Hi guys first time posting here. I'm hoping for a little help. I have a m17xr4 quite a few years old now which has gone through a couple of GTX675m's now. So recently I purchased a GTX680m from ebay and after installing I am getting a blank screen, with no back lighting or signs of life.Fans/Lights run and I hear windows start fine, but I'm unable to switch to internal graphics after pressing the Fn F7. If I hit enter I hear an error menu so something pops a new window up. If i remove the GTX680m it displays fine with its internal hd4000 graphics. I have been speaking to the seller and found that the card is from the M17xr4 120hz wide FHD 3D. My model only has the 60hz screen but I didn't think this was a concern. With the card fitted the GTX680m warms up a little. I removed the Nvidia drivers before installation through the control panel. I have tried Blind flashing the vbios with a stock bios sent from the original owner and also one from techpowerup with no change. I used nvflash v5.14.1 Dos version, I get 1 chime when I press 'y' 20 seconds in and get another chime 20 seconds later so I feel it has flashed but cant be 100% certain as I cant see. Any help is greatly appreciated. Many thanks.

So here you have my egpu project. Notebook HP Pavilion DV7 6103EG Bios: HP Insyde F.1B moded by donovan6000 CPU: Intel Core i7-2630QM IGP: HD3000 DGP: ATI 6770M RAM: 8GB Storage: ADATA SSD S599 64GB OS: 64-bit Windows 10 eGPU gear EXP GDC Beast DEll DA-2 220W Palit GTX680 4GB - PCI-E 2 x16 @ x1 2.0 DIY Setup 1.3 Results 3dmark06=18319 3dmark11.GPU=8222 Heaven 2454 Firestrike 5357 Sorry, in the title I'm not sure about mpcie 1 or 2 and bandwidth. Unfortunately it isn't worked plug and play, however worked flawlessly without change anything or using Setup 1.3 about 3 times in gen2 mode. Finally I went for Setup 1.3 and made recommended PCI Compation and chainload still worked just random few times even to set gen1 and disabled dGPU. Then tried to use command to reset and init iport in Setup 1.3 and looks like it solved my problem. I'm not sure I need every command. It is just my common sense. Still it is working like a charm at the moment without any problem. My final and working Startup.bat call iport dGPU off call iport gen2 2 call vidwait 60 call vidinit -d %eGPU% call iport reset 2 call iport init 2 call pci :end call chainload mbr Just wondering are my results nice, and I can leave it like this, or go ahead and do some more modifications. Like tweak more in 1.3, change the PSU. Or if this is the max I can get with the 680 does it worth it to get a stronger VGA, or no point because of the limits of my chipset and CPU. My Windows Power Plan is set to High Performance. Thanks for reading.

Looking for a UEFI vbios for GTX 680 AMP! edition Model Number: ZT-60102-10P I have attached the version bios for this card in case someone can modify it in some way. GK104.rom
