c1 seems related to n/b instability either ram voltage or timings off or not enough n/b voltage. each time i had it happen it would recover though
I have read quite a few posts now complaining of RAM/C1 errors etc coupled with my own experience of this board I would say 1:1 has problems running CL5.

CL4 on the other hand has never given me a C1 error & I have run 1140MHz + where as CL5 throws errors frequently & randomly @ at timings/speeds I know are good for 1200MHz +

I too had a P5K & could get my RAM running higher & tighter speeds on benching voltage. The only problem for me with the Asus was the vdimm needed to run tweaked/tight 24/7 stable over say 1100MHz CL5 was on or very close to maximum warranted voltage.

The DFI on the other hand will make higher RAM speed with much lower voltages however the interesting thing in all this is the P5K's bandwidth & latency was higher @ lower fsb than the DFI so what we are looking at IMO is a kind of trade off between speed/fsb & efficiency/work done due to latency.

My DFI will make very high RAM speed @ low voltage simply trading off performance for speed. I have been able to out perform my P5K in terms of RAM FSB at the expense of performance.

I cant really offer any opinion as to which board/way of doing things is best as I think the net effect is about the same just achieved in a different way. This different way of doing the same thing kind of makes me wonder if this DFI P35 is giving us a glimpse of the way the up coming X38 may offer its power. I believe from what I have seen & read, the X38 makes its power @ high FSB/MHz rather than tight timings eg CL6/8 DDR 1600-2000.

btw for an instant yesterday while i was trying to get past a c1 i swear the led said FU as a post code.lol i keep my camera ready after that...
I know I shouldn't laugh at someone struggling but bhhh he he FU that would be priceless if you caught that on camera.
