Being able to underclock the memory and overclock the core in a way, which allows me to change frequencies from a script. Preferrably directly with the aticonfig tool, but another command line solution is also OK.System:
2x XFX HD5870
Debian Linux 6.0Current state:
phoenix 1.48 is running fine with 380 Mhashes/s for each card with clocks 900core 1200mem
ATI Overdrive is enabled, the aticonfig tool restricts me in ranges [600-900] [1200-1300] for core and memory respectively.
Cards are currently flashed with an ASUS BIOS which reportedly should have allowed me to do what I want, but doesn't.Already tried:
Using AMDOverdriveCtrl - The tools runs just fine, does nothing. A warning message in the console seems to tell me that this card does not support power states?
Flashing an ASUS image (see above) - Other than a changed fan characteristic curve (card is not as loud anymore - but hotter), no changes visible.
For a working solution I have no reservations doing any or all of the following:
flashing another bios on the cards
putting the cards into a windows (7 64bit) computer to do some setup or whatever
reinstalling linux, even another distribution, if you can convince me, that Debian is the problem here (don't know why it should be...)
I will be away from my rig until next monday, but I will have a look at this thread from time to time to comment on any questions. I also have remote access, so I can try anything which does not require physical presence
Your help is greatly appreciated.
