SiS755 Based Reference Board: Closer Look

We tested the performance and features of SiS755 using a reference board from SiS based on it. Now I would like to say a few words about the board, of course:

Once again, the PCB design of SiS755 based reference board is the same as that of the SiS760 based one, so these two chipsets are truly pin-compatible. As you can see, the mainboard has a landing-place for the memory of the local frame buffer. I do hope we will be able to test SiS760 soon, too.

I don’t think it really makes much sense to dwell for long on the reference design of the SiS755 based board as this mainboard has nothing to do with the actual products. So, I will just show you a few snapshots:

SiS755 North Bridge

SiS964 South Bridge

Mainboard rear panel.

Note the six USB 2.0 ports at the back panel of the board. We also have non-operational TV-out and D-Sub connectors here, as SiS755 doesn’t include an integrated graphics core.

A small passive heatsink is mounted on top of the chipset; the local frame-buffer should occupy the neighboring spots.
