Title: ETH DAG allocation error Post by: 1337leet on March 23, 2016, 03:15:44 PM 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?

Look at CL_DEVICE_MAX_MEM_ALLOC_SIZE What does it said? (for both device) Title: Re: ETH DAG allocation error Post by: Charloz24 on March 23, 2016, 08:51:03 PM How much memory your GC have?

For the 2GB one, I added this in the bat file: setx GPU_SINGLE_ALLOC_PERCENT 100 Title: Re: ETH DAG allocation error Post by: 1337leet on March 23, 2016, 09:15:34 PM How much memory your GC have?

For the 2GB one, I added this in the bat file: setx GPU_SINGLE_ALLOC_PERCENT 100 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. Title: Re: ETH DAG allocation error Post by: Jitmad on March 25, 2016, 07:53:02 AM I did - but it doesn't work.

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