Thread: About to give up on overclocking Q6600 - optimized defaults should work?




  1. #1

    Default About to give up on overclocking Q6600 - optimized defaults should work?

    So if I do not overclock anything with my CPU should optimized BIOS defaults work just fine with no tweaks for 4 x 1 GB RAM? That way I do not need to mess with MCH Core, MCH Reference, CPU Term, etc.?

    Not necessarily, 4 DIMMs do not always work easily. For exapmple I tried 4x2GB a few days ago and it wouldn't pass Prime 95 unless I put a Corsair Airflow fan on the RAM, and this was on an open test bench with 21C room temperature, inside a case it would have been worse. With the fan it was stable for more than 24 hours (aborted then without errors) while without the fan I got errors in one hour.

    Heat may be an issue or you may need to increase some mainboard voltages.

    Any suggestions on what may need to be tweaked besides RAM voltages? I will be using Q6600, 4 x 1 GB RAM, ATI 4870 1GB video card --> temps never an issue with my Coolermaster case and 8 fans blowing (when was overclocked previously to 3.0 GHz on another brand mobo temps were only 45 under Orthos stress).

    I just want the most trouble-free settings for stock Q6600 if that exists, hehe

    Temps are not an issue for my CPU either on my open test bench, but is for the RAM they are because RAM usually doesn't ahve a fan directly blowing at it. If no fan blows directly on the RAM so that the air between the sticks gets moved then they can overheat. So unless you ahve a fan in your side panel directly blowing at the RAM then heat may be an issue like it was for me.
    You may need to increase MCH Core, but that's the only voltage other than RAM voltage that's usually necessary. Someone did actually have his rig run better when he decreased MCH Core by 0.05V below stock.
    Every piece of hardware is unique and 4 DIMMs can be as demanding for your board as overclocking itself, so stock settings don't always do the job and there are no settings that work for everyone.

    Also please list your hardware in your signature, it helps to know what exactly you're running.

    Fixed my sig :) I have 2 side case fans blowing on the RAM and one from the front

    Well then temps are not an issue I guess. Have youa ctually ahd problems with 4x1GB at stock speed or haven't you tried that yet?

    At optmized defaults and the CPU not overclocked I did get a BSOD at Windows green bars. Of course I had not touched the MCH Core at all. All 4 sticks test out just fine.

    MCH core bumped up and still got BSOD. Is there such a thing as RAM vdroop also? I did notice my RAM is rated for 2.2v and I have seen many posts where folks could not run 4-4--4-12 with any less than that. I had set it at 2.1 and noticed in Everest it was actually 2.06.

    Now that I have set RAM voltage to 2.24 it is reading 2.2v in Everest and BSOD is gone so far.

    Just try 5-5-5-18 for the timings, the difference between 4-4-4-12 and that is not noticeable, see my sig for some benchmarks.
    If DDR2 800 at 5-5-5-18 with the CPU at stock doesn't work then you the overclocked CPU never was your problem.
    If I were you I would just get a cheap 2x2GB kit sell the 4x1GB and overclock that CPU.

    Please link me to your ram or give me the model # and I can give you some suggested settings.

    I find 4x1 overclocks and handles timings much better then 2x2, but then again I am speaking Memory overclocks here

    MCH Voltage is likely a must, but MCH ref may or may not be. You may also have some incorrect advanced timings if you are using AUTO.

    So please post me a screenshot of This app running as well so I can see what AUTO is giving you for some of your memory timings >>>
    Tweakers.fr ~ Memset

    Also let me know what you are using now, so I can see how you have your CPU setup >>>

    This is Just a template I use to ask people their settings, pay no attention to the numbers in it, replace with yours
