dennis96411 Posted June 21, 2014 Share Posted June 21, 2014 I would love to be able to lower the voltage of this guy to lower its heat. I realize that there are a few modded VBIOSes for the GTX 870M, but since Gigabyte is sort of fresh in the notebook industry, there may be some differences in their variant of the card.Here is the VBIOS: GK104.zipAny help or advice would be appreciated.

dennis96411 Posted June 23, 2014 Author Share Posted June 23, 2014 Hi. This is for you.Thank you, kind sir. I will try it out and report back.EDIT: Never mind, I need to have 5 posts. I'll come back to this later.Sent from my SAMSUNG-SGH-T989 Quote Link to comment Share on other sites More sharing options...
dennis96411 Posted July 2, 2014 Author Share Posted July 2, 2014 Okay, so I'm preparing to flash this tomorrow, and I would like some tips first beforehand.I have done the following:* Changed my BIOS from UEFI to legacy mode* Prepared a bootable flash drive with all the necessary files and the VBIOSI would appreciate it if someone could clear these up for me:* If something goes wrong during flashing, would I still have a video feed? My CPU (Intel Core i7-4710HQ) has an integrated graphics chip (Intel HD Graphics 4600) in it, so I'm guessing it'll use that.* I'm only going to undervolt my GPU; not really worried about overclocking. Is there anything to worry about? What would happen if I undervolt it too much?UPDATE: I went ahead and flashed the VBIOS provided by Klem without a problem. I can now see a few things in GPU-Z that were previously not present, such as temperature and voltage. Now it's just a matter of changing the voltage.

dennis96411 Posted July 5, 2014 Author Share Posted July 5, 2014 Hi. This is for you.Wait, what does your VBIOS do? I can't seem to change the voltage; it seems to be the same as before. Quote Link to comment Share on other sites More sharing options...
Bios Modder Klem Posted July 5, 2014 Bios Modder Share Posted July 5, 2014 You ask lowered voltage for GPU core. I just do it. Flash your original stock vbios, run GPU-Z monitoring window and run 3D Load. Look at your voltage. And then flash mod vbios and run GPU-Z monitoring window and run 3D Load. Look at your voltage again. Quote Link to comment Share on other sites More sharing options...

I'll take a closer look at the temperatures in-game. Thanks for the help! How much did you lower it? Quote Link to comment Share on other sites More sharing options...
dennis96411 Posted July 31, 2014 Author Share Posted July 31, 2014 Is there a way to undervolt it more? I don't notice any significant difference in temperatures under load compared to stock with just -18 mV (what NVIDIA Inspector told me).

zolom Posted August 22, 2014 Share Posted August 22, 2014 Hello,I happen to have this laptop. Does this modded bios allow voltage control ? Or is it simply undervolted ? Quote Link to comment Share on other sites More sharing options...
durchstanzen Posted August 25, 2014 Share Posted August 25, 2014 Hi.I experimented a litlle with the keplerbiostweaker and was only able to get a lower voltage offset. A Voltage Unlock would be great. I´m using a GS70 with the 870m and am trying to get the heat problem done. Good alternative without bios tweaking is to set a lower temprature cutoff via MSI Afterburner for example.Greets, d. Quote Link to comment Share on other sites More sharing options...
