  1. Hi, I will start by thanking anyone who reads this long post in advance for even getting through it and additional thanks for anyone who tries to help. To start I have 2 laptops, P750DM3 15 inch - i7 7700K, GTX 1060 (G-Sync) 16GB RAM P775DM3-G 17 inch - FBA 1440 Modded CPU, GTX 1080 (Unknown if G-Sync) 32GB Ram Both with Dsanke P7XXDM3-G modded bios, ME disabled. Both display the '-G' in the bios. Both motherboards are identical (model numbers, serial etc) apart from the motherboard having two positions for the battery terminal. One closer in to fit the 15 inch shell and the other further out to fit the 17 inch shell. Preventing me from swapping them out for one another. So originally I had the 15 inch version with the modded CPU and the GTX 1060, never noticed G-Sync as an option. I was waiting for a motherboard to rebuild the 17 inch laptop. I bought a GTX 1080 for the 15 inch. Popped it in, it posted, but would not install. Not detected by Nvidia setup. Flashed another version of the vbios to the 1080, upgraded the bios to a later one from Dsanke and it worked. Never noticed G-Sync as an option. New motherboard came so I rebuilt the 17 inch. Put the modded CPU and the 1080 into it, all set. Put the 1060 and an i7 7700k in the 15 inch, now both laptops had the specs I stated at the beginning, same bios and all. No G-Sync on either. I wanted G-Sync on the 17 inch. Looked at my vbios and found it was a non G-sync vbios. Flashed the G-Sync version, the screen did not come on, but windows did boot up and I was able to remote into it and see that the driver was installed. I could not access the Nvidia Control panel as the screen was not detected and it would not outpout via DP or HDMI. Running theory at this point is the 1080 card is G-Sync vbios compatible but the screen or bios or something is not and assuming the orignal shipped vbios was G-sync and the 15 inch could not install it because the screen or bios or something in the 15 inch was not G-Sync compatible as the base label had it down as P750DM3 (no G) prefixing it being G-Sync compatible. For some reason for the 15 inch, because there was now an official CPU in it, I decided to try the offical un-modded bios with ME Enabled incase I wanted to sell it. Here is where you could say the plot thickens. After flashing the original un-modded bios on the 15 inch with the i7 7700k and the GTX 1060, windows booted and gave me a prompt in the bottom right hand corner stated that a G-Sync compatible device had been connected. After opening the Nvidia Control panel G-Sync was now available for the first time on the 15 inch. I hooked it up to my monitor, and my monitor is also G-Sync compatible and was available to use on it. So now I was thinking. Okay well the modded Dsanke bios breaks G-Sync? So I re-flashed the modded bios to see if it was indeed the bios that broke compatibiity for G-Sync. Nope, G-sync was still available with the Dsanke modded bios on the 15 inch. I then put the modded CPU in the system to see if it would break G-Sync and it did not. So the modded bios and modded CPU are okay with G-Sync. So I am at this point thinking that for whatever reason, flashing an original unmodded bios triggers something in the EC Firmware or somewhere else on the system to enable G-sync if available, once enabled or the G-Sync feature added it remains on there regardless of whatever bios gets installed over it. So result for the 15 inch G-Sync is available for the GTX 1060 (Obviously the G-Sync version of the vbios is on the 1060). So next I decided to re-flash the GTX 1080 with the G-Sync version of the vbios. This was so I could put it in the 15 inch that now had G-Sync enabled to see if it would prove to me that the 1080 was infact a G-Sync compatible card and something on the 17 inch was stopping it from working. So I put the 1080 with G-Sync in the 15 inch. It did not post / display on the screen but windows booted and could be remotted into, same as the 17 inch. Running theory at this point is that the 1080 is infact not a G-Sync card, or that it just for some reason is not compatible with the 15 inch. Next I decided to do the same process I did for the 15 inch to the 17 inch to get G-Sync enabled. I put the i7 7700k and the GTX 1060 (G-Sync) into the 17 inch and flashed the original bios to see if I would be greeted with the G-Sync enabled prompt. It posted, displayed, got to windows with alot of GPU related blue screens but did install the 1060, but no G-Sync. So I thought now that maybe the 17 inch screen itself was not G-Sync compatible even though checking the spec said it was. So I put the i7 7700k and the GTX 1060 back into the 15 inch, got G-Sync displayed again. Then connect the 17 inch screen to the 15 inch laptop to verifiy whether or not the 17 inch screen was G-Sync compatible. No G-sync. So now my theory is that the 1080 may not be G-Sync and the 17 inch screen is not G-Sync. Fine, makes sence. But next I decided to emulate the setup of the 15 inch on the 17 inch to make sure the motherboard in the 17 inch was exactly the same and not just a close version. So I once again put the i7 7700k and the GTX 1060 (G-Sync) in the 17 inch laptop and then connected the 15 inch screen that I know is G-Sync compatible. No G-Sync. So basically, both motherboards when running the i7 7700k with the 1060 (G-Sync) and connected to the 15 inch monitor have different outcomes. The motherboard for the 15 inch enables G-Sync with that setup and proccess but the motherboard for the 17 inch does not. I cannot work out why identical motherboards with the same bios same components have different outcomes. Thank you to anyone that has made it this far and even more thanks if anyone has any ideas. UPDATE I found this thread https://forums.tomshardware.com/threads/can-gpu-vbios-be-flashed-to-support-g-sync.3796049/ This thread explains a person trying the flash G-Sync to a card he is unsure if it is or not. He had success. I used the vbios he used and now the 1080 (with G-Sync) posted in the 15 inch laptop. But it would not detect the card for install. Tried all different bios versions, un-modded, modded etc. Nothing. I then put the now G-Sync 1080 in the 17 inch (again same bios as the 15) and it detected and installed properly. But no G-Sync. I still cannot 100% verify if the 1080 is G-Sync compatible or not or if it can just take a G-Sync vbios but not use the feature. I also have another 17 inch eDP display that I connected to the 17 inch (auo b173han03.1) that has G-Sync as a spec, no G-Sync. Something about the 17 inch board will not take G-Sync and something about the 15 inch board won't take this (possible) G-Sync card.
  2. Hi there. I am running a GTX 970m 6gb with a cusotm cooler. So I wanted to try and see what I could do with it, but I am restricted to Afterburners +135mhz and no voltage control. Does anyone know how to unlock the vBios to have voltage control and more movement with the clocks? I have searched for a while and the power tables in Maxwell Tweaker II seem to make sense but not enough for my to try. If anyone could help that would be great. I've linked my vBios too if anyone does want to take a look. Thanks GTX 970m 6GB vBios
  3. Okay thanks i do also have a problem, having some bios trouble in that i dont know what mine is. In the bios it says its E1761IMS VER:000. In windows its E1761IMS VER:0.38 and i dont know what the correct update will be.
  4. Hey I have an Ms-1761 with a bios of E1761IMS ver0.00 i am looking for an unlocked bios upgrade the download links aren't working for me.
