RedLionRisen Posted October 1, 2013 Share Posted October 1, 2013 Does anyone have a stock 750m ultrabay they'd be able to extract the BIOS from and send to me? Quote Link to comment Share on other sites More sharing options...

It was successful, but the OS still sees it as a 650m. It seems that either the name/device ID will need to be changed in the firmware, or possibly a modification of the nvidia driver .inf files to install as a 750m will be needed to get SLI to work in a 750m system. Even then, the BIOS may need to be unlocked and the whitelist removed if the firmware/hardware device ID isn't changed. Quote Link to comment Share on other sites More sharing options...
Kwaz Posted October 2, 2013 Share Posted October 2, 2013 I'd imagine that you'd need to change the name / Device ID. I don't think that changing it is necessary. From my understanding it's the same hardware, they just changed the clocks. Keep in mind that even though the hardware is the same, the manufacturing may have improved over time allowing for the higher clocks.

Keep in mind that even though the hardware is the same, the manufacturing may have improved over time allowing for the higher clocks.But if the system reads the card as a 650m, I doubt it'll allow for the SLI configuration in a 750m system. I know from others that putting a regular 650m into a 750m system without a modified BIOS to remove the whitelist will prevent the system from starting. OTOH, I haven't heard of anyone with a modified BIOS trying it, but I still doubt it'd work off the bat because SLI requires the cards to be "the same". The nvidia drivers read the device ID in the gpu's firmware to determine what card it is and the SLI compatibility. Quote Link to comment Share on other sites More sharing options...
