    New Build, Another Mem settings question

    Hello Gigabyte gurus, ,

    I've just built my new system-

    EP45-DS3 F6 Bios
    E8400
    4GB Kingston HYPERX PC6400 DDR II, 1.8v 5-5-5-15 ( 2 X 2GB) Kingston Technology Company - HyperX DDR2 -
    Vista64
    HD4850 etc etc

    I have had one BSOD and a few freezes while in windows, and I have read the suggested memory settings for the p35/p45. Things is the more I read on mem settings the slightly more confused I get. At the moment I am just running stock to make sure everything will stay stable, and then I will push the cpu to 3.6ghz.

    I have a few settings on auto, and have not yet adjusted the setting that is recommended for 2 x2gb sticks of ram. Should speed step be disabled or is this just done when overclocking?

    If I can have a guide on what I should have for a stable base, that would be appreciated.

    Many Thanks
    Ray

    Which exact kit do you have? Please find by model # and link me to the PDF or post the model # Thanks

    Speedstep can be disabled if you are not overclocking, if you want your CPU to run at full stock speed always.

    Once you link me to your exact ram I can best advise you. But for now you need to set performance enhance to standard, try 1.24-1.26 MCH Voltage, set your ram voltage manually and set trfc to at least 52-62. Once you get me your ram link, I can give you optimal ranges for all settings for 3.6 if you like

CPU Vcore….……….........................: All up to you are your chip/board.  Do manually set though.  Set it high enough so you can for sure boot then lower until it fails and then raise back up a few notches.  What you set here will be LESS actually applied in windows, so check this with CPU-z and keep that in mind.  Stock Set voltage may get yo 3.6, but maybe not.  I would guess 1.25-1.3 Actual will get it for sure

              Wow, it took me a while to actually do this!.

              Anyway, I've had 2 attempts with the suggested settings and both times the comp would not boot, it just turned off twice, then booted into windows. Checked CPUID and everything was still stock, although the BIOS still reported the modified settings. Strange.

                Success. This time I just changed the FSB and memory SPD settings only, and left everything else alone, even CPU Voltage. So far so good at 3.6g.

                Will see how it runs long term Temps are a nice 42degrees C as well.

                  It's very important that you set your Vcore (CPU voltage), CPU termination and PLL manually right away! Having these settings on auto can seriously over volt your components and cause hardware failure. For example the max recommended CPU term before you go into uncertainty is 1.4V. the board has been known to set 1.5V or more which is certainly, 100% dangerous.

                  If you can post a screenshot of Easytune 6 on the advanced overclocking voltage tab (a page full of sliders and two voltage columns labeled "Startup" and "Current") I or others can suggest settings for the bits that shouldn't be on auto. Easy tune 6 is on your motherboard driver disc or on the Gigabyte web site.

                  I can't stress how important it is that you do this. It may be that auto has been sensible, but it could equally be that your hardware is in real danger.
