Ballistix 667 2gb probs

What Gigabyte MB do you have, model number. Some micro Mb's do not provide voltage adjustment for RAM due to lesser voltage regulators than full ATX MB's. List your system specs including MB model number.

Well, your board may have been made by Gigabyte for the system Mfg., but Gigabyte would call their retail product differently than a GA-8TRC410M-NF. Gigabyte would not list your MB on their site. It's the system Mfg.'s responsibility to provide updates for THEIR system's MB. That's my take. Have you treid the system Mfg. page for any updates for your MB? Is your MB a micro board? Does the board have onboard graphics. Micro boards usually have inferior voltage reegulators and many (not all) provide little BIOS options where system tweaking is concerned.

As far as the Crucial DIMMS you are attempting to use, try entering your system into the Crucial Advisory tool to find memory that is guaranted to work with your system.

You might try sending Crucial online support an email and ask what they have available for your system. Crucial also has an online chat support available.
