From the moment I changed the Performance level to 7/8 or 9, I got the C1 error and it wouldn't boot at all. This was also the case with every other setting I changed manually (1 at a time)

I changed the strap to 333/800 and had no booting problems anymore. I can change every timing manually without getting that C1 error.

I'm using the Ballistix PC8000 on my UT (bios 0214).
I loaded optimized bios settings and then went back and changed all my settings except dram timing. I was then able to boot at 333/667. I had tried flashing the bios and that wasn't the problem.
As you mentioned, I also think it has something to do with performance level. I can run at 8 - 9 but not 7. I had timings set at 5-5-5-5-15 and the rest Auto. Maybe one of us will narrow it down to exactly which setting is the problem. I'm going to work with the performance level when I get time and see if that's the issue.
