You're welcome.
EIST is bit 25 of eax register (here it is 0), and EIST is bit 16 (here it is 1).
If you're running XP, you can go in control panel -> power option and set the scheme to Home/Office desktop. It will disable EIST transitions (but EIST bit will keep being set).
You can use a MSR editor to change the value of bit 16 (CrystalCPUID includes one). In your case, you have to set it to :
Code:
MSR 0x000001A0 edx = 0x00000040 eax = 0x60962489
BIOS could also do that, look for something that includes "speedstep" word.
