Overclocking 2x 8800GT

I'm not not much of an overclocker so I need an experienced person to give me a little advice.

I have 2 8800GT's which I want to overclock with EVGA precision. My case has good cooling and with the fans set to 60% they never get to 70 degrees.

What I want to know is the best way to overclock these cards - do I do it in increments or can I put the sliders all the way up?

Also, what ratio does the core/ shader clock have to be to the memory clock? Say if I move the core up by 10 points how much do I move the memory clock up by?

Finally what's the difference between linked and unlinked?

Cheers

which will be done by restarting computer and constantly keep pressing the F8 key, not held down but constantly pressing, and go to windows in safe mode, and do a system restore and it will put you back where you were before you started tweaking

but not sure if evga are as overclockable as the BFG version so i woul do the core in increments of 25, while the other two in increments of 50... hope that helps.

other info... im running 2x 8800gt factory overclocked times 3, meaning instead of 600 for the core its actually running 700.. I love BFG.

Chhers for the info

How long should I leave it between overclocks, and should I do any intensive gaming to test it out?

Cool, I'll give it a go! Will I see much difference once I get it to full speed?machine_B

what do you mean full speed?> in no way should you put your core clock over 120 than it already is.... it could get dangerous then...

but you might see your minimum frames per second increase (slightly) but as far as your average not really... and your high fps not really... but you might.. you might. i doubt it will decrease preformance :P

sorry i meant max as in max amount I should do. Hmm not a hude increase then? Ahwel I'll take anything lolmachine_B

then a few months after that upgrade power supply and get a second bfg OC2 gtx 280 for SLI out of this world lol, well that is ofcourse after the gtx 280s get below $400 before the rebates. which is not gonna be too far off.. estimating by the end of october... beginning of november.

I doubt you will see a blue screen if you overclock too much. What will happen is you will see artifacts and just strange graphical glitches. First move your core up in small increments(10-15) and use ATI tool or just play a game and look for artifacts or graphical defects. If it does then set it back a little and test it again untill you get solid performance.

When you get to a point where you can't move your core slider up anymore because of artifacts then move on to the shader slider and do the same thing as the core. And just leave it linked and it will be easier. Just go slow moving your sliders up cause if you go up too high your PC might lockup when you test it on a game.
