I have the same question as Wesley55. I just recently got a Sapphire 5850 (http://www.newegg.com/Product/Produc...-884-_-Product
) for my new system, I'm pretty sure it's a non-referrence card. I was trying to overclock it yesterday with MSI Afterburn, but was only able to get stable core clock of 840Mhz, I was however able to push my memory clock up to 1140Mhz. I went into the settings to enable vcore adjustments, but it's still not allowing me to change it. I tired to use several other programs to see the voltage, gpu-z doesnt show it so I assume it's probably running at the default which I believe is 1.08v. The card runs at around 55c under load after the overclock, so I'm sure I have room to increase the voltage.
Do you know if I'll be able to flash this card to the ASUS BIOS, and if so, will I then be able to adjust the voltages. I know that's whats holding my overclock back, and I want to know if theres a way to get around this without having to voltmod my PCB.
