So I have the sk8v and the opteron 280. As I understand this mobo does not have pci agp lock. Running it at 250ht for 3.0ghz with 3:2 memory divider for 200mhz everything works fine except for onboard sata. The stock htt is 800 mhz I can run it at 750 or 1000 both work fine. I use a sata pci card for storage. Is this safe for the agp card? I'm running the x1950 pro. Also voltage for the opteron whats the safe limit? I'm currently running at 1.525 and it fluctuates to 1.536. I've pushed it as far as 3.138 ghz at 260ht.
