The cB1 stepping is logically equivalent to the C2-step, but on a different manufacturing process. The mcB1 step is logically equivalent to the cB1 step (except it does not support DP, APIC or FRC). The mcB1, mA1, mA4 and mcC0-steps also use Intel's Voltage Reduction Technology and are available in the TCP and/or SPGA package, primarily to support mobile applications. The mxA3 is logically equivalent to the xA3 stepping (except it does not support DP or APIC).
This CPU has reduced minimum valid timings on some output pins.
The part is not tested to support 82498/82493 and 82497/82492 cache timings.
