    Default GA-EP45-DS3L Help Overclocking Intel Quad Q9300

    Hi guys

    I need some serious help, I have some issues with my GA-EP45-DS3L and my Intel Quad Q9300, i'm overclocking from 2.5 to 3GHz and it works very stable when it first boots into the OS, I do what i have to do etc etc, but once I shutdown the computer or simply do a restart, system has problems booting from the BIOS and goes straight to the backup bios after a couple of times.

    I dont have all the BIOS setting with me since i'm at work, I can provide them later, but can anyone share with me stable settings for 3GHz overclock or 3.5GHz if possible?

    It is very inconvenient to have to go into the BIOS to reset the overclock settings the way they were, work on the PC for hours without crashing, and then go back to the same thing every time i shut down or restart.

    Any help would be greatly appreciated

    PS: Brand new build, RAM was fully tested individually with no problems.

    Can you list all your hardware please?

    You can save the BIOS settings to a profile by hitting F11 in the main screen and load those settings again with F12, this makes it a lot easier to try different settings.

    As for BIOS settings, it's easiest when you just post your current settings and we tell you what settings you should change then.
    You can also look around a bit, there are quite a few other people overlocking that CPU and the BIOS of the P45 boards are all nearly identical.

    Thanks nickel020

    I will post my bios settings and my hardware configuration in a couple of hours after i get home, thanks for the F11 tip.

    Thanks again!!!

    Try setting the system memory multiplier to 2.0D, you can always icnrease it agian alter on but first you should figure out whether it's the RAM or the CPU causing this.
    You should also increase VCore. Your value will be like 1.16V real in CPU-Z and that's probably not enough to keep the CPU going. Try bumping the VCore in BIOS to 1.30V, this will probably result in a real value of about 1.23V.

    I think you need much more vcore, and possibly a little more MCH Voltage (Maybe 1.22-1.24).

    And I have to warn you now, leaving these in auto will kill your CPU Very fast overclocking >>>
    CPU Termination…..... 1.200V*.......: Auto << Set 1.2-1.34 (Keep at least .1 under vcore)
    CPU PLL…………………....1.500V*.......: Auto << Set 1.5-1.58

    Other then that, I do not see any Major issues. Setting those and raising your vcore may fix you right up. However, until then I would advise you raise these a bit until you get squared ways >>>

    tRFC........................................... 54-56

    nickel020 and Lsdmeasap, thank you so much, i will go ahead and try to tweak the vcore and the MCH voltage.

    Thanks for the warning about the Auto seettings on CPU Termination and PLL Lsdmeasap, i have had those set on auto for a while.

    Also, i have seen on my research on overclocking this CPU, most people recomend to disable this function "CPU Enhanced Halt (C1E)................: [Disable]" so i when ahead and did, just wanted your input on that.

    I will report the results later tonight when i get home, thanks again for your help, this is my first time overclocking and i build this PC for that purpose, i'm getting a better understanding on it thanks to you guys.

    Allan.

    Anytime man! Hope your CPU is ok, it likely is fine if you have not noticed anything funky yet.

    Ya, if you want to overclock and find stability the easiest you will have to disable C1E and EIST

    Good luck, and keep us posted!

    Ok, it does not matter what i do, it keeps doing the same thing, i will go step by step in regards to the symptoms, mind you the BIOS is already set with the overclocking settings that i will display below so you guys can revise them with the updates i made;


    1. I turn on the PC, the POST screen comes up.
    2. When it performs the Memory Test part there is a time delay when it gets to it, it displays "Memory T" (The letter "T" for test is not displayed for a few seconds and them it completes the message with the amount of memory and the "OK", after that it restarts the computer again for some odd reason, but this time it reverts back to the default BIOS settings.
    3. When that happens, i get into the BIOS, i select the option "MB Intelligent Tweaker (M.I.T.)", it displays a message telling me that there was an error due to overclocking, i press enter and i leave all the settings as they were when i last saved them.
    4. I leave all the overclocking settings set, get out, save and it restarts.
    5. This time the POST is completed without any complains and my OS loads without any problems at all with no errors or crashing any applications.


    I tested my Ram once again individually and both together with MemTestx86, it showed no errors!,

    There is something missing, something is triggering the BIOS to reset, but when I set the settings the same as before it works!.

    Any more ideas of what it could be causing this?? i dont want to give up on this, correct me if I'm wrong but since the system restarts itself when the Memory Test is performed when I first turn on the computer, that tells me it that the problem is more than likely the ram settings.

    Thanks in advance again!!!

    Im just posting my differences to your settings.Components are a bit different of course
    They work ok for me,Nothing is in the danger zone as far as I can determine and it has passed all tests at these settings.Well actually its done 24 hr tests at either 490 or 500fsb,more on the 500 as 3.5G was my aim.It doesnt hang or fail to reboot.

    Yes I can get the 2:00D and 2:66D multiplier to work ,but it needs a lot of tweaking of settings.The exact settings above would underclock your memory a bit.
    My gskill wont go above1000 stable.Best I could manage was 1066 with 2.66D multiplier but had to use standard performance and all sorts of tweaking with settings .
    I dont see any reason why above settings shouldnt work for u for 24/7 use and u could try different settings in the meantime.
    Your memory is better, and hey that extra .5 multiplier would help too.
    Your cooler isnt standard otherwise I wouldnt have posted these,cpu might get too hot with intel one.
    500mhz fsb is very similar just needs near 2.2 v for memory so i dont run it for now.

    Before trying these settings,if you are going to:
    Save the ones that are working..or at least that you think are working .
    Then load the optimum defaults then press f10 and hit enter.
    Then when the machine posts again.You can enter the above settings when they are in press f10 again hit enter and they should be saved.

    On your problem:
    If you get the error message when you enter mit,the settings you see arent loaded.
    The mbrd will enter a default type state so you can "fix the problem"by putting in the correct values instead of having to clear the cmos by shorting the pins or whatever.
    If the warning screen comes up u should be putting in the right values and saving those.
    I dont know if you are actually saving the values shown or just hitting esc and "not saving changes" or what but if the warning is there.. you should be changing a setting and saving it,or reload and save defaults and start again.

    Sometimes if you save settings that are too extreme,the machine will go into a continuous "trying to post" loop.Hd will spin up lights come on then it shuts down for a second then it starts trying to post again.
    The soln for that (or at least that works for me and others) is hold down the power button until the machine stops trying to reboot.
    Then turn off the power supply switch. Leave it a minute or so just to be sure there is no residual current.
    Turn on the power switch and then hit the power button.You should get to the bios screen after 2-3 cycles.Then you can "fix the problem".
    Gigabytes dual bios in action ( I assume).
    It saves a lot of time pulling off the case cover and prodding around trying to short out the cmos jumper.
    Ive never had to do that yet on this board!

    Yours could be different on the above tho..since i dont have that board:0

    The actual board owners settings may be what to go for.. its just I had an urge your cpu is fairly close to mine.What is the real difference on these compared to ud3. is it just a bit of extra copper in the pcb?
