i havnt seen this EIST option, is it short for a longer term ? i have an asus p8z68 v pro gen3
i think i noticed that in the advanced power setting the minimum cpu state is set to 5% and the multiplyer drops when all cores are around or below that figure, so myabe if i punch it up to 10 or 15 it wont jump around so much, in general is it healthy for the cpu to go up and down like that so much, i would think its better if its more stable.
would it be better to use an offset vcore?
The chip is designed to change frequencies like that, so it certainly won't hurt anything. EIST stands for Enhanced Intel Speedstep Technology, but it is normally listed as something with EIST in it in the BIOS - can't remember off-hand what Asus calls it.
If you want the votlage to drop when idle, along with the frequency, then you'll need to set up an offset voltage. It is easy to do - simplest method is to put in an offset of +0.005 and then load up Prime95 or IBT and check what the Vcore is in CPU-z. Then you just need to adjust the offset to make that Vcore match what you had set before. So if +0.005 gives you a voltage of 1.310 under load, you'd just change your offset to +0.015 instead and you'll be back to where you were. The other option, at 4.5, is to just run with an Auto Vcore - it'll probably end up being a little higher than your fixed voltage (so maybe 1.35 at 4.5) but it is easy and safe.
