  • Only JEDEC 2133 works with F4-3600CD-16GVK

    System specs:
    OS: Windows 10 X64 (build 10586)
    MOBO: ASRock Fatal1ty Z170 Professional Gaming I7
    BIOS: P1.60 (latest version)
    CPU: 6700K (BX80662I76700K) @ Default 4-4.2GHZ
    RAM: Ripjaws V, F4-3600C16D-16GVK, (PC4-28800, 8192MB x 2, CL16-16-16-36 1.35v)

    Ram is installed in A2, and B2 slots, also known as slot 2, and 4; These are the Priority 1 slots found in the Dual channel Memory Configuration table for my MOBO.

    Both XMP's don't work:
    XMP1 = 3600 @ CL16-16-16 1.35V, and
    XMP2 = 2700 @ CL15-13-13 1.2V

    I tried loading the XMP1 settings, with the speed of 3200MHZ, instead of 3600, but I still get memory errors, and blue screen crashes; so after that I also tried boosting the ram Voltage above 1.35V, but that didn't help; then I tried boosting the VCCSA over 1.3V, and that still didn't stop the memory errors, and the system crashes either.

    If anyone has some suggestions please help me, and if anyone else has the same ram, please post all your timings, so I can copy them into my BIOS, I'm pretty sure my BIOS isn't choosing all the right timings.

    Try one module at a time at 2400, 2666, or 2800 to see if it can be stable. Determine if both sticks have he same problem, or only one stick is not performing as it should.

      Tested

      I tested both Ram sticks, they both are having the same issue, and are unable to reach XMP.
      I was able to achieve 2962 MHZ @ 14-14-14-30, 434(tRFC), on Single, and Dual channel... so far it's stable.

        Suggestions?

        I would prefer speed over latency.
        Do you have any suggestions, on how to reach 3466, or 3600 MHZ, even if I have to loosen timings?
        My mobo does show other modules tested, and capable of doing 3466 @ C16, and 3600 @ C17; I'm just not sure how to do all the other timings to get it stable.

          Can you post pictures of BIOS?

          Did you disable power saving features and other options that may hinder performance or overclock ability?

            Those type of settings I kept on default.

            BTW, system worked a few days at the ram setting I mentioned earlier (2962MHZ, C14), then it started crashing constantly, so I reduced it to 2929, and the crashing stopped for a couple of hours, but then it started crashing constantly again so now I have reduced to 2829MHZ changed latency to C14-14-14-34, and will continue testing at that speed....

              BIOS pics

              Here's the failed timing pics, the Dram frequency has been tuned down to 2829, and (tRAS) is now 34.

                  Disable SpeedStep and C State and see if stability is better.

                    I might have had an issue with my PSU, but it's been replaced with a brand new EVGA Supernova P2 1200W, that way I can keep my C-state settings on, and my system stays stable.

                    I still have issues with the limitations of my mobo, it won't let me do XMP speeds. I need the timings for the Gskill F4-3600C17D-8GTZ.
                    It's on the list of compatible ram for my mobo, I think if I use similar timings I could get my ram to run at 3600mhz, hopefully at 17 CAS.

                      It doesn't work like that, there's no power saving with performance at full speed. Max power for max speed.
