Andrix85 Posted June 8, 2013 Share Posted June 8, 2013 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 Quote Link to comment Share on other sites More sharing options...
