  • Crosshair IV AMD 1090t GSKill Trident 4GB (2x2GB) ~ overclocking ram above 1600mhz

    Hi
    My current system is:
    Crosshair IV
    Amd 1090t (stock speed 3.2GHz)
    F3-16000CL9D-4GBTD GSKill Trident 4GB (2x2GB) DDR3 PC3-16000 2000MHz (9-9-9-27)
    And a corsair hydro H-50 cooler,

    I have successfully got my system running at 1600MHz stable - current stable config:
    Ram speed: 1600MHz
    Ram timings: (7-7-7-21-1T)
    DRAM Voltage: Auto 1.66v
    cpu multiplier: x20.5
    fsb: 200
    CPU frequency: 4100MHz
    CPU Voltage: Actual 1.42v (Keyed in value 1.405v)
    CPU/NB: Auto (1.171v)

    I have ran prime95 for a few hours and it is completely stable. I did have it running stable at 4.2ghz using a multiplier of x21 and cpu voltage 1.5v but with my case closed temps were getting too high (and it shut down) - so I had to reduce the clock a bit.




    I then tried running at the ram at
    Ram speed: 1866MHz
    Ram timings: (9-9-9-27-2T)
    DRAM Voltage: 1.6v
    cpu multiplier: x13.5
    fsb: 233
    CPU frequency: 3145MHz
    CPU Voltage: actual 1.37v
    CPU/NB: Auto (1.158v)
    Everything else is set to auto

    And it is unstable - I have increased the cpu voltage all the way up to 1.5v and it still remains unstable. I have tried increasing the CPU/NB by 0.1v and it still remains unstable (following advice given on previous support topics).

    Im unsure what to try next - do you have any ideas what to try now?

    When trying 2000mhz the computer is very unstable (actually the stress test doesnt get to reach 50% cpu utilization before errors occur).

    I have also enable cpu load-line calibration and cpu/nb load-line calibration

    Thanks Sammy,

    Ps. If you need any more info please ask and I will post it here

    You need to overclock the CPU NB Frequency and also increase CPU-NB Voltage.

      Hi thanks for the reply - I have just tried overclocking the cpu NB frequency and cpu-nb voltage and here are my results,

      (other settings)
      Ram speed: 1866MHz
      Ram timings: (9-9-9-27-2T)
      DRAM Voltage: 1.6v
      cpu multiplier: x13.5
      fsb: 233
      CPU frequency: 3145MHz
      CPU Voltage: actual 1.37v
      CPU/NB: Auto (1.158v)

      Here are all the different configurations of frequency and voltage I tried for the CPU NB:

      1) Setting CPU NB Frequency to default 1864Mhz (same as ram speed)
      Setting cpu/NB voltage normal (1.158v) ~ unstable
      +0.05 (1.2v) ~ unstable
      +0.1v (1.25v) ~ unstable
      +0.125v (1.275v) ~ unstable

      2)Setting CPU NB Frequency to 2097mhz
      Setting cpu/NB voltage normal (1.158v) ~ failed to boot
      +0.05 (1.2v) ~ unstable
      +0.1v (1.25v) ~ unstable
      +0.125v (1.275v) ~ unstable

      3)Setting CPU NB Frequency to 2330MHz
      Setting cpu/NB voltage normal (1.158v) ~ unstable
      +0.05 (1.2v) ~ unstable
      +0.1v (1.25v) ~ unstable
      +0.125v (1.275v) ~ unstable

      4)Setting CPU NB Frequency to 2563MHz
      Setting cpu/NB voltage normal (1.158v) ~ unstable
      +0.05 (1.2v) ~ unstable
      +0.1v (1.25v) ~ unstable
      +0.125v (1.275v) ~ unstable

      All configurations were unstable

      Any other ideas on what may be causing this. Here are some pcitures of the bios settings (with cpu nb and frequency set back to auto):


      CPU/NB Frequency (1864MHz)
      HT Link Speed values (233Mhz,466mhz,..... etc)




      Thanks again for your help

        Use Manual settings instead, over DOCP.

        Leave CPU Voltage AUTO.

        Set CPU-NB Voltage to 1.30V

        Let me know how that works.

        Thank you

          Thanks for the reply,

          just tried using manual settings with cpu voltage on auto - increased fsb to 233mhz to bring ram up to 1864mhz and it was unstable.

          I then tried upping the cpu-nb voltage to 1.3 and it is still unstable

          Any other ideas?

          Thanks again for all your suggestions so far - I really appreciate the help

            just testing increasing ht link speeds voltage - will post back progress

            edit: no luck with increasing ht voltage to 1.30v

              Try higher memory voltage. Not sure why at DDR3-1600, AUTO was at 1.66V?

                Thanks - it worked

                Upping the dram voltage to 1.70v made it stable at 1864MHz (8-8-8-24-1T),

                Now to test 2000mhz - will post back results later

                Edit: 2000mhz was not stable - tried upping dram voltage to 1.9v with no luck (9-9-9-27-2T),
                Tried upping the cpu/nb voltage to 1.30v and it was still unstable
                Tried upping the cpu/nb frequenccy all the way up to 2500mhz with no luck

                  Send the memory in for new replacements and try a new set.

                    F3-16000CL9D-4GBTD GSKill Trident

                    I finally got this ram stable at 2000 mhz on crosshair iv formula
                    bios settings: DOCP-9 10 9 24 .I set EVERYTHING on auto including timings,and set ram
                    in GANGED mode.
                    I have tryed every setting possible nothing worked until i set the ram in ganged mode.

                    hope you have the same luck as me. Gus

                      ps cpu multiplier at x16
                      I would attach prime 95 results but i guess i don't have enough privileges

                        how did you do it

                        I was just wondering what your settings are..that made you able to get your memory upto 2000mhz..I have an Nf980-65 motherboard that is suppose to be able to do 2133..but I can't even get my memory above 1600..when its Gskill 2300...i have tried everything..changing voltge, mem timings, FSB, CPU NB voltge..won't go over 1600..doesn't boot anytime I do..my settings as of right now

                        CPU 4100Ghz 20.5 ratio with 1.45v
                        FSB 200
                        HT and CPU NB 2600 with 1.50v
                        Memory 1600mhz all auto with ratio 1:4

                          Edit: just tried it in ganged mode (the docp timings for me were (9-10-9-27-2T)) with everything else on auto and it was unstable

                          Thanks

                          And - as for sending the sticks back and getting a replacement, looking through the g-skill forums and the asus forums it seems lots of people are having problems with these sticks and im thinking the problem may be caused by something else (and not that everyone has faulty sticks) - I dont want to give up on these sticks just yet

                            There is no problem, you just have to overclock the CPU properly. It is slightly more difficult on the AMD platforms.

                              True it does seem more difficult - that person seems to be one few who has achieved 2000mhz. And its not just g-skill sticks - theres a lot of support threads for other brands (including corsair dominator GT's).
                              Being the first amd board to support 2000mhz ram, im hoping that its some minor stability glitches that can be ironed out in a future bios update (fingers crossed).

                              As for overclocking - ive reached the limit of my current cooling system (corsair hydro h50) and can only ever achieve a maximum of 4.1ghz due to cpu temperatures going too high ,

                              I will have to invest in a proper liquid cooling solution and a new case to carry on this overclock - but first come, first i need a new graphics card (currently running a gtx260 )

                              I will try to see if I can get the ram running at tighter timings by lowering their speed a bit tommorow - will post back results (if successful)
