genesi88 Posted April 7, 2016 Share Posted April 7, 2016 Hi, i'm starting a new topic because i abbandoned the idea to put an old GTX 260m card on my laptop, so i decided to buy a newer one a nvdia GTX 780m. Searching on google i read that might be plug and play and i only need to mod inf. files to actually install the drivers. Now i came here and i see problems with audio etc...Do you reccomend me to install the unlocked bios version? currenltly i have the a12 stock. Do you think that the my current heatsink ( 3 pipe ) that i was using along with my old 7970m can fit into the 780m? Quote Link to comment Share on other sites More sharing options...

genesi88 Posted April 9, 2016 Author Share Posted April 9, 2016 back from work, installed the 780m, went into the bios set PEG and integraded to disable. boot up installed the drivers through modify inf file and it went ok. now the pc won't boot up cause it beep once at the begininng and it stops. i removed cmos battery, reseat and this time when the default option was loaded, it starts...went into the bios it recnognize the nvdia card, set PEG only and igpu disable, but after boot it won't start again...

Zoldago Posted April 9, 2016 Share Posted April 9, 2016 Not sure if i tried with the A12 but i used optimus and it worked fine. So i had no need to enable PEG only. Have you tried this? Quote Link to comment Share on other sites More sharing options...
umbrellacorp Posted April 9, 2016 Share Posted April 9, 2016 (edited) same problem I am running the 780m atm on r4 on unlocked a11. disable internal graphics set to peg boot does not work. in the unlocked a11 I can't find the igp disable function to turn off sound. I've tried legacy uefi everything i can think of as well. might try a differn't bios that i can disable sound.

umbrellacorp Posted April 9, 2016 Share Posted April 9, 2016 It might be a vbios issue being the 660m works on A11 unlocked with my 60hz or 120hz 3d screen but not with the 780m Quote Link to comment Share on other sites More sharing options...
Zoldago Posted April 9, 2016 Share Posted April 9, 2016 In the R4 i never used a unlocked Bios or made any Biossettings and had no Problems with the 780M (A12 stock legacy and A13 stock uefi mode, i think) nor wtih 980M (A13 stock full uefi only). I only had to use modded .inf. With Windows 10 i had to switch off the integrated by using Fn+F7 because optimus will not work in the correct way.

umbrellacorp Posted April 9, 2016 Share Posted April 9, 2016 I don't have the Dell drivers installed for the fn f7 but what about my 120hz screen. Would bypass it anyway. The 660m upon start up changed to peg automatically and worked. 780 screen lights up and does nothing. Quote Link to comment Share on other sites More sharing options...
Zoldago Posted April 9, 2016 Share Posted April 9, 2016 (edited) I only have a 60Hz screen so i dont really know how to do with a 120Hz screen. edit: maybe you have to do it this way https://www.techinferno.com/index.php?/forums/topic/7236-675m-to-880m-upgrade-m17x-r4-120hz-3d-screen/#comment-141241 Edited April 9, 2016 by Zoldago Quote Link to comment Share on other sites More sharing options...

Zoldago Posted April 9, 2016 Share Posted April 9, 2016 Did you read what i wrote in this thread on page 19/20 to ServusFidelis? That should work for 780M as well. Quote Link to comment Share on other sites More sharing options...
