I've also got roughly 40% bad shares, and none of the logs will open from the menu for me to try and do any of my own troubleshooting.
Might help to mention that I'm using the GUI miner, set to Smart Miner, which at this time has been on XMR for both CPU and GPU, with FCN set for merged mining.
Anyone? Opened a ticket as well, but thought I might get better / faster information from here.
thanks!
UPDATE, setting my GPU intensity (unsure how I missed that) to 2-4 dramatically improves the GPU speed, however it causes alot of GPU kernel crash and recoveries. Because of the frequency of the crashing, I got a warning that the miner has been blocked from accessing my GPU.
Looks like I'm running stable on Intensity 2, but the GPU speed doesn't appear to be stacked with the CPU when looking at the website dashboard, so I can't tell if it's actually doing anything. Still having issues with high failures, and can't use the logs in the menu. Calling it a night and will hope its better tomorrow.
