Chapter 1
chapters also apply to the 82845GL/82845GV with the differences noted in this chapter. This
chapter describes the differences between the 82845G and 82845GL/82845GV components.
Figure 9-1
The information in this chapter applies to both the 82845GL and 82845GV components, unless
otherwise noted. Also, unless otherwise noted in this chapter, GMCH applies to both the 82845GL
and 82845GV components.
Processor System Bus (PSB) Frequency
82845GL: The 82845GL GMCH supports PSB frequency of 400 MHz (100 MHz bus clock) only.
References in the main body of this datasheet to a PSB frequency of 533 MHz are not applicable to
the 82845GL.
82845GV: The 82845GV GMCH supports Processor System Bus (PSB) frequencies of 400 MHz
(100 MHz bus clock) and 533 MHz (133 MHz bus clock). This is the same as the 82845G.
