    Default Problem with 8GB ram on X48T-DQ6

    I'm having a seemingly unsolvable problem with running 8GB RAM on my GA-X48T-DQ6 board..

    Problem is that I'm seemingly stable.. I can run Memtest, OCCT and Prime95 to no end.. All is fine and peachy.. BUT during normal use my PC locks up now and then. No bluescreen, no errors just suddenly stops in its tracks and I have to hit reset.. It mostly happens within the first 10 minutes of use, if I get past that I can sometimes run an entire day.. But if it crashes it can take 10 resets before I manage to get past the 10 minute mark..

    I'm running as of now optimized defaults with the following changed:

    Timings set to 9-9-9-24, and ddr3 overvoltage is at 0.15 and gmch overvoltage is at 0.300

    Also removed splash screen, USB legacy support and enabled USB keyboard support.. Rest is optimized defaults..

    The memory is Corsair XMS3 1600C9DHX

    And yes, going back to 4GB only removes the problem..

    I've tried the following:

    Updated bios (with optimized defaults loaded after etc)
    Updated chipset drivers
    Updated sound drivers (Haven't tried 8GB after this, but it crashed more often when sound was playing)

    And I have ofcourse messed around with voltage settings as most threads in here suggest when trying to get 8GB stable.. But as I said before, I'm Prime, OCCT and Memtest ok..

    CPU is a E8500 running stock speed, platform is Vista 64 HP

    To best advise you on how to get your config stable with 8GB RAM, could you fill in the following BIOS template? It may be a case of needing to loosen some sub-timings, or alter Static tRead a little. PLease note the sub timings are different to the main 9-9-9-24 timings, and are in the Advanced Timing Control section of the Motherboard Intelligent Tweaker section.

    You can cut and paste the following into your next post. Use the [code] tags to allow easier reading.

    Alright.. I put in the extra memory again, loaded optimized, post'ed, changed my settings to this.. I went a little up on the ddr3 overvoltage, as the below seemed to indicate standard voltage was 1.5, and my memory is rated at 1.8

    First thing I would try is changing the Performance Enhance from [Turbo] to [Standard]. Turbo sets more agressive sub timings that your RAM may not like. I'm not 100% sure but it may effect RAM timings and settings that aren't visible to change in the BIOS.

    You could try a higher Static tRead value just to eliminate it as a possible cause, though I'd be 99% sure that tRead=7 is fine, especially at 333MHz FSB.

    I would also check that you really do need that much MCH voltage. If I read your profile correctly you are giving the X48 chip 1.55V. This may be perfectly fine as I have no experience with X48 based hardware, however it may be a little too much causing an instability, maybe even a heat issue.

    I'll try and change both and get back to you all with the result in a day or so.. Should have crashed by then :-)

    Well, I almost wrote yesterday that it seemed all my problems were gone.. I had been stable since my last post.. But today I've had 3 crashes so far, so not completely stable yet, or something else is wrong with my system..

    If you are sure you have Performance Enhance on [Standard], and have tried varying the MCH voltage, I'm not sure what it could be.

    If you follow the following steps, you can turn off the instant restart after a blue screen. If you write down the name of the stop error, and also the error code, someone familiar with BSOD errors may know what it means.

    To disable auto reboots:

    • Click on Start and then Control Panel.
    • Click on the System and Maintenance link.
    • Note: If you're viewing the Classic View of Control Panel, you won't see this link. Simply double-click on the System icon and proceed to Step 4.
    • Click on the System link.
    • In the task pane on the left, click the Advanced system settings link.
    • Locate the Startup and Recovery area and click on the Settings button.
    • In the Startup and Recovery window, locate and uncheck the check box next to Automatically restart.
    • Click OK in the Startup and Recovery window.
    • Click OK in the System Properties window.
    • You can now close the System window.

    Oh I don't instantly restart, so I have no bsod or error code. It just stops in its tracks.. Usually with a sound crackle just as it goes

    Found something I missed. In your settings you say you have
    Command Rate (CMD)................: 1
    Does it show a 1T command rate in CPU-Z? Set it to 2T in the BIOS regardless.

    You won't suffer any performance loss, like you would with DDR (not DDR2) on an AMD system, and it could make a major difference and get you stable.

    Oh yeah, I remember that having a good impact back in the day :-).. I'll try it on 2T..
