Does the VBIOS for 870M work for the 870M in the Gigabyte P35W v2? I haven't seen anyone confirm it working.

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).

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.

Oh you undervolted it for me? I'll take a closer look at the temperatures in-game. Thanks for the help! How much did you lower it?

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.

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 VBIOS

I 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.

If you have the UEFI mode enabled, you may want to take the computer out of UEFI mode JUST to flash the vBIOS. Once the vBIOS is flashed, you can put the UEFI mode back on, and go back to your computing.

That's how I did mine. (See sig for laptop)

At boot, hit F2, go into BIOS, then find how to disable UEFI.

Nope, there was no option to change into legacy BIOS mode. There was a setting for boot type, and it has only one option: UEFI.

You have to disable UEFI booting when you flash the cards and then turn it back on.

I actually don't think I have an option to disable it... either that or I'm not looking hard enough. I'll try again.

Wait, so do we have to flash in a different way if we have UEFI?

My Toshiba Satellite had a glossy screen, and it was a pain to use when sunlight shone through my windows. Now I have a Gigabyte laptop with a matte screen, and I'm enjoying it very much. Can't really compare the two screens in terms of colors and performance, since their age and technology difference is obviously an influential factor.

I'm wondering if the VBIOS for GTX 870M will work on my Gigabyte laptop, since it says "Clevo, MSI and Dell".

I'm using MSI RivaTuner to limit my frame rate to 60 FPS, but does it actually reduce my GPU's workload? Does it actually make the GPU render less frames or is it just limiting how many frames are actually refreshed per second while ignoring the extra frames processed by the GPU?

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.

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.zip

Any help or advice would be appreciated.
