  • F3-17000CL11D-8GBXL + Gigabyte GA-890GPA-UD3H(rev2.1) + AMD Phenom II X6 1100T

    Hello!
    What are the optimal BIOS settings for 1866MHz or even higher (as my MB has support for 1866+)?
    Do I need to manually set any other voltage, or just the DRAM and CPUNB?
    Can the timings be tightened at 1866, since 11-11-11-30 is rated for 2133?
    Also, how much does the Command Rate and the DIMM Trfc (ns) affect?
    Currently I have it all auto in the BIOS, I am at 1600MHz 11-11-11-28 trC 39 & CR 1T.
    I had manually set the CPU clock at 233 with HT Link Width 2330, to achieve 1866 (1864 in BIOS) with DRAM Voltage@1.6 and auto timings, and while it worked and passed a stability test, Windows popped a BlueScreen and decided to leave all to Auto, until I get access to the forum.
    Also, the dimms are in 2 & 4 slots (strangely, CPU-Z says 3 & 4).

    Thanks in advance!

    P.S. I now realised that I hadn't raised the CPUNB Voltage, but only the CPUPLL Voltage, as the CPU is also being overclocked.

    Most Pre-FX amd processors cant reach DDR3-2133 at all. A lot of them does not even get to DDR3-1866 but maxes around DDR3-1800 (900MHz). With your kit i would try to find fast timings for DDR3-1600 first. Try:

    9-10-9-27
    9-9-9-24
    8-9-9-24
    8-9-8-24
    7-9-8-24
    8-8-8-24
    7-8-8-24
    7-8-7-24

    You can leave tRC at 39 and voltage at 1.60V for that.

    Then with 11-11-11-28 and 1.60V set, raise your BCLK in small steps towards your desired effective memory clock (like 870, 880, 890, 900, 910...). If you find a certain wall, where neither a higher memory voltage nor loosend timings get you any further, try to tighten the timings at that frequency

    11-11-11-28
    10-11-10-28
    9-11-10-27
    10-10-10-27
    9-10-10-27
    9-10-9-27
    8-10-9-27
    9-9-9-27
    8-9-9-27
    8-9-8-27

    Then compare effective performance to your tweaked setting for DDR3-1600.

    ps: Sorry i cant be more specific about possible timings, because i don't know what type of IC your memroy uses

      Thanks a lot emissary42, I will try your suggestions and post back! Don't worry, you 've been enough specific, I will tweak them around myself.

        It doesn't accept lower timings than 11-11-11-28@1600MHz...

          What do you mean? DDR3-1600 it should be capable of CL10, CL9, CL8.

          Don't forget to increase CPU-NB Frequency along with CPU-NB Voltage (if necessary).

          Take a look at this guide:

            Thank you!

            You 've been most helpful! I will try your directions asap! More or less, I have tried similar steps myself and my MB wouldn't accept them (during reboot it beeped 3 times and reverted back to default), but I will follow the steps exactly and post back!

              Returning Post

              After a long time, I came back to share my results!
              I had it running with these settings, since the last time I posted (following your suggestions, with a little testing of my own):
              CPU FSB : 233 MHz
              CPU Multiplier : x15 = 3495 MHz & x17 = 3961 MHz (Turbo)
              Northbridge Multiplier : x12 = 2796 MHz
              HT Link Multiplier : x12 = 2796 MHz
              Memory Clock : x8 = 1864 MHz
              DRAM configuration : Unganged with Auto Settings 11-11-11-28 CR1
              DRAM Voltage : 1.590 V (which shows as 1.6 V at the PC Health tab of the BIOS and also at CPU-Z, Aida 64 etc - I find that a little strange, because when I had it set at 1.65 V with my previous RAM, it showed it accurately)
              CPU NB VID : +0.125 V (it crashed at startup with +0.100 V)
              CPU Voltage : +0.050 V (I thought to raise that a bit because the CPU works at higher frequencies than stock)
              Bios Version : FF

              I thought it was running stable at these settings, I also run MemTest x86 for 3 passes and the AIDA 64 System Stability Test with no errors or shutdowns, but some problems have emerged, and I am currently troubleshooting!
              Firstly, Windows 7 64Bit (my previous installation) was crashing some times when playing a game and even during a Skype call. I thought at first it may be a GPU driver issue, but kept crashing when I reinstalled it. Then I was blaming Comodo Internet Security, because there was an ActiveX/COM registry issue (CCleaner) named CIS.Debug.Injector, that I thought caused a system freeze when Direct 3D applications , because when I deleted it, the system didn't crash, but it showed up after each restart, so I left it alone. Then Comodo let a malware run (Win.32.Sality.Gen) which spread on my hard drives, I cleaned with Kaspersky Rescue Disk, but it had ****ed up the installation and drivers, so I decided to do a fresh install. I thought, because my hardware works fine, that my problems would end!
              Since then, for over a year now, I have it running with the BIOS auto settings.
              1607 MHz @ 1.5V with 11-11-11-28 timings, I have only manually set Northbridge & HT Link at 2400 MHz, and it has been running fast and ultra stable. The read, write, copy speeds and latency in AIDA64 Benchmarks are lot better than the default for my 1100T.
              Also, System Disk is a Samsung EVO 250GB. With RAPID enabled, gives 3000MB/s read & 2500 MB/s write. I believe these results are due to this awesome G-Skill RAM! I attached a MaxxMem2 benchmark. Note that I couldn't find lower timings for 1600 MHz, maybe I should raise the voltages, but it worked with lower voltages at 1866 MHz, so I didn't want to push more.
              Now, I believe my error was that I left Turbo Frequency & Turbo CPB enabled...
              I'm thinking now, with the above disabled, to try to find settings for 1866 MHz with lower timings! I believe these (http://www.newegg.com/global/ie/Prod...82E16820231455) are similar, so would it possible to achieve 9-10-9-28 @ 1.5V ? Command Rate 1 or 2 is better?
              What does the community think?
              Thanks a lot in advance, for your suggestions!

                Yes, it is possible. Give it a shot to see what you can achieve.
