SSDT2.dsl:
Name (CFGD, 0x780783F2)
// dunno if the run-time SSDT's change this or not, but lets assume
// that they don't until we see them...
SSDT1.dsl:
Method (_PSS, 0, NotSerialized)
{
If (LEqual (And (CFGD, 0x00060000), 0x00020000))
{
Return (SPSS)
}
If (LEqual (And (CFGD, 0x00060000), 0x00040000))
{
Return (NPSS)
}
If (LOr (And (CFGD, 0x4000), And (CFGD, 0x00010000)))
{
Return (NPSS)
// we should come here, based on CFGD value above
}
Return (SPSS)
}
...
but in either case, the BIOS really is reporting 44 GHz and 29 GHz:
Name (SPSS, Package (0x02)
{
Package (0x06)
{
0x0000AE45, // 44613 MHz
0x000157C0,
0x000000A0, // latency = 160usec, consistent with I/O?
0x0000000A,
0x00000036, // ctl
0x00000000
},
Package (0x06)
{
0x0000742E, // 29742 MHz
0x0000F230,
0x000000A0, // latency = 160usec, consistent with I/O?
0x0000000A,
0x00000136, // ctl
0x00000001
}
})
Name (NPSS, Package (0x02)
{
Package (0x06)
{
0x0000AE45, // 44613 MHz
0x000157C0,
0x0000000A, // latency = 10usec -- consistent with MSR
0x0000000A,
0x00000923, // ctl
0x00000923
},
Package (0x06)
{
0x0000742E, // 29742 MHz
0x0000F230,
0x0000000A, -- latency = 10usec -- consistent with MSR
0x0000000A,
0x0000061B, // ctl
0x0000061B
}
})
How did you verify that scaling is working on XP?
Can you verify that the BIOS for this board supports this processor?
