I have 2 kits - a 2 x 1 gig and a 2 x 512 gig for 3 gigs in the Vista Home Prem. I have one of the new Gigabyte P35 boards where the memory voltage is a mystery. I'm assuming it's default is 1.8v, at least that's what I've read. So, I tested both kits at what I think is 2.0v and got errors in both kits. I'm now testing at 2.2v which is what the memory should be. The problem is the motherboard isn't clear on what the default voltage is. Anyone else out there have one of these boards or issues with this memory? Frustrated in Charlotte.
