The guys from Hexus.net spotted a very striking motherboard at the German electronics fair Cebit. This is an ECS board equipped with a SiS656 Northbridge with support for Socket 775 Intel processors and DDR2 667 memory. The accompanying SiS965 southbridge provides connections for, among other things, SATA2, Gbit LAN and Firewire. So far nothing special. However, the board also features a strange PCI Express slot that seems too far back. This special slot can be used to use processors with a different socket. These types of boards have existed for some time, but in this case it concerns not only sockets from the same processor manufacturer, but also CPUs from competitors.
This Intel board can be converted into an AMD system with a special circuit board. The expansion card is therefore equipped with its own Northbridge, processor socket and a set of DDR memory banks. On the CeBit, the board was equipped with a Socket A expansion card with a Sempron 2200+ processor on it and everything ran like a charm. A Socket 939 card was also shown, with a SiS756 northbridge on it, so that in addition to Intel processors, the motherboard can also handle the latest Socket 939 Athlon 64 processors from AMD. No prices or dates on which this board and the accompanying expansion cards will be released have yet been announced.
