Lenovo Y500 SLI and Win 8.1

Right ever since Win 8.1 the Vbios voltage rom Jester made has not worked since flashing Lenovo vbios update to get the Sli working for Win 8.1. I have since used the Kepler BIOS Tweaker v1.25 tool and modified the Sli 650M voltage to be 1.1 in P5 state for the new Lenovo vbios.

Hope this helps others.

Edit: I have now attached the ROM file from my SLI 650M card and the BAT files that I use to over clock both the onboard and SLI card as I have not modified my BIOS in conjunction with Nvidia Inspector.

The overclock enables the voltage to be V1.1 on the SLI ultrabay card only, underclock returns to stock.

PLEASE USE THE FILES AT YOUR OWN RISK AND WILL NOT BE RESPONSIBLE FOR ANY DAMAGE TO YOUR SLI CARD. YOU CAN AMEND THE BAT FILES TO LOWER THE CLOCKS ACCORDINGLY PRIOR TO ANY TESTING.
