I'm experiecing some major problem with this board. I frequently get lock ups (around every 5-10 minutes), I can't boot again unless i wait around 30 minutes! Here is my setup: AMD64 3800+ 2x1GB Kingston Value Select Pioner DVD-RW 2x250GB Seagate (RAID0) 1x160GB Seagate Geforce 6600 256mb RAM As a temperary work around I'm now running the SATA drives of the SiL 3114 chip. That seems to improve the stability but it still locks around every 1h And this way i can't use the 160GB since the Sil Chip doesn't see it, it only sees the RAID Extra Info: Problems started acoring once the Chip fan died, I replaced it and now the temp are around 35°C Idle, in stead of around 37°C Idle. The fan died around the same time i switch to sata drives. I think that the NB Chip is getting to hot might be the problem, but 35°C seems okay to me.
