Users with Mykerinos MYK-X50 are advised to stay off upgrading their existing system to any i5/i7 platform.
More info about hardware (in)compatibility can be found in the Forum, Support section, here: viewforum.php?f=26
Can´t find the explanation for this in the forum. What does this mean? That people that bought the X50 can´t upgrade their system? Hummmm....
