I finally FINALLY found out what is failing to work on my GTX780 Gaming!!!
The 1.212v voltage modifier isn't applied by the BIOS somehow so even though I can unlock voltage in MSI AB and it shows 1.212v, it only runs at 1.15v actual! That's why his load voltage on 1.300v is just 1.238-1.244v. It's not running 1.300v, it's running 1.238v!
That's also why the LLC mod probably isn't working properly and is making the card crash.
With LLC mod it goes to 1.294v, which is like almost 60mV more then what it's set to.
I checked the PCB alongside my GIgabyte reference PCB and my hunch was right.
The MSI Gaming DOES use different VRM's, chokes AND caps. The same number of phases in total leaving the middle one empty, but totally different design / parts. The only thing they have in common is the NCP4026 controller :
The MSI's VRM's also stay MUCH cooler then the reference ones. With the MSI forced to 1.212v (1.270v set in MSI AB) and the GIgabyte on 1.212v with LLC enabled the MSI can still be touched on the back of the PCB after 30 minutes of Heaven. The reference cards PCB above the VRM's is way too hot to touch.
So, i gotta ask you for example, skyn3t or Occam, could you have a little look at the MSI Gaming BIOS and mod one for me?
I'm going to try my luck myself as well with the original BIOS (from TPU's BIOS collection since it's newer) and KGB but I doubt it'll work as i can't ever get power target to work with KGB / KBE 1.25.
