I am having the same problem. I hope someone can help.
System:
GA-EP45-UD3P, 8G Ram, 6X1TB SATA in Raid, 1 SATA for OS, ATI HD 4670 Graphics running HDMI and VGA to HP w2408 and HP2338h monitors
Running Win7 RC7100 clean install with no other software loaded.
Symptoms
1) When I copy a large file across the network to or from the system with the GA-EP45-UD3P, the connection is eventually dropped. Most of the time this happens within 30 seconds.
2) When I queue up downloads from the internet via SABNZBD, the connection drops within 30 minutes. If I go into the network icon in the system tray and troubleshoot the connection, it resets the interface and everything works ok until I copy another large file or do a number of consecutive downloads again.
3) NO PROBLEM if I copy from the OS drive to the RAID array or the other way around. I have also copied to and from USB hard drives with no issue. This leads me to a network issue.
4) Have tried multiple LAN Cables, 2 different netowrk switches, and 3 other devices attached to this system (Laptop, AppleTV and Netbook) All three cause the same issue (network on the Gigabyte Mobo system loses connection)
It appears that it is having issues with sustained or maybe high throughput netowrk traffic.
Any ideas on what is going on?
