i was reading the back of my gigabyte 3870 box an found out the core has 55nm technology so i thort i must be able to OC this card far.
Q1 what are safe idle an load temps for it?
Q2 haw far have u gone?
 
any temps under 80C on load should be fine, and anything under 50C idle is ok too.

optimal fan speed is 50% says most review websites, so i would just set it to that and forget about it.

i have heard of people getting up to 850/1950 (i'm not sure about the last one) but as a rule you should always overclock by yourself instead of setting it to what someone else got.
 
For 24/7 clocks I have mine on 845/1201. They are both 100% stable on 885/1300. I am thinking of getting two Zalman VF1000 LED's for mine.

i can get those clocks stable in crysis, but COD4 is one of those very, very picky games when overclocking :(

I still need to get COD4, been meaning to get it for ages, still playing airborne online. On the COD4 Demo 885/1300 works fine for me. Have you read anything on those Zalman VF1000's? I can only find reviews on it with 8800's.
 
no, i haven't, i plan on getting duorbs for mine :)

COD4 freezes with the memory clocked past 1150 after about 1 hour of playing for me
 
Oh rite, I will have to have a look out for a review on it. Not played COD4 for over an hour so will prob have the same problem when I get it. Nice 3DMark06 score by the way!
