Thread: Wierd Freezing issue after OC

    Default Wierd Freezing issue after OC

    I am having a very strange problem with my overclock, in windows the screen will freeze and my mouse and keyboard will not have power to them anymore and the only way to fix is a reboot. I have a q9650 so I decided to give it an OC. I had resisted the temptation to do so because I thought 3.0ghz quad core who could need more? So I changed the bus speed to 400, then upped the voltage on the vcore to 1.25000, I also upped the voltage on the FSB 0.05. I then changed the ram timings to auto for a 400FSB, this is where I think the problems lay. I dont know enough about latency timings to adjust them manually. Also I upped the voltage +0.2 volts on the ram and then it froze and then I tried +0.25 and it froze again so now I am back down at +0.2. I have disabled the speedstep features and the voltage regulation feature.

    Additional info I ran Memtest 2.1.1 for 4-5 hours with 15-20 complete passes with no errors. Also I can run cpu intensive programs such as prime95 for hours with no freezing. This seems to happen randomly like sometimes 4-5 minutes in other times it doesnt happen for hours. Also there are no entries in the event viewer saying what happened before the freeze. This is a very strange problem and I really dont know what I can do to fix it so any help would be appreciated.

    System:
    intel q9650 @ 3.6 400x9 1.25vcore
    Corsair x1333 ram timings autoset 10-10-10-26 1:2 ratio
    voltage @ either +0.2 or +0.25
    PSU: Zalman 750 watt w/heat pipes
    Mobo: Gigabyte X48-DQ6 with F6D bios
    Nvidia 9800 gx2 EVGA

    I just got my board to run at 500MHz last night after a week of failures. What turned the tide? Lots of reading, especially of the suggested BIOS settings. One thing that I think made a difference was the settings that are suggested to be 1/2 the voltage of your memory. Default memory voltage for DDR2 is 1.8, so suto was setting .9. My memory works at 2.1, so I manually set them to 1.05. I am not saying that this is your problem, what I am saying is that you have to research and understand what the settings do and how they interact before you can even begin to establish a solid overclock of any magnitude. There is no silver bullet, although you can reeive many suggestions.

    I have done plenty of reading about overclocking before I attempted this, my system was running stock for over half a year without any alterations. I have read how to overclock core 2 quads on the internet but their ram timings all involve DDR2 which runs at much lower timings than ddr3. Should I post all of my bios settings for the forum to see? This has happened still today after i searched the forum for "q9650 overclocking" and there is no one with my exact configuration and motherboard. I looked in the solutions for them and they said to increase voltages that are not called the same thing in my bios. One particually was the G(mCH) voltage and I increased that and its still freezing.

    Use the template and post your settings, otherwise, everyone will be, basically, guessing. (G)mCH Voltage is actually (g)MCH Frequency Latch, and is in the BIOS Guide. It locks in a strap to pick memory dividers from, whereas System Memory Multiplier picks the divider and strap. If you are setting your multiplier manually, leave (g)MCH Frq Latch on auto.

    Sorry, somehow overlooked that you were not using a P35 or P45 board. Please, disregard my comment about (g)MCH.
    Any particular reason you are running your PCIe at 102 instead of 100? Migth try 100. CPU Voltage might be a little low for that FSB. Hard to tell without your timings and other voltages.

    my timings are auto set by the board hence the performance enhanced with 4.00D and DRAM timings are set to auto

    as for the voltage for the CPU a lot of different sites i have read about q9650s have gotten upwards of 3.8 on this voltage
