Riva tuner help

[platinumike]

OK, in the latest version of rivatuner, and I remember this being there in the older versions. There are 2 places to overclock the same card, through "target adaptor" or "driver settings" on my older card(gf4 ti4200), I could raise the overclock on the driver settings and it would automatticly move it to where I oc'd it on the target adaptor overclock. My question is, now with my(bfg 6800 gt) new video card, The option to overclock through target adaptor is grey'ed out and I cant click the box, but I can do it through driver settings. Is my overcloc even working? thanks.
