I do have a different motherboard (P6T) but I didn't even try to get (20x200) on my C1. Instead I immediately dropped the CPU Ratio to 16 and bumped the BCLK to 200. Now I can get as high as 19x200, but when I do stability tests the core temps go over the 72°C that I feel comfortable with...
Maybe if I was running a water-cooling setup things would be different. As it is I'm stable at 3.6GHz on air (Zalman CNPS9900), and I'm happy with that result. In fact I might drop it to 3.2GHz just because that will allow it to run that much cooler. But I want the BCLK at 200! Since I paid for memory that meets that spec.
For the record I use a program named OCCT for my stability testing. It is basically a front end for Linpack, afaik. But I like it because it allows me to monitor my individual core temps, and it can also test GPU and memory.
