First off, Hello.

I purchased a Sapphire 2900PRO 1GB and its great, couple of questions.

I'm running under Vista x64, usuing Rivatunner to overclock and monitor temperatures and voltage.

In 2D the card runs 1.00v and in 3D it runs 1.10v, I've seen others who state their cards run 1.15v in 3D, is this because I'm running 2x6pin PCIe plugs and will running 1x8pin and 1x6pin unlock the 1.15v? Or is this just my BIOS, I've tried another BIOS, ATI XT and same thing happens, will a different BIOS from maybe HIS work?

At 1.10v in 3D I'm at 840 core, stable . But if there is more in her I'd like to try.
