    Default EX58-UD5 RAM ID Problem

    Hi, I have built a desktop system and am having some problems with it; the full specs are below. The problem consists of the bios not correctly identifying the amount of ram when all 3 slots (DDR3_1, 3_3 and 3_5) are populated from a cold boot if the system has been powered down for more than 2 hours. If the system is shut down for 1.5 hrs or less the problem does not appear (I haven’t tested between 1.5 and 2 hrs). Ways I have been able to rectify this problem is to adjust the memory settings in the bios (e.g. enabling / disabling the XMP profile, saving and quitting) after which the system works okay (sometimes take 2 or 3 goes) until the system is shut down for 2+ hrs when the ritual has to be repeated. I do not have any problems with any individual ram dimm in slot DDR3_1 or DDR3_3, I have tested them all without error in memtest86+ (2 passes each), or with a combination of 2 sticks, I have only had the problem with 3 sticks installed. I have run memtest86+ for 6 passes on the system when I managed to get all 3 dimms correctly identified without error. I have also run prime 95 for 6 hrs without error. If I try to run memtest86+ when the ram incorrectly identifies every test returns an error. Windows will blue screen with PFN_LIST_CORRUPT or MEMORY_MANAGEMENT between “starting Windows” and the login screen if the ram is not correctly identified by the bios. Any help would be appreciated.

    I have tried the following combos: 1. 1 x 2GB stick in slot 1 (white closest to CPU), BIOS finds 2GB, windows boots okay 2. 1 x 2GB stick in slot 3 (white middle slot), BIOS finds 2GB, windows boots okay 3. 1 x 2GB stick in slot 5 (white farthest from CPU), BIOS finds 2GB, windows boots okay 4. 3 x 2GB sticks in slots 1, 3 and 5, BIOS finds 4GB, windows fails to boot as discribed in my original post. I have tried each ram stick individually and they do not cause an error unless all 3 sticks are installed. Thanks

    well now you know that the ram modules arnt faulty maybe its a bios issue,i would update it to the latest one as it will fix alot of memory incompatability issues,read on how to flash using qflash on main page,all you have to do it download bios extract it and drag the bin file to a usb stick formatted in fat32 and then at splash screen press the end key and follw onscreen prompts,f7 is an old bios now

    I have the same RAM running great on my UD3R. With XMP enabled, try manually setting QPI @1.275 volts, set Vdimm to 1.60 volts.

    First off thanks for the ideas guys. I tried to flash my BIOS to F9m last night but Q-Flash did not recognise my USB stick, I will try again tonight with a different USB or a bootable USB drive. I also tried bumping my QPI voltage as suggested by flyfisher. I enabled the XMP profile1 (1600MHz 8-8-8-24-2) with Vdimm 1.6 and Vqpi/Vtt 1.28 V. The same problem occured. I then bumped Vqpi/Vtt to 1.34 V and the same error occured. I don't want to go any higher on Vqpi as 1.35 is the max under intel's specs. After upping the Vqpi to 1.28 V and booting to the post screen (on a cold boot); 4GB of RAM was identified again so I powered down the computer manually. After being off for a few seconds I then powered on again and the computer posted okay (Identifed 6GB of RAM) and booted to windows okay. Any other ideas?

    Only thing I can add is that I had a dual channel kit on a P55 board that passed Memtest+ fine but was unstable in Windows, kept failing Linx at stock. HCI memtest for windows threw errors. Next time it shows all 6 GB try memtest for windows (get it here) and see if you get errors. With 64bit you should run 8 instances and allocate 512Mb or so to each instance. The free version will stop on any error. If your RAM is good it should run at least overnight without any.

    Edit: Now that I thought about it some more, it would seem that DIMM slot 5 is the culprit. You tried all the sticks separately and in pairs in slots 1 and 3, and they all were good. As soon as you populate slot 5 the trouble begins. I am beginning to think this is a motherboard problem.

    I will give the memtest for windows a go - can't hurt anyway.

    I will be away for work for the next few days from tomorrow, so will run the test tonight and hopefully post before leaving. You never know, it might show something or at least let me rule the ram out as the problem.

    Thanks for the suggestions.

    I am back,

    After being away for approx 5 days (computer turned off but psu on at the wall and on at psu switch), upon powering on the computer rebooted 2 times and at the POST screen an error message appeared saying that the system was unstable due to overclocking and default values had been reset. The only modification that I was using was XMP enabled on the RAM (all voltages were "auto").

    I have run memtest86+ for in excess of 29 hours without fail, but when I run memtest for windows as recommended above by flyfisher I would get a failure within the first 1 to 1.5 hours (8 instances running, 512MB ram first 7, all available memory 8th instance).

    Thinking that there may be a thermal problem with the memtest in windows, I used speedfan 4.40 and HWMonitor1.15 to check the CPU core temps. They were okay but the voltages seemed way off. There are shown in the attached picture for idle conditions and given below for load (running prime95):
    CPU - 1.2V
    RAM - 1.52V
    +3.3 - 0.14V ????
    +5V - 5.08V
    +12V - 9.09V (HWM gives 9.28V) ???
    -12V - -16.23V ???
    -5V - -5.61V (HWM gives -4.22V) ???
    +5V - 3.63V (+5VCCH in HWM)???
    Vbat: 3.17V

    Maybe the problem is a PSU... Is it weird that the computer will boot with such bad voltages (I.e. could the mobo be incorrectly reporting the voltages)?

    Thanks again.

    Yes, temps don't get too high with memtest. I can't imagine your PSU is bad, but it's always possible you received a defective PSU. What does the BIOS report for voltages in system health? I wouldn't trust SpeedFan readings.

    Edit: Looks like BIOS doesn't report 12 volt reading. I use Everest which seems to report voltages OK.
