What does the CPU-Z SPD tab display? Is there a JEDEC 400 MHz entry? Did you try setting the memory clock to 400 MHz?

Your PC should definitely detect PC6400. Are those modules certified to work at 800 MHz in that system? You answered "yes cpuid says the correct", but what are the JEDEC values at 400 MHz?
