    Default New Build GA EP45-DS3L stability issues

    Hi there.
    I have just finished the hardware installation phase of my first build. Relatively easy, but the hard part seems to be attaining system stability. This is my system.
    MB: EP45-DS3L (rev 1.0) F 10.
    CPU: Intel E6300
    RAM: Kingston Hyper X, KHX8500D2K2/4G (DDR2-1066 speed)
    PSU: SHAW, SN: C0, 680 W (generic PSU that came with my case)
    VGA: ECS 9400GT 512
    <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p>
    After setting up the specified RAM timings and voltage, I attempted to install Windows XP home several times and encountered freezes while copying files. I checked the bios again and found that the auto detected CPU clock ratio multiplier was at 8x rather than what I understand is meant to be 7x 266 for the stock 1.86 GHz for an E6300. So I corrected this and the CPU frequency is now correct at 1.86 GHz. Unfortunately Windows XP setup still freezes and I get freezes in memtest +86 and just randomly while looking at settings in the bios. I have tried running the rig with one stick of ram also in the DIMM closest to the CPU.
    Here are my BIOS settings minus the driver strength profile section which is all set to auto as advised by your template and any settings that were not present.

    Any help would be much appreciated. If there’s anything I have left out please let me know. Also, when these freezes happen in the bios, or in memtest, a hard turn off results in a restart of the fans and LEDs a few seconds later and gets stuck in a loop of fans and LEDs on, then off, then on, then off until you turn off the psu. This doesn’t happen turning off at the front button when the PC isn’t frozen, the PC functions normally apart from the freezes/restart loop. Also I know that my generic PSU isn’t the wisest choice but I was hoping that it would suffice for this rig, there’s nothing particularly high powered, the graphics card I am using does not even require extra power aside from PCIe.<o:p></o:p>
    Apologies for the length. If support for a complete systen is not provided here, my apologies. If you could just let me know so I can take this elsewhere. Any suggestions would be greatly appreciated.

    Oldmatey.

    Might try a command rate of 2 on your memory. Also can you se your Static tRead on that board? If you can try 8 or 9. Check your dram voltage is it set correctly?
    Is this overclocked? Might raise MCH core a click or two

    Start with loading optimized defaults.
    There are 2 "E6300" now, the old 65nm Core 2 Duo and the new 45nm Pentium Dual-Core, which one is it?
    Untill you installed windows you may want to leave memory multiplier and timings on auto as DDR-800 with 1.9v. More MCH may be needed too as conners said.
    For DDR-1066 this memory needs 2.2v.
    It would be a good idea to tun memtest86+ for several hours before you install windows to make sure there's no problem with the memory/configuration that may result in corupted windows installation.

    I feel like a bit of a fool. I should have mentioned I am fairly new to this. Yes my processor is a Pentium DC 2.8 Ghz. I thought I was buying the C2D E6200 and therefore I was very confused looking at the bios settings for the CPU after installation. Taken this and your advice into account, I have loaded up the optimised defaults and gave memtest a whirl just to see how far it would get through. Very similar result to before, didn't get a minute through before freezing. No errors though, just freezes.

    The memory timings are of course back to auto and I am now running at 800. So I will now raise the DRAM voltage to 1.9v from the auto 1.8v and experiment with these other suggestions and get back to ya. I'm going to leave the MCH voltage until last though as I am only trying with 1 2gb stick atm and I have read reducing it may help also. If all else fails I'll try tweaking it up a little and then down.


    Thanks for the help. Will let you know how it goes.

    Realy I can't understand Intel, it's like 3 years have passed we can recycle model numbers.

    Freezes with single memory stick or just with both of them?

    The auto 1.8v DRAM Voltage may be deceiving, at least my board set it to 1.9v even BIOS default settings show 1.8v, check BIOS HWMonitor.

    Default bus frequency is 200MHz right? With 200MHz bus frequency you will hardly notice any improvement with over DDR-667, have a look a an experiment I once made. IMO there's no point fighting memory speed if there's not much gain and lower speed is easier to get stable.

    Freezing with one and both.

    Having attempted everything above, I had a crack at turning the MCH core voltage down one notch. I saw LSD suggest in another post that this might help with the stability of an ailing EP45-DS3L. I'm ten whole minutes through a memtest without a freeze. Which is 9 minutes more than before. I'll leave it running for another 3 or 4 hours and then, if all is well, go ahead with the XP install and then see about reaching 1066. Hopefully Chike, 1066 will be an improvement where 800 isn't so much. Thanks for the help and I'll probably be back once XP is installed to fiddle with the RAM speed.

    Well, believe it or not, with an MCH core voltage set in the bios at 0.950, thats two notches below auto, I have reasonable stability. Windows is installed and memtest was clean after 2 hours with one stick.
