You'll want to find the timings for your specific model of RAM through the manufacturer. Go to their website and find the specs, then set the timings, speed, and voltage to what the manufacturer says. I'd be more specific, but I don't know my way around Patriot's site and I don't know exactly what you have. CPU-Z will display the model number for you if you don't have the packaging.
1T vs 2T is the number of instructions per clock. Generally, 1T is better, but not all RAM is designed to run at 1T, so you'll have to go with what your manufacturer specifies.
