I need in detail instructions. Not too basic though as I know how to overclock a CPU.
Also what tests should I run to make sure it's stable?

what card and how much do you want to overclock?

just some ideas to make things easier in the long run..... has voltage meters which you can solder into your pcb for real time voltage measurements. Why is this a good idea? then you can see stability while under load as well as view your real time settings of the variable resistors that you should use to adjust voltage. Why use a vr instead of a carbon film resistor? Simple, say you want to update your drivers, reformat your hard drive, or simply troubleshoot a glitch. With a variable resistor you can simply adjust the voltages back to stock and then use your software utility to downclock the card to default. Utilizing the soldered in digital voltage dislpay means you dont have to crack open your case to use a multimeter or worry about a multimeter being on the wrong setting when youve had a few beers:-)
Just make sure that if you order one of the displays that you get one that doesnt draw from the line in which it measures or your overclock wont be stable. I have a few for mine that I used old case to motherboard pin wire to connect them to molex connectors. If you need help with them then just pm me and I can get you the model numbers that I use along with some pics to help you hook them up:-). They are backlight also so if you dont want to carve them into a cd bay blank then you can simply velcro them next to the card inside of your case window. I rivited my window and placed the vr behind the rivet to allow a tiny flathead to be inserted for voltage adjustments.
I dont know much at about current nvidia cards however I am familiar with most of the pcb for the built by ati cards as well as the controller chips internal diagrams. Finally, cooling is da bomb. The more you have the further youll go as Im sure you know since you stated that you are familiar with overclocking the cpu. You still must be carefull though since under 3d apps the gpu heats up very fast so your cooling should be as overkill as possible to avoid a too little too late scenerio. You want eveything as easy to acess as possible to head off any possibility that stumbling for a meter and a screw driver might prevent you from downclocking your card before it fries. I highly reccomend lian li temp displays as they are simple to use and really accurate, and really fast responding, not to mention really cheap! You dont want to have to stumble around a digidoc5 trying to find your gpu temps when your running at a high overclock no matter how cool they look.
