  • Need help, F3-12800CL7-2GBRH on P7P55D-Evo

    Hi GSkill,


    I've been having many stability problems when running a certain game, an MMO that kept crashing madly (you can guess which). Contacting the MMO company, and following endless tech-support email ping-pong, I was told that to receive support I need to reach a 1:1 FSB : DRAM Freq ratio, for stability sake.

    Being an overclocking newb (not n00b) that I am, I set about a small research into what I should do. I've gotten the latest BIOS + drivers to everything to begin with, and I am interested in getting to the golden 1:1 without any special OC (my rig is powerful enough as it is for now).

    Starting with a ratio of 1:5 (FSB 133Mhz, DRAM at 666Mhz), and wanting the CPU (stocked at 2.66Ghz) to run at 2.8Ghz, I tried the following settings:

    Ai Overclocking Tuner: X. M. P. (as per your recommendation I've read)
    FSB: 200Mhz
    CPU multiplier: 14 (= CPU @ nice solid 2.8Ghz)

    With this I've gotten to a ratio of 2:8 (why isn't it 1:4 by the way? ...)


    I have several questions:

    1. Cpu-Z states that the X.M.P. profile of the memory should be: 7.0-7-7-24-34-2T
    But my board will only set it to 7.0-7-7-24-89-2T (tRFC = 89 here)
    Value tRFC 79 being the lowest stable, and nothing close to Cpu-Z's 34
    Is this anything to worry about? how does this affect the memory frequency?

    2. On the Memory tab, field Channels # shows "Dual" which is good, but field DC Mode is empty instead of showing "Symmetrical".
    Is this a problem?

    3. I can't, for the life of me, get the ratio to anything closer to 1:1. 2:8 currently is the best I can.
    - Is there anything I can do without completely crippling my system?
    - If this isn't possible to reach, can you please write it so I may show the game company?
    - How do I change the DRAM frequency, or is it only a result of some calculation with the many timing values and cannot be changed directly?




    Thank you very much in advance,
    Awaiting reply,
    Spade_of_Blue

    You are misinformed.

    1. 34 is tRC not tRFC. tRFC at 79-89 is normal.

    2. Yes, this is fine.

    3. Tell the MMO company they are giving bogus "support" if they are really telling people to set up their computer differently, especially "1:1 ratio". Your computer is not old LGA775 or previous that can do 1:1. These new systems are locked, so your ratio can only be... 2:6, 2:8, 2:10, and 2:12 if you have i7 CPU.

    DRAM Frequency is changed directly. Set XMP Profile to Manual or XMP, and it should have the option "DRAM Frequency".

    With XMP enabled, your CPU and memory performance is good enough for all games. You do NOT need 1:1 FSBRAM Ratio.. that's the first time I've heard that from a game company.. haha

      Thank you - you are my hero!

      The game is World of Warcraft - and here is what their support is sending:



      ------------------ Start of email from Blizzard, 01-Sep-2010 ------------------


      Hello <my name here>,


      Thank you for your reply.

      Looking at the files you've provided, it appears that the memory frequency that your RAM is running at isn't supported by the CPU that you're using.

      Your RAM is running at 667Mhz whereas the FSB is expecting it to be running at 133Mhz

      This is often one of the causes of .adt errors such as those you're experiencing.

      As altering this information in the BIOS is a very advanced step, we would recommend contacting a computer technician about altering these values so that they're synchronised.

      Please try the game after altering these, do not hesitate to contact us further if the issue persists.

      Best regards,

      I wonder if they'll give me support after this thread here from a professional...
      (I originally requested my subscription money back for their game's crashes, and they refused)


      Thanks,

        Well go ahead and configure properly (XMP), and try again. If it still has the same problem, then you can say we made sure the computer is working properly, then see what else they may say..

          An update;


          Days have past since and I have been completely ignored by the company.
          They have not responded to my email that 2:8 is normal, my 20 hour flawless Prime95 torture test, nor any of my subsequent email reminders ("I have not received a reply please review").



          Needless to say I will not remain a customer of Blizzard on any product. I have not purchased Starcraft II and I have not pre-ordered WoW Cataclysm.
          I will not do those. Ever.



          Once again GSkill, thank you for a good to-the-point support,

            Very odd, still don't see why it would crash. What Windows OS are you using? Maybe create a new partition, install the game on a fresh Win install and see how that goes. The problem lies somewhere, so hopefully we can isolate it. To give them the benefit of the doubt, I don't they would release an unstable game, otherwise I'm sure you're not the only one with a problem.

            Thank you

              value of tRFC

              Originally posted by GSKILL TECH View Post

              Hi,
              I have similar RAM and Board:

              - F3-12800CL7 2x4GB (black)
              - F3-12800CL7 2x2GB (blue)
              - Asus P7P55D-E Evo

              The RAM works as 12GB and CL7-8-7-24 2T @1.65V, but after adding the black ones to the blue, my tRFC raised up to 128. Is it still common to have such a value when installed all 4 slots?

              and second:
              Now I know that tRC is something different, but how can I adjust this in BIOS? How can I be sure the board did it correct, because the timings and voltage were set wrong when the board did it auto, I had to set them manually.

              Comment


              • #8
                Yes, tRFC is very normal for 4 modules installed.

                AUTO set timings to anything, that's why it is important to manually set them. The motherboard will only operate at what you set it at.

                Thank you
