Searching through this thread, I saw some fairly alarming posts from folks who said mining vertcoin may have caused some damage to their cards. Has anyone else experienced this?
Nothing so far. A higher state of instability with an R9 270X is about the worst thing I have encountered. On the other hand, I installed a 270 last night and I have been able to get about 224 kh/s out of it, but I have to tweak my car arrangement in my rig because this card is running ab it too hot so i scaled it back to 201 kh/s for now. My 270x is only running around 180 kh/s right now.
