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

    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

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

      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!

          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?

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

            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.

              @Brionj Ahh ok well nice to see you are up and running then. To optimize your ram you just have to lower timings one by one and test with memtest86+ as you go, really no other way to go about it.

              Xclay, please add your specs to your sig, and please do post what exact settings you tried that fail from my suggestions. What you have above is way to many Auto's to have tried anything I suggested

                I believe I was able to get almost all the recommended setting working with the exception of MHC Core and perhaps the advanced RAM settings. I will post a detailed list of BIOS setting showing what is working and what I have tried after I get home from work. Thanks again for your help.

                  K, sounds like maybe you just need me to give you things to change in smaller steps then so not all is changed at once

                    I applied the settings you posted with a MHC Core 1.05 and it booted up fine this time. Memtest is running but so far there are no errors. I guess I have one of those boards that prefers less than stock I won't know for sure until I get a restart from a BSOD but with Vista 64 that shouldn't be too long. Thanks for all your help. I'll let you know if I have any further issues. For now I'm holding my breath and hoping this fixes the reboot issue.

                      Nice to see! Ya, I think some BIOS's or Boards overvolt that by default for some reason, great to see it worked for you to use less.

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

                        I'm having a very similar problem to the original poster, with a similar setup:
                        MB: Gigabyte GA-EP45-UD3p
                        CPU: Intel Q6600
                        Video: Radeon 4850
                        G.SKILL DDR2-800, 2048MB x 2
                        PS: Corsair 750W

                        So, it's the same motherboard and the same memory as in his scenario.

                        I power up the system and all the LEDs come on (is this supposed to happen? I can't find a legend in the manual), the various fans come on (with the exception of the CPU fan...is this set to be temperature dependent by default?), and I can hear the HD come alive.

                        No post /BIOS setup comes up, and there's no apparent video at all, even though the video card fan is coming on so it's clearly getting power. I thought it was the monitor cable but I switched that out from an old analog to digital and still nothing.

                        Unlike in the other guy's case, mine doesn't seem to reboot every few seconds. The system just sits there, and again the only way to power down is to kill the power supply.

                        I've tried the original recommendation of taking a single DIMM and trying it in each slot, but that hasn't worked.

                        This is my 5th system build, but I'm at my wits end here. It's tough to troubleshoot with a system that seems blind ...I feel like it could be absolutely anything. Any ideas?

                              I'm having similar memory problems. The bios boot with only one stick of ram (either stick works fine), but will cycle on and off if both sticks are in place. I've tried both 1-3 and 2-4 configurations. Notably (and perhaps this is normal or a sign of board defect), but even with a single stick, it will only work in slots 1 or 2.

                              I've read every thread I could find here and at other support sites (best discussion here, IMO), and have changed settings many times. The problem still occurs.

                              Components:

                              Gigabyte GA-EP45-UD3P (Updated BIOS today)

                                I had to adjust my MCH voltage to get 2X2gb of 1066 RAM to work properly. I would suggest filling out the BIOS form that is posted all over this Forum so people can better advise you.
