Please let me know if you are using 1 memory stick of 4 Gb or 2 sticks of 2gb each?
Some other recommendations would be to update the BIOS to version 0096, since it “Fixed issue with LAN packet drop” https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=22024&ProdId=3437&lang=por&OSVersion=Independente%20do%20SO&DownloadType=BIOS
Then you can update the BIOS to version 0100 https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=22561&ProdId=3437&lang=por&OSVersion=Independente%20do%20SO&DownloadType=BIOS
Something very important that I will like to inform you, it’s that you are using a desktop board not a server board, therefore the performance will be different.
Then, Windows XP is not totally compatible with this board, there are some drivers available, however support is limited due to discontinuance of OS.
I am using Win7 pro 32bit
tomorrow I'll try and update the bios.
Has a link with instructions on how to update the bios?
Did the procedures and the board is working normally!
