Anyone overclock the 512M 3850 ?
I noticed one vendor has a 512 version of the 3850 selling for about
$200 (bookmark that one Wondering if anyone replaced the heatsink/fan and overclocked it ? A little slower ram but should be good for the money compared to all the $270 cards. |

A little slower ram but should be good for the money compared to all the $270 cards. A few were briefly available on NewEgg, but I waffled a few hours too long and they went Poof! The Powercolor offering looks appealing with the high end 'flower' style cooler. This looks very promising: http://www.xtremesystems.org/forums/...d.php?t=166623 It seems the 3850 is set to run at lower voltage than the '70. Tweaking the power to '70 levels works wonders for the '50. One brave fellow has his running well at 1GHz. The voltage he's using is far above 3870 levels and seems pretty hot for a 55nm chip. IMO, he'll probably fry the thing sooner than later, but it's fun to see the magic 'G.' -Moo |

I've got the Sapphire 2850 (512 MB) and just tested overclocking a bit - memory seems to take another 100 MHz with no issue at all; GPU was at its limit much earlier (around 40 MHz more?), so I stayed at the original settings for now.
