I found software that used
[bash]MSR_CORE_THREAD_COUNT MSR_PMG_CST_CONFIG_CONTROL [/bash]
and also in binary file I see addresses 0x35, 0xce, 0xfc, 0xaa, 0x1ac, 0x1ad.
I think they a model specific but why there is no decription in any Intel documentation including 253668.pdf and 253669.pdf?
Is Intel going to publish more information about MSR registers?
