Hey Community, i know there are many threads from this old hardware but i think this is a new "Problem" :-P
Ive got an Club3D ATI 6950 in a Rig from me, i know the Card got the Problem of allocating one big chunk of dag file. Anyway i saw that Genoil got on Github an Chunked Version for the Intel HD6000 (i think its for intel^^) and thought lets give it a try because all other Versions of ethminer failed because of the DAG allocating Problem. Anyway the Version for the HD6000 seems to work, ive just get 4mh/s but thats more than nothing.
If i can help u guys with a version for the 6950/6970 i can give u full remote access to my rig to test ur software
hope to get an answer
best greets from germany
