GTX 1070 Cuda: Illegal memory access

[breezko]

OC Settings:

• Base Clock + 120MHz
• Mem Clock + 450MHz
• Voltage 745000

Algorithm: Dagger Hashimoto

GPU: GTX 1070

Running these settings results after a short period of time in a "Illegal memory access" error - as a fallback the NBMiner will be started after multiple retrys on excavator miner.

On NBMiner I got no issues with the given OC Settings.

What is happening?

Try latest version of QuickMiner RC 0.5.1.6 and replace with Excavator build 938. If that doesn't work, update NVIDIA drivers. Also, if you have high memory clock and you do not allow Excavator to set low mem clock during DAG generation, there is high chance of crash or generating invalid DAG.
