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.

I have 4 Gb ram - not sure how much virtual memory but I once read that windows is doing this on his own.

IF you dont want to use proxy use this

ethminer -G -F http://us1.ethermine.org:5555/0x4bb96091ee9d802ed039c4d1a5f6216f90f81b01.rig1

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....

original eth miner

14.4 catalyst

Every pool works

Windows 7

I don't get the eth miner running.. I don't know what I need to set there.

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?

So, now its being recognised, but...

Code:

[0] Cayman
        CL_DEVICE_TYPE: GPU
        CL_DEVICE_GLOBAL_MEM_SIZE: 2147483648
        CL_DEVICE_MAX_MEM_ALLOC_SIZE: --->536870912<---
        CL_DEVICE_MAX_WORK_GROUP_SIZE: 256

Why only ~536MB?

BTW, chunked miner isn't working for me. It just stops after that:

Code:

Loading single big chunk kernels
Mapping one big chunk.
Creating buffer for header.

got about 13mh with claymore dual miner on radeon 6970

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.

You can have a look at the temperatures. The one with low temperature is not working, even though GPU is 100%.

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?

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.

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.

280x - 65C
6970 - 56C

so it's low)

I'm getting 26mh with 280x Gigabyte windforce 3x

so 19 mh isn't to much
Can be many crashing reasons ex. power adapter to weak, broken motherboard to software ofcourse

So you figured it out?

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