    So I recently purchased an Asus 1201N and it comes with the 330 dual core atom CPU, the Intel specs say that it supports Speedstep (ESS/EIST) but when I run everest it claims it isn't supported. Also CPU-Z will only display the max speed and multiplier even at idle (1.6GHZ and 12x). From what I have read CPU-Z should display the current speed, so if Speedstep is working correctly I should see it change in CPU-Z. Here is a screenshot, the reason I am concerned is that I have idle temps of around 50C wish i think is way to high even for a dual core Atom at idle.
    I would appreciate any input, did Asus disable it, am I not doing something correct or is there something else.

    It looks like it does not support advanced speed-step , I had a nettop with an Atom 230, a single core version of the 330 and it did not support advanced speedstep , but that was a desktop replacement , I am supprised a notebook does not have a advanced speedstep cpu to save power.

    You do have the befit of 64bit support and maybe why they used the 330 as normal atoms have 32bit only, but no speedstep would be a deal breaker from me.

    EDIT : you could try undervolting to save a bit of power.

    Yeah, RMClock should let you set the multipliers yourself.

    Well, Asus did include Super Hybrid Engine Utility program to counter that.

    I didn't think RM Clock worked with Atoms? Also I have tried using the super hybrid engine, I dont know what the difference between the 3 modes are, only thing I did notice is that on the super performance it OCed the processor by upping the FSB to 136Mhz, both the others stayed at 133Mhz (1.6Ghz). Tinderbox, you are right the N330 is a desktop CPU primarily so maybe that is why, tho I thought all atoms had speedstep. Does it have basic Speedstep? I noticed Everest said the multipliers were 6x -12x (see screenshot) that would imply that it did support at least a basic speedstep, maybe it only works for 6x when idle and 12x when under load, and if that is the case how come I can never get it to run at 6x. Would it have anything to do with the Enhanced Halt State being disabled? My big concern is both the idle temps since it seems that this thing runs at 1.6Ghz all the time and battery life, I am rarely at full CPU usage so the lack of speedstep will make a big difference in battery life, or so I would imagine even with the lower power atom.

    Intel atom does have speed step. Using crystalcpuid, you can undervolt the processor. My single core atom acer aspire one idles at nearly 60 degrees and may exeed 75 in rare cases under load. You have nothing to fear.

    Thanks Jack, I will check crystalcpuid. But I believe the desktop Atoms dont have Speedstep, i.e. the N230 and N330. Just the ones that you normally find in netbooks do, tho the 1201N doesn't since it has a desktop CPU despite being a netbook.

    I see that now, when I first posted I assumed all atoms did speedstep, rather than just the mobile ones. I guess the only think that confuses me is that everest says 6x-12x for the multipliers and the it has enhanced halt state so I was thinking/hoping that the 6x would be for the halt state (i.e. when idle) and 12x for everything else, but it seems Asus has disabled halt state.
    @ Jack. I tried crystalcpuid, but I think the voltage/multiplier changes rely on the processor supporting speedstep and my particular atom doesn't support that.
