D0 Stepping will be introduced to both Pentium D and Celeron. As 65nm process is now in mature, the specification is upgraded from FMB 05A to FMB06, with 65W TDP as a maximum. Since most of the Intel based main board follows the FMB 05B specification, there is no necessary change to the design.

D0 Stepping will be introduced to both Pentium D and Celeron. As 65nm process is now in mature, the power specification is upgraded from FMB 05A to FMB06, with 65W TDP as a maximum.

The D0 Stepping processor includes Pentium 4 631(3.0GHz/2MB L2/800MHz FSB), Pentium 4 641(3.2GHz/2MB L2/800MHz FSB), Pentium 4 651(3.4GHz/2MB L2/800MHz FSB), Pentium 4 661(3.6GHz/2MB L2/800MHz FSB), Celeron D 356(3.46Ghz/512KB L2/533MHz FSB), and Celeron D 360(3.46Ghz/512KB L2/533MHz FSB). Besides D0 Stepping Pentium 4 and Celeron, the whole family of Intel Core 2 Duo is specified FMB 06 by its low 65W TDP. However, Intel Core 2 Extreme X6800 is an exception to the new release with FMB 05A just because it’s a 75W TDP product.

There are FMB 05A and FMB 05B specifications for the power module in Intel based main board; FMB 05A and FMB 05B are specified for a maximum of 95W and 130W TDP respectively. The TDP will be lowered to 65W for Intel Core 2 Duo processors; therefore a new specification FMB 06 is added for those 65W TDP products. Since most of the Intel based main board follows the FMB 05B specification, no necessary change is subject to the design.
