    No problem. Good luck.
    Don't forget, you might need to set the 1066MHz manually too. You can see in the PDF, the standard settings are 5-5-5-18, 800MHz, 1.8V which is far from your memory max spec and you're losing out.
    If Kingston says it can work at 5-5-5-15, 1066MHz, 2.2V no reason not to believe them. But you can only reach that manually.
    Until recently I also thought you just need to stick in the ram and it will work as supposed to...until reading all this... :)

    Kantona , did you get your memory working at 1066 MHz, what settings and timings did you use ?

    No, I didn't even try. But my situation is different, my memory is PC2-6400, or 800MHz. Even though I had read that it can be OCed to 1066MHz on higher voltage, I decided not to risk my RAM or its lifetime with higher voltage.

    I am running AMD and they have different way for reaching the memory freq, which I wasn't even aware of. They use a divider CPU/n instead of multiplier like 2x or 2.33x CPU clock. So in my default situation I wasn't happy because it was:

    CPU 12.5x 200MHz = 2500MHz
    Memory divider CPU/7
    Memory freq 2500/7 = 357MHz, dual data rate 714MHz

    So my 800MHz memory which can go ever higher, was actually working at only 714MHz.

    Reading around I found out how the memory divider is calculated, and I decided to raise the CPU clock to 250MHz from 200MHz, lower the CPU multi to 11x and make the memory divider CPU/6. This way I got:

    CPU 11x 250MHz = 2750MHz
    Memory divider CPU/6
    Memory freq 2750/6 = 458MHz, DDR rate 916MHz

    I achieved this with default auto timings and voltage. And I'm happy with that. My CPU and RAM are slightly OCed, but not enough to stress them too much, and I don't need that anyway.

    I have been running this for months and it seems stable. I hope it stays that way. :)

    For your Intel you can play around more because you have separate memory multi to use. But I can't give you any timings or voltage from personal experience. As I said, the above works for me, and I have 800MHz memory so it's slightly OCed without any problems with auto timings and voltage.

    It's very important to run extended stability tests to ensure that your system is really stable. Even though your system appears to be stable with your bios settings, you risk file and/or data corruption when you system isn't stable. This means that you should run Intel BurnTest for 10 loops using the maximum amount of memory, i.e. 2047MB for a 32-bit operating system, or as close to 4096MB with a 64-bit o/s. The second test is to run Prime95 Blend test for at least 10 - 12 hours, longer is better. When I think that my system is stable, I run 3 different Prime95 tests for 24 hours each; Blend, Small FFT, and Large FFT.

    If you want additional help with your bios settings, please provide the following:

    1) List your system components in your signature.
    --> User CP tab (upper left corner of web page)
    --> select Edit Signature
    --> enter your hardware components (brand, model, etc.)
    --> include your bios version
    --> preview
    --> Save when complete
    Be sure to include your bios version, motherboard version, power supply, cpu heatsink/fan setup and the model numbers of all components.

    2) Link to your ram's full specifications.

    3) Fill in the generic bios template with your bios settings.
    --> Fill in Auto where appropriate.
    Use this P35 generic bios template to post your current "Extreme bios settings. Ignore the bios settings in the template and fill in the values from your setup.

    4) Include a screenshot that displays:
    Memset using the SPD and ">>" tabs
    cpu-z CPU and Mainboard screens (several instances can be run at the same time)
    CoreTemp screen [for your cpu's VID (Voltage ID)]

    Links for these programs are in the Latest Overclocking Programs, System Info, Benchmarking, & Stability Tools thread.

    My backup system is a P35-DS3L with an E2140 with a maximum overclock to 3.20GHz (100%) and runs 2x1GB of DDR2-800 memory overclocked to 1200MHz (Ballistix 2.2 volt version).
    My 24/7 setup only uses a 75% o/c (2.80GHz), with 3GB of memory running 4-4-4-10 memory timings at 875MHz.
    My system's nickname is SuperSlug.
