I've got everything working perfectly on my Snow Leopard install, but I can't find a program that'll monitor my CPU clock speed/voltage/temps to make sure Speed Step is working or that OSX86 isn't making my CPU hotter than its supposed to.

My specs are:
Q8200
Gigabyte EP45-UD3LR
4GB
9600GSO

Everything works fine, but I'm worried I might be slowly killing my machine by using Snow Leopard.

I can monitor my temps with iStats now...

However, is there a way to check the clock speed with iStats, and possibly the voltage?

Author Update #2 @stevojd 2009-11-21

^ That's what I used to get the iStat temps, thank you.

My temps are a little high, but I guess I'll live. Do you guys have Speed Step enabled?

Author Update #3 @stevojd 2009-11-21

OOoh... Speed Step works perfect now!

I can't thank you enough! I can only use this inside of 32-bit SL though, correct? It doesn't matter to me, I've never even tried booting into 64-bit mode.

Field Note #1 @Imkantus 2009-11-21

You can also use latest fakesmc version 2.5 from netkas blog...
http://netkas.org/?p=338 ↗

It enables the missing devices, needed to read CPU temps using iStat and stuff like that.

Field Note #2 @mormegil 2009-11-21

I've C1E enabled and judging by the temps, they seem to work. The same temps I'm seeing in Windows.
