This is predominantly a support forum though, so people will invariably come here with problems. Typically we sell in excess of 20 million motherboards a year and we don't get 20 million new signups, so, we're doing something right 😉 Our X99 series takes 50% or more of the market in some regions so proportionally we'll see more voice on it even if the total % of issues is the same as the 'industry average' of a couple of %.
The MB RD teams keep an eye on these forums, among others, to check for common problems.
