Do we have an update on this ?
I'm ready to commit BTC for someone to find a solution.

(don't want to flash the bios)

I find CGMiner is better than pheonix and updated weekely and more. It was designed for linux i believe to but works on everything. I actually use windows and the 10.4 with 2.1SDK ruled for a while but CGminer got better with the new drivers. 11.7 all my systems are now with 2.4/2.5SDK, the one that comes with 11.7 anyways Smiley

No trixx for linux? i thought catfish was able to overclock 5850's in linux though???

All I do is use the 11.6 ATI Catalyst proprietary drivers for Linux, then the 2.4 AMD APP SDK, then simply use aticonfig to shift the clocks around.

Nothing special - I don't see what the problem is here. The problem I *have* had was getting aticonfig to do anything with 6950 cards - in the case of the 6950s, I needed a copy of Windows, the Radeon Bios Editor and had to flash the cards.

But for ALL of the 58xx cards I have (5830s from XFX and 'Peak', and 5850s from Sapphire (extreme and 'proper'), XFX (black edition)) - all I need is to use aticonfig.

Once the Catalyst drivers are installed, don't forget to run aticonfig --od-enable --adapter=all so that the 'overdrive' is available i.e. overclocking.

For my original 'old' Sapphire 5850, with the five fat heatpipes, a simple command of 'aticonfig --odsc=990,300 --adapter=0' will have it running 404 MH/sec under phoenix with the July 17th phatk mod.

I've only ever had problems overclocking cards with the 69xx series, to be honest.

I'm using Ubuntu 11.04 'natty narwhal' with all updates. I've tried the latest 'oneiric' and it doesn't work with pyopencl and boost.

What I *cannot* do with 5850s in Linux is to overvolt the cards beyond 1.088 - I can undervolt the cards (very handy for the 5830s, which have a 1.125V standard voltage, but run fine over 900 MHz core with the voltage turned down to 1.100V) - but *not* overvolt them.


I think this is what the OP was getting at. It's easy to over*clock* 58xx series cards in Linux, using ATI's own tools. But over*volting* isn't possible without additional tools. I've standardised on AMDOverdriveCtrl for my overclocking on my Linux mining rigs now, and that can't overvolt either.

So if the OP is desperate to overvolt, I suggest the 'Radeonvolt' thread is the first port of call... personally, with the cost of electricity and the profit margins from mining getting negative, I'm in the process of undervolting cards to the edge of stability, plus getting my electricity tariff changed over to an 'off peak saver' plan where I pay less for night electricity Smiley

...so I give in to the rhythm, the click click clack
I'm too wasted to fight back...
