A lot improvement from 800 series

GTX770M green PCB will work 100% on your GT60-ONC. No require to flash vBios. I'm using one for a month.

Hello svl7, Could you change Subsystem ID GTX770M Clevo vbios to MSI vbios? Hardware ID Clevo vbios PCI\VEN_10DE&DEV_11E0&SUBSYS_10081462&REV_A1 PCI\VEN_10DE&DEV_11E0&SUBSYS_10081462 VGA Bios Collection: Clevo GTX 770M 3072 MB | techPowerUp Hardware ID MSI vbios PCI\VEN_10DE&DEV_11E0&SUBSYS_10E81462&REV_A1 PCI\VEN_10DE&DEV_11E0&SUBSYS_10E81462 https://www.dropbox.com/s/w2vzetjckqgqdoc/11E0-MSI.zip Here is Clevo_V4 vbios from Svet (En-MSI) with some weird I explain below. https://www.dropbox.com/s/2dn5ji9cli84gym/11E0V4.rar In nvflash before flashing, subsystem ID changed to 10E81462, but it showed hardware ID to 0000 in Windows . PCI\VEN_10DE&DEV_11E0&SUBSYS_00001462&REV_A1 PCI\VEN_10DE&DEV_11E0&SUBSYS_00001462 When flashing back to other vbios it shown 0000 too. flash MSI to V4 (normal) http://i1176.photobucket.com/albums/x334/kiba208/MSI_vbios.jpg flash V4 to MSI (00001462) http://i1176.photobucket.com/albums/x334/kiba208/MSIV4_to_MSI.jpg Thank you in advance.

I think you may get a problem with optimus systems. The different generation of GPU make HD4000 on IvyBridge confuse.

Did you overwrite INF file correctly? I notice the INF file will be nvwin.inf.txt. You must remove .txt extension. Unlocked bios is good way to make the machine can recognize 680m. You need to change booting EFI compatible to Legacy ROM in PCI-E section.

You can download driver and INF modded from this link v326.41 Windows 8 64bit | NVIDIA Mobile OEM - 32x Series GeForce Driver release - LaptopVideo2Go Forums Extract driver files into any folders then copy INF modded file to Display.Driver folder for overwrite INF file and setup.

Some update. My 770M (MSI VBIOS) installed 326.80 driver mod INF, Iris Intel graphics driver (latest) and set PCI-E boot with Legacy ROM (unlocked BIOS). It work better than previous one. Metro Last Light and Tomb Raider 2013 significant reduce stuttering but still have TDR Failure recovery. Hope WHQL driver work 100%, good job NVIDIA.

I wonder your system has optimus?

Here is from official website http://www.msi.com/product/nb/GT60-0NC.html#/?div=BIOS&nbos=non-win%208 I notice bios same with GT60 OND, ONE Don't know why they removed GT60 ONC link but I bookmark it before

I think you must modify original vbios by changing PCI vendor ID to MSI only.

Here is my vbios kiba208 GTX770M original vbios.zip and here is MSI GT60 2OC vbios that worked on me but stuttering (TDR error) MSI NVIDIA GTX770M original vbios.zip I notice both size and version are different.

Your vbios all same as mine even start up with 1024x768 resolution locked and Intel HD4000 not working but your card can run without problem... Here is an error during installation

Uninstall both HD4600 graphics and NVIDIA driver. After restart, then try install Intel graphics HD4600 driver first and restart again. If your Intel HD4600 working, no exclamation warning, continue install this 326.41 driver then restart v326.41 Windows 8 64bit | NVIDIA Mobile OEM - 32x Series GeForce Driver release - LaptopVideo2Go Forums

It's all modded INF failed during install. May be it require unlocked bios access UEFI to work? or new vbios? ---update--- I flash MSI GT60 2OC vbios (80.06.54.00.1) into it and saw hardware ID change to PCI\VEN_10DE&DEV_11E0&SUBSYS_10E81462&REV_A1. Then I tried install 326.41 with modded INF from Laptopvideo2go seem everything ok. After that, I enter GPU-Z or some application that using DirectX it show me TDR error message "Display driver stopped responding and has recovered". I googling and found this NVIDIA thread https://forums.geforce.com/default/topic/389688/geforce-drivers/nvidia-statement-on-tdr-errors-display-driver-nvlddmkm-stopped-/ I think it has small hardware different, vram or something, cause MSI vbios not compatible with my 770M Alienware (Eurocom) and show that TDR error. Any idea?
