    Default GA-EP45T-UD3P: Old Board New Issue

    This old board, GA-EP45T-UD3P, has been trouble free for years; ran Win XP without issue. It's my home workstation, finally had to update to Win 7 x64.

    For preventive maintenance I cleared CMOS by installing a new battery and installed a new hard drive; all other hardware unchanged. Adjusted settings in the BIOS; RAM timings @ auto but did set RAM voltage to 1.55V (I remembered I had to bump it up originally). RAM spec is 1.5V.

    I started the system and it did the start/stop loop during POST. I remembered this also happening originally when I first used the board, I bumped the RAM voltage to 1.6V. Win 7 loaded fine as did software, updates and my personnel data.

    I started having some random BSOD's, sometimes at the welcome screen and others while browsing with IE. I set the RAM voltage to auto and checked PC Health; it showed 1.744V, that's a bit high! I installed HW Monitor, it confirmed 1.744V. That makes sense, HW Monitor and PC Health I assume use the same sensor/sender for data?

    I manually set the RAM voltage again, PC Health and HW Monitor show 1.664V. I ran "many" Memtest passes, no errors. I have not had a BSOD in 24 hours; only time will tell. All other voltages shown in PC Health and HW Monitor, CPU, 12V, 5V, 3V match in both and appear normal.

    My question: any documentation or known issue of this series motherboard displaying false high RAM voltage in PC Health?

    Thanks.

    We have next to no information about your hardware setup.
    Telling us that you get random BSOD's tells us nothing.
    You can run Resplendence Software - WhoCrashed, automatic crash dump analyzer freeware and post the BSOD report to provide detailed BSOD information.

    I've never seen any EP45 threads or posts that complained about inaccurate reported memory voltages .

    We need detailed information about ALL OF THE HARDWARE in your system.

    We can best help you after you create a detailed hardware list in the System Specs
    portion of your forum profile at the bottom of the profile page or in your forum signature.
    Be sure to include brand names and model numbers.
    When you are done editing or creating your hardware list, save the settings.

    You didn't say if you first loaded optimized bios defaults after clearing the CMOS.

    Please provide a link to the manufacturer's web page for your memory kit.

    Check out http://forums.tweaktown.com/gigabyte...tml#post295784, post #5 for some recommended bios settings for a stock EP45 system.

    It will help if you include a cropped screen-shot that has the following information:

    • Memset using the SPD and ">>" tabs
    • cpu-z CPU and Mainboard screens (several instances can be run at the same time)
    • EasyTune6 --> TUNER tab --> ADVANCE tab --> VOLTAGE tab (only the Voltage tab is needed)
    • CoreTemp screen [for your cpu's VID (Voltage ID)]


    Here are some individual sample screen-shots:









    note: Coretemp's VID displayed value will vary if EIST and C1E bios settings are enabled, possibly showing 1.10 volts when your system is idle.

    profJim,

    Thank you for your reply and assistance. I updated my profile and will start collecting the information you requested. It's Friday, might take me over the weekend.

    Yes, I loaded optimized defaults in the BIOS and made the following settings established from previous stable settings.

    RAM Link you requested:

    Silverline

    Current Settings:
    CPU Clock Ratio = 9
    CPU Host Control = ENA
    CPU Host Freq = 333 MHz
    PCI Express Freq = 100 MHz
    C.I.A. 2 = DIS
    Performance Enhance = Standard
    XMP = N/A
    G MCH Freq Latch = 333 MHz
    DRAM Timing Select = Auto
    Load Line Calibration = DIS
    DRAM Voltage = 1.68V (current)

    Guess my original question could have been clearer. The RAM SPD voltage is 1.5V, confirmed with Mushkin Tech. Voltage ceiling on the RAM is 1.7V. Why does BIOS DRAM Voltage setting of "Auto" set RAM voltage @ 1.744V shown in PC Health? When setting DRAM Voltage to Auto it does not display the selectable value, just actual voltage in PC Health & HW Monitor.

    Adjusted BIOS Voltage Settings & Results: (PC Health & HW Monitor both display the same actual voltage)
    Bios 1.5V = 1.52V PC Health = start/stop loop during POST
    BIOS 1.56V = 1.536V PC Health = start/stop loop during POST
    BIOS 1.58V = 1.568V PC Health = will POST, if RAM is cold will BSOD 60 seconds after desktop, restart and display "Windows Recovered From Unexpected Shutdown"
    BIOS 1.6V = 1.584 PC Health = will BOOT to desktop, random BSOD after start
    BIOS 1.62V = 1.600V PC Health = Boot to desktop no BSOD, random BSOD navigating Internet Explorer

    I wanted to try 1.65V; 1.66 in BIOS resulted in 1.648V PC Health. I set the BIOS to 1.68V on Wednesday, PC Health shows 1.664V. I have not had a BSOD in over 48 hours. That's why I questioned the accuracy of PC Health reading?

    In Windows XP x64, IE8, I had the DRAM V set BIOS 1.6V, PC Health 1.584V and the system was stable. Windows 7 x64, IE11, DRAM V BIOS 1.68V, PC Health 1.664V and I'm stable so far. I know Windows 7 uses more resources and this is less than .1V difference between 7 & XP; does this make sense?

    I will not be able to send you the error dump files unless it does BSOD again; I cleaned the error dump files in Disk Cleanup and reset system restore yesterday when all appeared stable. Over the weekend I will get the SPD, MemSet and CPUZ screen-shots you requested.

    Again, thanks,

    MDDI

    You're welcome.
    Some of the AUTO bios voltage settings are set "too high" to ensure that your system will boot.
    With some of the AUTO voltage settings, the applied voltage will exceed established safe limits.

    It's normal for the reported voltage to be somewhat lower than the manual setting that you use.

    You might have a problem with the auto-applied MCH Core voltage setting and EasyTune6 will display the current setting.
    With my 2x2GB Mushkin Blackline 1066MHz memory, the optimal MCH Core voltage setting was 1.26 - 1.28 volts. YMMV
    EasyTune6 will report the applied voltage for MCH Core.
    My Mushkin DDR2 memory was rated for 2.10 volts maximum and they operated best with tight memory timings at 2.02 volts.
    When I replaced win2k with win7, my Mushkin DDR2 memory settings did not need to be changed. It doesn't surprise me that this might not be the case with DDR3 memory settings with LGA775 motherboards.

    MCH Core settings that are too low or too high can cause instability and/or boot loops.

    I've seen many cases in the forum where P35 and P45 DDR3 systems had problems trying to run DDR3 memory kits at their rated speeds. In some cases the memory had to be under-clocked for the systems to pass stability stress tests.

    I'm including WhoCrashed and BSOD screen-shot examples because sometimes the displayed information is enough to help solve common BSOD problems. BTW, I don't read and analyze BSOD dump files, but I can often find possible online solutions, especially at BSOD Help and Support - Windows 7 Help Forums

    profJim,

    Again, thank you for your detailed reply. It's been a long time since I have posted on the forum, my system has been fine all these years. I used to PM with a member Lsdme, looks like he has not been active for awhile? All of you on the forum have been most helpful.

    In fact, I have to give some credit to Gigabyte; even though this board is out of warranty they have replied to a ticket I submitted; can't beat that! Although they did not give me close to the information you have, I don't believe other board manufacturers would have offered support out of warranty?

    The tech at Mushkin has also been very helpful. I bought Mushkin because of this Gigabyte Forum in the day. Mushkin has moved and gone through some changes, but still offer excellent products and support; and their products are made here in the US.

    This is my workstation at home; I'm not a gamer nor do I overclock. I do run a CAD program, Solid Works. This machine has been solid and dependable until Windows 7. I've reloaded the 7 OS several times and have personal data saved over all kinds of media; this has been frustrating!

    Today I had another surprise. I did have CPUZ installed with Win XP; just had not gotten around to installing on Win 7. I searched and went to CNet today (without thinking), downloaded CPUZ to desktop. I scanned the download with Malwarebytes and Avast before opening. Once I started to install, Avast popped up and I realized what was happening; another download program started!

    I shutdown the system with the power button immediately! Result; 104 PUP's, HATE THOSE GUYS! All is cleaned and well now and I downloaded CPUZ from the authors site. Confirmed, memory SPD is 1.5V.

    I believe I'm on the correct path; RAM voltage. Your suggestion to use Easy Tune 6 to check MCH Core V is well received. I never installed the utility bundled with the board when new; figured it was a tool for the tweaker enthusiast. I downloaded Easy Tune 6 utility from Gigabyte today and un-zipped to desktop (yes, I scanned the un-zipped file). I will use the utility this weekend; it's Friday evening and the Boss wants to go out (tired of me screaming at my monitor).

    If the MCH needs to be adjusted, possibly I can start reducing the DRAM voltage? Will advise; great advice.

    Cheers,
    MDDI

    Lsdme was the heart and soul of the TT forums and the last we heard from him was in late 2012.
    Lsdme's http://forums.tweaktown.com/gigabyte...1-week-so.html thread is sort of an unofficial log.

    The main goal is to get your system completely stable.
    It sounds like your system with win7 is borderline stable and we need to find the optimal settings that prove to be stable.
    You can run HWiNFO64 and enable logging so that you can periodically view the logged statistics and verify that there aren't any problems with voltages, temperatures and available free memory. The default logging interval is 2000ms (i.e. every 2 seconds) and you can change the logging settings by clicking on the Configure Sensors button. You can enable auto-logging or you can manually start and stop logging at any time. You can minimize the HWiNFO screen even while logging is enabled.
    HWiNFO, HWiNFO32/64 - Download

    Another thing to periodically check is win7's Event Viewer to see if any services or programs are misbehaving.

    As I recall, EasyTune6's default setup is to auto-start in the background with every reboot. I recommend that you disable this auto-start setting and manually start and exit the program instead of having ET6 always running in the background.

    If worse comes to worse, you can easily underclock your memory to 1066MHz by changing only one bios setting to see if this helps to get your system stable.

    Actually just attach the dump file to a post as a zip and I'll try and analyze it for you. Also you don't need a full kernel dump. do a mini dump. Jeeze people...

    profJim,

    I downloaded Easy Tune 6 from your link, won't run after install. Downloaded from Gigabyte, won't run after install. Installed from the original utility disk, won't run. There are some posts on Windows 7 Forum that Easy Tune 6 does not work with Windows 7 SP1.

    Last night while browsing "Internet Explorer Has Stopped Working" displayed, I closed, BSOD! First one in 3 days. I am confused, same machine, why Windows 7 and not XP?

    The MCH is supposed to be 1.2V +/-? The BIOS next to the selectable settings displays 1.1 (Auto). I went ahead and selected 1.2V. Without Easy Tune to see what the actual MCH Core V is; is there another utility available? HWiNFO64?

    WTFMAN, thanks for the offer. After all the East Tune 6 installs/uninstalls, the BSOD, resetting defaults in IE and setting the MCH Core 1.2V I wanted to get back to a clean start. I did a Disk Cleanup and a System Restore. If I have another BSOD I will gladly attach the error files.

    profJim,

    Easy Tune was working, first time it started in System Tray; didn't see it. After first start, now starts clicking the desktop shortcut.

    If I read this right, the Target voltage is not actual but what is set in the BIOS? The Power on is the Default?

    If you look at DRAM voltage, Power On is 1.5, Target is 1.68. 1.68 is what I set the BIOS but PC Health and CPUZ show 1.664 actual.

    MCH Core Power On is 1.1 default, the 1.2 is what I set the BIOS. So, we don't really know what the MCH Core actual applied voltage is, correct?

    profJim,

    My system did crash again this AM. It's frustrating and very strange. It will boot to desktop and stay there, no BSOD. If I browse with IE it may or may not crash; if it does it will not again all day as long as I don't shut down for more than a few hours.

    Obviously setting the MCH Core from 1.1V to 1.2V did not have a positive result. I do have a zip error dump file if you or any wish for me to send it?

    I have attached some of the screen shots you requested. I noticed on the RAM SPD that they are different. The RAM in slots 1 & 3 (channel A) were kit together, RAM in slots 2 & 4 (channel B) kit together. They appear to be programmed different. Although the total frequency is the same, sticks 1 & 3 JEDEC 1 - 3, sticks 2 & 4 JEDEC 1 - 4. Issue???

    I have not installed "Who Crashed" nor HWiNFO. Do you suggest one over the other or both?
