Volt Mod SAPPHIRE 5850

[Andrix85]

Hy boys...

 

I bought this SAPPHIRE 5850 but I can't change the voltage with SAPPHIRE TRIXX o MSI BURNER, when I click appply the voltage don't change. With MSI AB I can set 1.35V max.

 

Why ? This is the pcb. It's reference or not ?

 

Thanks

Ok, but why if I can set the voltage with AB, than doesn't change ?

it is reference with volterra VRM , pwm controller VT1165MF ...dont need hardmod , you can comand i2c bus adress from pwm with riva tuner and volterra plugin , try gpu tool

Thanks Nachty...I try AB 1.5 or Rivatuner..Perhaps it's Vista that has problems...

ATI Tray tools works with Volterra IC's as well for voltage set..

nachtfalke is right.

gputool is best(easiest) for volterra based gpu´s
