I am getting about 320 mhash for each of my 5850s with
Clock: 875 and Memory Clock on 300

But i read of people getting about 400 mhash :O

If i am going higher is the only thing i need to watch the temperature?

Temperature and stability. My XFX5850 won't go above 850Mhz stably when being used as a "normal" computer and running a miner.

Someone said with 11.6 you can overclock past the bios limits on Linux? Is this true?

It's better to be pissed off, than to be pissed on.

Yes its true, was running 975/300 yesterday but desktop freezes if
I watch tv with kaffeine Cheesy now running on 925/300.

SDK 2.1 helps alot

I run 900/300

with 2.4 i get 335-340 with 2.1 i get 350+

SDK 2.4 with phoenix and option -k phatk works also good,
my other machine is doing 359 Mhash with that.

I can push some of these to about 920mhz, after that they tend to freeze even if I just look at Afterburner with remote desktop for 5 seconds so I don't deem it very stable.

If you are also using the PC for general stuff like surfing or reading forums, about 870-900mhz seems ideal, and you will get at least 320-330mhash/s

It's mainly luck. I can push my best card to 950 MHz on stock voltage, and the worst only to 850.
