Due to the chipset or do you expect no suitable bios here also.
My phenom failed prime95 at 210x11 last night, so switched back to my old m2a-vm and voila the system requires less power in idle (no CnQ) now.
When Asus gave me the email address to the engineering department they also stated they don't support overclocking, so in a word yes I don't expect a suitable bios.
