so i just received the board now and everything works fine, especially the overclocking but there is one big problem:

The Network connection is so slow that every page just need hours to open and downloading is impossible, don't know whats going on...

I'm using Windows XP x64 and the latest Marvell Yukon Drivers from their website and i also tried it with the drivers from the packaged cd but there is no chance...

Rest of my HW:
Abit AX78 Bios 12
4GB Gskill - DDR1000
AMD 4850e @ 3,0Ghz (261x11,5)
X1950 Pro
X-Fi
Hitachi HDD
Antec Earth Watts 380

does anybody has an idea, because i need internet on my main pc,
this is soo strange :/
