So you figured it out?
The 6990 gets like 16MH/s in total. You need to undervolt because it will run at 100C.

got about 13mh with claymore dual miner on radeon 6970, about 19mh with 280x. both cards about 32mh
catalyst 15.7
but rig is rebooting after 5-10 minutes...dont know how to fix it now, still trying...
also look like it is impossible to run 2 instances of ethminer, chunked for 6970 and latest for 280x - ethminer is crashing

I think your temperature is too high, you need to reduce the voltage of the VCore. It is too hot to mine stably.

I'm getting 26mh with 280x Gigabyte windforce 3x ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) so 19 mh isn't to much Can be many crashing reasons ex. power adapter to weak, broken motherboard to software ofcourse

That's would fit to my problem that it does only show 13 Mh. I think it does only use one of the 6 cards. But gpuz shows 100% load for all cards... I have no clue I just tried the claymore dual miner. It is rocking at an increadable fast speed. It could create the DAG on only 5 of the 6 cards but still has got over 50 MH/s. That would mean if I get it running on all cards I get like 60 MH/s - and I haven't really overclocked yet.

What clock and memory is your 6970 set at to get 10mhs ?

910 MHz core clock 1280 MHz mem clock At 1,1 V And it's very cool - never gets hotter than 55 degrees. I was running decred before with 950 MHz and no problems. So if all is working I will go to that clock again - but first I need to get it running..

I got one core at 830/1375 1.025V gets 8MH another at 750/1275 0.975V gets 7MH Any higher voltage and the 6990 runs at 90C. This 6990 had a long hard life first with BTC mining, then LTC mining, then X11 mining and now ETH mining. Worth every penny from back in 2012.

My 6990's have a twinturbo cooler. The hottest I can get them is 68 degrees by mining decred with 980 / 1200 / 1,18 V.
With the forked miner I get only 45-50 degrees.
You are running a 6990 on eth?
What miner? What driver? What pool?
I still can not get them running with more than 15 MH/s for 6 cards....

I just installed catalyst 14.12 - with this version the genoil miner get's 19-22 MH/s - that's better than the 14 MH/s before... but still far from the possible 60MH..
@Genoil any suggestions from your side?

The one with low temperature is not working, even though GPU is 100%.

I installed the original one - I have the folder with the ethminer.exe And I want to get this pool running: http://ethpool.org/But I don't know what to do with these proxy things and what I need to set up to get it running - could you please help me?

I just found a step by step guide.
But with Catalyst 14.12 it did not work... still tells me that it can't find gpu's for the DAG.
Now I'm installing 14.4 again.

Make sure you have at least 4GB ram and 16GB virtual memory.
