You could simply set an nvidia Inspector profile to load at boot.

I use a hex editor...

You sir, are a wonderful person ;)

The vBios mod installed without problems and the GPU is rock solid stable in my initial testing using overvolt at 1.1v and overclock at 1300Mhz GPU / 5700 Mhz MEM.

Temperatures are a little higher on 1.1v (6-10°C) during extreme gaming, but it was expected. Still they are in a safe zone in the 70's °C.

With 1.087v, the GPU OC's easily to 1300Mhz (1300+ boost) without extra heat and without artefacts.

So Overall I think the GPU does have a lot of room for improvement thanks to the good heatsink and fan on the sistem that keep up with the extra heat generated ;)

In the next weeks I will test the GPU on various overclock settings and post my results here for other G751JY owenrs.

Thank you again for taking the time to mod my vBios. Donation well deserved.

Should you need to test future updates of the same mod, please let me know :)

But more than synthetic scores, I am interested in a good stable gaming OC/OV that will last my 980m for a long time without killing it ;) and I prefer game benchmarks as they provide a real picture of the GPU's performance.

At the moment I have only COD:AW installed and I don't belive this game comes with a benchmark test. But, just for reference, on the penultimate single player map, "Captured", the FPS range go from 70-80 (STOCK) to 88-96 (on same OC/OV I made on Unigine Heaven 4.0 test)

BENCHMARK N.2 - Stalker: Call Of Pripyat

A rather old game, but still DX11. This are my benchmark settings:

Well I just used Prema's instructions (see rar file) and it all went smooth. The only precaution I used was to restart the computer before doing it.

As always with bios or vbios updates, be careful to have battery charged 100% and pc plugged in.

Good luck and post some fo your overvolting/overclocking solutions (possibly stable ones for gaming, not for benchamrking) ;)

You have the g-sync version of the GPU and need another mod.

Dump and PM me your vBIOS.

Hi Prema, nice to see you resolving it for the g-sync guys too :)

I have been using your mod (non g-sync) for a few weeks and it work perfectly. Great work!

I would like to have your personal opinion on one thing.

G-sync worked fine on my G751JY with the leaked drivers back in february 2015, and I belive the only difference between "g-Sync" and "non-G-sync" models is suposed to be a different hw ID for what are essentially the same hardware components...

Do you think is there any chance for us NON G-sync G751JY users to have a G-sync enabled somehow in the future? (with a Bios/vBios mod or some other way) ?:01:

Hi. I flashed the vbios with success for the 970M 3gb on my Asus G751 and I could bump up the core clock to 1400 stable but I can't seem to get the memory beyond +150MHz without random colors flashing in game. Tried lowering the core clock to a 1200 to keep the temp down but still not able to go higher on the memory clock. Any tips? I'm thinking that its my luck that I got a low quality memory that can't handle memory overclocking. But is it possible to increase the memory voltage like when we're overclocking system memory?

Another thing, will repasting the gpu improve my memory overclocking? I am due for cleaning out my fans and might consider doing a repaste job. Thanks.

Prema, is it possible to change the voltage to default, i.e. leave it untouched? Even though I repasted, the GPU gets a bit too hot for my liking with the new vBios so I'd just like to see how far I can go with standard voltage until I really need the additional performance. Also, I got weird behaviour: E.g. when minimizing Witcher 3 und bringing it back up again, fps was locked to 30 and the GPU wouldn't clock higher then ~670 until a reboot.

Also a question to everybody: Did you guys get voltage control working with Afterburner? I didn't, so I had to use Asus GPU Tweak, which is an abomination. I'd really like to stay with Afterburner...

Hi I also use Asus GPU Tweak. I am not 100% sure about this but I belive MSI afterburner does not support voltage control on our 980m...or at least I never been able to use it. Contine with GPU tweak, the latest version work fine for me :)

And about the temperatures...that probably depends on how fortunate you are with your GPU. Mine gets only sround 5°C higher with overclock to 1300 Mhz core / 5400 Mhz mem. And I sincerly don't know how much further I can go since I didn't try 'cause I don't need to right now. One thing I would control is if the metal plates fit well on the CPU/GPU since I find it strange that you have temp problems even after repasting.

Hi !

got g751jt 970m 3gb

right now I try prema mod I did also backup but I will need instruction in future how to do it .

Right now I use 1.1 v 300mhz core and 500mhz mem seeems to run very smoothly without problem

What a Beast

I thought so. There are people with really bad temps (me included) and there are people with awesome temps. I read the default voltage is kinda dependent on the ASIC score? Mine is beyond bad...

Before repasting I got nearly to 90°C under heavy gaming load, after repasting the 980m is significantly colder (~mid 70s under heavy load), same as the CPU now after repasting, though that are temps people got before repasting (GPU though, not CPU).

The heatsinks sit perfectly, they press uniformly and firmly onto the chips!

The default OC vBios voltage is significatly higher what GPU Tweak reports as default voltage now with standard vBios. Even with default vBios voltage and clocks, I cannot game for too long (for example demanding titles like Witcher 3 or Evil Within) before I get a "grey screen" and I need to reboot.

      Hello guys,
      I have a GT72VR 6RE with G-sync MSI Laptop. Sadly the GPU is partially dead (artefacts all over the screen, crashes, windows detecting a damaged hardware etc...).

      So I bought an other GTX1070 MXM on ebay, which was used in a Vortex G65 6RE before.
      Sadly, when I plug the new GPU in the laptop, the laptop screen stays completly off, but i can use the HDMI port. So i though that I would just have to flash the vbios to the one I was using on the GPU that died, but I couldn't because of a mismatch betwen the PCI Device ID.
      The new GPU ID is : 10DE 1BA1 - 1462 11AF and the previous GPU ID was :10DE 1BE1 - 1462 11AF
      Pretty close right? but the A1 and E1 variation are fcking everything up. I've read that 1BA1 is for non G-sync and 1BE1 is for G-sync. I've also read that the G-sync variation is not part of the card but is an external part no on the GPU board.

      So now I'm wondering what can I do : is there a way to force the vbios flash or to change the PCI ID ? I really need some help here. I'm no expert and I've try as much as I could. Maybe I need to do some vbios editing but I don't really know how to do it and what to do exactly to make this work.

      Thank you very much for your help guys

      Hi guys, I am the proud owner of a Clevo p775dm3-g notebook purchased from azom.systems (authorized Clevo reseller in India, Model rebranded as Azom Legion-17.3 inches). Here are my specs:

      Core i7 7700 (non-K version): undervolted by 110 mv and turbo boost disabled in BIOS- machine uses prema mod BIOS.
      GTX 1080: undervolted by 100 mv on all frequency steps using MSI afterburner voltage/frequency curve editor. clocks are untouched.
      16 GB DDR4: Cant remember clocks.
      1440p 120 Hz screen: No tinkering done to refresh rate.

      CPU has been delidded and repaste has been done on both CPU/GPU dies with gallium based TIM-Coolaboratory liquid ultra if I recall correctly.

      My issue is GPU hitting max temp limit of 90 degrees while playing DOOM and framerate drops from 110 avg to mid 60s-70s with horrible stuttering- this is thermal throttling for sure.

      System was running beautifully after repaste at 86 degrees max/ 77 degrees average at 100 percent fan speed. A month later I decided to see how much further I could push the system and ended up undervolting the CPU/GPU and RAM even further. The RAM undervolting part didnt work as well as I'd hoped, and I ended up resetting the BIOS to undo everything and reapply the previous setting (-110 for CPU with turbo boost disabled.) 

      I noticed that immediately after BIOS reset, both my CPU and GPU temps were 5-10 degrees higher even with the undervolt/underclock applied. Also, I think the fans were a bit louder before I reset the BIOS which leads me to believe that for some reason the fans are now capped at 80% max fan speed. There doesnt seem to be a fan speed selector in the BIOS or anywhere else so I cant say for sure whether this is a fan related issue or something else.Before the reset I could override the BIOS setting and set the fans to 100% by pressing fn+1, could I have done something to that setting after resetting the BIOS ? I dont think I have damaged the CPU or GPU as temps are holding fairly steady at 90-91 degrees and laptop doesn't shut down while gaming.

      If I have overlooked something or if anyone reading this has any solution help would be greatly appreciated.
      All settings/drivers/windows version/app version are exactly the same before and after BIOS reset.

      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.

      Hello,
       
      I am new on this forum, so I am sorry if posting at the wrong place. It's been 2 weeks that I am searching how to make my GTX 980M 8GB working Inside my Alienware 17 R1 (June 2014, i7 4710MQ, 60 Herts Display, OPTIMUS and the GTX 880M Inside died.)
      After "quickly" looking some forums, I saw that a 980M would easily fit Inside … but maybe I was wrong.
       
      Hardware wasn't a problem. I've also could install drivers by modding the nvdmi or nvcvi. inf files. The card was recognied BUT :
      the clock speed is locked a 135 or 405 Mherts and fan is not runing when booted up.
      I tried to flash vBios with nvflash and some ROM I found on vBios collection … but no way to get this working properly.
       
      So, i'm coming here. I've seen many people talking about Prema or svl7 or other big boss in the place … but ? how ? where ? when ?
       
      Inside the peripherial manager I have this in remote acces path : PCI\VEN_10DE&DEV_1617&SUBSYS_05AA1028&REV_A1\4&D590A51&0&0008
      So I assume my GTX 980M card ID is 1617 and vendor and PC Model are 05AA 1028.
      But near the "Standard Microsoft Video Card" there is a yellow exclamation point and Inside details it says "this peripherial doesn't work properly" when no Nvidia drivers installed.
      I could find some vBios with 1617 (Asus) but black screen at boot up. Since laptop model where not the same .. probably.
      And I wasn't able to find 1617 with the existing 05AA 1028 … as the GTX 980M was not an option for my model. (AW 17 R1 2014 ,60Herts)
      I tried 353.60, 382.33 and 419.35 drivers. The latest one seems easier to install but longer.
       
      BIOS is A16 from Dell. And I am using Windows 10. Got a Dell 330W brick. 
       
      I saw a guy with the exact model as me, he gets a modded vBios especially for his configuration, then everything worked easily … but can't find the topic again
       
      I guess depending on the card info and the laptop model … a dedicated vBios is required … 
       
      So, If anyone here got some informations or any kind of help for me, it would be very nice.
       
      Thanks for reading and help.  
       
      PS: there are a lot of files, pictures and links that I can't see on this forum .. even after registration ….
