Quoted from PanzerFreak:Many owners of 7.5 unbuffered and buffered games have never had board issues. Going on over 4 years here with 7.5 unbuffered boards and have never, knock on wood ECLE apron, had an issue.
I have a game with a build date of 10/24/2013 and it has the 7.5V un-buffered boards and I have only had two occasions in 4+ years of owning my WOZECLE with an LED light board lockup and a simple re-boot cleared the issue both times.
