After reviewing Gigabyte's SiS 648-based 8SG667 motherboard about two weeks ago, we were very pleased to see how well Gigabyte implemented DDR400 support. We had no trouble running 3 sticks of CAS2 Corsair DDR400 memory in all 3 DIMM slots at aggressive timings. And of course, we saw some modest performance gains utilizing maxed DDR400.

It seems as if Gigabyte has done a similarly good job with the Gigabyte 7VAXP. Using an as of yet unreleased BIOS, the 7VAXP's prospects with DDR400 still aren't anything too exciting or stellar, but we can at least proclaim this time around that this memory type actually does work quite well with this motherboard. We'll take a look at this aspect of the 7VAXP in the coming pages.

Read on to see how Gigabyte has tweaked the KT400 chipset and how you will reap the benefits of their hard work…
