gtx 770 for alienware m17xr3

I need help, my laptop does not recognize the new graphic card that I just bought, the graphics card is a gtx 770m and I can not get the machine to work correctly, will anyone know what the reason is or why it does not work?


Or the correct way to install the card?

 

770M require disable on board audio in the BIOS or else card not work, then install driver, then re-enable audio in the BIOS, but sometime this doesn't even work, some 770M in compatible. GTX 680M is better, return 770M if possible

 

If I recall correctly, it also requires to disable "SG" via an unlocked BIOS, doesn't it?

 

I did not say disable SG, i said disable onboard audio. no bios mod needed for that, but always preferable to flash bios mod before making upgrades

 

Yeah I see what you said

But what I meant in general is: does it boot without having disabled the internal Graphics Device?
Wasn't it like this in the r3 when upgrading the graphics card?

 

Not quite a requirement, but it is highly recommended to extract maximum performance from the gpu.

 

Ok, had always thought this is an absolute requirement and had done it this way when a r3 was to upgrade.
