Ive allready milled the original sink to be perfectly gapped to the gpu and ram chips .the do have different heights, which is why you typically put a bigger layer of compound on the ram chips then the gpu. So I got a excelent and even surface contact now. Its just what to do with the fans and this (atleast to me) abnormal voltage. btw you said RT dont measure volts then Im assuming the RT monitor isnt a real time voltage measurement tool then? This is where I seen the 1.6 I wasnt worried what the RT probe reported. I go by what things are actually doing not what they are 'supposed' to be doing.
Forget what you measured at the regulator chip, since it is only what gets to the GPU that matters. And as I said, without a direct hard-mod to the card, the hard-wired MAX available volts to the GPU of a 6800GT and 6800Ultra is 1.5v. Which obviously means the 1.6ish volts you are measuring is not GPU volts !!
And yes, RT is NOT a real time GPU volts monitor. So if RT is indicating a GPU volts level of 1.6v then you are either using an incorrectly
modified bios, or you didn't properly setup the hardware monitoring VID section of RT; or maybe both ?
