Great clocks. What is the CB and CBB?

I've thought about trying my 2600k under LN2 but so many people were saying it didn't help.

Mine will load windows at X58 but only up to +/- 98 bclk so the overall speed is still shy of 5.7GHz. This is using a SS @ -45/-50C. Maybe colder will give mine a little more bclk?

Looking forward to more results.
