    Default GA-X48T-DQ6 cold boot issue

    Hi,

    I've been looking through these forums, and others with no luck so far on my issue.

    Anyways.. Systems specs first

    GA-X48T-DQ6 running an E8500 cpu.
    Memory is a 4gig kit of Corsair TW3X4G1600C9DHX (XMS3 kit)
    8800GTS card, Fortron 600w PSU and a few harddrives..

    Only thing I have tweaked is the DDR3 overvoltage which is +0.3 as per Corsairs recommendation (asktheramguy.com). This helped me to turn this issue into only a cold boot one, and not a "woohoo I booted" one :-).. Oh and I updated the bios to the latest non-beta bios from the gigabyte site.

    Whenever I have my memory in the green slots my pc won't cold boot on first try. It just hangs at POST when it's testing the memory. At the memory part of the POST screen it just hangs at "memo" and no more. If I press the reset button it completes post, but hangs a liiiittle bit at the memory test..

    I just tried changing the modules to the pink slots, and for now it seemed to work.. I'm planning to run this pc with 8Gig in the near future, but if I have a problem board, I'd rather find out now..

    So is there a general issue with running memory in only the green slots? Or are my green slots simply not powering up correctly or something?

    You need to set several things for 4gb or 8GB other then just the ram voltage, you should manually set trfc to 52-62, and add some MCH Voltage as well

    Yes though, your board could have issues with some slots, only way to check that would be to test each slot with a known working stick one by one with memtest86+ >>>
    Memtest86+ - Advanced Memory Diagnostic Tool

    If you do find some slots error always and others do not then you should think about a RMA on that board before you get more ram for sure

    I've been running memtest for 10+ hours in the slots at default speed without a hickup with both sticks in the green slots.. It's mainly a cold start issue..

    What do you suggest I set MCH Voltage to?

    You should set the Ram voltage for sure, likely 1.7-1.9 see your ram sticker to be sure, and for MCH You should set to +0.15V -.25V

    A 10 Hour memtest86+ stable likely means you can just add MCH +.1-.15 and really likely points to you needing a small bump in CPU Voltage to overcome cold boot issues

    My memory is rated for 1600 @ 1.8 v.. Right now I'm running everything stock @ 1.8v (1033mhz)..

    I can't seem to get a stable system with any overclock.. Even tiny OC's and I get instability.. But I didn't bump either MCH or Vcore.. I'm read alot about not putting too much power into the E8500's, so I'm not to keen on pumping extra into that.. I did try I think +.15v on it once just to see if it made a difference at the settings I had there.. Didn't help stability, but temps stayed well within norms (36 celsius at load).

    I should be able to run 1600 @ 1.8 9-9-9-24 on my memory..

    What you do not want to do with 45nm cpu's is put too much FSB/Vtt voltage into them. Additional Vcore and MCH will be needed to overclock

    Please post me your full settings you are using now, and what you would like to run and I will post back some recommended ranges >>>

    I still seem to be having these issues.. I'm at .1125 (the setting above .1) MCH voltage and +0.3 DDR3 overvoltage..

    You mention CPU voltage.. How much can I add on that? It's really odd.. I hang at cold boot, but only need to press the reset button and I boot up fine - although memcheck takes a little longer than what's comfortable (~10 secs)

    4GB needs +0.2 or more, please fill in the template above with your settings and I will advise back. The MCH voltage you are trying is not enough for sure, but others settings matter very much as well

    CPU voltage, depends on your speed really. But I would advise not going about 1.36 or so Actual (not BIOS setting)

    Please post your full settings and I can easily advise you on all things what you can or should be using

    Alright, here are my settings. I'm not aiming for any speeds before I get a system that can cold boot 100% of the time..
    Memory is rated at 9-9-9-24 @ 1.8v (I see I mispelled at the top.. It's ofcourse XMS3 memory - I corrected my org. post too.. )

    You did load and save/apply Optimized Defaults after you updated the BIOS right? If not you need to do that for sure as it is part of the proper BIOS flash and things will not be updated correctly if you did not. See here if you haven't about BIOS flashing >>>
    http://forums.tweaktown.com/f69/bios...h-guide-27576/

    See if this will help you get stable. This will be only 1333 ram speed though, just so you know. At your FSB that is the highest they can be running at now anyway, and likely Auto for your memory multi is not setting them that fast anyhow. If you want to run 1600 you will need a higher FSB. These are also the timings you would use for 1600 speed, so the main timings of 999-24 can likely be less for sure

    Robust Graphics Booster___________ [Auto] Or Fast
    CPU Clock Ratio ____________ [9]
    Fine Clock Ratio ____________[0.5]
    CPU Host Clock Control_ [Disabled]
    CPU Host Frequency (MHz)__________ [333]
    PCI Express Frequency (Mhz)_______ [100]
    C.I.A. 2__________________________ [Disabled]
    System Memory Multiplier (SPD)____ [4.00B]
    DRAM Timing Selectable_______ SPD __ [Manual]

    Performance Enhance = [Standard]

    CAS Latency Time________________ 9
    Dram RAS# to CAS# Delay_________9
    Dram RAS# Precharge Delay______9
    Precharge Delay (tRAS)__________ 24

    Set to all highest below, and then lower one at a time testing as you go with memtest86+ If you would like to leave them in Auto you will have to at least set Refresh to act delay for 4GB of ram

    ACT to ACT Delay (tRRD)_________ 4-7
    Rank Write to READ Delay________ 9-12
    Write to Precharge Delay_________ 12-16
    Refresh to ACT Delay______________ 62-80
    Read to Precharge Delay__________ 4-8
    Static tRead Value_______________ 8-12
    Static tRead Phase Adjust________ [Auto] << always leave

    CPU/PCIEX Clock Driving Control [800mV]
    CPU Clock Skew Control [normal]
    GMCH Clock Skew Control [Normal] << May want to test 50-150

    System Voltage Control____ [Manual]
    DDR3 OverVoltage Control__ [+0.30V] = 1.8V
    PCI-E OverVoltage Control_ [Normal] +0.1 for stability
    FSB OverVoltage Control___ [Normal] +0.1 for stability
    (G)MCH OverVoltage Control [+0.2V - +0.3V] << Needed for stable 2x2GB
    CPU Voltage Control_______ [normal] << or Auto

    EIST and C1E below will Have to be disabled once/if you start to overclock (Just keep in mind)

    Limit CPUID Max. to 3.....................: [Disabled]
    No-Execute Memory Protect............: [Enabled]
    CPU Enhanced Halt (C1E)................: [enabled]
    C2/C2E State Support....................: [NOT AVAILIABLE]
