    i'm currently using CPUgenie 1.3. Its a great software but it crashes sometimes on start up but other than that it does its job.. problem is that there is only a 30 day trial? Is there anyway to extend the trial? Also can someone recommend me a similar software? i know that Crystal CPUID is one but i don't know how to use it. Is there a guide on how to use it? Also are there any other undervolting softwares?

    Thanks.

    Problem is T9400 has half multipliers (9.5X) and to make RM clock to recognise that i need to do registary changes and i don't want to do that. Somemore that program is obsolete as it doesn't get updated.

    Ah fairy nuff. In that case I think Crystal Cpuid is your best and possibly only free bet. I haven't used it yet however so can't give adice on how it works. Might give it a try though rmclock won't let me undervolt below 1.0125V on my Q9650 I want sub 1V for battery operation :)

    Notebook Hardware Control allows for undervolting the CPU and it is easy to use; unfortunately it also comes with a lot of other power management features. It's not as light-weight.

    A new, free, lightweight, easy-to-use undervolting program? Afraid not.

    I'm using crystal CPUID... in the 3 voltages , Max Middle and Min , which multiplier to use? I know that max is 9.5x and min is 6.0x... so what about middle?

    middle one doesnt rly matter since your cpu is mostly at either high or low

    just set it to a value about at the middle

    Make sure you're at max multiplier (let your CPU do some work, watch a movie or run some CPU_intensive software), then go to Function-> Intel Enhanced Speedstep Control, click 'Enable Change Voltage' (again, make sure the multiplier is 9.5x) and choose whatever voltage you like, I'm at 1.20V on a P7350 (from 1.25V).

    And yes, undervolting only really matters for the max multiplier. The CPU is rarely at the middle multiplier, and at the min multiplier, the voltage is lower anyway (so is the clock speed), and not much heat is generated.

    The problem with CrystalCPUID is that it is casuing massive voltage changes when idle.. i don't have any of those problems with CPUGenie... so how? also in CPUgenie i have the option to change the super LM Voltage.. looks like i'm stuck to use CPUgenie some way or other.
