My i950 is mobo limited. Boots up 222 bclk with normal volts/settings no problem. 223 is no go. Then raise pcie, ioh, vtt, etc and 229.x boots up fine. Raising pcie above 103.3 or bclk above 229.x to 230 it freezes. I think if I could raise pcie higher could do more.

But like eva said, limit can be either. I think if your cpu makes it to 222, it is probably mobo holding u back, since most mobo on normal settings take a reasonable cpu to that point. If cpu is crapping out a lot earlier may be more of cpu issue. But I have seen most D0 get to much higher bclk than C0's.
Don't think it's my chip. I have had an i7 920 C0, i7 940 plus my current i7 920 D0. I'm yet to see my R2E even post above 200Mhz. Just ordered a Classified, so I'll find out soon I guess.
