Thanks for any help!
This is the big risk with solo mining, especially when your average is 15 days. You can go 90 days and not hit a block and it can be variance or there could be something wrong with your software. Since you haven't hit any blocks with the new software, its impossible to tell whether its variance or something wrong with the code.
I think only Claymore can investigate this since I am fairly sure that 99% of the people here all pool mine.
Is there any reason why you are solomining? Is it just to save the 1% of the fees?
My advice, just switch to ETC mining for a few days and you should hit a block faster, if you do then obviously the setup works and you just hit bad luck, but if you can't find an ETC block then something wrong with the software.
I'm aware of the risk of solo, I always enjoyed it and likened it to gambling. I was able to sync the ropsten blockchain (testnet) and mined against it and hit block rewards, which would indicate the software is setup correctly. The only thing that ropsten doesn't replicate is the post-300th DAG. I just thought I'd see if anyone else crazy enough to solo mine was experiencing the same issue. Mining ETC would be a good recommendation since its on epoc #316.
