I finally got around to attempting an overclock on my 5850 again. I could get it stable around 890 but it would artifact at 900, at 1.15V. When I upped the volts to 1.3V and nothing changed, I decided to take a look at the voltages.
Low and behold, GPU-z and MSI AB were both indicating a maximum draw of 1.088.
Now I'm stuck. With the unofficial edit in MSI I can still push the core higher. My problem is that it's not putting into effect any volt mods I apply.
I've looked around in other threads but they all seem to be with having an unlocked MSI AB, or pointing to non-reference 5850s ... neither of which applies to me.
Any ideas how to get extra volts into my 5850 ?
