Tytanick,
Several of us have posted about our ongoing issue with unstable cards that started a couple days ago, and with the exception of one dismissive post, you have refused to address this issue. I'm happy that you are opening your OS to new customers with the introduction of Nvidia support, but how about a little support for your established client base? Who knows, the problem may be caused by a third party, such as Claymore, but there is no way to tell as long as you ignore our concerns.
Offer him (or someone) money to help you troubleshoot.
He is not being funded to develop this... its all on him if it fails. He has no malice toward you, he just has time to either develop or to trouble shoot individual cases. Development is (obviously) more productive for him.
Someone here said that moving to Claymore 9.5 solved the issues, Tytanick himself said that he prefers 8.1. I actually find that 9.4 is stable and that it gets more shares than 9.5...
Now, YOU go and take some time to try different options and get back with a more complete analysis so that he (and others here) can better understand your issue.
I and others tried changing Claymore versions, it didn't help, and wrote about our efforts here.
