EIST in the CPU subsection of the BIOS is called Intel TM (Thermal Monitoring or something like that).
This can be set to 'disabled'.
When everybody calls it by its proper Intel name, but noone uses the Asus-Bios naming, no wonder
that there are misunderstandings.

Funny thing is, with my E8400, stepping e0, it doens't matter how often I set this (after first having
cleared my CMOS), I still end up with 'Auto' CPU Voltage (even when following Falkentyne's instructions
word for word). Plus, when I try to change the multiplier, the P5WDH will not POST: I have to clear CMOS
again to even be able to enter the Bios. All this on a revision 1.04G motherboard.
It's bloody annoying.
