Hi Jim, This is the information sensors gives you that identifies your chip: > Probing for Super-I/O at 0x4e/0x4f > Trying family `ITE'... No > Trying family `National Semiconductor'... No > Trying family `SMSC'... No > Trying family `VIA/Winbond/Fintek'... Yes > Found unknown chip with ID 0x0541 I am going to guess it's a new chip not seen before. The MSI K9N6SGM-V uses the nVidia MCP-61 chipset. I downloaded the manual from: http://www.msi.com.tw/program/support/download/dld/spt_dld_file_record.php?folder=3&kind=1&name=M7309v1.1.zip (JAVASCRIPT WARNING) In the manual on about page 4, there's a diagram showing the board layout. If this is accurate enough, then the hardware monitoring chip *must* be integrated in the nVidia MCP-61. The chip is probably only recognizable by the chip ID 0x0541. I don't know what chip it is. Hope that helps, David
