With Phoenixminer I can mine coins with over 4GB Dag.
Please.. Any idea???
Drivers!
If you have old drivers, then update them. I noticed this problem with AMD video cards, when they gave such an error with the amount of information exceeding 4 GB, which needs to be used for the DAG file.
You are right. After my post, I tried to mine ETHW with TRM, which had about 6GB DAG, and it worked fine. I see at DAG generation "dual buffer mode":
GPU 0 Running kernels in dual buffer mode.
GPU 0 Starting DAG generation for epoch 618, 5.83 GB (dual buffer mode).
Kawpow algo run in "single buffer mode". I found command "--eth_dag_buf" to force buffer mode to Dual, but looks like it doesnt work under kawpow algo.
In usage.txt file I found, that older drivers not supported single buffer mode over 4GB. Unfortunately I really use very old driver (19.12.1), because all my cards works perfectly with it.
When I upgraded it to ANY newer, I had always some problems.
Can I somehow forced this Dual buffer mode on Kawpow algo??
