  • Trident 6GB PC3-16000 CL9 DDR3 & Gigabyte X58 Extreme

    Hi, I have been getting stability issues (crash with very little stress) when booting with memory upwards of 1800Mhz on my i7 920, through a 180 bclock and 20x multi. Turbo OFF, HT off.

    I have the same settings as proposed on the UD3 motherboard, expect for the specific memory timings (in red), which, when inputted manually caused the computer to crash. I did not pin point which of all, if not all the settings caused the instability, and the baseclock & cpu multi (in blue). I am currently running a stable

    In MIT (MB Intelligent Tweaker):

    CPU Clock Ratio - 20x
    QPI Link Speed - AUTO
    Base Clock Control - Enabled
    BCLK Frequency - 180
    Performance Enhance - Standard
    Extreme Memory Profile - Disabled
    System Memory Multiplier - 10

    Uncore & QPI Features
    Uncore Frequency - 4000

    DRAM Timing Selectable - Manual

    CAS Latency Time - 9
    tRCD - 9
    tRP - 9
    tRAS - 24

    Enter these for the other three as well.

    Channel A Timing Settings

    Advanced Timings
    tRC - 27
    tRRD - 4
    tWTR - 4
    tWR - 8
    tRFC - 60
    tRTP - 4
    tFAW - 20
    Command Rate - 1
    Round Trip Latency - 42


    Advanced Voltage Control
    Load-Line Calibration - Disabled
    CPU Vcore - 1.30V
    QPI/VTT Voltage - 1.55V
    CPU PLL - 1.900V

    PCIE - AUTO
    QPI PLL - 1.200V
    IOH Core - 1.400V
    ICH I/O - 1.600V
    ICH Core - 1.300V
    DRAM Voltage - 1.640V
    Rest to AUTO

    Thx for the advice.

    you might try command rate at 2, 1 may be a bit to much , also think tRFC should be higher, around 70


    Pls offer comments on support I provide, HERE, in order to help me do a better job here:

      Ok with a 2T rate and 70 tRFC it boots at 186 bclock. Had it running for an hour on F@H and played a few games. However, it is not Prime95 stable, crashed after litteraly 30seconds. Maybe worth mentioning, I have Load Line Cali on.

      Ideally my goal is to have it stable at this speed. 3.72Ghz (186 x 20) & 1860Mhz mem speed.

        Try lowering QPI/VTT Voltage to 1.4V. It may not need to be so high for 186 BCLK. For Uncore Frequency UCLK, simply double your memory speed, otherwise 4000 may be stressing the processor.

        Keep us posted on the results.

        Thank you

          So I tried those suggestions, but this it was very unstable. Within seconds of starting Prime95 the computer crashed. Also, I've tried with settings ranging from 1.4v to 1.48v with the most stability at 1.48. I would get a BSOD upon stress testing that mentionned both Too Much/Too Little QPI/VTT voltage, or insufficient vCore voltage. I havn't tried over 1.325 for 3.72 Ghz. Still in the dark here. Thanks for the input.

            That's a pretty good OC on the CPU, Intel rates the max vCore at 1.375 which prob means your good at least to 1.425-1.45 anyway. Might inch it up to 1.35 and see how that does, then work from there

              Good news. Inputted up to 1.375 in BIOS, meaning 1.34 in CPU-Z and had an OCCT stable overclock. Upped the QPI/VTT to 1.52 (that seemed to cause problems any lower). So will trime priming overnight. I'm confident in my cooling solution that my temps will not go over threshold. At 3.6 prime95 remained under 70.

                  Nowafter trying 1.375 vcore in bios the machine was p95 stable. Surprising to say the least.

                  If I can be of help I would gladly provide my bios settings for your future use.

                  I am now running the 2ghz kit at 1.86ghz under 8 8 8 24 timings + cpu at 3.72 ghz.

                    If you could post up your BIOS settings that would be great.

                      How are temps? Hopefully good, but even so, you might try dropping the vCore a bit at a time, and run test....ohhh, maybe overnight or something to get the vCore down to lowest possible while remaining stable.....just a thought

                          Looking good, assuming temps are good?

                            Yes, temps are fairly good 69 under full load (prime 95/linpack). Overall great experience with G. Skill. Will definatly buy again.

                              That's pretty good for C0 stepping. Thought most people had D0 but I guess I need to start asking because they don't seem to perform nearly as well as D0s...

                              Thank you
