NVIDIA Maxwell VBIOS mods - 900m series overclocking versions

Recommended Posts

Posted (edited)

Hi Klem,

can you please unlock my current BIOS ? I have a throttle on my gpu usage (about 475mhz max when used but 1126mhz in idle with the vbios Nvidia GTX 980m - 'OC edition' rev0   ).

 

With the original bios, I have more limited by memory  clock this time, 799mhz max and 1037mhz for the gpu clock

Hi!

Delete all overclock in Nvidia Inspector, put all settings to default, and create new screenshot with the vbios Nvidia GTX 980m - 'OC edition' rev0 (under 3D load)

It's weird it's indicated gpu clock max 541Mhz but when I don't use any 3D application, the clock bring me up to 1126Mhz

I think it's not a vbios problem, may be it's hardware problem. In any case try to search in Google and download DDU utility (Nvidia drivers uninstaller), run it and completely uninstall all Nvidia drivers. Also uninstall MSI Afterburner (if it installed in your laptop) with all settings. Then download and install Nvidia drivers with enabled option "Clean Install".

Sadly I always make this, it is possible that problem come from the nvdia driver ? What do you mean by hardware problem ? the card is broken ? I always problems with my cards, 880m with huge throttling before (never been fixed) and now this one, f*** nvidia.

I think that your laptop cannot provide enough power onto the MXM socket for a graphics card. This may be due to insufficient power from your Power supply, or insufficient power from the VRM's power converters on the motherboard.

Hi Klem,

 

im a new member and i need help on modified vbios of my Asus ROG GL2502VT GTX970m. im trying to upload the modified vbios but there is no luck. Error has been shown on below image and Original & Modified vBios was attached. im using MaxwellBiosTweaker_1.36 for vBios modification.

 

i hope you can help me how can i upload the modified vbios and if you can share some software for vbios editor.

Ummh I don't think so cause I already had this kind of problem with my old card (880m) but only with all nvidia driver after 327.23 (very old driver) now I just tested another driver just for check and as I can seen is that my gpu clock always throttle but not at 475 but 800mhz, of course I don't know where the real problem is but because I already tested several psu and because I current PSU is an 330W, I don't think that problem come from the VRM converter or this is the first time I heard that from this model of laptop, and in this case, how explain than differents drivers change the frequency of the GPU clock if I don't touch anything else ?

 

Also when I try to change the voltage or memory frequency with the vbios mod, it's doesn't change anything, it is normal ? Maybe you could check my stock bios and see i you can change something ?

This BIOS mod seem really great! At the moment my 970M constantly runs at 50 degrees and it has a lot more potential. Does anyone perhaps know if this vBIOS will work on the Clevo P751DM-G? Great work and thanks in advance!

That's great! Did you use the default BIOS when performing this vBIOS mod?

  I have a ASUS G750JY gaming laptop with the 980m 8gb and a very good cooling solution . I used to mod my own vbioses on desktop when I had my 780 , but now when I opened the vbios with MaxWellBiosTweak II I don't want to risk modifying and then flashig the vbios without being 100% sure. I see in Power that all the values are on 100 , so 100 W? On desktop the rule was to not set the PCI-E to more than 75 watts, those MXM cards maybe can pull more out of that connection, altough it looks exactly like a PCI-E connector. I have an ASIC quality of 74% and right now I'm on +135mhz on core, +600mhz on mem and benching/playing games with no problems while also staying under 80 C on the gpu. I would really like to see what more I can get out of this setup. I have a delta ADP-230EB T power brick, 230 Watts and when gaming full power I measured a 184 watt draw using a ampermeter ( 230V Voltage and it measured 0.8 Amps ) . I will attach my vbios so the nice guy I see in the latest pages can mod it for me. I honestly would've liked to download the modded 980m file and learn for myself what's modified there and modify my vbios on my own, but it just won't let me download it, my account doesn't have the privilege it seems.

      Hi there guys,
       
      I've been looking into getting a new GPU for my laptop (4-lane PCI-e) and enclosure (HP Omen Enclosure) but I cannot decided between the RX 5700 XT and the RTX 2070 (non SUPER).
       
      I did some price to performance calculations (higher is better) with some of the best prices I can currently get in the UK.
       

       
      The RX 5700 XT does perform better and is cheaper than the RTX 2070 (Although the 2070 does come with 2 games) but my main concern is drivers and from what I've heard NVIDIA cards work a lot better with eGPUs than AMD.
       
      If anyone has experience using both red & green or if anyone else has any other input i'd love to hear your experiences and input.
       
      Thanks.

      Hello everyone,
      some time by now I flashed a custom Vbios (thank you Klem) on an Acer Predator 15 G9-591 and I started doing some tests about how far I could go overclocking the gtx 970m without running too hot. With the voltage up to 1150mV and something like 300 additional MHz for the core clock, in the strongest stress condition for both Gpu and Cpu ( i7-6700hq undervolted), the Gpu reaches a max temp of 85C (with some 86 spikes but never more than that).
      Considering that soon I'm going to relid both Cpu and Gpu and clean everything in the internals (laptop is 4 years old) I think I'm going to have some additional heatroom.
      I've already tested some further overclocking and I noticed that even if the temperatures remains under 93C (which is just for testing purposes, but after relidding temps could be nicer) graphical glitches occur and after some time most games crash. But my question is, could it be because of lack of power supply? The laptop charger provides 180W 
      Could there be an increase in overclock margins with a 230W psu or something like that? (Obviously with the same 19.5V output)
      If anybody tried something like that on any laptop model, or knows the matter, I'd like to know

      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.

      I have been attempting to change my boost clocks values for the longest time, though I've been unsuccessful. I managed to flash my modded BIOS, though no changes seem to have had happened, along with no errors either. Here's all the stuff I used and was able to get. If someone is able to help me with this, it would be greatly appreciated.
