Tulius Posted August 8, 2014 Share Posted August 8, 2014 I try to upgrade the old 5850M to a 7970M in my friend's M15X-R2 (i7-740QM)... it boots with no beeps but freezes with a white screen on windows... I really tried everything I could but to no use, only gives the same results. The card is using the sl7 7970M overdrive bios and I heard this model is incompatible with 7970M with 015.022 DELL bios, is it true? If its the case what can I do to fix this? Thanks in advance. Edit: Anyway I really dont know if its really the R2 or the first model of M15X and about the Vbios it was originally a 015.021 bios before flash.

Gibbynator Posted September 6, 2015 Share Posted September 6, 2015 It would be helpful to have more info on your specs. I would need your BIOS version (usually A##), Windows version, and you can find out model by booting into safe mode and checking system properties, or more simply by flipping it upside down and reading the model info from the service tag sticker. That being said, try this guide: http://forum.techinferno.com/alienware-m15x-aw-15/1731-%5Bguide%5D-m15x-amd-7970m.html Quote Link to comment Share on other sites More sharing options...
Genetics Posted December 15, 2015 Share Posted December 15, 2015 On Windows only? Same result even on safe mode? Quote Link to comment Share on other sites More sharing options...
