Installed 860M GK104 in M17x R2

Hello,

I got a supposedly almost new 860M from SUADE8880.
The card is Kepler based - GK104 flashed with a slv7 vBIOS by SUADE8880.
Installed it in M17x R2 - A10 BIOS (stock).
My display is a LG RGB LED LP171WU5 TL A4.

The card works so far well but I am having a few issues:
1. Getting lower than expected 3dmark scores by about 10%.
2. I can’t turn the display off. When the display is being turned off, the screen actually becomes completely white.

Do you happen to have an alternative vBIOS for this card? Keep in mind its GK104.
Or can you suggest any way I could fix this?

Thank you!

 

I think you are the first to use this card in this laptop, but it's great to see it working ! For the lower 3d mark score, have you look after power saving system, temp and things ? This laptop should be able to cool this gpu without any problem i think. And so i have never seen a custom vbios for this card, you should look at techinferno forum.

 

The laptop has no problem in cooling down the card so I have no idea why I get lower 3dmark scores.. Maybe it's a bandwidth bottleneck somewhere.
On the other hand, all my ports work great, which is one of the main reasons I got the card.
Currently I am extending my M17x R2 on 2 other external displays via DisplayPort and HDMI. HDMI sound is also working.

I eventually flashed a Nvidia stock vBIOS on my 860M. It hasn't changed anything in regard to the white screen, which I get even before post.

I also tried a bunch of drivers, downgrading the BIOS A08, upgrading to BIOS A10 unlocked.... Nothing.
I am still getting the white screen. I am thinking that maybe with the unlocked BIOS I could play with the LCD settings.

Here is what I have:
