Any ideas to what might cause this error msg
GPU 2, OpenCL error -4 - cannot create DAG on GPU
I only recently get this error, after some random number of watchdog restarts the gpu builds the dag fine, i tried serializing dag generation and lowering clocks neither has any effect.
Which GPU model, driver version, system RAM do you use?
The rig in question has several models 2 7950, 1 r9 280 (rebranded 7950), and 2 r9 380 (all Msi brand). On gigabyte ep-45 mboard q6600 and 4gb ram running win 7 x64. I have set all environment variables, 16 gb page file, 15.12 driver, though as i said before it was previously working fine and it does eventually build dag after some random number of watchdog resets.
Edit: On an unrelated note all 7950 and 280 cards on this rig only show 64% gpu load in gpuz, 380 cards show 100% and hash faster despite having elipdia ram (remaining cards are hynix).

Also my other rig 5 r9 280x all gpu show 64% gpu usage.
