First off I want to start by saying hello to everyone, I have several questions that I would like answered if possible. I purchased a 680 lightning from newegg (rma'd my last lightning 680 within a week). I'm a little worried about overclocking since I haven't ever overclocked a GPU, only CPU. I'm not very experienced but I'd like to push this card as much as it can go on air (stable of course). Would anyone mind helping me out? I've read lots of the replies in this thread and they are pushing numbers my old 680 would never even touch.
I previously overclocked my rma'd 680... got to the point where it could barely hit 80 on offset and 80 on memory. The fans stopped working properly, the card would go to 71c on 100% fan speed after 10 minutes of BF3 gameplay. Thing is when I first got the card it was running fine until I started to venture into overclocking. Is it possible that I may have been the cause of the issue? From what I read its very hard to overheat this card. At any rate, it was rma'd due to faulty cooling, I now received a new card with unlocked ln2 bios (same as my previous card, I guess its all luck?) Guys, it would make a great xmas present to have a successful overclock and a nice boost in my dx11 games.
System specs: i7 920 @ 3.6ghz, 8gb gskill ram, x85 msi mobo, 1000 watt thermaltake psu, v8 coolermaster heatsink.
My assumption was that you would first overclock every 20mhz, run a benchmarking program or play bf3 or any intense dx11 game, if stable repeat the process until you crash then go back and reduce 5mhz. Now do I go to memory do the same or should I up the voltage and continue on the core? Ambient temperature is 71c, however that is near my case and monitor which I assume gives off a little more heat than other places in the area next to me. I understand this is probably such a repetitive question but I'd like to get into hardcore overclocking at some point and thought this site is the best place to start for advice.
Thanks for any help that is provided, its much appreciated!!!
