    Default GA-EP45-UD3R/UD3 Overclocking for first time

    Hi guys
    I hav never overclocked a computer b4 and i've only recently built my own computer for the first time (with the help of my friend). He suggested me to overclock my computer and he said he would help but he backed out coz he didn't know how to work on my bios.

    i dnt know much about computers so bare wif me.

    heres my build

    motherboard: Gigabyte GA-EP45-UD3LR P45 DDR2 PCI-E
    processor: intel core 2 quad q8400 2.66ghz 4mb 1333mhz
    ram: Corsair TWIN2X4096-6400C5 4GB xms2-6400 unbuffered 5-5-5-15
    power supply: 750W "Antec" TruePower ATX
    HD: Samsung 1TB HD103UJ 32MB Cache SATA2 7200rpm
    CPU cooloer: Zalman CNPS9500
    graphics card: Gigabyte GV-N26OC-896H GTX260

    all my setting is on default and i would like to overclock if possible to atleast 3.60ghz

    thanks in advance

    I hate it when someone follows suggestions completely and makes it much easier for us to help them.

    Before you make any bios changes, save your current settings as a saved bios profile.
    From the main bios screen, press F11 to save your current settings, using a name like Default333Opt.

    We'll start with a 20% overclock.
    Once you've performed stability testing, we can go higher if temperatures are within safe limits.
    Your cpu cooler should be OK, but it is an older model that may not offer sufficient cooling at higher overclocks.
    Which brand/model is your computer case?
    What fans are installed in your case?
    What is the normal room temperature where your computer is set up?

    See the notes at the end of this post.

    The following settings will give you a 20% overclock.
    Change the red settings.

    note:
    You can save multiple bios settings.
    Save your modified 401MHz bios settings as a 2nd profile before you Save Settings and Exit (F10).

    Stability Testing:
    Run Prime95 (Blend test) for at least 8 - 12 hours (or longer) to test for system stability.
    Run RealTemp to moniotr your cpu core temperatures. Up to 60 - 65 (C) is acceptable during stress testing.
    HWmonitor is a good program to keep running to show voltages, temperatures and fan speeds.
    Links to these programs: Latest Overclocking Programs, System Info, Benchmarking, & Stability Tools

    Post your new bios setting and the results of your testing. If Prime95 generates any errors, tell us how long the test ran and which "worker threads" generated errors.

    Include a screen-shot that includes:
    Memset using the SPD and ">>" tabs
    cpu-z CPU screen
    EasyTune6 --> TUNER tab --> ADVANCE tab --> VOLTAGE tab (only the VOLTAGE tab is needed)
    HWmonitor

    Default Re: GA-EP45-UD3R/UD3 Overclocking for first time

    Hello everyone, I've just registered to ask some questions about overclocking Q8400 too. I don't mean to jack the thread or anything, buy after seeing this thread I think it's better to post my question here as the OP and me have exact same question about the same MOBO and CPU.

    ATM I'm at the office and not able to give my system information in detail, but I think the below should be enough for you guys to identify the problem.

    Code:
    My config: 
    GA-EP45-UD3R/UD3 Rev#: 1.1 Bios Version: F9
    C2Q 8400
    G.Skill 2GB*2 800 Mhz (4-4-4-12) @rated voltage 2.0-2.1
    OCZ Vendetta with Tuniq TX2
    I can O/C it up to 3360 Ghz just by changing FSB to 420 without having to adjust any voltage, but I start having problem once I go beyond that.

    I tried 3520 @440FSB without changing any setting, and it booted up fine but errored in Hyper IP, but computer didn't lock up and Hyper IP was still going even after the error message pop up.

    To cut the long story short, this morning, I managed to pass Hyper PI 32MB with the following adjustments (to the default setting, I mean):

    Code:
    CPU Voltage 1.362 (or something around that figure)
    CPU Termination 1.30V
    CPU PLL [Normal]
    CPU Reference [Normal]
    CPU Reference2 [Normal]
    DRAM Voltage 2.10 (rated voltage)
    DRAM Timing 5-5-5-15
    
    DRAM Performance Control
    Performance Enhance [Standard]
    Extreme Memory Profile (X.M.P.) [Auto]
    (G)MCH Frequency Latch [400]
    System Memory Multiplier [2.00D]
    Memory Frequency (Mhz) [880]
    DRAM Timing Selectable [Auto]
    
    All other settings are at default.
    My question is, is it dangerous to supply such voltage to this CPU? I suppose VCore should be OK since it's in Intel's rated spec but not sure about CPU Termination. I heard that CPU Termination voltage should be increased as FSB goes higher.

    Apart from the above settings, is there any other setting I should look into which may help me reduce the VCore? Actually, I'm not so sure now what causes the error in HyperPI, can it be RAM, Since its rated speed is 800Mhz at 4-4-4-12 but I run it at 880 with more relaxed timing "5-5-5-15".

    As of now, my idle temp is at around 41C (from core 0 which seems to be the hottest), and load is around 65C with room tempurature ~30-31. I think it's too high and wouldn't want to use it like that.

    If there is no other way to make it stable at lower voltage, I may consider reducing the FSB to 420 as at that speed I don't have to increase any voltage to get a stable system.

    Thanks for your help.

    @PrTv
    No problem with thread hijacking. You're using the same cpu and similar ram and mobo.
    Using "Normal" settings are not recommended.
    AUTO should be used when you're not manually changing many/most bios settings.
    It's possible that some of your other voltages might be dangerously high.

    Your Cpu Vcore is reasonable, up to 1.40 or a bit higher is OK if needed.

    Kimboy11 did an excellent job providing the information we need.
    Update your forum signature with your detailed hardware setup and post your current bios settings and we can help you in this thread or you can create your own thread.

    Your memory is a bit better for overclocking, so you will probably get somewhat better system performance.

    Thanks for your reply. I'll post detailed system information once I'm home (within 3-4 hours).

    BTW, referring to the red text above, if Normal or Auto setting is not preferable, should I type in the "Normal" figure myself? If yes, what figure I should use?

    I've read the post in your link and found that the suggested voltage for CPU Termination is 1.20. I'd like to know how far I can go with this setting, and is my understanding correct that CPU Termination voltage should be higher if FSB is increased e.g. 1.28 for 420-440 and 1.3x for 440-460.

    I've got the M/B for about 3 days and still have much to learn. I come from ATI RS600 chipset (Asrock 1333 FULL-HD) and found that the Intel chipset handles things differently (MEM - FSB divider and stuff like that). By searching this forum and reading, I've learned a lot already.

    Another question is, is it normal that when I press the power button the first time, the system briefly turns on for 1 sec; then off and then boot up normally. I heard that this is normal if the system is overclocked. Is there anyway to overcome this?

    I asked because I'm worry about my 4 HDDs. As you know, HDDs and everything turns on with the computer when power button is pressed. IMO, the brief on-off-on like this may create power surge which may reduce the life of some components, especially HDD.

    What do you think about this?

    Sorry for the confusion.
    "Normal" should NOT be used.
    AUTO is OK for most stock settings.

    When overclocking, some voltages will be badly over-volted.
    This is the main reason why the following settings in this post should be set manually:

    CPU Vcore --------------- 1.????? ------ : [Auto] <--- set to the 1.????? value displayed in your bios
    CPU Termination ---------- 1.200V* ----- : [Auto] <--- set to the value to the left (Auto over-volts this too much when overclocking) Auto is OK if not overclocking
    CPU PLL ------------------ 1.500V* ----- : [Auto] <--- set to the value to the left (Auto over-volts this too much when overclocking) Auto is OK if not overclocking
    Dram Voltage is sometimes over-volted when set to AUTO.
    When overclocking, some of these voltages need to be set manually to higher values.

    Some systems are not stable at stock settings with some settings set to AUTO.
    Many members have found that using the recommended settings in the post resulted in stable systems at stock settings.

    Cpu Termination (aka VTT) varies from system to system.
    The general guideline is that VTT should be set at least 0.05 - 0.10 volts lower than Cpu Vcore.
    VTT can have a major effect on system stability.
    I'm not aware of specific VTT recommendations at selected FSB ranges.
    My system is stable @ 492MHz with Cpu Vcore = 1.36875 volts and VTT = 1.26 or 1.28 volts. YMMV.

    Another question is, is it normal that when I press the power button the first time, the system briefly turns on for 1 sec; then off and then boot up normally. I heard that this is normal if the system is overclocked. Is there anyway to overcome this?
    NO, this is not normal, it is a sign of instability. When your system has passed extended stability testing, your system will not do the boot "2 step" dance.

    As you will quickly find out, higher voltages are not always better. For example, if you set MCH Core too high or too low, your system will have multi-boot cycles and/or system instability.

    The EP45 motherboards are awesome, but it takes some dialing in when you're performing moderate to high overclocks.

    @kimboy11
    MCH Core might be the problem.
    You originally had it set to AUTO, which might work with your o/c setup.
    You might have to try MCH Core = 1.05, 1.10, 1.15, or possibly 1.22 - 1.26 volts.

    If AUTO works, the ET6 screen-shot will show us what setting the bios used.
