the safest common speed for sapphire Xtreme is only ~830mhz @ stock
or I must be doing something really wrong...

Damn... that's a lot...
I'm getting about 372 mhash/s.
940/1000 at 1.125 v, I use the computer for other things as well, that's why the memory clock is high.

that is exactly what I run mine at. anything more and stability suffers for the most part.
sure i can increase the clock and it will run higher for several days on end but eventually
it screwed up and would be down for several hours until i noticed/fixed it (always at night)
thus defeating the extra mh/s i was getting.

I had 434.4 with my HD 5850 ^^

Check that thread out for some past attempts.
I hit about 432.5 (think it was at 1010 Mhz core) but I didn't run very long because I was worried about VRM temps (114c). I think teukon even went further than that but I lost track of the thread thereafter. Instead focusing on energy efficiency as being that high voltage decrease the actual amount of bitcoin worth earned.
At any rate, my old reference 5850 (the one above) seems to get more Mhash than my second non-ref 5850. Ref version is at 920/320 1.1v and gets 397MH/s while my other non-ref is at 975/320 1.088v and is getting only 404MH/s. Tried to replicate and even installed it on my system where the 5850 ref is but no go. Just a different beast.

What sort of voltage do you use?
i make
398,8 mhash
core 964/310
398,8 mhash
core 964/310
What is the highest hash rate that someone achieved with a 5850 without blowing up the card?
Just curious.
