When I install two memory sticks kingston and a corsair both pc3200 rated at 400mhz bios shows it running at 333mhz only. When I install each one individually they both run at 400mhz. Does anyone have any information on what I should or can do to fix the problem. I have already tried installing it according to the motherboard (MSI) configurations with no luck. If anyone has any information on this I would really appreciate it.
