780M Dell or Alienware vBIOS

[leeshjnn]

When I looked up vBIOS for 780M on Techpowerup VGA BIOS collection, I found two vBIOS files for 780M from Dell/Alienware. The difference is the Alienware branded vBIOS has slightly lower core clock than the Dell. I thought Dell and Alienware are the same so why the two vBIOS? And my 780M can run Witcher 3 using Alienware branded vBIOS with no error while I always got white screen using Dell vBIOS in every 15 or 30 minutes. Does anyone know the difference or why it behaves like that? Thank you for your help.

Here is the link to Techpowerup site: https://www.techpowerup.com/vgabios/index.php?architecture=NVIDIA&manufacturer=&model=GTX+780M&interface=&memType=&memSize=

The Alienware vBIOS is 80.04.71.00.00 with Core/Mem 719 / 1250.

The Dell vBIOS is 80.04.AF.00.03 with Core/Mem 771 / 1250.

I use M17x R4 with i7 3610QM, 12Gb RAM and Windows 7.
