Balanced Technology Extended
(BTX) Boxed Processor
Specifications
The Intel Pentium 4 processors will be offered as an Intel boxed processor. Intel boxed
processors are intended for system integrators who build systems from largely
standard components. The boxed Intel Pentium 4 processor will be supplied with a
cooling solution known as the Thermal Module Assembly (TMA). Each processor will be
supplied with one of the two available types of TMAs – Type I or Type II. This chapter
documents motherboard and system requirements for both the TMAs that will be
supplied with the boxed Pentium 4 processor in the 775-land package. This chapter is
particularly important for OEMs that manufacture motherboards for system integrators.

Note:
Unless otherwise noted, all figures in this chapter are dimensioned in millimeters and
inches [in brackets].
Note:
Drawings in this section reflect only the specifications on the Intel boxed processor
product. These dimensions should not be used as a generic keep-out zone for all
cooling solutions. It is the system designer's responsibility to consider their proprietary
cooling solution when designing to the required keep-out zone on their system
platforms and chassis. Refer to the appropriate processor Thermal and Mechanical
Design Guidelines (see
Figure 25.

the basic shape and size will remain the same.
