You can do in grub2
wrmsr 0x199 0x1128
before OS loading.

Added it to grub2.
However no miracle happened.
Windows boot time was so long.
Cpu is 598Mhz.
I executed a command
rdmsr 0x199
and saw output
Read MSR 0x199 : High 32bit(EDX) = 0x0000000000000000, Low 32bit(EAX) = 0x0000000000000612
63 56 55 48 47 40 39 32 31 24 23 16 15 8 7 0
00000000-00000000-00000000-00000000-00000000-00000000-00000110-00010010
Ps. Debian changed cpu speed after your trick.
/proc/cpuingo gives 1695Mhz
anyway many thanks man

May I ask you? What way can I patch MBR or boot sector?
If you asked then you can't do it.

I was misled you, I've decided your words about patching MBR or boot sector could solve improper CPU speed in Windows.
You need to add new code to MBR:
xor edx,edx
mov eax, 1128h
mov ecx, 199h
wrmsr

Do I understand right - this code always set cpu to a maximum speed?
