Is it normal for a 5850 to run at 900 mhz core stable at stock voltage?

...cause that's what mine is running at right now (doing ~340 mhash/s)

I have mine stable at 918 (as far as the slider goes) on stock voltage, but I also have it under 75c, so ymmv.

i'm currently running 2 5850s in xfire @ 950/300 1.15V.

get about 359MH/s
1.15V is golden middle voltage.
but clocks higher than 950 is dangerous, cuz usually guys not care about VRM/power system circuitry cooling improvements :/

lucky exemplar can do that, but majority need slight voltage tweak [about 0.05V] to reach suck clocks.

if an overclock is unstable enough to artifact while playing games but not unstable enough to crash, how would that translate to bitcoin mining?

(im not saying im getting artifacts or anything like that, just curious)

My 5850 is semi-stable at 860/1190 but I can't run games for more than an hour without the clocks resetting. I can mine fine, but I'm likely killing my card faster. I wish I bought an Asus reference card so I could up the voltage and get a nice 1000/1300 overclock going, the model I bought is voltage-locked at 1.15v. Weirdly though, when I installed the Trixx overclocking utility I was able to change the voltage and it reflected properly in GPU-Z. I OC'd until my system became unstable but upon restart I lost all software voltage control. Bloody strange.

Depends on what model it is, but yes, many around here have achieved that and more.  Search is your friend.  Or did you just want to brag?
