ASRock are known for its cheap and, for the price, well performing motherboards. It also has a rumor of offering some really unique solutions, e.g. motherboards with both 754-pin and 939-pin sockets. ASRock 939SLI32-eSATA2 is kind of like that since it comes with ASRock’s special expansion port which makes it possible to upgrade from Socket 939 to Socket AM2. By buying an expansion card you can therefore upgrade to AMD’s latest generation without having to switch motherboard. At OC Inside they’ve taken a closer look at this solution and the fact is that the board overclocks quite well, despite the odd solution.
