    I have a Core Duo L2400 which is the low voltage version. I used RMClock but I only see 6x @ 0.950V to be the lowest settings. I've also used RMClock on a REGULAR T2400 and the lowest is still 6x @ 0.950V.

    Where is the area that makes the L2400 low voltage? Does it have it set in hardware that you can't view on programs?

    Thanks!!

    The low voltage is at the max multiplier. Check the voltage between the T and the L at max frequencies. The L series will have much lower voltage although in some cases the T can also be undervolted to the same range as the L series voltage. The lowest multipliers tend to be the same in most LV processors.

    I had both a X60s and X60. The T2400 was 11x @ 1.150 and the L2400 was 10x @ 0.988v. Do you know how much of a difference in battery life your talking about by using these voltage numbers?

    Whats weird though is that the X60 is like a jet engine compared to the X60s. Both underclocked and the X60s is whisper silent.

    Those voltages(being standard) are pretty good themselves. Take a look at the technical paper for the Core Duo. It should list the TDP's at different power states...(page 80)
    ftp://download.intel.com/design/mobile/datashts/30922102.pdf

    The difference in fan speeds might be due to the specified TDP's. Manufacturers design the cooling system based on this number which for the T series(31W) is twice as much as the L series(~15W). Even though they might be similar the fan controls on the X60s might be different than that on the regular X60.
