    Same results with GA-EP45-UD3P

    I'm having exactly the same issues with my Gigabyte MB and this memory. Again, if I put any sticks in slots 1 and 3 the system won't boot.

    What settings can be used for DDR800 performance? And, why is it with all the adjustable parameters, that the memory can't be made to be stable at 1066?

      This motherboard should be able to just pick up all the proper settings and run with it. The problem is that people do receive a lot of boards with issues. For example, try using one stick in slot 1 and see if that boots. If not, it's a motherboard issue because it needs to at least boot with slots 1 or 2 (individually) or with slots 1 and 3 with two sticks. Those are the main slots and if they don't even work then the motherboard is obviously bad.

      Some motherboards are super easy, some take a tiny bit of tinkering, but the rest are just bad.
      Try raising NB Voltage to 1.2V or 1.3V, if that doesn't help, then definitely give Gigabyte a call to see if they can RMA the board.

      DDR2 800 should be able to boot up on any setting. The motherboard is optimized for DDR2-800 so it should be able to run on all AUTO no matter what. Let me know the results and I will be able to further assist you. If you could make your own thread, that would make it much easier to track your progress as well.

      Thank you

        i cannot get the computer to boot if i run it anywhere close tot eh 1066 speed. it will work if i bring it down to around 800

        could someone also explain the different memory dividers this board has, as i am not very familiar with intel chips.
        also which of these would be best to use to bring it down to 800??

        x.xxa -> fsb 266mhz
        2.50a
        3.00a
        4.00a

        x.xxb -> fsb 333mhz
        2.00b
        3.20b
        4.00b

        x.xxc -> fsb 200mhz
        2.66a
        3.33a
        4.00a

        x.xxd -> fsb 400mhz
        2.00d
        2.66d
        3.33d

        any help is greatly appreciated. thanks

          dbazley, which memory package do you have? Have you stabilized the CPU overclock? Are you running 2 stick or 4 sticks? your timings are really loose for 2 sticks. For static tREAD value, set that to 8 or above, right now it's 3 so it's way too low. MCH Core only needs 1.2V if you are using 2 sticks.

          This board is tricky. It needs to be set at a certain MCH Latch for the respective system memory multipler. For 800, I would try 3.00a. Simply make sure memory frequency is picking up at ~800 and you should be OK. I'm really frustrated with this motherboard because we have had a lot of people with issues and this board is inconsistent every time. It becomes very difficult to troubleshoot when I have to troubleshoot the motherboard as well. Keep me posted on the results.

          Thank you

            thank you gskill tech
            i have made my own thread here, which has much more updated info:
            http://www.gskill.us/forum/showthrea...=5677#post5677

            so i need to set the mch latch and take it off auto as well??

            thanks

              Greetings.

              By this thread, should I assume I should run at these settings vs. the stock settings? Any benefits or drawbacks running stock?

                  I have the GA-EP45-UD3P v1.6 bios FB, G Skill Pi 8gb's 4x 2gb pc2-8500, after searching for the answers to get the memory up and running at 533mhz+ I found several things that had to happen outside of the settings for the MCH, DRAM,etc listed here. I had to set the LLC (line load calibration) to enable, the tRFC to 74 and the FSB to 375. Here is my CPUz validation link and a screen shot for CPU and Memory.

                    Also, I don't like seeing references to PC2-6400 when its PC2-8500

                    G Skill-- you should fix that, thanks for hearing my whine

                      Hey, thanks for the input and I just happen to have almost the identical bits and pieces so when 64bit time comes around, this will come in handy.

                      Cheers!

                        Q6600, G Skill Pi = 1125mhz

                        ******DISCLAIMER******
                        My set up information is provided below. The settings I use are an over clock of my CPU. My CPU is an Intel Q6600 which is normally a 2.40 GHz quad CPU. It is being cooled by an Arctic 7 freezer pro. A stock CPU cooling fan set up WILL NOT KEEP YOUR CPU COOL ENOUGH. My board is the Gigabyte GA-EP45-UD3P version 1.6 with bios Fb. It has a good 600 watt power supply and a decent graphics card (GTX 260)

                        The memory is G Skill Pi PC2-8500 (4x 2 GB for 8GB?s total) on a 64 bit OS (Vista Ultimate sp2) a 32 bit OS will only show and use 3.5gb?s.

                        I do not use the WINDOWS interfaces like EZ TUNE 5 or 6 to do the changes, ALL settings are done in BIOS using the MB Intelligent Tweaker (M.I.T.)

                          I have changed my Static tRead Value from 6 to 5, from the above settings post earlier. This improved overall memory performance and the system is still stable.
                          It is my understanding that changing this setting allows the MCH and DRAM to exchange quicker. The lower the Static tRead Value the faster it goes. I have learned that a reading of 8 for example is the equivalent of Standard DRAM, 6 is the equivalent of Turbo. I have also read that to get it down to 3 or Extreme is VERY difficult to get stabilized with an over clock. I have 5 working, will try a lower value later, but I am pretty sure that 5 is the best for my settings. There were a lot of calculations to figure out this number!!!

                          Anyone else on this topic?? G Skill are you here?? Would like some feedback--thanks, 4x64

                            Volts

                            In my case the only things I ended up doing was using the @Bios offered by Gig and then left all bios setting to bios except ddr voltage. Tried 2.1 @normal and it falled ramtest @ 3% then tweaked it to 2.o volt and it ran rock solid. From that point I moved all the setting to Optimal/turbo and tested stability once again with no failures an screewed the box closed and it's been rox solid every since..

                              Altitude, stock settings are only good for up to DDR2-800. Anything above would need to be manually set.

                              4x64, tRD is for adjusting the timing of each individual memory phase associated with the selected memory divider. You may know this setting by its more common name, often referred to as "Performance Level". Indeed the lower the value the better, but it is different for each moetherboard/memory. At the same time, although it does increase performance, you will not notice an obvious speed increase simply because of lowering this value one notch. Only with direct comparisons will you notice a slight enhancement.

                              Thank you

                                Well, I have spoke to soon, I am sending my 8500's back for an RMA refund and losning a restock fee

                                I cannot get them to work properly with the GA-EP45-UD3P v 1.6. I ran memtest86+ v 2.11 and they failed with more errors passing by than the national debt clock.

                                I am more disappointed than anything, but I have a set of 6400 Pi in the machine now and they are working fine, just not at 533 which was I bought the 8500 Pi's.
