It seems like you might be a little confused about the ram.
Yes, with no problem, the gigabyte ds3 will run DDR2-800 ram that requires all the way up to 2.4v or so. The first mistake was looking at intel's specifications. You need to look at gigabyte's specifications for the board.
Gigabyte is not known for any general compatibility issues with ram, so any ram should work just fine in there. The only problem, slightest chance of possibility, is that you would be required to use a different stick of ram to boot up the system so you can select the correct voltage in the bios for your high performance ram. but i think this isn't really an issue and with most ram it should boot just fine.
The ram in the search i link
here to newegg is the fastest ddr2-800 ram, or the correct way to say it would be the one with the tightest timings.
The ram that was linked to above looks like good ram. Although he said he can run at ddr2-800 with 3-3 timings i would never guarantee it although most likely it should run fine.
The price you pay for the tighter timings though is not representative of the performance gain you get, so any ddr2-800 with 4-4-4-12 timings will be fine.
