\[Solved\] Anyone got ADL (temp, rpms, adjust mhz) under linux for cgminer?
-
I’m getting a bit desperate here. Nothing I read tells me what I do wrong. I just can’t get it to work, that’s that. Cgminer runs and plods away at about 560 Kh/s per 7950 GPU, but I could get more out of those cards if I could adjust some settings. Anyone got any ideas?

[/quote]I think ADL has nothing to do with your hashrate, since it is only reading out the sensors from the GPU.
I have noticed when using cgminer under linux, that the speed depends very much on the SDK & kernel & fglrx you are using. I was not able to figure out a system behind it(which driver works best for which hardware setup).You should check if all headers & libs(.so files) are accessable by the user you are starting cgminer with. If AMD did not fix that yet, the drivers do not set up access rights correct. (debian wheezy, fglrx 13.1, files have been only accessable by root, but most people do not like to login with root under xorg^^)
You might pm me with some logfiles , if you cannot solve this. i will try to figure out what is wrong.hynodeva dev

Thanks for the reply, I forgot this thread was still there. I actually got it to work.
ADL is needed to get decent speeds and get it all safely, because if ADL is not compiled in correctly and working, you have no access to the memory and engine clocks.
I’m now doing 650 kh/s steady at 73C on a 7950 with < 1 % rejects and no HW errors. I haven’t done more tweaking with it yet, but considering the max was about 540 at stock, that is a success in my book.
I use the latest combo of all those parts. Still need some time to clean up the mess of my notes then I’ll publish a guide for it.

Ah ok, changing mem & engine clocks is a good reason to need ADL^^

Would it be possible that you share your settings? I also have a 7950 (now) which i plan to use… ;-)

Will do. Off the top off my head its memory at 1575 and core at 1080 with intensity 20. But thread concurrency is very important, so I still need to look that up :) -
In reply to your OP, I have it working, although I can’t remember how I did it now :P as it was back in January :(
I know you have to enable overdrive for your card and if you can’t do this (repeated errors when trying etc) then it is a driver issue that you have and not an (ADL)_SDK one - You [i]may[/i] be missing some additional necessitated libs on your sys… Although what ones I have not got a clue, I know I spent a good few nights trying to set mine up, a real PITA if ever there was one >:(
Good luck!

[/quote]Thanks I got it licked perfectly now. Gotta doa proper write up, then I can post that too.

Great news and yeah it would be good to have a write up for reference purposes as it is a nightmare trying to find constructed information online…As you have already found out is the case :)

Nightmare on stackoverflow/bitcointalk. I was thinking that everyone just uses windows boxes because it never works on linux.
Have something else small cooking here. So this guide is a tiny bit on the backburner.
