KFA2 GTX460 1GB vs. HD5830 1GB: The Showdown!

[Ket]

Have you tried Extreme Tuner HD from Galaxy?
You might want to give it a try and see if voltage options are available for this card under that piece of software.

EDIT.
Just realized that voltage controller is up6206. It does not support I2C. Does it have secondary voltage controller chip like some MSI cards did in the past to have voltage control on their 5830 cards?

There must be a secondary because if I use nVidia Inspector voltage can be adjusted up to 1.087v

Did I not tell you this long before you bought the 5830?

You should have bought a 5850 like I suggested...

However, the GTX460 is a nice card. ...

I didn't buy the 5830 to use, I've made that quite clear numerous times. I bought the 5830 to review it now its had the benefit of some more mature drivers for it and to test ATi claims of it going head to head with the GTX460 (which we all know is BS, this review just unquestionably settles it). End of the day the 5830 is a midrange card (hence the cheap price of £140) with a highend product nametag. The 5830 is more like a 5790 or 5810.
