I've owned Patriot memory in the past with my 775 build. I am currently building a box for my friend and am evaluating the Patriot memory offerings. Since they've built their reputation up, they are certainly in the front-running to support this build.
I've run Patriot RAM on my system for years. When 2 years ago my ram starting having errors, I quickly and easily got a new replacement. I'm pleased with Patriot performance, but even more pleased with their great warranty and service.
