All sockets (Pentium 4 and
Celeron) have the following mechanical maximum load limits which should not be exceeded during heatsink assembly, shipping conditions, or standard use. Load above those limits may crack the processor die and make it unusable. The limits are included in the table below.

Celerons, along with several of the
Willamette-series Pentium 4s. Socket 478 also supported the newer Prescott-based Celeron D processors (which were also one of the last CPUs made for the socket), and early Pentium 4 Extreme Edition processors with 2 MB of L3

While the Intel mobile CPUs are available in 478-pin packages, they in fact only operate in a range of slightly differing sockets such as
