    boosting the voltage with nibitor is only going to make it so OC OV protection wont kick in youll need to pencil or solder on your card to increase voltage.

    very nice Dobbie! those clocks will make the 8600Gt fly :D and yes, praise be to this awesome forum, but also Solaris deserves your thanks as he single handedly made those 8600 guides, he is the 8600 god.

    although from experience i would say that you should be able to clock the shaders up to 1700mhz +, if you are using rivatuner, make sure the core and shader clocks are "unlinked" and go nuts. they clock up in steppings that are as follows:

    1404 - 1458 - 1512 - 1566 - 1620 - 1674 - 1728 - 1782 - 1836 - 1890 - 1944 -1998

    even though GPU-Z shows 1450, your actual effective shader speed will be 1458, and the rivatuner monitor will show accurate values. also i believe these shader increments apply to all geforce 8 and 9 series cards.

    oh and FIY, my 8600's run at 850 core 1836 shaders and 1700 memory, thanks to a little pencil modding that Solaris got us onto :D

    I tried the pencil mod but I don't have a voltage meter to see how much more I'm getting by doing it. I'm mostly just surprised that my first trails of VGA OC turned out so good :)

    if you tried the pencil mod you should be able to hit 800 on the core easily
    I did 890 on the stock cooler, although i did hit 105C on load :laugh: :eek: :D :rockout:

    I did try penciling it, but I only got about 20 more on the core before the driver started stop responding very few min so I don't know what to do now. After pushing more than 30 I ran into artifacts.

    If you want to go higher you're going to need to do the penciling ;)

    I'll give it a try again. I'll try and see if I can get a voltage meter from a friend to see what I'm really working with for voltages on the core and mem.
