Gf4 Digidoc Placement And Temp

[slacker73]

Just to put it out there I am a newbie

 

I have put a gpu watercooler on my video card

I have a digidoc5 and I was wondering about two things

1. Where on the chip should I place the probe(or whatever you call it)

and what should the temperature be....for now I have stuck it next to the die(?)(I think that is what it is called) and the temp reads 24 c....if this is true I know it is good...

2. what are the acceptible temp ranges on a gf4

And just a little bit of fmi(for my information)

The 133 in my bios setting is actually 266 for my ram(I am thinking that DDR memory on both the up and down of the clock cycle so it is actually double).....if not then my FSB is not 300 (due to my overclock) but is actually only the 150 that my bios shows. The xp 1600+ is 266 fsb...so this also leads me to believe that the system fsb is 266
