    Default EP45-UD3P + Mushkin 996599 Dual Channel..

    Hello, I just built a new system, which was my first build. I am running 2 sticks of 2 GB 996599 in dual channel mode. In bios for Memory Frequency the reading 1066-890. Is this normal? or shouldn't they both read 1066?

    Settings in DRAM Performance Control are

    Performance Enhance [Turbo]
    Extreme Memory Profile [Auto]
    MCH Frequency Latch [Auto]
    System Multiplier [2.00D]
    Memory Frequency 1066 890
    Dram Timing Selectable [Auto]

    Cas Latency Time 5 [Auto]
    tRCD 5 [Auto]
    tRP 5 [Auto]
    tRAS 15 [Auto]

    DRAM Voltage 1.800V [Auto]
    DRAM Termination 0.900 [Auto]
    Channel A Ref 0.900 [Auto]
    Channel B Ref 0.900 [Auto]

    Thanks for any help.

    As the memory is running at 890MHz I can see that you're overclocking and the FSB is at 445MHz. Set the system memory multiplier to 2.4D and the memory should be running at close to 1066.
    RAM and FSB speed are always linked, see the "overclocking basics" link in my sig for further explanations.

    In my bios which is F6, I don't have a multipler of 2.40D. I have 2.40B, 2.00D, and 2.66D. I have selected 2.4B and now memory frequency reads 1066-1068. Which is close enough I guess.

    Thanks for taking the time to reply Nickel. I have already applied some information from your posts to other members, and so far have a stable overclock of 4.22.

    Here are the memory Multi's and the straps they are on >>>



    What you are seeing, mentioning is what is confusing you I think
    1066-1068

    What you see on the left is just the default, the value on the right 1068 at the moment is the actual Ram speed. You can disregard anything you see on the left as it is just defaults that may be in use, have been used in the past, or in use in the BIOS right then

    If you need anymore help with your settings let us know, I can for sure help.

    Putting performance enhance on standard will help with stability alot. So will setting your MCH and ram voltages.

    MCH/ICH
    MCH Core…………….....1.100V...........: << 1.2-1.28
    MCH Reference….…….0.800V...........; <<< Leave
    MCH/DRAM Ref.…......0.900V...........: <<< Leave
    ICH I/O……………….....1.550V............: <<< 1.55
    ICH Core…………...……1.100V............: <<< 1.14

    DRAM
    DRAM Voltage ……....1.800V............: 2.0-2.1

    Thanks for the reply and offering to help Lsdmeasap. This is the first system I have ever built, and my first overclock. I have just finished testing the system and is stabe at 20 hours of Prime95/Blend and 18 hours on Orthos. Can you please tell me if my system settings are alright? ... especially for 24/7 use..

    CPU EIST Function.........................: [Disabled]
    Virtualization Technology................: [Disabled]

    Temps under load using Real Temp and Core Temp, never got over 52c.

    Some of my default values, are different then the default ones in your last post, for instance:

    In my bios default ICH I/O is 1.500v you have default at 1.550v. Is there a reason for this? Do I have to make a change? Thanks for taking the time to help Lsdmeasap. I know your very busy.

    20 hours is a good long run, that is for sure likely stable for 24/7 use. Where you go from there is up to you, I mean do you want to tweak things for better performance, or try to lower voltages?

    I think the default ICH Voltage may have been from a different board in my template is why. You can use 1.50 or 1.55, as I always had used 1.55 without issue

    I do see some of your settings are mistyped or incorrect, like performance enhance there is no "Enabled" setting, and it should be set to Standard

    As for the rest, I need to know what your plans are but I can say All Auto for your memory is not the best for performance. Extreme Memory Profile [Auto], should be disabled

    You get 4.3Ghz on 1.29 Vcore? WOW, that is a good chip!

    Ahh no worries about helping, that is why I am here! Sorry for the late reply, terrible connection the past several days has kept me offline

    Lsdmeasap, I would like system tweaked for best performance. Higer voltages are fine. You are right about mislabled Performance Enhance... it should have been set on "turbo". What changes would you like me to make? Thank-you Lsdmeasap.

    Ahh ok, well please post me a screenshot of this program running so I can see what all those Auto's are giving you for now >>>
    Tweakers.fr ~ Memset

    Performance enhance on standard will give you much more stability and allow you to better tweak things yourself

    K, you may be able to make these changes. Do go slow with it testing things after a move or two so you dont get lost as to what is causing the errors >>>

    Robust Graphics Booster [Auto or Fast]
    CPU Clock Ratio [9x]
    Fine CPU Clock Ratio [+0.5]
    CPU Frequency 4.35 GHz 458x9.5

    CPU Host Clock Control [Enabled]
    CPU Host Frequency [458]
    PCI Express Freqency [100]
    CIA 2 [Disabled]

    Advanced Clock Control [All Default-No Changes]

    Performance Enhance [Turbo] << Standard
    Extreme Memory Profile [Auto] << Disabled
    MCH Frequency Latch [Auto]

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

    Load Line Calibration [Disabled]
    CPU Vcore 1.18750v [1.29375v] << A bit more may be needed, then less Vtt would be needed (Yes it would be better, if you could work it that way, but you can do that last/later) Less than Vcore is suggested

    CPU Termination 1.200v [1.300v] 1.24-1.3
    CPU PLL 1.500v [1.500v - 1.58V]
    CPU Reference 0.760v [Auto]

    MCH Core 1.100v [1.200v - 1.24v]
    MCH Reference 0.760v [0.743v](If you raise this or Lower Vtt this will adjust on it's own, just so you know before you wonder what happened, it will be fine as long as you are sure .74% was good for you) And This may be wrong/bad amount you have here. What is it when Vtt is set to 1.2? That is how you set it, see my signature incase you are not aware of how it works.

    MCH/DRAM Reference 0.900v [Auto]
    ICH I/O 1.500v [1.500v - 1.55V]
