Well he did seem to get past 500mh/s but i really doubt it was stable considering he is at stock voltage.

I highly doubt any card can stably get to 500. I was surprised when I found that. I went to that thread expecting about 480. The only card that can get there would be the 5870 though. |

With only 21 pool shares, that doesn't count. Show something that can run 24 hrs at that output.

Like I said above you cant realistically achieve that with any card that exists. You might be able to get 480 consistently (maybe) if you water cool your 5870. |

A p4 can sustain 8ghz under liquid nitrogen i'm sure a 5870 could go well past 500 with similar methods. That being said the cost involved of maintaining that even for an hour would outweigh anything beyond the I did it factor.

Stock voltage? I was running it at 1.35v. Problem is the heat now. It's been at record highs in Colorado but the forecast seems to be getting cooler so I may try to see if its a few hours stable. Don't want to risk killing my precious GPU, had it for nearly two years.  |

Oh sorry, i thought that was core speed...For how long was it stable tho, and any...artefacts or unusual behavior after the stunt? My 5850 ran overclocked for two weeks(24/7 mining) and started having artefacts, so your 5870 shouldn't be different. |

What speed and overclock was your 5850 running at? |

950/475. Then this weird black screen freeze happened and nothing but a cold reboot fixed this. I know i should have reacted the first time, but it happened around 15-20 times like that, afterwards i tested the card at stock speeds, and i immediately got artefacts and the same freeze. Didn't mine on it for a while, afterwards when i started it i left it run at lower aggressions and so far i didn't get any problems with it. Tho my 5870 also did experience this, so i am running lower aggr there too, and much lower clocks

Try lowering your mem clock to around 300. I've heard anything around 500 messes with the timings. If you say you cant go lower then 475 I had this problem too and it was fixed with trixx and a reinstall of my drivers. Also what temp is the card running at and how long have you run it that way? |

Memory varies by card. I have a 5870 that runs at 1000/500 any lower on the memory is unstable.
