I got a new EAH5850 this week and i'm playing with it. No matter what i do (overvolt, underclock memory, overclock memory, undervolt, etc) i never
get an stable system past 850mhz, i've read some reviews of this card and they can overclock this baby over 1ghz, but i'm stuck on 850mhz
I bought a new PSU to feed this card, 750w modular, so I don't think that is a power problem.
I tried Asus doctor, MSI afterburner, trixx, aticonfig (ubuntu), and in all of cases i end rebooting the machine.
I'm getting 330mhash/s, 850/300, stock volts, phoenix + phatk + windows xp + sdk 2.4.
Any advise to get more juice with this card?
