Just got Sapphire 5850 and flashed to MSI BIOS,
after installing MSI Afterburner 1.5.1 I can't access Core Voltage slider, it is all greyed out. I've tried setting Core control in settings and even using that MSIAfterburner.cfg file to enable overclocking but no go...

Latest drivers 10.3, Windows 7 64-bit.

Any ideas folks?
