I did - but it doesn't work.

Someone I met told me it will only work with Catalyst 14.

But nevermind... I continue mining DCR - nearly the same profit with much less effort and problems.

For the 2GB cards, it is better to mine DCR.

How much memory your GC have? Must be at least 2GB, the DAG file is now above 1350MB.

The 6990 has 2x2 GB the others 2 GB.



For the 2GB one, I added this in the bat file:

setx GPU_SINGLE_ALLOC_PERCENT 100

Check ethminer --list-devices
Look at CL_DEVICE_MAX_MEM_ALLOC_SIZE

What does it said? (for both device)

Hey guys,

I just tried to mine ETH with my system. It has got 1 HD 6990 and 2 HD 6950. I use qtminer on windows 7 64 bit, catalyst 15.7.1

Start batch:
setx GPU_MAX_ALLOC_PERCENT 95
setx GPU_USE_SYNC_OBJECTS 1

qtminer.exe -s us1.ethpool.org:3333 -u 0x17C0Bea7c449Fa27e32D4cA9569EBA3d9B605CF2.rig1 -G


It creates the DAG but then says "clCreateBuffer(-61) GPU can't allocate the DAG in a single chunk"


Anyone got an explanation for this error?
