Ballout and Package Information

The (G)MCH ballout supports platforms using DDR2 and DDR system memory. The (G)MCH’s

system memory interface ballout differs between DDR2 and DDR modes.

Note:

The DDR and DDR2 signals are multiplexed so that they are supported on the same package.

14.1

DDR2 Ballout

Figure 14-1, Figure 14-2, and Figure 14-3 show the 82915G GMCH ballout for platforms using

DDR2 system memory, as viewed from the top side of the package. Figure 14-1 shows columns

1–12; Figure 14-2 shows columns 13–24; Figure 14-3 shows columns 25–35.

The complete DDR2 ballout for the 82915G/82915GV/82910GL GMCH and 82915P MCH are

listed in Table 14-1 and Table 14-2. Table 14-1 is sorted by ball number. Table 14-2 is sorted

alphabetically by signal name based on the signal names of the 82915G GMCH. Note that the

first table has more entries than the second table. The second table does not include unpopulated

balls whereas the first table does.

Note:

Balls that are listed as RSV are Reserved. Board traces should Not be routed to these balls.

Note:

Balls that are listed as NC are No Connects. Board traces to these balls are permitted as specified.
