    I dont see your graphics card type or psu,number of hdd's/fans etc,maybe I missed it.
    Cpu overclocking increases power required a lot.If yo have a high power consumption gx card it could be a problem.My system is ok if I got a larger card or could run xfire/sli I might be in trouble.

    Anyway here is my template running 24/7 for 1-1.5years no real problems. I dont run below 490 cpu ref,but will turn the cpuspeed down from 4ghz to 3.92 and memory from 1000mhz to 980 on a hot day,just to keep temperatures down.

    It would realy help if you had your system specs in your forum signature.

    Why do you set vcore below default value? you might need even more than default.

    The absolute value of the reference value is not very important, with auto settings it is 63% of VTT, and DRAM Termination and references are 50% of DRAM Voltage.

    Have you ran IBT(Intel Burn Test)? If you have what GFlops and core temps do you get?

    Now after reading forums i have changed some things

    I set CPU termination to 1.2 and then i have set MCH Reference to 0.760 & MCH/DRAM Reference to 0.900. Then i set CPU termination to 1.28 again and i have seeen that MCH Reference set automatically 0.810 & MCH/DRAM Reference stay at 0.900.

    Well but i don´t understan-know if these voltages are higher o lower campared with the voltages that i had with values in AUTO. With this configuration i pass intel burn test (5 cicles and working now) But i don´t know if is better or worse.

    CPU Vcore….………...............1.2125..........:1.2065
    CPU Termination…..... 1.200V*.......: 1.280v

    CPU Referen.…………....0.760V*.......: AUTO (The problem I have set this value AFTER setting CPU Termination at 1.280v and now i´m not sure of the real value of this settiing )



    MCH/ICH
    MCH Core…………….....1.100V...........: 1.260V
    BEFORE MCH Reference….…….0.760V...........; AUTO (The problem I have set this value AFTER setting CPU Termination at 1.280v and now i´m not sure of the real value of this settiing )
    NOW MCH Reference….…….0.760V...........; 0.810V (I have set this value BEFORE setting CPU Termination at 1.280v )
    BEFORE MCH/DRAM Ref.…......0.900V...........: AUTO (The problem I have set this value AFTER setting CPU Termination at 1.280v and now i´m not sure of the real value of this settiing )
    NOW MCH/DRAM Ref.…......0.900V...........: 0.900V (I have set this value BEFORE setting CPU Termination at 1.280v )

    What configuraion is better?

    Excuse my english but this difficult for me

    Thanks

    MCH/DRAM Reference, DRAM Termination, and Channels reference change with DRAM Voltage not VTT.
    MCH Reference and CPU Reference change with VTT.

    If you are using default values leave them on auto, or when you post post like this:
    NOW MCH Reference….…….0.760V...........; 0.810V (0.76 @ 1.2 VTT)

    EDIT: what GFlops you had with IBT? Did you use standard or max stress level?

    Hello

    Intel burn test High level (the max i can pass because i use a WXP 32 bit.

    what GFlops 48.900 max approximately with value in auto and 48.800 max approximately setting values as i speak (MCH Reference….…….0.760V...........; 0.810V (0.76 @ 1.2 VTT & NOW MCH/DRAM Ref.…......0.900V...........: 0.900V )

    Thanks

    OK 48 GFlops is good for 3.8GHz.

    To set DRAM/MCH Ref, DRAM Termination, and Channels references, set DRAM Voltage to default 1.8v, set those options to 0.9 (50%) then set DRAM Voltage back to the value you want it.

    Ok Thanks

    Two questions
    1) I have tired MCH reference with (0.70 @ 1.2 VTT)0.750V, (0.72 @ 1.2 VTT) 0.770V & (0.74 @ 1.2 VTT) 0.790 always with CPU Termination 1.28V and intelburn test fail so i have to set
    MCH Reference….…….0.760V...........; 0.810V (0.76 @ 1.2 VTT)
    but this configuration is better, wrost or the same that
    MCH Reference….…….0.760V...........; auto

    2) I have a problem with my meemoris i crash always I attempt

    System Memory Multiplier ..............: 2.66D
    1133 MHz and i don´t know the way to resolve this problem.

    Thanks

    Auto and default .76 @ 1.2 VTT are the same.

    Please set DRA< references and termination to default first and even better to auto.
    You may try 2.66C multiplier, and/or MCH Reference above default (0.78+ @ 1.2VTT)
    Other things, VTT 1.3-1.32, DRAM Voltage 2.1-2.14v, Channel Driving Strength 1200/1066 (both channels), Static tRead Value 10 (both channels)

    There is a problem here:
    You can not expect your memory to easily reach its max rated speed while you are overclocking the cpu

    You have to get your mind around the fact that your memory may not work a its max rated speed with your cpu overclocked.
    Hold the cpu at its normal speed and seei f the memory will go to 1150mhz or hold the memory at a lo speed antd try to get a max cpu speed.

    If you check through the many many threads for quad core intel cpu on ep-45 gigabyte motherboards.: this is what you get

    maximum practical cpu ref=500mhz on air cooling.
    Many people hit a wall at 450cpu ref.the next "wall" comes around 480-500 cpu ref (1920-2000 fsb) if you like to look at it that way

    The mch chip doesnt allow both maximum cpu and maximum memory performance.

    I get 9-10gb/s bandwidth with my memory and around 57 on the latency.
    Your meomory may be cabable of more,but it doesnt matter.
    ddr3 memory and an overclocked i 920 might get 25-30gb/s .doesnt matter to us .

    Im just saying yeh you might get 1150mhz speed on your memory.maybe 1200 + even but dont gimp up the cpu.
    Get your cpu ref up aound 480+ amd work off that and you should see the maximum p performance

    Thanks everyone helped me.

    I have woorking and now I have a stable OC at 3.81 with

    CPU Vcore….………...............1.2125..........:1.2000
    CPU Termination…..... 1.200V*.......: 1.260v
    MCH Core…………….....1.100V...........: 1.240V

    and i´m happy with it. Maybe in teh future i tried take a better memory configuration (now at 1075 mhz)

    Thanks
