I've seen some used CPU offers on ebay, with very attractive price tags. However we are being told that the cpu is an 'Engineering sample' and can not be used on servers in Europe and North America.
I know what engineering sample mean however still wondering why one can not use the engineering sample cpu on servers? Are they technically unstable for production? Or there are some EU/US laws that prohibit their usage? Or it is simply the sellers disclaimer that they can not guarantee them? Or something else?
