    I don't recall I have seen "L" board with 500FSB.
    Other users with boards that are capable of 500FSB often choose to use less for 24/7 use.
    Not a bad deal at all, and you can still try CPU Ratio 8.5 or 9 and you get great performance for the $$$. At least that's how I look at it.

    You`re right.....do you think i should improve the RAM settings ( not for 500 but for the 450 FSB i have now ) ? or just leave it like this ? if i want to make an upgrade for my cpu what motherboard should i buy ?

    Sure try to set lowest Static tRead possible for both channels.
    Either try to lower timings 5-6-6-18 to 5-5-5-15 with current DDR-900, you can try the same timings with 2.40B multiplier for DDR-1080.
    Then you can try lower tRFC if you find it give better performance.

    The pink color for DRAM Voltage is just to alert you you should know what you are doing, if ram specs is 2.1v then no worries. To make sure check the actual applied voltage in PC Health Status.

    I'd save the money for a new generation CPU/motherboard in the future. I realy don't think it's worth upgrading the motherboard.

    Here are some results ( thank you very much for the guidance and support !!!!! ) TRD static cant go below 9 ; ram set to 5-5-5-15 (tryed 4-5-5-15 - doesnt boot).....multiplier 2.40B doesnt boot at all ......i decided that 450x8.5 is enough ( as i said im interested in high FSB rather than high frequency) .....stable 39 celsius and also IBT ok....

    2.40B ws with 6-6-6-18 and Static tRead 10-11? If you manage it compare performance to current settings, performance not numbers in BIOS is what matters.
    I use MaxxMEM² - PreView for memory benchmark, Everest has one built in too.

    Just remember ICH/IO is below default, in case you run into problems with disks or USB devices it might be it.

    EDIT: let orthos blend run 8-12 hours to make everything is ok with the settings.

    Here`s what i have with current settings ( btw the multiplier is 2.00D ; theyre all D > 2.33D etc etc....only if i set it on auto then it changes to B).......i set the ICH core voltage to normal ( you were right -again - in games i was having some lag issues from mouse which is usb ...should i set the voltage higher to be even better ?)....latency seems to be my ram problem.....ideas?

    Set what, MCH Frequency Latch? You can leave it auto.
    Try 2.00B also see if it enable you to lower Static tRead or give better performance.

    I don't realy know, mouse lag, system stutter may be the result of unstable memory settings too. Not below default anyway.

    Unless you can use CAS 4, or DDR-1080, you can try to lower tRFC to 52 or even less. This will require extended stability test, 12+ hours Orthos/Prime95 blend torture.
