    Need a bit of advice/direction please guys.

    Just got a new shiny GTX 470 courtesy of DaTLiTe :thumb: After having a mess with it for about 30 minutes early this morning I'm wondering how far to push the overclock for everyday use. By everyday use I mean it'll be overclocked when I game which is about 2-3 hours a day. The rest of the time it will run at stock. (The fiancee's facebook habits don't really warrant me pushing the card lol).

    I bumped the core voltage to 1000mV because it's a nice round number :D It was a 13mV increase in case you didn't know.

    On this it's stable at 750/1500/1750 with a temperature of 68C after running FurMark for 10 minutes.

    Just wondering how much further you guys would push it and what a maximum safe(ish) voltage and temperature would be?

    Thanks

    GTX470s are (or should be) amazing overclockers - it's one thing I miss about mine!!

    I pushed mine all the way to 1087mV (with good cooling, mind you) and the best clocks I got were 865/1730/1924. If I bumped the memory just one notch it would fail a 3D bench, but with these clocks it would sail through anything including Heaven (extreme) and any Futuremark test.

    I generally don't OC video memory because it's a waste of effort; core/shader are the clocks that count, and if you are going to overvolt for stability, use the extra juice for core/shader!

    For a daily OC I'd recommend going as high as you can on stock volts - you might be surprised how high you get. I only ever used 1087mV for benching... for everyday use, I was at 987mV and stock clocks.

    Don't see 1087mV causing any damage other than that it might make your temps unnecessarily high; and for temps I'd say up to 90C would be my threshold, even though the GPU can take it easily. My 470 topped out at 80C, but as I say I had very good cooling (120x120x38 fan). :thumb:
