Let's check GPU-Z. So far so good, nothing unusual. Notice the highlighted BIOS version and subvendor string:
       
      Time to delve into other tabs. We are running WDDDM v2.4 which supports GPU dithering, but hey... BIOS version has changed!
       
      Briefly back to `nvidia-settings` to check what is reported by vendor's own utility:

       
      So far, we have two strings for BIOS version:
      80.04.5A.00.02 (let's call it an "A") 80.4.33.0.37 (let's call it a "B")  
      Notice how 2nd one seems to not follow hexademical notation. Lastly, "NVIDIA BIOS" drop-down, reports "A" version:
       
      ...and monitor section which confirms that rig is indeed capable of 10bpc, but currently running at mere 8bpc:

       
      Windows "Adapter settings", reports version "B". It's 2019, diversity is a must.

       
      "NVidia inspector" is of the same opinion:

       
      Now, let's use some seriously legit tools and check-in exported BIOS file in `nvflash`:

       
      Here we have two three interesting findings:
      Reported vendor is Dell, not an HP. See this link for details. BIOS version is back to "A". Have I already mentioned diversity? MXM module uses MX25L2005 flash storage in WSON-8 packaging. If things go real nasty, we should be able to rescue a patient via Pomona clip and external programmer.  
      Loading the same file in "Kepler BIOS tweaker" confirms the facts:

       
      EDID settings, courtesy of NVidia Control Panel. Hex dump can be found at the bottom of this post.
      ...Shall I be worried about "60.02Hz" refresh rate?
       
      To summarize:
      Why two different BIOS versions are reported? Anything to do with UEFI (e.g. HP is sideloading its own during boot)?.. Why two different vendors reported? As far as I remember, this is branded HP GPU. Where to get "clean" BIOS of K4000M for future experiments? Ideally from 8770w equipped with "DreamColor" panel from a factory.

      Hi guys, bit of a rookie to the whole EGPU scene. Currently I have:
       
      - MacBook Pro 2015 13inch (3.1GHz Core i7 16GB RAM)
      - Razer X Core 
      - Apple TB3 to TB2 Adapter
      -  TB2 Cable (Cable Matters)
      - 23inch AOC External Monitor
       
      I am wonder about what graphics card to get to run X-Plane11 with high graphic settings?
      I have purgewrangler set up and ready to use with an AMD graphics card, but am also open to the idea of an Nvidia graphics card.
      Any advice appreciated. I did not buy a Windows PC as I need a Mac for various other things and wanted an all-in-one laptop.

      There are several threads on requesting BIOS modifications here on T | I but I thought another one wouldn't hurt.
       
            Your request should look like:
      Brand Model Type of modification(For example: Unlocked, added support, Logo, microcode, ME firmware etc  
      I'll respond as soon as I have time as I'm also currently working on other projects(Requests by PM is also ok)
      If anyone else have the knowledge and time feel free to respond to requests
