    Default How do I overclock EP45-DS4

    Hello

    I want to try and overclock my MB and see, I have read a few things and I give below what I think I will need to do minimum.

    My aim is the run a FSB at 400MHz. I have 1066 RAM but at the moment 800 RAM is installed. So I was going with the 1/1 RAM ratio.

    MB Intelligent Tweaker(M.I.T.)
    Robust Graphics Booster ...............: Turbo
    CPU Clock Ratio ..........................: 9x
    Fine CPU Clock Ratio.....................:+0.0
    CPU Frequency ...........................: 3.6 (400x9)


    Clock Chip Control
    Standard Clock Control
    CPU Host Clock Control..................: [Enabled]
    CPU Host Frequency (Mhz) ............: 400 Mhz
    PCI Express Frequency (Mhz) .........:100
    C.I.A.2........................................Dis abled

    Advanced Clock Control [Press Enter]
    CPU Clock Drive...........................: 800 mV
    PCI Express Clock Drive.................: 900 mV
    CPU Clock Skew (ps)....................: 0 ps
    MCH Clock Skew (ps)...................: 0 ps


    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) ..............: 800
    DRAM Timing Selectable ................: [Auto]

    No idea on changing any voltages


    thanks

    Hi

    I see you mention on some votages that AUTO will overvolt it, would be be the case if C.I.A.2 was on SPORTS as well?

    Before I go into the details, could you tell given that you have suggested memory frequency is 900, would it be better for me to put in my dominator 1066-8500 2X 1G 2.1V RAM?

    I cannot understand why you say 900Mhz, if the CPU FSB is 400MHz, why do you need the memeory to be faster, and will it given that I am setting system memory multiplier to 2?

    Yes, that needs to be disabled for you to overclock and be stable as you are putting your own values in

    You can run your 800 ram at 900 just fine normally. But anyway, sorry I mis-typed that above, it is 800Mhz with the above settings!! I will edit it now

    You may also try this, but it may not be as stable >>>>

    I have set turbo and enhanced, as the only changes and hope the voltages at ok?

    Running F9 BIOS

    3DMARK6 orginal non-overclocked was 14810, with this setting I get 16112 approx 8 % increase, a few degrees hotter CPU fan from 1600 to 1800 on average. So overclocking get you some extra but not a lot or would I be better using SPORTS/RACING mode, SPORTS with F8 BIOS reached 15568 nearly as good and when not doing a lot, will return back to normal operation so I am unconvinced that overclocking permanently is of much use.



    COULD YOU TELL ME VOLTAGES I NEED TO SET FOR USING C.I.A.2 (SPORTS)

    For the hell of it, I stuck in my corsair dominator 1066MHz 8500 2G ram 2.1V (coloured pink in BIOS!!!)

    This produced the same results as with 800MHz ram!!
    Only difference is the memory multiplier is 2.66 here against 2.00 for 800MHz RAM. So, is there any way to get any better performance out of the RAM and therefore system without increasing the FSB if that is going to increase volatges or heat?

    Is the voltageS I set for CPU OK?

    I could not advise about using The boards built in overclocking settings as I have never used them

    If you do not want to overclock but want the best out of your ram set performance to standard and CIA2 off, and then manually set tight ram timings

    I think I am going to keep my present Overclock as it does not seem to be taking the temp (and therefore NOISE) much.

    With the RAM

    I orginally had corasir 800MHz ram, I changed it to dominator 1066 ram but both have produced the same 3DMARK6 score, around 16100.

    I set my FSB to 402, system memory multipier to 2.66, ie., (2*4/3) for 1066 RAM. For 800MHz RAM I had used 2.4., ie. (2*6/5).

    CPU-z shows that now RAM is running at 536MHz and before 400MHz.
    I notice with the 800MHz RAM the timing were 6-5-5-18, now with 1066MHz RAM it has gone to 7-6-6-22. This is becuase my DRAM Timing selector is set to AUTO, now is the case that I have to start reducing the timing until I start getting errors in memtest+2.01 and that is all I can do to maximise performance? I have also set performance enhance to enhance, not sure about this

    thanks
