I've tried enabling/disabling in all possible combinations:
USB Legacy support
USB 2.0 support
USB emulation type (Auto/HDD)
Hyperthreading support
No-Execute Memory Protect
Onboard SATA controller (Auto/Enhanced/Disabled)
ACPI
Onboard video 8MB/1MB
Also With and without an Adaptec 2820SA and Intel 1000/MT
Also, using a basic PCI VGA card instead of the onboard didn't change anything.
How much memory do you have in the P8SCT.
It should work as I have seen other customers using that motherboard.
Did you try turning off any power management features in the Motherboard BIOS
Try booting the system with the module and after POST hit the "Escape" key to enter a basic menu then select "Rescue mode". If it boots from this to the Console then go to CRT + ALT + T and select "Boot options" then select "Boot parameters" and disable all and reboot normally to see if this works.
