5850 dont like the memmory underclocked for some reason i spent a good 8 hours flashing, reflashing etc etc the best i could get it down to without it crashing was 800 mhz. 5830s on the other hand seem to have no problem with lower memory speeds.
My 5850 disagrees with you.
It is running stably and at its best @ 950 MHz core/180 MHz memory. I guess it just depends on the individual card.
OP, read the first post of this thread (http://forum.bitcoin.org/index.php?topic=4292.0
) carefully, and you may need to change the permissions of the .cfg file first, as I did.
Yea I think it has to do with the individual card as well, I just for the life of me could not get it stable. Oh well its still pretty cool even with the higher mem.
As far as lowering your minimums rbe editor is the easist way to do it. Basically edit your bios so your fans are always 100%, ram mins and maxs, etc, etc there is a little bit of a learning curve to the software. You'll see what I mean
