    Default Overclocking The EP43-DS3 Advise Please..

I’ve just signed up after seeing some well-answered questions and helpful members from google searches.

    Ok I’m pretty new to overclocking and iv been playing and tweaking around for the past few weeks. Iv built my own rig and still upgrading it. Before my question here is the list of parts from my tower:

    Case: Antec 900
    Motherboard: Gigabyte EP43-DS3 With F9 Bios Update
    CPU: Intel Core 2 Quad Q9550
    CPU Cooler: Corsair H70 WC
    Memory: Corsair XMS2 1066 5-5-5-15 (Total Of 4GB)
    Memory Cooler: Corsair Twin Fan
    PSU: I-Cute 1000W
    Graphics Cards: Crossfired ATI Sapphire Radeon HD4850 (Total Of 2GB)

    Ok I think that’s all you need to know to help me with my question.

    I have noticed allot of users of the Intel Q9550 CPU seem to run between 3.8Ghz - 4.0GHz with no issues and no problems. Even people with not as good cooling nor RAM as me.

    Iv set my overclock at 3.40GHz and all is fine with nice low levels of Volts. Even the RAM at 2.00V.

    But if I try and go over 3.49GHz I get a double boot (overclock fail) and the factory settings of 2.83GHz loading up (kind of like the safe mode after overclock fail)

    I would have thought my mobo can handle over 3.40GHz so I’m not really understanding why I’m not getting any luck?

    Is there a setting I haven’t done correct? Or maybe some of you that have or had experience with this board could shed some light? Maybe suggest some voltages for me.

    Many thanks for the time. :)

    Paul

    What voltage is your memory kit rated to, should mention on the sticker or you can check with CPU-z in the SPD Tab (Post a pic if you are unsure)?

    Try this for 3.8Ghz, AFTER you do the following.

    Please go into your BIOS and load Optimized Defaults, then save/apply F10 and reboot BACK TO THE BIOS. Once in the BIOS again set your SATA/Disk settings back to what you need, this is VERY important if you are using RAID.

    Then you can move onto any other settings you need to adjust, and or the below adjustments. You are using Fail Safe now, which is probably part of why you were having issues before.


    MB Intelligent Tweaker(M.I.T.)
    Robust Graphics Booster ...............: Turbo or Fast
    CPU Clock Ratio ..........................: 8x
    Fine CPU Clock Ratio.....................: x.05
    CPU Frequency ...........................: 3.80Ghz (450x8.5)


    Clock Chip Control
    Standard Clock Control
    CPU Host Clock Control..................: [Enabled]
    CPU Host Frequency (Mhz) ............: 450
    PCI Express Frequency (Mhz) .........:101-103 (This helps the lower end chipset boards when overclocking, it will be fine to use, start with 101 if you are worried)

    C.I.A.2 .................................:[Disabled]


    Advanced Clock Control [Press Enter]
    CPU Clock Drive...........................: 800MV Optimized Defaults will set this
    PCI Express Clock Drive.................: 900MV Optimized Defaults will set this
    CPU Clock Skew (ps)....................: 0ps
    MCH Clock Skew (ps)...................: 0ps


    DRAM Performance Control
    Performance Enhance...................: Turbo << Standard
    Extreme Memory Profile (X.M.P.).....: Disabled
    (G)MCH Frequency Latch...............: [Auto]
    System Memory Multiplier ..............: 2.00D (This will be 900Mhz memory speed, so you may be able to use tighter timings, I'll note this out below)
    Memory Frequency (Mhz) ..............: 900
    DRAM Timing Selectable ................: [Manual]

    Standard Timing Control
    CAS Latency Time........................ 5
    tRCD ......................................... 4/5
    tRP'........................................... 4/5
    tRAS.......................................... 12/15

    You may be able to use any of the above configurations since you are running the memory under speed, 5-4-5-12 for example, or 5-4-4-12, ect.
    You may want to set 555-15 first though, then play with this later

    Set all Suggested below to highest Values first. Then later you can lower, one at a time, testing as you go

    Advanced Timing Control
    tRRD........................................... 3-4
    tWTR.......................................... 3-6

    This Ep43-DS3 or any P43 can't be overclocked above 420Mhz FSB, unless you found a way how.

    Thanks for getting backto me.

    Im not using RAID. I do have a secondary hard drive but just for extra data. I run windows off my 1T HDD.

    I cant set the over clock over 3.50 so i will try and do those settings that you just listed aftert loading load Optimized Defaults.

    Sorry im very new to overclocking and still learning.

    Oh the RAM is rated between 2.10V - 2.30V but usaly if i set at 2.10V i get a double boot just like if i try and go over 3.50GHz.

    i will let you know how i get on.

    Many thanks
    Paul

    No didnt work :(

    I just get a double boot and it then starts in std settings... Even if i set the volts higher.

    Am i better off buying a new mobo?
    Or can this mobo reach the speeds im looking for?

    Thanks

    Please post back the exact full settings you tried that failed, maybe then we can advise back.

    In general though, as mentioned above, the P43 chipset is not a very strong overclocker and has it's limitations, so yes if you have the spare cash and really want to overclock easier then a new P45 would be your best bet.
