    Default booting in overclocked mode not possible

    Hi,

    i over clocked my pc to from 3.0 to 3.64 Ghz and it is stable under prime 3 hrs. I can play games well, but every morning i start my pc for the first time, it reboots 3 times and boots with standard settings. Then i restart from windows and go to the bios, set it to 3.64Ghz and it boots normally without continuous reboot.

    Board is a EP45DS3, Intel E8400, 2Gb OCZ PC6400 4-4-4-15@2.1V Ati crossfire edition. Bios Version F4


    What can be done to solve my problem?

    Also if Windows did not shutdown correctly, the BIOS on next time you turn on the computer will behave exactly that way.

    Default Re: booting in overclocked mode not possible

    Ok, I would add this first >>>
    Advanced Clock Control [Press Enter]
    CPU Clock Drive...........................: <<< 800
    PCI Express Clock Drive.................: <<< 900

    Then here is likely for sure your Main problem >>>
    Performance Enhance...................: Turbo <<< Set to Standard

    I would also make the following changes >>>
    (G)MCH Frequency Latch...............: 333 <<< Change to 400

    Command Rate (CMD) ....................: 0 <<< Set to 2

    You should also disable these as well or your overclock is likely to always give you issues or make you set far more then the needed voltages >>>

    CPU Enhanced Halt (C1E)................: [enabled] <<< Disabled
    C2/C2E State Support....................: [enabled] <<< Disabled
    x C4/C4E State Support..................: [enabled] <<< Disabled
    CPU EIST Function.........................: [enabled] <<< Disabled

    The rest looks good though if you do not want to take the time to tweak you ram to it's best. The performance setting is likley the main cause of you booting failure as I said above

    Hi,

    these two were already set.
    CPU Clock Drive...........................: <<< 800
    PCI Express Clock Drive.................: <<< 900

    changing only this:
    Performance Enhance...................: Turbo <<< Set to Standard
    didn't solve my problem.

    only after i changed these two additionally:
    (G)MCH Frequency Latch...............: 333 <<< Change to 400

    Command Rate (CMD) ....................: 0 <<< Set to 2

    it worked.

    Cmd was set to auto before and the value was shown as zero. Now I set it manually to 2.

    Another question: What does mch latch do exactly? i thought since i have a fsb1333 wolfdale it is ok to set it to 333mhz. Or does the overclocking need the change to 400mhz setting?

    That strap should be set to 400 because you are overclocked past 400 FSB.

    Yeah you have a 333 FSB CPU but you are using it at 405 FSB. You just past the 400 Strap so you want to use 400 FSB Strap

    Adjusting your FSB strap up and down will provide more memory speed options on the newer intel chipset boards and will also provide you with a faster speed at a given strap. The higher the strap the faster your computer will run up to matching FSB of that strap. So a 400 FSB strap kicks in at 400 FSB and will not balance out until much higher say 480 or so
    I can link you to some in depth reading about FSB Straps and how they are used if you like, Actually here is the link >>>>

    Let me first say to Lsdmeasap that your Sticky's and posts on this board are fantastic m8. Since putting a fan on the northbridge I haven't looked back. However......

    I have a EP45-DS3L (F8) with specs and a problem really similar to Tweakdown (which is why I decided to post here). My annoyance is when starting up (from cold only) is that it takes 2 trys to boot up, on the first try the fans spin up everything is looking good then before anything displays it powers down for 5 seconds, then it tries again and no problem, straight to windows.

    I to am overclocking my e8400 to the tune of 400x9, only I have 4gb of G.SKill PC8000 5-5-5-15@ 2.1v

    I followed your suggestions to Tweakdown.
    CPU Clock Drive...........................: <<< 800
    PCI Express Clock Drive.................: <<< 900
    Performance Enhance...................: Standard
    (G)MCH Frequency Latch...............: 400

    However after changing Command rate to 2 (and saving as a different profile in the bios, another outstanding idea of yours) the m/b went into a cycle of power ups and downs (I had to laugh), so I had to reset the CMOS. Got back in and reloaded my last good set. Which is how I found out about command rate being the culprit.

    I'll post my settings as it makes life alot easier.

    Would appreciate anyone's thoughts on way it won't come up the first time from cold. There are no USB devices plugged in btw.
    Have just discovered if I go manual on the mem timings I get the perpetual reboot.
    Thanks very much.

    This is 2x2GB right?

    Channel A
    Static tRead Value.........................:11 <<<< ? See below

    Channel B
    Static tRead Value.........................:11 14

    Did you miss this one or are they both actually set to 14?

    I would suggest you try a bit more MCH voltage for now. As for the rest of your timings, AUTO is no help at all really, especially with 4GB. Just because manually entering them fails do not give up, it just means they were not correct.

    Can you download this and post me a screenshot of it running so I can see what Auto is actually giving you to use in windows? >>>
    Tweakers.fr MemSet 3.5

    *NOTE* This is a "LIVE" edit Ram timings app, be careful if you do change anything, and do not use the save button. It is very helpful if you want to test something out a setting at a time in windows but CAN crash and freeze your PC for sure.

    Command rate should be 2, 1 will not work on most all intel boards, and especially is not going to work with 4GB either.

    So your AUTO for command was likely already 2, manually changing it to 2 would have no effect so you must have made other changes at the same time. Or AUTO was wrong on something else already.

    Auto is for starting your PC when you first buy it so that it possibly works with most any hardware config, best to not be used if possible

    Hello,

    i just tried your linked tool for fun. Now i wonder why tRef is set that high?

    3159?? is this normal?
