  • Gigabyte 990FXA-UD3 + FX-4170 + F3-17600CL7D-4GBPIS

    Here is my attempt to max out on the Gigabyte GA-990FXA-UD3 rev.1.0 with Air cooling only but still have a rock-stable system:
    AMD FX-4170 running at 4.88GHz (22X)
    RAM G.Skill Pi 4Gb (2x2Gb in slots 2 and 4) 2200MHz F3-17600CL7D-4GBPIS running at 2367MHz
    CPU Core Clock at 222MHz
    NB at 2442MHz (11X)
    HT FSB at 2664MHz (12x)
    Vdimm setting at 1.710volts
    Vnb-vid setting at +0.100v
    Vcpu at +0.075v
    RAM clocks at 7-10-8-24-33
    CPU cooled with Xigmatek Dark Knight
    RAM cooled with G.Skill Turbulence II Dual LED Fan
    SB cooled with 50mm fan
    Mosfet heatsink cooled with Asus Mosfet Fan

    Any attempts to get 2378-2400MHz may get boot to Win7x64 but it becomes unstable under load and either crashes a program or I get BSOD.

    Hope this helps alone but if you have suggestions to get higher frequencies as some Intel tweakers have (2600MHz+), let me know!

    The NB has your MC (memory controller) could try raiisng it's voltage, might have a little extra play available in DRAM voltage also

      Yeah, tried those. Vnb adjustments just destabilize my system Seems that 2378MHz is some kind of wall that needs multiple adjustments or maybe one magical variation I haven't tried yet.
      The best I got at 2378MHz was 30 minutes of stability. I then ran my antivirus program and the system crashed half-way through it.
      I bumped the Vdimm to 1.725v and relaxed the memory timings to 7-10-10-28-6-90/110-10-6-40-6

      Tried lowering the memory multiplier to 9.33 as hinted by the EOCP BIOS settings. Bumped the Base Clock to 257MHz and got the same results.

      If I have to relax CL7 to CL8, then it's not worth it.
      I'm thinking that I would need better cooling on my NB. I only have the small stock heatsink, while the UD5 and UD7 have the heatpipe system as stock. If only those heatsink-heatpipe units were available in the aftermarkets...

        With the OC in place could go CL8, the increased bandwidth with a higher OC can overcome the looser CL in overall performance

          Hmm....Well I was able to boot stably to 2416MHz using the following settings:
          Memory Multiplier = 12.0X
          Base Clock = Auto-200
          Latencies at 8-11-8-28-6-90/110-10-6-40-6
          Vdimm = 1.715v
          Vnb-vid = +0.125v
          Vcpu = +0.075
          NB = 2617MHz
          HTT = 2617MHz
          4.93GHz CPU

          Maxxmem Benchmarks were a bit higher at 15013/12110/11732/11.92/50.9

          The higher stable NB frequency of 2617MHz is probably the best compensation boost to the lower latencies. I'll now see if I can tighten some timings, keeping the same voltages...

              Well, I've had to scale back to 2336MHz.
              7-10-7-24-33; NB=2409MHz; HTT=2628MHz; Vdimm= 1.685; Vnb-vid=+0.075; Vcpu=+0.075

              Prolonged use at 2400MHz generated program crashes.
              Also, frequencies of 2342-2378MHZ would not allow a crash-free 2D Blu-ray playback, given my settings.

              I was trying to navigate within a framework of solidity and certainty that nothing I did on the computer would fail.

              But It was a good learning experience for future and faster DRAM !

                That's a thing a like about systems, your are constantly learning more and more, and just about on a daily basis

                  you might want to use 7-11-x timings as 1180MHz is right where tRCD 10 usually stops on PSC

                    Closer To Success at 2400MHz RAM

                    I've gotten a little closer now that this RAM is gelling into my system.
                    4.80Ghz CPU = 24.5x200
                    2400MHz RAM - 12.0x200
                    CPU Core manually-locked to 200MHz
                    NB at 2600MHz
                    HTT at 2600MHz
                    Vdram= 1.730v
                    Vcpu= +0.750v
                    Vnb-vid=+0.125v
                    Vnb=1.150v
                    Timings at 8-11-8-28-6-90/100ns-10-6-40-6
                    Maxxmem results at:
                    15257
                    11912
                    11608
                    11.76
                    51.6
                    I've only had one BSOD in one week. 2D Blu-Ray playback is rock-stable.

                        The air-cooled CPU temps were never an issue as I am able to keep it to 50C max (for CPU Socket Temp and 37C max for Internal CPU Temp) within my 2D world.
                        The NB is never physically too hot to touch even at 2600MHz (Bios F5 and later seemed to fix any issues there).
                        I'm just taking a little longer to burn any new settings in as I am seeking stability within my usage patterns. Change can upset the system but the system sometimes finds a nice equilibrium point. I did follow your advice and yup...patience rewards the hopeful!
                        My next step is to install a Phanteks PH-TC14PE that should cools things even better.
