    Thanks. I'll try those settings. Hopefully that will clean things up.

    We'll give it a try as soon as my daughter gets off work (6 PM eastern). I was trying a few things. It seemed like one memory stick works fine at any number of settings. The second I put in every slot and she no worky.

    I'm hoping these settings will do it, but I fear it may just be an issue with that stick as opposed to being motherboard settings. Wish I had some mechanism to verify whether that stick is just defective and I'm wasting my time on the tweaks.

    I really appreciate the help. I actually did attempt to just run with one stick in multiple slots on my own, but apparently just chose the wrong one. Just figured one memory module was as good as the other. At the time, I wasn't sure it had anything to do with memory anyway. It's a bit inconvenient as we currently have it setup to require moving the video card each time we change the memory. I've got to ask her why she chose that slot. It looks like there is another slot option that is actually closer to the power supply.

    I'll update with actual results of our adventure once they're known or I run into another impediment <grin>.

    Have you tried running memtest86+ or the windows memory scanner? If you have faulty memory it should show up when you run one of those tests. Might be worth trying.

    Well, it booted with the single stick just fine after setting those values. Put in both and it is back to constant rebooting. Put in the 2nd memory stick and it does the same rebooting. Put the 1st stick back in alone and it boots up again.

    I think I'm concluding the one memory stick is simply defective.

    Would you agree?

    So in the same slot with the same exact settings one stick works and one does not? If so, yeap sounds like you have a faulty stick and will have to RMA the set. Sadly this happens with all ram manufacturers, I think they dont have very good quality control with mass production

    To be sure, what exact settings are you using for these one stick tests >>>>

    This is Just a template I use to ask people their settings, pay no attention to the numbers in it, replace with yours

    The settings we started with were just what you'd spec'd previously in the thread. One stick worked fine and passed all memory tests. Put the second stick in and it failed. Put the 2nd stick in the same slot where the first stick had been and the system failed to boot.

    We went and purchased some CorSair XMS2 memory and they're working fine. System has been running fine and passing memory tests.

    We're just returning the G.Slick memory for replacement

    So, We're going to have to get have to come back here to understand how to optimize the memory timing settings. I didn't know if there was some process to go through to keep adjusting the timing for best performance until it pushes it too far. How do you tell what the best settings would be.

    I haven't searched the threads to look for the process to settle on the timings, but until we get the other memory back, it won't matter. Unfortunately, the Corsair memory doesn't have the same latency values as the G.Slick.

    Thanks to all!

    Default Re: GA-EP45-UD3P not going to POST/BIOS setup

    I spent several hours tonight playing inthe BIOS and still am not having much luck. My board doesn't seem to like it when I try manually set a voltage for MHC core instead of using the AUTO setting. I tried voltages between 1.2 to 1.3 with little success. I was able to get it to POST at 1.28 but when I re-entered the BIOS is stated that there was a problem from overclocking or changing voltages. Any suggestions?

    x.clay,
    According to your RAM (Corsair Dominator DDR2-1066, 2048x2 MB @ 5-5-5-15 2.1v), try this few adjustment in your setting:
    MCH Core…………….....1.100V...........: (1.2-1.3V)-stability for 2048x2 MB
    DRAM Voltage ……....1.800V............: (2.05-2.1V) -check your DIMM voltage in the Windows)
    Try this first and if is still unstable set in Bios:
    Performance Enhance...................: [TURBO]
    Btw,
    in the Gigabyte latest bios thread,I add Virtual Bios for major Gigabyte MB.
