OCing gfx card

So I'm getting adventurous and am thinking about OCing my newer 6600 GT. All I got so far is RivaTuner 2 anyother pointers or cautions?

If you smell smoke you do what's called a "quick" shut-down. It involves your hand and the cord flying out of the wall.

Other than that, the rule with overclocking anything is ALWAYS use baby steps. Yeah, you might be able to get a 5% OC or a 12% OC or... who knows. But always go in VERY small increments-preferably the smallest you can with your software-and give at least 2 hours or so at that speed to check for visual artifacts. My $0.02.

OC a few tips. I have my 6800 GT at or above 6800 Ultra speeds.

Your graphics card should have a temp monitor in the driver control panel for the GPU. This is your best friend. Watch it closely. It should also alert you when you reach a unsafe temp.

Take it in very gradual steps. It took me about a month (on weekends) to get mine as far over clocked as I have it. Do not slam it to see how far it will go. All you will do is piss of the computer, and os and make it immedately turn off.

If you have good cooling (case, psu, cpu, gpu, chipset etc), you temp gain on a well made 6000 series should be minimal. Something people dont think about. When you take a card up to extremes it draw ALOT more wattage from the PSU. You need a stable high wattage powersupply.

If the custom control drivers from you manufacture are good they should also allow that the card goes to non-overclocked mode when doing standard desktop stuff (web browsing etc). It will auto over clock when dealing with intense 3D rendering.

Patience is the key word.

Run it at stock speeds for a while first. Stress it out. They tend to overclock better, when burned-in a little. Be careful or you will have a $200.00 paperweight. To me, overclocking the cpu/fsb will gain you more. Alot of games are cpu limited at certain resolutions.

Ok so I'll take it slow and put an external fan on it hehe.

How would I go about overclocking my cpu?

And they say not to have it load your settings at windows startup, so how do you get the OCed settings to take effect? or does it happen when you start a game?

Depends on your mobo and cpu. My cpu is a locked Barton, which I could unlock if needed, but I set my fsb up from 166 to 200. Make sure your memory can handle it, if you choose to up the fsb. You can also change your multiplier to a higher setting, if you can or want to go that route. My motherboard has a locked AGP port, which is nice. Even if I up my fsb, the AGP bus always stays 66mhz, so it is stable as can be. All these changes are made in your bios. Some motherboards don't let you change these, so I am not familiar with if your board can do it or not. Extra cooling and a nice P.S. would help you out if you plan on doing this.

OK so I found out that my drivers have this automatic optimal settings button for overclocking so it pretty much set itself. But the cool thing is that it's gone from an eVGA 6600 GT with core at 500 MHz and memory at 900 MHz to a one with a 570 MHz core and 1043 MHz memory.
