3.3.4 Thermal Test Vehicle Information
3.3.4.1 Introduction
The Pentium 4 processor with 512-KB L2 cache on 0.13 micron process Thermal Test Vehicle
(TTV) is a FC-PGA2 package assembled with a thermal test die. The TTV is designed for use in
platforms targeted for the Pentium 4 processor with 512-KB L2 cache on 0.13 micron process.
The Pentium 4 processor TTVs are in limited supply; contact your local Intel field office for
eligibility and availability.
Cooling solution performance should be defined using the TTV only. Not only does the TTV
provide a well-characterized tool suitable for thermal testing, it also allows simulating processor
thermal targets before real processors are available. The correction factor of the TTV to real
processors, given in Section 3.3.4.5, Table 2, is then used to define the performance of the
solution on real processors.
The part number for the TTV is A47244-01. There were two builds of TTV’s. The TTV will
either have a, “ITVN1 THERM SAMP” marking or a handwritten part code “QEL0” on the
topside of the IHS. Samples of both markings are shown in Figure 11.
