Hello.
Several days ago, I made a question through the official support channel at Gigabyte's site about the DDR2 voltages. They just replied me today, and here it is:

Dear Sir,
Thank you for supporting GIGABYTE products and contacting GBT Tech Support. As to the problem you mentioned, we follow the regulation which release by the JEDEC organization for the hardware standard. (http://www.jedec.org/). All the hardware have to follow the regulation to become standard. So far, they have the regulation of DDR2 memory modules up to DDR667 with 1.8V design.
Because there are too many kinds of memory modules available in the retail market, it is very difficult to test all of the modules with our MB products. Meanwhile, if possible, we also recommend you choosing the modules with famous brand and test the modules with your system before you buy them to avoid H/W compatibility issue
Therefore, the modules like DDR2 800 currently available in the market are not concerned as standard modules. DDR2 800 modules are still on the way to meet the regulation. Most of the venders try to add voltage to overspec the product in order to reach DDR2 800. Therefore, we cannot guarantee the product overspec can work on the M/B since it is not standard. If you want to use DDR2 800 memory modules, we will suggest you to purchase it after the rule is done by Jedec and release the standard design for all memory manufacture to follow. Sorry for the inconvenience that has encountered.
Best Regards,
GIGABYTE TECHNOLOGY
