Clock Multiplier Changing

[allosunshine]

I cleared the CMOS on my mobo last night and I've just checked CPU-Z and for some reason the Clock Multiplier keeps changing from 6-9 but I know it is set to 9 in the BIOS.
Any suggestion to why this is happening??

Disable EIST TM2 and C1E in advanced BIOS features if its the DS3 in your sig.

It's Intel Speed Step technology, throttles the CPU when idle to lower power usage.

Is it best to leave it be and let it do its own thing or should I disable the settings mentioned and have it running at x9 multiplier???
Cheers.

what is does is when your computer isn't being used a lot, it droppes the multiplier, causing less voltage usuage, lower temps.

but as soon as its needed again it jumps back up.

Just out of curiosity (don't own a C2D), but does this mess up overclocks like the Athlon 64 equivalent used to?

the clock speed will drop with the multi,

if you are running 400 fsb

10x = 4000mhz
9x = 3600mhz
8x = 3200mhz
7x = 2800mhz

fsb stays the same but the clock speed changes

Don't find it of much use on desktop pcs tbh, doubt its a significant saving on power for significant savings on the electric bill

heat is less so you can turn down the fans, and then have less noise

Personally I left it enabled because I couldn't think of a valid reason to turn it off

I honestly haven't seen a drastic difference on an idle temp between an EIST controlled cpu vs one going at full bore.

me too i've never really noticed it,

I have found sometimes that is doesn't change back from the low multi.
