So I've rented other rigs maybe 15 times, decided to offer one of mine up last night. Absolutely rock solid rig with the old faithful 5870's in it that just never quit, it's been running several months on numerous scyrpt coins without any issues. Woke up to an email from renter saying rig is rejecting all shares and to compensate him. I find 3 dead cards in rig and absolutely no clue what algo he was trying to mine. What kind of checks are in place to make sure renters aren't pointing to wrong kind of algorithm or other such mistakes that could cause hardware issues? luckily all the cards came back after being powered down for several minutes but I have to say I don't have a good feeling about this all
