ok, thx anyway,
i was really annoyed with the new rig for a short time, as i had bad instability
and i think it was killer 2200 + avast antivirus, cause when either was turned off it would work, had to do quite some trial and error, though, before i found out,
thought it was the xeon in non workstation approved board or other bad scenario
chose to stick with the lan chip and went kaspersky for antivir
i can see why it (killer 2200) might come up as being buggy in forums and reviews, who knows what software else it interferes with
